    Thanks for the suggestion. I don't think it should be too much of an issue heat wise but I'll have to see through testing. I don't expect the whole device to even use 1A to be honest. An IMU would be pretty awesome to add, I'll have to grab some components to test that out. At this point I would probably need to add in a toggle button to switch between modes.

    Yeah, it'll probably be okay as long as ambient temp isn't too high. Might consider a heat sink tho.

    I've used a BNO055 IMU in the past, it works good with arduino. Its a pain in the behind with out the arduino library though, I did it with straight C and spent most of my time crying into my coffee :laughing:

    Thanks for the suggestion. Definitely something I will add later, a little bit of a stretch for this first version but I'm definitely looking to add it when I can.

    I think at this point I am gonna look to replace the clock in my truck with this OLED. So I'll probably be adding a time keeping unit in there so I can still have a clock function on each screen.

    Made some progress and finally got the initial connection for OBDII setup. Anyone with an ELM327 or similar bluetooth module would be able to connect.IMG_20200628_160603.jpg

    Gonna start working on some nice graphics for the different variables from the truck. There will be a switch to change modes and settings in the final version, for now a lot is hard coded while I develop. Still working on mocking up a design for the module to fit in place of the OEM clock, nothing worth showing yet. My initial PCB layout is a little bit too large so I need to redesign the board. It's a little ugly at the moment but it has a spot to mount the screen and assemble in the the housing at least. Also got a time keeping IC to play with and put the circuit on the board with the battery needed to keep it accurate.

    Still a lot left to do but all progress is good. I included a connection in the design that will utilize the factory clock connector, this way I won't need to tap any wires for the power or the illumination circuit.

    What's the issue you're having with the clock location? I can print you an adapter for it when you have the final size for your pcb

    No issue with the clock per say, I have a short in my dome circuit atm I need to source though. I have a 3D printer as well so I should be able to print a housing out once I sketch it up.

    So when I got my truck, the clock was not working because the tip of a cigarette lighter power plug was jammed inside one of the power ports. Might be worth checking those for shorts.

    Good info! I'm gonna be pulling the dash soon so I can install my new stereo and clean all the dust out. So I'll be using my multi meter to check everywhere. I miss my interior lighting. :annoyed:
