My father has been a lifelong Ham Radio Operator with a fondness for almost anything with a panel meter. After seeing the “Trinket Powered Analog Meter Clock” by Mike Barela on the Adafruit website I knew I had to create one to give to my Dad for his 80th birthday. Here is the result.

Update:

Added missing source files hour-meter.mtr and minute-meter.mtr for MeterBasic custom meter scales.

Update 2:

Created new meter scales. PDF and Inkscape SVG source files provided in case you want personalize your clock.

Update 3:

Created a new custom PCB, matching rear cover and an assembly video.
Updates and details to follow.

0.2mm layers

All parts print without support. I printed mine in PLA with a 0.2mm layer height using 3 top, bottom and perimeter shells with 20% infill.

See the included PDF file for assembly instructions and the 2 included zip files for the Arduino sketches that run the clock.
