Gherkin Of The Week #3

Aluminum bottom Gherkin

Took a piece of 1/16th thick aluminum and punched holes in it that match the switch positions. I used one of those cheap metal punches from Amazon. I used a spare PCB as a template to position the holes. The holes for the M2 screws I drilled with my Vanda-Lay drill press.

The black PCB is one of the ones I made at JLCPCB. It has no silkscreen layer and is all black on both sides. I also installed the diodes and resistors on the bottom of the PCB.

 Gateron clear switches with green 2x3x4 LEDs installed inside them.

 M2 spacers and screws.

 Aluminum plate with punched holes. The plate was a little short.
