Car Project Help

Hi There,

I’ve been testing the use of volumio as an in car audio system. My existing car audio system has a 3.5mm aux so I’m planning to connect to this with the following parts.

RPI 2
Nano Router - Model No. TL-WR702N
usb stick with my music on it.
some form of connector the the power 12v power
Highberry DAC

I have just been testing this setup connected to an external battery via USB cables. Obviously this is not a long term solution, I notice that some people are using UPS such as these and then just connecting into 5v cigarette lighter adapter.

Other people seem to be using these mausberrycircuits.com/

I’m alittle unclear as to which is the best solution? I’m after a simple and reliable solution, and it seems that most UPS’s will handle safe shutdown once the power is switched off in the car.

I was also considering using one of these amazon.co.uk/Rocketek-Socke … VDRRX0NK3B permanently wired into the car power.

The other option seems to be one of these amazon.com/DROK-Converter-S … irect=true

I would really apreciate some help from someone who has a working system??

I was wondering if it’s possible to do away with the router this and connect to the raspberry pi over my phone??

Any guidance would be much appreciated
