Re: Safe shutdown using three relays

That's awesome! I always knew there was an easier way to do this than what I did. Glad to see some well documented alternatives out there. I especially like the idea of using a buck converter w/ USB outputs, cheap and very practical. I had to solder usb headers into my system.

Re: Configurable shutdown period?

You don't need any additional resistors. With a standard 12V relay board, you just feed the 12V signal from the camera on the input side of the relay, and on the output side, you take 1 wire to 3.3V on the pi, and another wire to a gpio pin. You can do the exact same thing with a 12V ignition trigge...

Re: Configurable shutdown period?

As you stated, the relay is simply acting as an interposing relay to isolate the 12V from the GPIO voltage. You can accomplish the same thing by stepping down the voltage, sure. In my case, I already had a relay board in my car as I was using it to trigger my backup cam etc, so it made sense to re-u...

Re: Complete install and setup instruction

hifiberry works fine with my system. they may be problematic, but I haven't had a single problem. It worked fine "out of the box". Hisma, does the OAP volume control work for you? It doesn't seem to work for me, but the main OS control does. Not sure what to do, to get the OAP control to work corre...

Re: Configurable shutdown period?

As mentioned the PW Car PS works fine, as does other variants like the mausberry. I am the person that did the video you linked, and here's a video that explains in more detail what I did (if you didn't find this video yet) -

Re: FM radio with RDS - your ideas for HW

it sounds like to me, the return on investment for developing a FM radio solution is simply not there. I get it. There has to be a middle ground here though. I don't care about FM radio, and obviously folks outside of the US don't care about it either. But from the responses I get to my car build vi...

Re: Connect RPI to Car Bluetooth

I don't know where you are based, but try this external bt module - https://www.amazon.com/Panda-Bluetooth- ... 00BCU4TZE/
I'm using it in my system and can confirm it works for both A2DP and HFP. It's a non broadcom chipset. Only $12 so it's totally worth it.
