2021-12-04 (Sa) EWC_Panel MIDI and power ports

The spacers between the lunch box and micro USB PCB finished printing. I made them the same width as the cover, so they were too snug. I sanded down the edges until they fit. The printing process also deformed the holes at the back, so I drilled them out with a 3mm bit. I also added a layer of fingernail polish to the letters "Micro USB" to make them stand out better, and they looked great.

I marked out the three MIDI port locations and the USB plug. I put down a layer of painters' tape and marked the holes with a pencil, but they were crooked, so I made a straight line and remarked them with a Sharpie until they looked professional. The MIDI port mounting holes were 1/8" so an M3 bolt would have a little room, and the large hole in the middle needed a stepped bit. I cleaned up my drill holes with a cylindrical carbide bit in a Dremel.

I soldered long wires to my ports and power, then shrink-wrapped the terminations. I thought I had some short cap-head bolts, like the ones I used on the MIDI-TRS adapter, but I had to use pan-head bolts.
