This is the final version of my Arduino controlled gear position gauge. I've refined the design over the last couple of years to a point that I was happy to commit to having a printed circuit board manufactured.
I designed the PCB using Diptrace and then had it made by OSH Park in the USA. Turnaround times are about 3-4 weeks and costs were very reasonable at £7 for three boards.
Next job was soldering all the components onto the board.
Everything soldered and fitted into the carbon centre binnacle.
Creating the gauge
The gauge was made by stripping the internals out of a classic mini gauge leaving the casing, glass and chrome bezel.
Next up I designing a mount and 3D printed it.
The glass was tinted using car window tinting film so the OLED isn't visible until it's turned on.
