Rover 400 - Victor_Mateos03 - 03-15-2020

I come to present my project and tell you how to install and help the community a little.

I started with the crankshaft as it was an end-of-year project for computer science and I recently bought OpenAuto Pro and I don't regret it.

My first installation was with a Mausberry, Raspberry 3b + power supply with official display and a 4 channel sound amplifier. I have it fully integrated into my car, so I had to take a potentiometer outside with a usb.

As you suppose, starting to have problems with the Mausberry power supply and I decided to remove it.

Now I am waiting for a 12v timer relay to arrive so I can try one of the solutions.

Update:

Due to the difficult access that I had to be able to make any hardware update in the system I have decided to place all the possible components on a plastic plate. I have found a hole in the dash behind the glove compartment and I will put it there since it is easier to access. I got the 12V timer and I already have everything assembled, copy the idea of Wynand, I hope it serves as an idea, I am waiting to mount it and see how it works although I have already done some tests and it works well.

I currently have installed:
Raspberry 3b +
7" Official screen
Ugreen usb sound card
Bluetooth usb ugreen
12v amplifier
To turn off 5-pin relay and timer relay 12V

I leave you a link with some photos of the process, I hope you like it https://bit.ly/3c8mqIX

I have updated my project, I hope you like it.

Just out of curiosity, what about 12V constant backfeeding 12V ignition, since you don't have "one way dioodes"


RE: Rover 400 - Wynand - 05-11-2020

Nice setup, i also mounted mine on a acrylic sheet for easy removal. I used diodes to prevent feedback loops to the power supply and timer.


RE: Rover 400 - Victor_Mateos03 - 05-11-2020

Yes, I'm going to do it too, but they haven't delivered to me yet, I hope to have them soon to install everything in the car hehe

Hi, Victor_Mateos03

I want to do something similar for my Audi. Do you have 4 separate sound channels or are these 2 channels (stereo) duplicated front and rear? If duplicated front and rear, how did you get this from Raspberry Pi3? I have a Raspberry Pi4.

Thx and sorry for my English

 To the sound card I get the four speakers, two on each side, (Left, right, front and rear) to take the audio from the raspberry I have a cable with a mini-jack and a potentiometer to control the volume that enters the sound card.

Update

I received the rectifying diodes and finally managed to finish the configuration, I finished mounting it in the car this morning and here is the final result.

May I ask what the round orange thing is at the bottom of the plastic plate? I don't see it on any of your schematics. It looks like it says SIGMA on it, perhaps?

Hey guys, 

I have created the same setup as you guys but I didn't think about the diodes. I found out this schematic:
https://bluewavestudio.io/community/attachment.php?aid=434

but can you explain why they are needed? Something specific about how car ignition works? Because on my tabletop setup, I don't see any issues "turning" ignition on and off (12V Bat and IGN powered from the same source)
