Yeah, that’s one thing still on the drawing board. The reason my phone crashes seems to be thermal throttling due to heat buildup with use. That’s another reason I want to build my own device instead of buying one from some company, I can factor in the cooling and try to adapt to the hot environment better.

One thing you need to consider is the temperature in your car. In the summer, the inside of a car could possibly get hot enough to damage the pi.

I would especially advise against relying on battery banks due to the heat, if you’re just going to use it in the car and already going to the trouble of customizing so much hardware I’d find a way to run a power supply off a switched 12v fuse or wire from the car - just convert to 5v/USB power. I’m sure there are generic kits online
Natal@lemmy.world 3 weeks ago
Yeah that might end up being necessary, I haven’t found any easy solution to provide the 5A/5V required by a Pi5. Still pondering the power supply issue.

a.co/d/hh2N98y Something as simple as that, though I’m not sure 5v/3a is enough for a pi5 you’d have to check power specs
Natal@lemmy.world 3 weeks ago
Thanks! I’ve studied this option and Pi5 needs 5A/5V. I haven’t found something adequate yet for that power requirement.

That was my first thought. How do you keep it cold enough to run in a place like Arizona, Spain, or Mexico? It also reminded me of my Windows Mobile days before I had a smartphone when someone on a Windows Mobile forum took a Dell Axim x51v and built a dock for it that exposed all the ports so he could use it with an external display as an infotainment/nav system. He called it the Aximizer. An old android phone with a micro-hdmi port might be the modern equivilant.

I had a Raspberry Pi2 in my car for a few years. The weather here in Barcelona is quite hot during summer, but even if it was left in the car under the sun, it always worked well.
I used it with the official Touch display, but added some physical buttons for navigation and playback as a touchscreen is never as good as real buttons, and anyway after some time, the touch function did stopped working well.
I used Kodi to play media, with a low resolution, “made for car” theme and using an addon to read the gpio buttons plus another one to make Kodi read only. The car adapter I used to supply power did not always trigger a clean shutdown, but having Kodi and most of the OS read only (i. e. no logs), I literally used the same SD card for years without any issue.
I could have used a gps as well (and launched its app from Kodi), but I got gifted a gps so used that.
Now I don’t need this as I changed car, but I still use occasionally the RPi2 with its screen as no matter what, they still work fine :)
Ultimately, I wanted to mention that more powerful boards will require even more watts and more stable power, so it might just be easier with an old board.

The last phone I saw with a micro HDMI port was the blackberry Z10 in 2013
