This one could be made in quantity for about a $5 parts cost, and it is only a little bit more expensive if you are making just a few. I won't kid you that this is an easy design to make - don't try it unless you have very good soldering skills and some experience in electronics. Some of the components here are smaller than grains of rice, so it would be useful to have good eyesight as well! Like the flashlight card, it is more of a proof of concept than something you can churn out in quantity, but it might at least give you an idea of what can be achieved, and where business cards might be in just a few years time.<br /><br /><object width="500" height="411"><param name="movie" value="http://video.google.com/googleplayer.swf?docId=4920150912461662505"><param name="wmode" value="transparent"><embed src="http://video.google.com/googleplayer.swf?docId=4920150912461662505" type="application/x-shockwave-flash" width="500" height="411"></embed></object><br /><table align="center"><tbody><tr><td><div id="spot149010" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FR4/T0M5/FKD1LQRF/FR4T0M5FKD1LQRF.MEDIUM.jpg" galleryimg="NO" alt="Matrix11.jpg" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">500x324 : FR4T0M5FKD1LQRF (0)</div><a href="http://www.instructables.com/file/FR4T0M5FKD1LQRF/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot149010 = new ImageSpot( 'spot149010', { loadID: 'FR4T0M5FKD1LQRF', loadIMG: '/files/deriv/FR4/T0M5/FKD1LQRF/FR4T0M5FKD1LQRF.MEDIUM.jpg', altString: 'Matrix11.jpg', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot149010, {"imageID":"FR4T0M5FKD1LQRF","name":"Matrix11.jpg","imageURL":"/files/deriv/FR4/T0M5/FKD1LQRF/FR4T0M5FKD1LQRF.MEDIUM.jpg","showURL":"/file/FR4T0M5FKD1LQRF/","description":null,"length":59813,"width":570,"height":369} ); InstructJS.cachedRefs.spotspot149010=spotspot149010; });</script> </td></tr></tbody></table><div style="margin-bottom: 15px;"><h2><a href="http://www.instructables.com/id/S88H0GFFKFUGGNL/" name="step1"><span class="stepLabel" style="padding-right: 5px;">step 1</span><span class="stepTitle">About The Design</span></a></h2><div class="txt">This is the sort of card that would suit a high-tech business, or those who were involved in high-value contracts, where an innovative image is all important. I would never suggest that it would replace a conventional business card, but to impress that all-important prospective client, there would be more than a few companies who would be happy to spend just an extra few dollars. Like the flashlight card, the aim is to design a business card that people just can't throw away!<br /><br />The design is really quite simple for what it does - a matrix of 5x15 LEDs, connected to a single-chip "PIC"microcontroller. A handful of resistors and switches complete the design (Schematic available below). By keeping the microcontroller in sleep mode unless the buttons are pressed, the battery can last several years, and still allow a couple of thousand displays of your messages.<br /></div><table align="center"><tbody><tr><td><div id="spot149011" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FR4/T0M5/FKD1LQRF/FR4T0M5FKD1LQRF.MEDIUM.jpg" galleryimg="NO" alt="Matrix11.jpg" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">500x324 : FR4T0M5FKD1LQRF (0)</div><a href="http://www.instructables.com/file/FR4T0M5FKD1LQRF/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot149011 = new ImageSpot( 'spot149011', { loadID: 'FR4T0M5FKD1LQRF', loadIMG: '/files/deriv/FR4/T0M5/FKD1LQRF/FR4T0M5FKD1LQRF.MEDIUM.jpg', altString: 'Matrix11.jpg', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot149011, {"imageID":"FR4T0M5FKD1LQRF","name":"Matrix11.jpg","imageURL":"/files/deriv/FR4/T0M5/FKD1LQRF/FR4T0M5FKD1LQRF.MEDIUM.jpg","showURL":"/file/FR4T0M5FKD1LQRF/","description":null,"length":59813,"width":570,"height":369} ); InstructJS.cachedRefs.spotspot149011=spotspot149011; });</script> <div class="spotThumbs" style="margin-top: 4px; margin-bottom: 4px;"><a href="http://www.instructables.com/id/Dot_Matrix_Business_Card/?ALLSTEPS#" onclick="return false;" id="imgThumb_spot149011_FR4T0M5FKD1LQRF"><img src="http://www.instructables.com/files/deriv/FR4/T0M5/FKD1LQRF/FR4T0M5FKD1LQRF.THUMB.jpg" alt="Matrix11.jpg" title="" /></a></div><script> InstructJS.load(['imagespot'], function () { var spot = ImageSpots.get('spot149011'); $("imgThumb_spot149011_FR4T0M5FKD1LQRF").observe("click", function() { ImageSpots.show( 'spot149011', 'FR4T0M5FKD1LQRF' ); }); }); </script><div class="entryExtra"><a href="http://www.instructables.com/files/orig/F5E/OJHY/FKD1LQT7/F5EOJHYFKD1LQT7.pdf"><img src="http://www.instructables.com/static/defaultIMG/file/PDF.gif" alt="" /><span class="entryExtraTitle">MatrixSchematic.pdf</span></a><a href="http://www.instructables.com/file/F5EOJHYFKD1LQT7/">(595x842) 101 KB</a></div></td></tr></tbody></table></div><div style="margin-bottom: 15px;"><h2><a href="http://www.instructables.com/id/SHPIV4UFKFUGGQK/" name="step2"><span class="stepLabel" style="padding-right: 5px;">step 2</span><span class="stepTitle">What you need</span></a></h2><div class="txt"><ul><li> One CR2032 battery (I got them for about 16 cents on ebay when I bought 100)</li><br /><li> One CR2032 battery holder (I used part 18-3780 from www.rapidonline.com.

I printed on OHP transparency film. You will also need a way of programming the PIC microcontroller. I use the PICKit2 which is part number 579-PG164120 from www.mouser.com, and available at around $35.

A pair of tweezers is useful here - by putting a blob of solder on a pad, and then re-melting it whilst positioning the resistors or capacitors with the tweezers, you can neatly add these small components. It doesn't matter which way around these components go, but it does for the PIC (which should read with the writing the correct way up as shown in these photos), and also the LEDs must be put around the right way. It is harder to tell with the LEDs which way around they should go - the top connection should be the positive (or "anode"). You can tell by consulting the datasheet for the LED - one of the two leads will usually be marked in some way. An easier way is sometimes to test one of them by attaching a couple of wires to a small 1.5V battery, and then touching the leads on the ends of the LEDs - if it is the right way around, you should see a glow, but if using a single 1.5V battery, it will be extremely faint, so you will have to observe carefully. Again, a tutorial on soldering is not within the scope of this article - I did warn you that this isn't a beginner's project, so don't make this one your first venture into surface mount soldering! Note that the LEDs are only initially soldered on their bottom lead - we will use some wires later to connect their top leads.<br /></div><table align="center"><tbody><tr><td><div id="spot149013" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FRU/BQO7/FKD1LQTC/FRUBQO7FKD1LQTC.MEDIUM.jpg" galleryimg="NO" alt="Matrix2.JPG" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">500x321 : FRUBQO7FKD1LQTC (0)</div><a href="http://www.instructables.com/file/FRUBQO7FKD1LQTC/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot149013 = new ImageSpot( 'spot149013', { loadID: 'FRUBQO7FKD1LQTC', loadIMG: '/files/deriv/FRU/BQO7/FKD1LQTC/FRUBQO7FKD1LQTC.MEDIUM.jpg', altString: 'Matrix2.JPG', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot149013, {"imageID":"FRUBQO7FKD1LQTC","name":"Matrix2.JPG","imageURL":"/files/deriv/FRU/BQO7/FKD1LQTC/FRUBQO7FKD1LQTC.MEDIUM.jpg","showURL":"/file/FRUBQO7FKD1LQTC/","description":null,"length":99089,"width":500,"height":321} ); new ImageInfo( spotspot149013, {"imageID":"FJPHRU4FKD1LQTA","name":"MatrixLayout.jpg","imageURL":"/files/deriv/FJP/HRU4/FKD1LQTA/FJPHRU4FKD1LQTA.MEDIUM.jpg","showURL":"/file/FJPHRU4FKD1LQTA/","description":null,"length":105266,"width":500,"height":299} ); InstructJS.cachedRefs.spotspot149013=spotspot149013; });</script> <div class="spotThumbs" style="margin-top: 4px; margin-bottom: 4px;"><a href="http://www.instructables.com/id/Dot_Matrix_Business_Card/?ALLSTEPS#" onclick="return false;" id="imgThumb_spot149013_FRUBQO7FKD1LQTC"><img src="http://www.instructables.com/files/deriv/FRU/BQO7/FKD1LQTC/FRUBQO7FKD1LQTC.THUMB.jpg" alt="Matrix2.JPG" title="" /></a><a href="http://www.instructables.com/id/Dot_Matrix_Business_Card/?ALLSTEPS#" onclick="return false;" id="imgThumb_spot149013_FJPHRU4FKD1LQTA"><img src="http://www.instructables.com/files/deriv/FJP/HRU4/FKD1LQTA/FJPHRU4FKD1LQTA.THUMB.jpg" alt="MatrixLayout.jpg" title="" /></a></div><script> InstructJS.load(['imagespot'], function () { var spot = ImageSpots.get('spot149013'); $("imgThumb_spot149013_FRUBQO7FKD1LQTC").observe("click", function() { ImageSpots.show( 'spot149013', 'FRUBQO7FKD1LQTC' ); }); $("imgThumb_spot149013_FJPHRU4FKD1LQTA").observe("click", function() { ImageSpots.show( 'spot149013', 'FJPHRU4FKD1LQTA' ); }); }); </script></td></tr></tbody></table></div><div style="margin-bottom: 15px;"><h2><a href="http://www.instructables.com/id/SP27C3HFKD1LQVG/" name="step4"><span class="stepLabel" style="padding-right: 5px;">step 4</span><span class="stepTitle">An ad-hoc double sided board</span></a></h2><div class="txt">Lay some fine strips of 'invisible tape' down along the vertical PCB traces next to each column of LEDs - this will stop the wires we are about to solder touching them.<br /><br />Next, solder some fine tinned copper wire along the top of each row of LEDs, to reach all the way to the resistor as in the photo.

If you have bought the PIC Kit 2 programmer, it has everything you need with it. Download the MatrixCode.zip file from this page, unzip it and put it in a directory somewhere on your computer - then from within the MPLAB IDE, go to the "Project" menu, select "Open", and navigate to the "main.asm" file. Change the stored messages (around line 115 in the code) to your contact details rather than mine(!) - the messages are spelt out with a series of '1's and '0's - a '1' means the LED is on. If you look closely, you will see my name spelt out with '1's. (You might need to turn your head 90 degrees to see this!) You have complete freedom to make your own characters or symbols, so you could have, for example, a simple animation of a car moving to the left if you wanted. Note that there are four messages - one for each button - you will need to specify the length of each message by stating the number of columns it takes up in the 'MSG1LEN,MSG2LEN...' definitions.<br /><br />Go to the "Project" menu again, and select "Quickbuild" - check there are no errors, and you are then ready to program. I use a simple technique of inserting a broken-off strip of 5 pins from a strip of 0.1" header pins into the programmer, and then just touching the 5 pins whilst programming. This is a little fiddly, but as the erase or program cycle only takes a second or so, it is quite manageable. The arrow on the end pin of the programmer should align with the top pin of the PCB (NOT AS SHOWN IN THIS PHOTO - WHOOPS!) If you are experimenting, it is well worth soldering the strip of 5 pins onto the board until you have finished your changes. When you are ready to program, you will have to use the separate 'PICKIT2' utility supplied with the programmer, as for some reason, the MPLAB IDE doesn't support programming of the PIC16F57 directly. To do this, you need to specifify the family of PICs ("baseline"), and the particular part (16F57), before loading the Hex file created in the previous step, and then finally programming the chip. If all is successful, you should be able to insert the battery (positive side down), and press one of the buttons to see your message scroll along!<br /></div><table align="center"><tbody><tr><td><div id="spot149015" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FLD/7SIC/FKD1LQT5/FLD7SICFKD1LQT5.MEDIUM.jpg" galleryimg="NO" alt="Matrix4.JPG" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">500x393 : FLD7SICFKD1LQT5 (0)</div><a href="http://www.instructables.com/file/FLD7SICFKD1LQT5/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot149015 = new ImageSpot( 'spot149015', { loadID: 'FLD7SICFKD1LQT5', loadIMG: '/files/deriv/FLD/7SIC/FKD1LQT5/FLD7SICFKD1LQT5.MEDIUM.jpg', altString: 'Matrix4.JPG', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot149015, {"imageID":"FLD7SICFKD1LQT5","name":"Matrix4.JPG","imageURL":"/files/deriv/FLD/7SIC/FKD1LQT5/FLD7SICFKD1LQT5.MEDIUM.jpg","showURL":"/file/FLD7SICFKD1LQT5/","description":null,"length":76574,"width":500,"height":393} ); InstructJS.cachedRefs.spotspot149015=spotspot149015; });</script> <div class="spotThumbs" style="margin-top: 4px; margin-bottom: 4px;"><a href="http://www.instructables.com/id/Dot_Matrix_Business_Card/?ALLSTEPS#" onclick="return false;" id="imgThumb_spot149015_FLD7SICFKD1LQT5"><img src="http://www.instructables.com/files/deriv/FLD/7SIC/FKD1LQT5/FLD7SICFKD1LQT5.THUMB.jpg" alt="Matrix4.JPG" title="" /></a></div><script> InstructJS.load(['imagespot'], function () { var spot = ImageSpots.get('spot149015'); $("imgThumb_spot149015_FLD7SICFKD1LQT5").observe("click", function() { ImageSpots.show( 'spot149015', 'FLD7SICFKD1LQT5' ); }); }); </script><div class="entryExtra"><a href="http://www.instructables.com/files/orig/F69/J3QC/FKD1LQTB/F69J3QCFKD1LQTB.zip"><img src="http://www.instructables.com/static/defaultIMG/file/ZIP.gif" alt="" /><span class="entryExtraTitle">MatrixCode.zip</span></a><a href="http://www.instructables.com/file/F69J3QCFKD1LQTB/">19 KB</a></div></td></tr></tbody></table></div><div style="margin-bottom: 15px;"><h2><a href="http://www.instructables.com/id/SLMC21JFKD1LQW2/" name="step6"><span class="stepLabel" style="padding-right: 5px;">step 6</span><span class="stepTitle">Finishing Off</span></a></h2><div class="txt">To encapsulate the prototype, I applied some double sided foam tape to the board, turned it upside down, and then cut the excess off.

Firstly I would change the CR2032 cell to a CR2016 as this is thinner, and then embed it within a space cut in the PCB. By using lower-profile components, the thickness of the card could probably be reduced to about 1/8th of an inch (rather than the current 1/4 inch). By using some of the new thin-film batteries, it might even be possible to make a flexible card, albeit at a higher price. A professionally-printed overlay and a custom die-cut replacement for the foam tape would see the cards assembled much more quickly, and look a little slicker too. Of course the PCBs would be manufactured professionally as well, and populated by a 'pick and place' robot to allow assembly to be sped up even further.IVTAhttp://www.blogger.com/profile/01309771997733439396noreply@blogger.com2tag:blogger.com,1999:blog-7228078401792468600.post-8927910448037373912009-03-09T15:04:00.001-07:002009-03-09T15:09:57.875-07:00Make your own Lightning Globe<div class="txt">This instructable will show you how to make one of those cool lightning globes with about $5.00 worth of parts.<br /><br /><strong>WARNING</strong> Just like my <a href="http://www.instructables.com/id/Monitor-Hack---Security-System%21/">Monitor Hack instructable</a>, this makes use of some very high voltage.

It might be even more fun to use a marx generator than using a 'very complicated to build' tesla coil!<br /><br />And to let you know, this <a href="http://www.electricstuff.co.uk/marxgen.htm">"Quick & Dirty" Marx generator</a> website helped me a lot to build this marx generator.<br /><br />If you have no idea what is a marx generator, you might be saying this in your mind "What the hell is a marx generator!", <a href="http://en.wikipedia.org/wiki/Marx_generator">read about it here on Wikipedia</a>.<br /><br />WARNING! This project generates very high pulse discharge voltages, which can seriously harm and could be potentially lethal to you and others that are careless to touch the output of the marx generator.<br /><br /><div style="text-align: center;"> <object id="metacafeplayer" width="400" height="345"><param name="movie" value="http://www.metacafe.com/fplayer/1893979/marx_generator/.swf"><param name="wmode" value="transparent"><embed src="http://www.metacafe.com/fplayer/1893979/marx_generator/.swf" type="application/x-shockwave-flash" wmode="transparent" width="400" height="345"></embed></object></div><br /></div><table align="center"><tbody><tr><td><div id="spot148307" style="padding: 0px;

When all of the spark gaps fires (sparks), the capacitors get effectively connected in series, therefor multiplying the input voltage by the number of capacitors and causing a long spark at the end of the marx generator.<br /><br />Rb has a ballasting effect, it is used to prevent a continuous arc forming across the first gap - this prevents further firing of the marx generator. The value of the resistor will mainly depend on the type of power supply is used, in this case, we are going to use an 10M resistor for this marx generator on this instructable. However, you can reduce the Bb's value to try get more 'bangs per second' without causing an arc forming on the spark gap...<br /><br />Now, you know how it works (I hope), so lets build it!<br /></div><table align="center"><tbody><tr><td><div id="spot148308" style="padding: 0px;

If the spark from the marx generator bites you, your life is over...<br /><br />There is one thing you must know, a healthy human heart can only withstand electric currents maximum 10mA. Currents over 10mA can results death, I am NOT joking here, this is serous stuff, a lot of people thinks your heart can handle currents up to 500mA, THIS IS NOT TRUE!!! THEY ARE WRONG!!! If you don't believe me, then test your self against a high voltage 500mA power supply, a small microwave transformer would do, put your hand on one lead, put your other hand on the other lead, turn on the power supply and you will be sorry...<br /><br />The marx generator will also be dangerous after the power is turned off, because the capacitors will hold a lethal charge in them, so, MAKE ABSOLUTELY SURE YOU DRAIN ALL THE CAPACITORS BEFORE YOU TOUCH THE DEVICE!!! Otherwise you will get a 'surprise shock' form the capacitors which can seriously harm you or even death...<br /><br />Also, every time a marx generator fires (make a spark), it kicks out a lot of UV radiation, and sometimes X-rays! Staring at the sparks form the marx generator can cause problems with your eyes, so wear UV sunglasses or briefly watch it every once a while.<br /><br />Okay, you might be a bit scared after reading this horrible step, so do you think you can build a marx generator? Or find it too dangerous to build it? The choice is yours...<br /></div><table align="center"><tbody><tr><td><div id="spot148309" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FPX/OC65/FKD1HPA2/FPXOC65FKD1HPA2.MEDIUM.gif" galleryimg="NO" alt="DANGER58.gif" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">400x285 : FPXOC65FKD1HPA2 (0)</div><a href="http://www.instructables.com/file/FPXOC65FKD1HPA2/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot148309 = new ImageSpot( 'spot148309', { loadID: 'FPXOC65FKD1HPA2', loadIMG: '/files/deriv/FPX/OC65/FKD1HPA2/FPXOC65FKD1HPA2.MEDIUM.gif', altString: 'DANGER58.gif', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot148309, {"imageID":"FPXOC65FKD1HPA2","name":"DANGER58.gif","imageURL":"/files/deriv/FPX/OC65/FKD1HPA2/FPXOC65FKD1HPA2.MEDIUM.gif","showURL":"/file/FPXOC65FKD1HPA2/","description":null,"length":13392,"width":400,"height":285} ); InstructJS.cachedRefs.spotspot148309=spotspot148309; });</script> </td></tr></tbody></table></div><div style="margin-bottom: 15px;"><h2><a href="http://www.instructables.com/id/S1H091GFK91731H/" name="step3"><span class="stepLabel" style="padding-right: 5px;">step 3</span><span class="stepTitle">What you will need are...</span></a></h2><div class="txt">I based the components I had easily available.<br />The recommended components you should get are ceramic capacitors and 1M 1 watt resistors. The ceramic capacitors are best suited for this project, because they are cheap, readily available, and they are good for in pulse discharge circuits. Polypropylene pulse-rated capacitor would also work well, but are more expensive, and harder to find with high voltage ratings. The resistors should be about 1M and 1 watt type, the normal 1/4 watt resistors are very unsuitable, if used, it will cause arcing and the resistors will burn out and damage the marx generator, so use the 1 watt metal glazed or carbon film resistors is suitable.<br /><br />If in doubt, try building just a couple of stages first to see how well the parts you use will work before you buy more...<br /><br />But I will tell you what I used...<br /><br /><ul><li> Ten 1nF, 4Kv ceramic capacitors</li><li> Twenty 1M, 2 watt, 500v carbon film resistors (I brought the 2 watt resistors because they are somewhat cheaper then the 1 watt resistors!)</li><li> Two 4.7M, 1 watt, 3.5Kv metal glazed resistor for the Rb.</li><br /></ul>Also you can use a base for your marx generator, the best suited base are glass (too fragile), ceramic (it's breakable) plastics (ideal, but some of them may be conductive), or whatever you think it is good! I use wood, a very baaad idea (because wood is conductive), but I have no choice, wooden base or no base.<br /><br />You can use capacitors with larger values to get fatter, louder sparks, but take longer to recharge! You can often run capacitors in excess of their rated voltage, but obviously this increased the risk of failure!<br /><br />And don't forget, the size of sparks at the output gap will depend on the input voltage and number of stages...<br /><br /><strong>(UPDATE)</strong><br />I got all my components from <a href="http://www.farnell.com/">Farnell</a>.

If gaps are too close, especially near the supply end, you may see a continuous arc forming, preventing further operation. Increasing the gap on the first (and possibly second) stage may reduce the tendency to arc. Increasing the ballast resistor Rb also helps, at the expense of slower recharge time.<br /><br /><strong>Q. - My marx generator is not doing anything what so ever.</strong><br />A. - Is there something wrong with the inverter? Check it to see if it working or not.<br />A. - Did you make sure you built the marx generator properly?<br />A. - Did you miss out any connections?<br /><br /><strong>Q. - My marx generator is working, but after a few seconds, it made a "POP" noise, and it did not work again...</strong><br />A. - That is a bad sign, a capacitor may have been destroyed from excess voltage OR your HV power supply has been killed from the extremely high voltage spikes from the marx generator. Replace the capacitor/inverter and don't make that same mistake again...<br /><br /></div><table align="center"><tbody><tr><td><div id="spot148316" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FIM/RNEO/FKB3DRCT/FIMRNEOFKB3DRCT.MEDIUM.jpg" galleryimg="NO" alt="P1040056.JPG" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">500x375 : FIMRNEOFKB3DRCT (0)</div><a href="http://www.instructables.com/file/FIMRNEOFKB3DRCT/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot148316 = new ImageSpot( 'spot148316', { loadID: 'FIMRNEOFKB3DRCT', loadIMG: '/files/deriv/FIM/RNEO/FKB3DRCT/FIMRNEOFKB3DRCT.MEDIUM.jpg', altString: 'P1040056.JPG', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot148316, {"imageID":"FIMRNEOFKB3DRCT","name":"P1040056.JPG","imageURL":"/files/deriv/FIM/RNEO/FKB3DRCT/FIMRNEOFKB3DRCT.MEDIUM.jpg","showURL":"/file/FIMRNEOFKB3DRCT/","description":null,"length":392419,"width":1600,"height":1200} ); InstructJS.cachedRefs.spotspot148316=spotspot148316; });</script> </td></tr></tbody></table></div><h2><a href="http://www.instructables.com/id/S0AHLEBFKB3DTIZ/" name="step10"><span class="stepLabel" style="padding-right: 5px;">step 10</span><span class="stepTitle">SPARKS!!!</span></a></h2><div class="txt">My marx generator works very well, it generates loud, bright, sparks that are up to 2 inches long (5 cm)!

Plasma Speaker<div class="txt">Are you tired of those old black speakers that only just make sounds? Maybe sound reactive lights are just not enough to impress you?<br /><br />How about a Plasma Speaker?<br /><br />A plasma speaker is a device that generates an high voltage electrical arc that makes purple light <i>and</i> music! Without any speakers or any moving parts!<br /><br />Sounds too good to be true?<br />Well, you're wrong, the high voltage arc really does sing by vibrating in the air. (Of course, you will need to give the device musical audio for it to work.)<br />And just leave this instructable if you still don't believe me...<br /><br />And this is something I always wanted to build - I have been dreaming to build one for about 6 months, until Kiteman has greatly boosted my encouragement to build one. (Thanks Kiteman)<br /><br />The video of my plasma speaker - early prototype.<br /><div style="text-align: center;"> <object id="metacafeplayer" width="400" height="345"><param name="movie" value="http://www.metacafe.com/fplayer/1963063/plasma_speaker_early_prototype/.swf"><param name="wmode" value="transparent"><embed src="http://www.metacafe.com/fplayer/1963063/plasma_speaker_early_prototype/.swf" type="application/x-shockwave-flash" wmode="transparent" width="400" height="345"></embed></object></div><br /></div><table align="center"><tbody><tr><td><div id="spot148166" style="padding: 0px;

They are some safety features to prevent the spikes damaging the player, but they can fail... So I am not responsible if your player gets damaged, and use cheap players like CD players, if you're rich, you can use expensive players if you want. :-)<br /></div><table align="center"><tbody><tr><td><div id="spot148167" style="padding: 0px;

Then when you give it audio, the TL494 modulates the audio frequency into the main high frequency. Now the flyback transformer is being driven by the high frequency and the audio frequency, and when the arc is produced, the arc vibrates the air with both the audio and high frequency creating sounds.<br />If you tune up the 22K potentiometer, the high frequency increases, when it goes higher than 20KHz, we cannot hear it, but only the audio frequency...<br /><br />I hope you can kinda understand this..<br /></div><table align="center"><tbody><tr><td><div id="spot148169" style="padding: 0px;

If you want to play music on the arc, tune the frequency up until you don't hear it and play the music. Note: The 10K potentiometer does NOT affect the input audio (music).<br /><br />I am not too sure what the 22K potentiometer's job is, but it seems to change the volume of the audio, fiddle with the 22K potentiometer until you can hear the music loudly. Note: Making the music louder will shorten the length of the arc.<br /></div><table align="center"><tbody><tr><td><div id="spot148176" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FED/A5TU/FMZAIS5D/FEDA5TUFMZAIS5D.MEDIUM.jpg" galleryimg="NO" alt="P3090013_2.JPG" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">500x351 : FEDA5TUFMZAIS5D (0)</div><a href="http://www.instructables.com/file/FEDA5TUFMZAIS5D/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot148176 = new ImageSpot( 'spot148176', { loadID: 'FEDA5TUFMZAIS5D', loadIMG: '/files/deriv/FED/A5TU/FMZAIS5D/FEDA5TUFMZAIS5D.MEDIUM.jpg', altString: 'P3090013_2.JPG', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot148176, {"imageID":"FEDA5TUFMZAIS5D","name":"P3090013_2.JPG","imageURL":"/files/deriv/FED/A5TU/FMZAIS5D/FEDA5TUFMZAIS5D.MEDIUM.jpg","showURL":"/file/FEDA5TUFMZAIS5D/","description":null,"length":251545,"width":1200,"height":842} ); InstructJS.cachedRefs.spotspot148176=spotspot148176; });</script> </td></tr></tbody></table></div><h2><a href="http://www.instructables.com/id/SSQ0I08FMMCZ751/" name="step11"><span class="stepLabel" style="padding-right: 5px;">step 11</span><span class="stepTitle">Interesting discharges...</span></a></h2><div class="txt">Just a little story I like to tell you about...<br /><br />While I was testing (well, playing) my plasma speaker, the 12v battery is going flat and the arcs are becoming unimpressively short. So I replaced the battery with my lab PSU I modified from an ATX PSU and put an 22,000uF capacitor in parallel with its 12v output and ground.<br />The 22,000uF capacitor is used to adsorb any high voltage spikes that may appear on the line.<br /><br />When I connect the PSU's power to the plasma speaker and turned it on, guess what happened...<br /><br />The arc are very different, instead of a sting of purple light, the arc flaps furiously and it makes very interesting light display. But this is not suitable for a plasma speaker, because the arcs flaps so much it just simply drowned out the music...<br /><br />Here is a movie of the arcs.<br /><br /><div style="text-align: center;"> <object id="metacafeplayer" width="400" height="345"><param name="movie" value="http://www.metacafe.com/fplayer/1984427/flyback_arc/.swf"><param name="wmode" value="transparent"><embed src="http://www.metacafe.com/fplayer/1984427/flyback_arc/.swf" type="application/x-shockwave-flash" wmode="transparent" width="400" height="345"></embed></object></div><br /><br />Well, I hoped you enjoyed this instructable!<br />If you have any questions, or need help, or found an error, or anything, <sup>make a comment!

There are three ways to get started programing your Arduino Controlled Servo Robot - (SERB).<br /><br /><strong>Option 1: (Modifying SERB_Test.pde)</strong><br />Sometimes when programming the easiest thing to do is take a working program and start adding your own code to it. To do this download the SERB_Test zipped program (<i>07-(SERB)- SERB-Test Arduino Program.zip</i>). Proceed to unzip this in your Arduino sketch folder (default "My Documents\Arduino\"). Finally open the Arduino programming environment and download it to your Arduino. The code is well commented.<br />(or copy and paste the code from the appendix on this step to a new Arduino Sketch)<br /><br /><strong>Option 2: (Adding SERB Routines to your program)</strong><br />Add some simple routines to your pre-existing program (like goForward(), setSpeed(int) etc.). To do this download the routines in the text file (<i>07-(SERB)- Simple Routines Text.txt</i>).<br />1. Copy and paste the preamble portion to the beginning of your program.<br />2. Copy and paste the routine portion to the body of your program.<br />3. Add a call to <i>serbSetup();</i> to your <i>setup()</i> routine.<br /><br /><strong>Option 3: (Creating your own program from scratch)</strong><br />This is not too difficult. All that is required is to familiarize yourself with the Arduino Servo Library. Then the right servo is connected to pin 9, and the left servo to pin 10.<br /><br /><strong>note:</strong> Additional programs will be added here as they are developed; or if you develop something and would like it featured send me a private message and it can be added.<br /><br /><strong>Appendix:</strong> (SERB_Test.pde Code)<br /><br /><pre>/*<br />* Arduino Controlled Servo Robot (SERB) - Test Program<br />* For more details visit: http://www.oomlout.com/serb<br />*<br />* Behaviour: A simple test program which causes the SERB<br />* to turn randomly either left or right for a<br />* random time period between 0.1 and 1 second.<br />* The SERB will then drive forward for a random<br />* time period between 1 and 2 seconds.

First discovered back in 1988 by Nathan Cohen and later published and patented in 1995. A fractal antenna has a few unique attributes as seen in this definition from Wikipedia:<br /><br />"A fractal antenna is an antenna that uses a fractal, self-similar design to maximize the length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic signals within a given total surface area or volume."<br /><br />What exactly does that mean? Well, you need to know what a fractal is. Also from Wikipedia:<br /><br />"A fractal is generally a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,a property called self-similarity."<br /><br />So basically, a fractal is a geometric shape that repeats and appears over and over no matter how far out or how far in you zoom magnification.<br /><br />Source: Wikipedia and <a href="http://patimg2.uspto.gov/.piw?PageNum=6&docid=US007088965">http://patimg2.uspto.gov/.piw?PageNum=6&docid=US007088965</a> Patent number: 7088965]<br /><br />Fractal antennas have been found to be approximately 20% more efficient than normal antennas. Which could be useful. Especially if you want to make your own TV antenna to pick up over the air digital or high definition video, increase your cellular range, wifi range, FM or AM radio reception, and so on. Most cell phones already have built in fractal antennas. If you noticed in the past few years that cell phones no longer have antennas on the outside. That is because they have a internal fractal antenna etched on a circuit board which allows them to get better reception and pick up more frequencies such as bluetooth, cellular, and WIFI all from one antenna at the same time!<br /><br />Wikipedia info:<br /><br />"A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously. Normally standard antennas have to be "cut" for the frequency for which they are to be used and thus the standard antennas only work well at that frequency. This makes the fractal antenna an excellent design for wideband and multiband applications."<br /><br />The trick is to design your fractal antenna to resonate at what ever center frequency you wish to receive. Which means it will look different and be sized different depending on what you want to receive. A little math can be used to figure this out. (Or a online calculator)<br /><br />In my example, I am going to make a simple one but you may want to make a more elaborate one. The more elaborate the better. I will use a spool of 18 Gauge solid core wire to make a antenna as an example but you could go as far as to etch your own circuit boards for aesthetic reasons, to make it smaller, or more elaborate with more resolution and resonance.<br /><br />I am going to use the example of making a TV antenna for digital or high definition reception for over the air broadcasts. It is easier to work with these frequencies and they fall around half a foot to a few feet in length for half wavelengths of the signal. I am also going to base it off a common dipole antenna for simplicity and cheapness of parts for VHF. For UHF you may want to add a director or reflector which will also make it more direction dependent. VHF is direction dependent as well but instead of pointing directly at the TV station like UHF you want VHF rabbit ears (dipole antenna) to be perpendicular to the TV station. But there is a little more design to that. I want to keep this as simple as possible as it is already a very complex subject.<br /><br />Basic supplies (cost me about $15):<br /><br />Mounting surface such as the plastic project enclosure (8"x6"x3"). <a href="http://www.radioshack.com/product/index.jsp?productId=2062285">http://www.radioshack.com/product/index.jsp?productId=2062285</a><br />6 screws. I used steel self tapping sheet metal screws.<br />A impedance matching transformer 300 ohm to 75 ohm. <a href="http://www.radioshack.com/product/index.jsp?productId=2062049">http://www.radioshack.com/product/index.jsp?productId=2062049</a><br />Some 18 gauge solid hook up wire. <a href="http://www.radioshack.com/product/index.jsp?productId=2036274">http://www.radioshack.com/product/index.jsp?productId=2036274</a><br />RG-6 coaxial with terminators (and rubber jacket if mounting outside).<br />Aluminum if using a reflector. The enclosure above came with one.<br />A sharpie marker or equivalent preferably with a fine tip.<br />Two pairs of small needle nose pliers.<br />A ruler of at least 8 inches.<br />A protractor to measure angle.<br />A drill and drill bit that is smaller diameter than your screws.<br />Small wire cutter.<br />Screw driver or screw gun.<br /><br /><strong>NOTE: The bottom of the antenna is to the right of this picture where the transformer sticks out.</strong><br /></div><table align="center"><tbody><tr><td><div id="spot147470" style="padding: 0px;

For windows users, download the following:<br /><a href="http://wiremap.phedhex.com/instructable/wiremap_instructable_windows.zip">http://wiremap.phedhex.com/instructable/wiremap_instructable_windows.zip</a><br /><br />For mac & linux, download the following:<br /><a href="http://wiremap.phedhex.com/instructable/wiremap_instructable_nonwin.zip">http://wiremap.phedhex.com/instructable/wiremap_instructable_nonwin.zip</a><br />Then, go to <a href="http://www.processing.org/">http://www.processing.org</a> and download the program. Processing will allow you to run the programs in the zip.<br /><br />Windows - open calib_64 -> application.windows -> calib_64.exe. If you see a bunch of multicolored lines going across your whole screen, you're good.<br /><br />Other OS - open calib_64.pde with processing.

The diagram below is a bird's eye view of a projector throwing it's light.<br /><br />In regular situations, the projector hits a surface at a given distance. Pretend there is a screen at the line labeled "mapline" that the projector is hitting. Now, take that screen and cut it up into a bunch of vertical strips. By moving some strips closer towards the projector, the projector effectively projects in 3d space.<br /><br />The projector is fed by a computer that has the depths of all the vertical strips memorized.

With less wires, you'll have an easier time constructing and calibrating your project. With more wires, you'll have to be more precise during construction and calibration, but the end result will have a higher resolution.<br /><br />If you're looking to learn about the project, 64 wires should be fine. You'll get a good idea as to how things work, and you'll still get a pretty cool effect with a few of the programs. If you're looking for something more challenging, try 96 or so wires. And if you're into intricate work and are willing to spend a bit of time on this project, try 128.<br /><br />In any case, once you figure out what you want, write down the following on your xl sheet:<br /><br /><i>64 wires</i><br />Available to projectors w/ a horizontal res of 1024, 1152, 1280, or 1920<br />Mapline Length: 32"<br />Map Unit: 1/2"<br />Depth Unit: 1/2"<br />Depth Levels: 40<br /><br /><i>80 wires</i><br />Available to projectors w/ a horizontal res of 800, 1280, or 1920<br />Mapline Length: 35"<br />Map Unit: 7 / 16"<br />Depth Unit: 7 / 16"<br />Depth Levels: 45<br /><br /><i>96 wires</i><br />Available to projectors w/ a horizontal res of 1152, or 1920<br />Mapline Length: 30"<br />Map Unit: 5 / 16"<br />Depth Unit: 5 / 16"<br />Depth Levels: 64<br /><br /><i>100 wires</i><br />Available only if your projector's horizontal res is 800<br />Mapline Length: 31.25"<br />Map Unit: 5 / 16"<br />Depth Unit: 5 / 16"<br />Depth Levels: 64<br /><br /><i>128 wires</i><br />Available to projectors w/ a horizontal res of 1024, 1152, 1280, or 1920<br />Mapline Length: 32"<br />Map Unit: 1/4"<br />Depth Unit: 1/4"<br />Depth Levels: 80<br /><br />How many nuts and bolts do you need? Just take your number of wires and double it!<br /><br />In case you were wondering what these values are: The mapline length is the width of your projection at a given distance. Remember how I explained this in the beginning with the vertical strips? The number of wires is the number of vertical strips, and the map unit is the distance between each vertical strip.<br /><br /><strong>Determining the Depth</strong><br /><br />Here are the two guidelines for figuring out how close your wire field is to your projector.<br /><br />1 - <i>Throw Ratios</i> Notice in the image below: you've got a depthline and a mapline. The length of these lines are the same measurements you used to determine your minimum and maximum throw ratios. The ratio for your plan must fall within your projector's throw ratio.<br /><br />2 - <i>Closest zoom</i> The center of your wire field must be further than your closest zoom measurement.<br /><br />So, given that your mapline is a fixed width, find a depth that works for both your throw ratio <i>and</i> your focal distance.<br /><br /><strong>Example please!</strong><br /><br />So, for my construction, I went with 128. My mapline length is 32".<br /><br />My widest ratio is 1:2. With a fixed mapline of 32", the depth for this throw ratio would be:<br /><br />depth = x<br />1:2 = 32": x corresponding ratios<br />1 * x = 32" * 2 cross mutiply<br />x = 64"<br /><br />My tightest ratio is 27:72. <br /><br />depth = z<br />27 : 72 = 32" : z corresponding ratios<br />27 * z = 32" * 72 cross multiply<br />z = (72 * 32") / 27 divide<br />z = 85.333<br /><br />To fit my projector's throw ratio, my depth must be between 64" and 85"<br /><br /><strong>Closest zoom</strong><br /><br />My projector's closest zoom distance is 45". The center of the wire field must be greater than 45" away from my projector. Because the wire field is 20" deep (as is everybody's), the center of the wire field is 10" shorter than the depth. So, as long as my map line is greater than 55" out (45" + 10"), then I'll be okay.<br /><br />For my case, I can just disregard this because my throw ratios are more limiting than that anyhow.<br /><br />I ended up settling on a 68" depth from my projector to the mapline. This gives me a 4 inch margin of error (I'd always give myself at least a 2" margin of error, just for good measure).<br /><br /></div><table align="center"><tbody><tr><td><div id="spot145693" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/FEE/D53Q/FQMXFCTW/FEED53QFQMXFCTW.MEDIUM.gif" galleryimg="NO" alt="basic-plan.gif" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">286x400 : FEED53QFQMXFCTW (0)</div><a href="http://www.instructables.com/file/FEED53QFQMXFCTW/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot145693 = new ImageSpot( 'spot145693', { loadID: 'FEED53QFQMXFCTW', loadIMG: '/files/deriv/FEE/D53Q/FQMXFCTW/FEED53QFQMXFCTW.MEDIUM.gif', altString: 'basic-plan.gif', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot145693, {"imageID":"FEED53QFQMXFCTW","name":"basic-plan.gif","imageURL":"/files/deriv/FEE/D53Q/FQMXFCTW/FEED53QFQMXFCTW.MEDIUM.gif","showURL":"/file/FEED53QFQMXFCTW/","description":null,"length":4362,"width":286,"height":400} ); InstructJS.cachedRefs.spotspot145693=spotspot145693; });</script> </td></tr></tbody></table></div><div style="margin-bottom: 15px;"><h2><a href="http://www.instructables.com/id/SD921NRFQR1O682/" name="step5"><span class="stepLabel" style="padding-right: 5px;">step 5</span><span class="stepTitle">Determining the Depth</span></a></h2><div class="txt">The first step to plotting out your wiremap is to figure out your project's depth.

This is your depth line. Next, draw a line along a long edge, 2 inches away from the edge (use another piece of foam core as a straight edge). This is your mapline.<br /><br />(image 2)<br />Where the mapline and the depth line is is the center of your mapline. Draw tick marks around the center of your mapline, coming out in either direction. Each tick mark is a "map unit" length away from the next. Half the tick marks on one side of the depth line, half on the other. Note - the depthline is half way between two mapline ticks.<br /><br />Once you get your tick marks down, the distance between your left-most tick mark and your right-most tick mark should be equal to your mapline length minus one map unit length.<br /><br />(image 3)<br />Starting from your left-most tick mark and your right-most tick mark, draw two lines parallel to the depth line. These are your depth level guides.<br /><br />Along both depth level guide, draw tick marks. Each tick mark is a "depth unit" length away from the next, with the mapline being 0. Draw as many ticks as you have depth levels.<br /><br />(image 4)<br />Once you have both depth level guides ticked out, connect them. That is, draw a series of lines parallel to your mapline. Once again, use another piece of foam core as a straight edge.<br /><br />(image 5)<br />The last step in plotting your layout is marking everything:<br /><br />Mark the mapline tick marks from 0 to wires - 1 (for me, I numbered from 0 to 127). 0 is on the left side looking towards the projector.<br /><br />Mark the depth levels from 0 to however many depth levels you have. The mapline is depth level 0, and the next parallel line is level 1, and so on...<br /><br />Great!

Tape a piece of plywood at that spot.<br /><br />Draw the depth line onto your plywood. A good way to get the straight edge here is to tape a piece of string to the center of the mapline and pull it taught. When it matches the depthline on the foam core, mark up your plywood and draw it out.<br /><br />Then, measure from your mapline to draw the intersect - where your projector sits.<br /><br />Take some thread and tie it off on a hex nut. Drill a screw (or nail a hammer) through the hex nut into the intersection on the plywood.<br /><br />Now you have a straight edge long enough to follow your path of light!<br /></div><table align="center"><tbody><tr><td><div id="spot145696" style="padding: 0px;

Open and print the data file that ends with the wire number you chose.<br /><br />The files have the following format:<br /><br />map[0] = 43;<br />map[1] = 15;<br /><br />This means that tick 0 on the mapline has a depth of 43, and tick 1 on the mapline has a depth of 15.<br /><br />Take the string that's tied to the hex nut and pull it tight to tick 0 on the mapline. Then, with a pencil, mark out where the string intersects depth level 43. Move the string to tick mark 1, and mark where the string intersects depth level 15.<br /><br />You might also want to circle each of these tick marks, just so that they're more visible to you.<br /><br />Once you're done with this step, you can untape the foam core from the ground (but keep them taped together). Use some clamps to clamp all three together, clamping one on each edge.<br /><br />Now, use a needle scribe (or just your needles) to puncture holes into your foam core.

You'll want to orient this the correct way - the mapline on the opposite side of the projector. Also, the faceplate with the tick marks on it should be facing the floor.<br /><br />(image 3)<br /><br />Now, use your needle to thread all your threads through all three plates.<br /><br />When you're finished threading, we need to separate the bottom plate out. Unclamp and untape the plates from one another. Use those four clamps to clamp further down on the dowels to support the bottom plate.

Use your level to make sure the plates are level. You'll also want your strings to go straight up and down. One good way to see if your strings go straight up and down is to tie a nut to some extra string and to let it hang next to a thread in your wiremap (image 5).

If you're precisely where you need to be, you'll see all your wires equidistant from one another. Anywhere else, and they'll overlap. Find that hot spot, and put your projector there.<br /><br />Fire up your projector and set your computer to match it's native resolution. Get to those files you downloaded and run the calib program with your wire count attached to the end of it.<br /><br />Once you get that running, you should see a series of vertical strips of light. This program has your wire positions memorized, and it shines a color of light depending on how distant each wire is. The wires that are closest are red, the ones that are furthest are blue, and the ones in between are green.<br /><br />The first thing you'll want to do is to drop a piece of paper about half way through your strings (maybe even a tad bit closer) to focus your image on it (image 3).<br /><br />Once you're focused, your wires will probably look something like image 4 below - with each wire having bands of light and darkness. This is because your projector is out of tilt. Fix this by tilting your projector right and left.<br /><br />Then, you'll probably that one side is out of tilt while the other side is lining up. This is due to the projector being out of tilt in the forward and backward dimension. This is called a keystone distortion, and it can be fixed by tilting your projector up and down. If your image is too fat on the bottom, you need to tilt your projector upwards. If it's too fat on top, tilt it downwards. Use your shims (image 5).<br /><br />Now, fix the zoom on your projector. You'll want the left side of the image to just be hitting the left-most string, and the right side to be hitting the right-most string.<br /><br />Try to find that hot spot - & you'll know when you hit it. Keep an eye out for when all the strings closest to you turn red. If you're having trouble, temporarily block the light coming from your projector and pull out your camcorder and try recentering the projector. Play with zoom and projector location. Keep playing with your zoom and location, and you'll find it soon. (image 6)<br /><br />**tip - the projector's focal point is usually 2 - 3 inches behind the lens.<br />**tip - also remember that you can make micro adjustments to the foam core - this is very useful especially in the end of the calibration process.<br /><br />Once you get partially calibrated, it's just lots of small fudging from there. Go up to the wire field and push on a thread in both directions to see which way the light needs to go (images 7 and 8). Take notes, and make a quick diagram:<br /><br />If the strings need to be pushed this way to resolve:<br />_ _ _ _ _ _ _ _ _ _<br />\. .-->. . . . . . . .<--. . /<br />.\. . . . . . . . . . . . . . . /<br />. \. . . . . . . . . . . . . . /<br />. .\_ _ _ _ _ _ _ _/<br /><br />... then the light needs to go this way:<br /><br />_ _ _ _ _ _ _ _ _ _<br />\. .<--. . . . . . . .-->. . /<br />.\. . . . . . . . . . . . . . . /<br />. \. . . . . . . . . . . . . . /<br />. .\_ _ _ _ _ _ _ _/<br /><br />If the light needs to get wider in the back but is perfect in the front, this means you need to move your projector forward and widen the focus.<br /><br />Keep making these micro adjustments. This is a very time consuming process, but it's well worth is and pretty much the final step.<br /><br />And lastly, I've found from experience that I'll get to this point and realize that everything is perfectly aligned except for one or two threads in the middle. This is because their holes are just off center. If you find any of these, just cut those strings, remove them, and move on.<br /><br />When you're all done, it should look like image 9, below..<br /></div><table align="center"><tbody><tr><td><div id="spot145701" style="padding: 0px; position: relative;"><div style="border: 0px solid blue;"><img src="http://www.instructables.com/files/deriv/F6I/JC2N/FQR1O5BH/F6IJC2NFQR1O5BH.MEDIUM.jpg" galleryimg="NO" alt="calib1.jpg" title="" /></div><div style="border: 1px solid rgb(170, 170, 170); padding: 20px; white-space: nowrap; display: none;" class="formInstructionsText">image not found</div><div style="position: absolute; width: 100%; top: 40%; left: 0px; visibility: hidden;"><center><img src="http://www.instructables.com/static/img/loading2.gif" alt="loading..." /></center></div><div style="border: 1px solid black; padding: 2px; background: rgb(255, 255, 255) none repeat scroll 0% 0%; position: absolute; bottom: 5px; left: 5px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; visibility: hidden;">500x375 : F6IJC2NFQR1O5BH (0)</div><a href="http://www.instructables.com/file/F6IJC2NFQR1O5BH/" class="withBG" style="padding: 0px 5px 0px 6px; position: absolute; top: 5px; left: 5px; visibility: visible; font-style: italic; z-index: 2500;">i</a></div> <script language="javascript" type="text/JavaScript"> InstructJS.load(['instruct','imagespot'], function () {var spotspot145701 = new ImageSpot( 'spot145701', { loadID: 'F6IJC2NFQR1O5BH', loadIMG: '/files/deriv/F6I/JC2N/FQR1O5BH/F6IJC2NFQR1O5BH.MEDIUM.jpg', altString: 'calib1.jpg', editimagedata: 'false', imageDataEditorPlace: '', showInfo: true, size: 'MEDIUM' } ); new ImageInfo( spotspot145701, {"imageID":"F6IJC2NFQR1O5BH","name":"calib1.jpg","imageURL":"/files/deriv/F6I/JC2N/FQR1O5BH/F6IJC2NFQR1O5BH.MEDIUM.jpg","showURL":"/file/F6IJC2NFQR1O5BH/","description":null,"length":216074,"width":1280,"height":960} ); new ImageInfo( spotspot145701, {"imageID":"FBOKDU5FQR1O5BG","name":"calib2.jpg","imageURL":"/files/deriv/FBO/KDU5/FQR1O5BG/FBOKDU5FQR1O5BG.MEDIUM.jpg","showURL":"/file/FBOKDU5FQR1O5BG/","description":null,"length":211676,"width":1280,"height":960} ); new ImageInfo( spotspot145701, {"imageID":"FENP6YTFQR1O5DY","name":"calib8.jpg","imageURL":"/files/deriv/FEN/P6YT/FQR1O5DY/FENP6YTFQR1O5DY.MEDIUM.jpg","showURL":"/file/FENP6YTFQR1O5DY/","description":null,"length":194684,"width":1280,"height":960} ); new ImageInfo( spotspot145701, {"imageID":"FNY174MFQR1O5E3","name":"calib3.jpg","imageURL":"/files/deriv/FNY/174M/FQR1O5E3/FNY174MFQR1O5E3.MEDIUM.jpg","showURL":"/file/FNY174MFQR1O5E3/","description":null,"length":303966,"width":1280,"height":960} ); new ImageInfo( spotspot145701, {"imageID":"FGW3XHZFQR1O5DX","name":"calib9.jpg","imageURL":"/files/deriv/FGW/3XHZ/FQR1O5DX/FGW3XHZFQR1O5DX.MEDIUM.jpg","showURL":"/file/FGW3XHZFQR1O5DX/","description":null,"length":190827,"width":960,"height":1280} ); new ImageInfo( spotspot145701, {"imageID":"F25NAA6FQR1O5E2","name":"calib4.jpg","imageURL":"/files/deriv/F25/NAA6/FQR1O5E2/F25NAA6FQR1O5E2.MEDIUM.jpg","showURL":"/file/F25NAA6FQR1O5E2/","description":null,"length":298984,"width":1280,"height":960,"notes":[{"noteID":"NY5HAMYFQR1WYAF","author":"M8QRRA8FQMXES0R","screenName":"phedhex","text":"Keep an eye out for this section to turn red","top":0.6666666666666666,"left":0.084,"width":0.564,"height":0.30133333333333334,"addedDate":1234116199045,"modifiedDate":1234116199045}]} ); new ImageInfo( spotspot145701, {"imageID":"FKPRVTEFQR1O5E1","name":"calib5.jpg","imageURL":"/files/deriv/FKP/RVTE/FQR1O5E1/FKPRVTEFQR1O5E1.MEDIUM.jpg","showURL":"/file/FKPRVTEFQR1O5E1/","description":null,"length":200784,"width":1280,"height":960} ); new ImageInfo( spotspot145701, {"imageID":"FV6XHH8FQR1O5E0","name":"calib6.jpg","imageURL":"/files/deriv/FV6/XHH8/FQR1O5E0/FV6XHH8FQR1O5E0.MEDIUM.jpg","showURL":"/file/FV6XHH8FQR1O5E0/","description":null,"length":198675,"width":1280,"height":960} ); new ImageInfo( spotspot145701, {"imageID":"FGQPXLHFQR1O5DZ","name":"calib7.jpg","imageURL":"/files/deriv/FGQ/PXLH/FQR1O5DZ/FGQPXLHFQR1O5DZ.MEDIUM.jpg","showURL":"/file/FGQPXLHFQR1O5DZ/","description":null,"length":285489,"width":1280,"height":960,"notes":[{"noteID":"NL0CYIEFQR1WYAE","author":"M8QRRA8FQMXES0R","screenName":"phedhex","text":"from side view - see?
