I would like to present my Atmel programmer with some extra features:
1) First of all, it's USBAsp (mainly on the bottom side of the PCB).
2) On the right side - digital counter with leds connected to different freq devision ratios (up to 2^32), max counting freq tested ~100Mhz.
3) Bottom-right & near middle: 2x square wave generators with jumper-selectable presets: Low freq - 2Hz - 1.5Mhz, high freq - 4kHz - 80Mhz.
4) Bottom-left part: power supply which can give you at the same time:
4.1 filtered 5V from USB and/or 5v supply.
4.2 3.3V
4.3 1.25/1.5/1.8/2.5v - jumper selectable.
Also, you may see hardware fixes of my dump mistakes
In fact, this is the first PCB I designed
