Solder in the IC-sockets first: + - make sure the small notch in the socket aligns with the notch on the silkscreen graphics + - solder two diagonal corner pins first + - once everything is flush solder the rest of the pins +2. Solder the ceramic capacitors (next to the IC-sockets) +3. Solder the red film capacitors +4. Solder the 100k resistors + - bend one leg around, so it fits the vertical footprint +5. Solder the IDC pins for the jumpers +6. Solder the TRS jack +7. Prepare 17 short cables, for each: + - cut the cable to length (depends on the case used) + - strip the isolation off the wire at both ends, drill the exposed copper strands + - tin both sides of the cables +8. Solder the cables to the controls: + - 3 for volume potentiometer + - 2 for timbre potentiometer + - 2 for drone switch + - 2 for fire button (do not solder this one yet!) + - 6 for frequency potentiometer + - 2 for power switch (if needed) +9. Solder the connectors to the PCB in the appropriate places (see graphic above) +10. Drill holes in the case (for potentiometers, switches etc) and put all the controls in +11. Solder the fire button +12. Test + ## Errata (revision 0.9) There is a mistake with the output power switching in revision `0.9` – gladly this is easily fixed, by drilling away a pad and bridging a connection:
