First off, if you choose to go all the way and make this use the flyback circuit like I did, you need to understand you are dealing with VERY high voltage, and even though it is technicaly static, under the right circumstances, even static can kill!, So please have at least a basic understanding of working with high voltage, or get the assitance of someone that does! And please, dont electrify any pets, neighbors, siblings, parents, bosses, ect,ect, no matter how tempting it might be =) And seriously, DON'T touch ever touch the electrode, the aluminum plate oranything inside the monitor or TV that you dont recognize!!
Step 1: Getting your parts!
However if you do need to scavenge for parts, places like, Good will, SOS, salvation army, are great places to look, usually you can get printers, and scanners for 3 or 4 dollars U.S., Also, hit up relatives!
You will need 1 flat bed scanner.
1 old printer
1 old remote control car, Has to be full function.
1 old wall transformer with a 5 volt DC output, and you will need 2 monopolar capacitors, I used polyester film capacitors, radioshack sells them, for only 2 or 3 dollors. (they MUST be monopolar)
A few small pieces of metal and plexi glass.
2 Long springs, mine came from 2 old flexible automotice magnetic retriving tools.
2 servos, I used 2 futaba brand, model S3003, 44.4/56.9 oz, torque, I don't wouldent using anything smaller. Got mine from hobby town, 10.99 u.s.
A piece of plywood, or press board, a 2 foot square should be fine, I already had some, but it would be pretty cheap at menards, they sell it in 2 foot square's for about 3 dollars U.S.
You will need alot of assorted screwdrivers, including some star heads, and possibly some safety screw tips, an exacto knife(s), a soldering iron, and some heat shrink tubing, red and black wire, stranded or solid.
You will need a hot glue gun, and LOTS of glue sticks, (again, this isnt meant to be as presice as a CNC machine)
