Dumbl’Ador v1.0 Building sequence Soldering this board can be very complicated for some people since the solder pads are very close together. Use a magnifying glass to make the job easier. Do not blow on your solder in an attempt to cool it down. That will possibly result in a bad join that might corrode! If you want to experiment with other diodes or transistors then you could socket them instead of soldering them to the board. -

Dumbl’Ador v1.0 Off board wiring The biggest challenge of this build is to get all the offboard wiring correct and fit it in a box. Take your time measuring and testing before you start fitting everything in the box. P1-P4 are PCB mounted potentiometers (Alpha). The rectangle pad marks pin 1 of a potentiometer. The images below show how you can recognize which pin is which on a potentiometer. -
