I’m developing a new design of GPS speedo. I haven’t actually made anything yet for this particular design (awaiting access to 3D printer post lockdown). I’ve made various other GPS speedos.
I’ve done the design of the housing. Some shots of the Tinkercad design:
The apertures are for the various boards and other bits. I’ll be using a GPS module from Core Electronics that works well, an Arduino Pro Mini processor and a 4 digit 7 segment LED display for the speed. There will be a piezo buzzer at the rear for overspeed alert and a header for plugging in an HC-05 Bluetooth module.
It should be a neat device and I hope others make it too. Will post updates as I progress.
