Dcf 77 Receiver & atmega8535
Sampling and decoding the LF timesignal is quite possible, but I've not tried specifically on the AVR. It can be done though, but I'm going to stay out of this until the trolling...

Dcf 77 Receiver & atmega8535
You will need a decent filter network after the antenna, and some sort of amplification. The DCF signal itself is relatively weak, and the Q factor of just the antenna itself...

generating 74kHz square wave using atmega8535
I suppose showing us your code and pointing out what you think isn't working is out of the question?

comparing char with int data type
This smells like an assignment. Consider the values possible for uint8_t. What's the smallest and largest possible value? What then is the value of multiplying 25 by 100?

Audio over LAN
This is probably going horribly offtopic, but try the Stellaris LM3S9B9X series.

How to solder a capacitor bank without thermal pad
If you are only building one, it might be feasible to preheat the board first, with appropriate heatsinking for the caps.

Best Pre-sensitive photoetch pcb maker
Kinsten has been pretty reliable (as in zero scratches on the photoresist) for me. I expose with a normal tablelamp.

Angle grinders & power tools in general
Hmm, recently just saw a drill that had a multiple-tapped coil. with the speed control permitting the current to flow to either one of those taps. That sounds like a workable but...

Angle grinders & power tools in general
Some of the angle grinders are pretty primitive, with a rheostat for "speed" (really power) control.

delays in C
You're looking at something called "Dead Code Elimination". Several approaches to this, and most result in you having to understand precisely what the complier considers as "dead".

What language, which bit do you need help on? Also, what arch?
