Finally got around to documenting the OpenAuto Pro Project for my 2000 Crown Victoria.
Video(s) of the project:
Parts involved in this build:
Raspberry Pi 7" Official Touchscreen - https://www.amazon.com/dp/B0153R2A9I/
Raspberry Pi 3b+ - https://www.amazon.com/gp/product/B07P4LSDYV/
12V 4 channel relay - https://www.amazon.com/dp/B00LW2GM84/
5V 1 channel relay - https://www.amazon.com/dp/B00LW15A4W/
12V - 5V 10amp buck converter - https://www.amazon.com/dp/B01M03288J/
USB sound card - https://www.amazon.com/dp/B016CU2PEU/
USB Bluetooth Dongle - https://www.amazon.com/dp/B07J5WFPXX/
Startech USB 3.0 4-Port Hub - https://www.amazon.com/dp/B004C3W25M/
The Crown Victoria stereo area was just a little bit too small for the 7" raspberry pi touchscreen, so I designed the screen mount to sit slightly proud of the opening. It then seemed natural to stack the relays & buck converter behind the pi. You can see my design for the mounts below:
The whole set up takes very little space, requires no modification to the dash, and installs like an aftermarket stereo. The (bulky) bezel of the raspberry pi touchscreen provides a clean look imho.
Here's a photo of everything installed and mounted behind the touchscreen. Please check the above video for a more complete breakdown.
Everything is wired to use a 3 relay set up. I can't find the original post, but please credit to the author. I used this schematic:
Perhaps some of the more electrically inclined folks can let me know if I need a diode in that set up. I'm obviously using a 12v 4 channel relay (instead of two 12v relays) to keep things more compact. I also use one of the extra 12v relays to control illumination on the backlight.
It has been a fun project during lockdown! The final step is to re-print the mounts in ABS plastic. They're currently printed in PETG which melts quite easily in an enclosed vehicle during the summer (even in the shade). But to print ABS, I need an enclosure for the printer... and that's another project.
All the best, -drivers.ed
