farmer888 -- To quote Lebowski "New information has come to light, man."
I'd been wanting to buy another Raspberry Pi, and putting one in my XFi is an option. I'd been thinking a Pi 400 (different motherboard), but now comes the Compute Module 4. I hadn't considered it but I can appreciate the teardown. The plastic had brass inserts for mounting on four sides (L/R/back?bottom) and a slot for the HQ camera ribbon.
It has a 5" touch screen and USB C power.
This episode is an introduction to a series on dropping one into an OBDII vehicle.
I could see one as a desktop machine with external KVM and a camera one one side and microphone on the other with teensy articulated print-in-place 3D printed tentacle arms in the brass inserts.
