Comment on Part 2 of car Raspberry pi 4 GPS project

For offline navigation on Linux, have you looked at osmin? It was pretty decent on a PinePhone.
How do you handle power-off? Does Raspberry Pi just shut down? My thoughts were to use Alpine or some RAM-based OS that would not corrupt SD card or the hard drive.
I have been messing around with building an in-car navigation from e-waste for a while now. Right now, I settled on an old smartphone with OsmAnd and wrote my own app to view the reverse camera.
I didn’t know about osmin! I might try it out.
For the poweroff, I’ll just poweroff the Pi from the UI and wait a sec for it to go down. Initial testing has me waiting 10 seconds on the “shutting down” screen. That’s short enough, meanwhile I can put my jacket on or something. Once off, I just unplug it. It’s also running on SSD because I don’t trust SD cards to endure constant read/write from satnav so I installed from SD card and cloned the OS to an SSD, it should be more resilient this way.

What material are you using to print your enclosures? I know abs is pretty bad for car type heat…

(I haven’t really used them a lot in the heat yet) Last enclosure was ASA, but AFAIK, black ABS is OK too because black pigment absorbs most of the light/UV, preventing plastic from degrading as fast
