AVR and MOSFET H Bridge and PWM
It is better to learn what is deadzone on small currents. A condition is possible when one side is not yet closed and another is being opened. A shortcircuit happens. 60 amps...

Vision System with AVR
Yeah, but would they be able to escape the "embedded lawnmower"? :)

PonyProg Problem
Try changing that "Avr ISP I/O" to whichever is the different option there. LPT1 must become available then.

making the upper nibble of a byte = 0
I once had a problem with gcc and uint32_t variables too, i don't trust them since. But here we have uint8_t I believe? The question is also how did the OP observe the phenomenon...

making the upper nibble of a byte = 0
I tried with gcc (egcs-2.91.66) and it works fine here, either way. Which compiler you're using? The result you mention sounds as if the compiler in fact did: d1 &= 4 | 2 | 1;...

I don't know the exact content of your Makefile (note the case, it's not important under windows, but this is how this file is usually called), but it's obvious that it doesn't...

My GameToy project
Cool stuff! I liked the music sample. You need to add more waveforms to get the cheesy vintage arcade sounds.

ISP DIY programmer using 74HC244 - function of Vcc diode
If you power the programmer from the AVR side, you can't have more volts than AVR has on the input lines, even if LPT port has larger voltage swing. Even if you had, AVR's...
