The Duke Whiskers Melody Generator

This is just a slacker melody generator in a awesome case. I found the schematic for this in an intro to lunetta document. Here is the link:

Its a great read. For some reason everytime I've tried to build one of these since they don't work. Fortunately, this one did. Unfortunately, I can't find the video of it working.

The three switches turn the three oscillators on and off respectively. The three knobs on the right control the rate of those oscillators. The knob on the left controls the clock speed and the switch below is the power switch.

Here is the schematic I used for this. I used a 40106 for the A,B, & C inputs and for the clock input.
