OT: Simple shaft encoder for modified RC servos
Not a bad idea. I imagine you could key off other gears to get a higher resolution if you needed it, but that would depend on how tiny your optical components are.

ATmega16 and servo
1.5ms should be right in the middle. I know how many things can goof up the calculation, that's why I suggested you measure it. I wonder if you have a "positive pulse" servo and...

Communication over power line (12V-DC)
A common model rail control system (DCC) encodes the singnal in polarity reversals and just uses a diode bridge and capacitor to derive the receiver's power.

Is the ATtiny13's operating current *that* low?
In that case, look for a 70k or so resistor and a zener diode.

Sounds like your pulse is too long or short. Try measuring your pulse width.

JTAG programming Mega32
Last time I had a chip that refused every time I tried to program it... It wasn't getting VCC. The chip isn't powered by the ISP, the ISP is powered by the system you're...

Your master then polls the slaves to see if they have something to say? Hmm, this brings to mind a frightening scene :o

You like want us to write your program? I can be hired...

But wouldn't that cause the suppressor to draw lots of current?

regarding c and assembly coding for avr
To tell you the truth, I just use whatever tool I'm most familiar with that will get the job done.

Communication over power line (12V-DC)
I was thinking of using a big transistor and resistor on the transmitter to pull some extra current, then detect the current at the power supply end. Of course, if you need to...
