No Title, important
Folks, I'm looking for design ideas please! i need the following:
* HHO (water car thingy)
* Spinning wheels/coils (maybe magnets)
* Driving LEDs chasers (in parallel, i can save resistors), maybe KnightRider
* Controlling speed of DC motor (tiny) and breaking
* Building clocks with TTL devices (must be 7490, I have those)
* And circuits for building audio amps, LM386 or uA709 please!
These all seem to be good ideas to me as I'm looking for something original, so please, if u can respind really soon, it would be really great. I need complete schemas, no, schematics? All by 20NOV08, as it's due, er, I just need them soon, please!!
Looking forward to your kind replies really soon! You guys R great.
