FYI NTSC changed it to 15.73426kHz for color, not sure why Wikipedia rounded up the color burst 3.58MHz from 3.574595MHz its only significant because it was formulated so the harmonics didn't screw with anything else and they could add color with getting rid of all the black and white tvs.

I think MC chris has it right http://mcchris.com/ http://en.wikipedia.org/wiki/Mc_chris

how is this different from an actual MAFIA? this isn't even like the difference from loan sharks charging 20% and going to jail for extortion and visa doing the same thing and being a profitable business... This is an actual threat to a learning instituion.

use a PIC microcontroller. the nicest 8 bit microcontroller costs $4 and a programmer costs ~$40 (the software is free), have them wire up a circuit by example on a breadboard and then have buttons and switches correspond to leds(20mA sink/source, so don't need a output transistor). you could get to a point where you can run a dc motor in place of a led. teach them simple assembly and how to use it instead of a proprietary langauge they can't use at home with out a lot of money. Teach them something fun they don't have to be in front of a computer to play with. Assembly teaches good logic concepts that make every other language cake.

Where is the schematic? What is the 8 pin DIP in the socket? i'd suppose it would be a PIC microcontroller or something, if it was then where is the code? But idk if it is just an OPAMP. Does it actually pulse codes or does it do a random oscillation of the IRs until something shuts off?
