Capable of generating like any waveform in 8 bit

Quick and dirty. As soon as it was ready, it got hooked up with another function generator and pluged into my stereo, then hours passed, me playing with a simple oscillator :)

The pcb:

It became somewhat compact. The fat ic is the AVR Atmega 32.
It got a button to switch waveforms and a poti at one adc to set the frequency.

One resistor network as dac (digital to analog converter):
