Main PCB assembly 1. Solder the diode and all resistors 2. Solder all three IC sockets 3. Solder the non elecrolytic capacitors 4. Solder the 78L05 and BC547s– watch the polarities! 5. Solder the box power header. Make sure the notch lines up with the screenprint legend.

Control PCB assembly 1. Place the PCB on a flat surface. Place the 2 tactile switches into their solder pad. Do not push them all the way through, they should sit proud of the PCB (see photo), their legs should not protrude through the other side.

1. There is nothing to calibrate on this module – cool! 2. Go forth and divide. Troubleshooting Not all DIY builds work first time. The vast majority of build issues are down to soldering inconsistencies. This is far more likely than a bad IC, for example. The first step of successful troubleshooting should always be to reflow all soldering to eliminate any dry joints (bad connections) or solder bridges (short circuits).
