Uses a simple USB-C trigger board to power banana jack terminals. Probably compatible with other banana jack terminals with slight modifications. I've included some photos of the assembly process. The trigger board used is only compatible with QC2.0 and QC3.0. It will only output 5V with laptop chargers that only support QC4.0.
mk2 changes:
- moved the banana jacks lower in the device
- added cover to protect wiring
- improved the PCB retaining nubs
- Added pocket to make assembly easier
- Added bushing to keep power wires insulated
BOM:
- m3 threaded inserts (4mm length)
- m3 socket headed shoulder bolt (10mm length)
- USB-C trigger board
- 4mm banana jack terminals
- 18 gauge stranded wire
