P.S If you attempt this I am not responsible for any damages to your self or any of your property. THIS 'IBLE WILL INVOLVE HIGH ELECTRICTY, HOT MATERIALS, AND SEVERE MENTAL STRESS, ok maybe not the last one, but it is very dangerous if you attempt it without prior knowledge of electricity.
Step 1: Gather Materials
1. Solder and soldering iron.
2. Hotglue and a hotglue gun.
3. leds of your choice, the color and count is up to you, but ordeing in 1000's is the cheapest, ebay is the best source.
4. A high voltage power supply, i.e. Disposable camera, if you visit your local drug store they will most likely give you used ones for free.
5. Peg board, homedepot is very good for this a 24 x 48 sheet is $6.
6. IR LEDs, order a certain quantity depending on how big you want you table to be. 4 per 12 x 12 square is usually good.
7. IR sensors, here is a link to digikey they have the best prices. http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=475-1081-ND We will discuss this later.
1. Electric tester capable of 300 volts.
2. A TIP31 Transistor.
3. A speaker set.
4. A heaphone splitter. i.e. 1 male to 2 female headphone plugs.
Step 2: Board Assembly
Ok now you have the daunting task of soldering 1000+ LEDs. So heres how to start, gather your blue and IR LEDs, make sure to keep them seperate, now take each one and bend the leads at a 90 degree angle to the base then bend them upward halfway to the end of the lead as shown. You can do this ahead of time or while your building. After that lay out your battle strategy on the back of the board, you want to make designs that fit together having about 90 LEDs per segment. Or you can do some math to figure out how many you could run off 300~314v depending on how much each draws. Simply divide 300 by the voltage of each LED, then its time to pillage the village. (Also to keep this simple and cheap I won't use resistors for them, although if you have the time it is highly recommended if you google resistor calculator you can try to figure out how big the resistor needs to be I never got the hang of how to do that). So with running 90 per segment they are quite bright, almost hard to look at. Also this board will be run in series so lay your LEDs into place having the positive lead start (usually the longer one) then have the positive lead of the next LED connect to the negative on the previous LED, as for connecting the rows there is an example in the pictures. (Google will give you a better picture of whats going on just search "LEDs in series.") Do this usually a few rows at a time then glue them, while the glue is soft flip it up and try to straiten any ones that have drifted off center, this is why you only do a few at a time it gives you time to move them.
Step 3: Wiring the LEDs.
For the IR lights you want to drill seperate holes in the board to put them through, then just wire them in parallel to a neighboring LED I didn't get to do this because the IR LEDs didn't show up in time.
Step 4: Wiring the Sensors
Step 5: Powering Up.
Step 6: Wrap Up.
Also instead of a second part I've decided to do a whole new instructables so here is a link to that one as well.
Please feel free to express your thoughts and opinions freely here or at the beginning. Happy instructable-ing, everyone!
Also the main reason for this instructable is for the Epilog Laser challenge I would love to be able to manufacture parts to create more 'ibles and other great projects, or maybe even market some of my other ideas.
