Wow, it’s been a long time since I started working on various ways to do digital gauges on the Exocet. I’ve gotten everything more or less working on my old android phone as a test. I may actually stick with that and 3d print an enclosure for that and an analog fuel gauge. However, I’ve run into a slight conundrum: power.
Is anyone aware of an android phone or tablet that has either a separate power port or a second USB input ? The issue right now is that I can either plug into the ECU or charge. But not both. I’ve ordered a cable that promises to split the power off and let you do both from the same port , but I’m somewhat untrusting of that chinesium voodoo.
Boot Animation:
Yes, I know the picture shows me doing 42mph on a runway. It’s just a simulated input at the moment. This would be the UI if I ran a 10 inch tablet. If I use my 5.5inch phone in the center of a display, I’ll change this up quite a bit.

Plenty of phones (including some that are now relatively cheap) have Qi charging. A bit silly to have a fixed device wirelessly charged but you could do it if your mystery cable doesn’t work (seems like it should work though?)
Alternatively, charge using the USB port and use a Bluetooth or wifi ODBII reader to pull data from the car (don’t remember if the donor is too old for that)?

Good idea. I had come across that last night but didn’t really put much thought into it. That might be the answer.
I’ve had bad luck with the data rates on the Bluetooth adapters. I’m also planning on switching from OBD2 to Serial/ Megasquirt pretty quickly.
