Older versions: v0.3 – 9v
bugfix:
IC 2 (CD4053) has a small bug . Pin 6, 9 and 10 should have been connected to GND, but are not.
Use a snipped off piece of resistor leg to connect these pins to GND. Pin 7 and 8 are GND.
So: bend the metal leg like shown in the above picture and solder it. (on the backside of the IC. make sure you connect the right pins!)
The bug is that , when powered by an adapter (9v or 12v), after a while the sound gets weird. This happens sometimes, but not always. This made the bug hard to trace 🙂
