    Now was that so hard?

    pwm to control a dc motor

    I thought we already went through this? If you need a load to see 3V and you are using PWM then you change the duty cycle. But you also need to figure in the voltage drop of the transistor and emitter resistor(if using one). Voltage is what changes the speed of the motor. I don't know why you...

    Led Suit (arduino)

    It regulates whatever voltage you start out with to 3.3V so you can power the matchport it may even provide the arduino with its power as well, but the page does not say that. The arduino might have its own VR on-board.

    Woo-Woo Energy loss In a circuit?

    This is one of those times I hope your not planning on holding your breath, because you won't last long.

    I just had a vision of the future of TV.

    Just giving you some feedback from a consumers perspective. It seems clunky, like glasses for 3D. Can you imagine all the work to make such a system feasible? Would be better in a group atmosphere, but I am afraid they have already done this. Walt disney beat you to it by about 10 years.

    Learning Electronics as a kid......

    Well I never went to school for electronics training. Wish I had though, because as a kid my grandfather and grandmother where the ones who really got me interested in mechanical things. My love of electronics didn't come in till I was a little older. Computers where my fascination from about 16...

    I'll probably die before I wear a set of glasses to watch a 3D movie!

    Woo-Woo Energy loss In a circuit?

    Oh come now, it would only require a machine that was physically invisible to the known world to have perpetual motion. In fact maybe there is one in your basement, you just can't see it yet! ever!?!?! :D

    Need some creativity help...only 1 pin left

    @ 1 AM this made me laugh, now I can go to bed with a smile on my face. Thanks

    How to make AC lights flash

    I don't know of any single IC, but a flip-flop and 4060 would handle the job. Depending on the current needed for the lights a transistor might be applicable on the output of the 4060

    current division in circuit

    answer laplace's question, there is zero current through R1 so there is no voltage drop. The reason why was posted by steve in the post previous to yours.

    What is this component? What does it do?

    and peace! :D

    Kernel or Off the shelf OS?

    I think NetBSD has the most diversified platform of compatible hardware. http://www.netbsd.org/ports/ edit: you'll also notice that it has a business-friendly license. Which should put your mind at ease.

    Supply power for electronic circuits

    This is one of the easiest ways to get a power supply with short circuit protection. You can pull cheap 350W atx power supplies from old computers. A computer repair shop might have one (used pulled from a dead PC) they would sell you for little of nothing.

    pwm to control a dc motor

    Yes, that makes perfect sense and .1 Ohm resistor wouldn't effect the rest of the circuit that much. Thanks for the explaining that, learned something new today.

    pwm to control a dc motor

    What? I guess I need a better explanation because I don't get it as usual.
