Hello all,

I wanted to share a personal project I have been developing over the last 2 years and see if there is enough interest to justify a small production run.

I've noticed that most of the highly customizable Pi powered digital dashes for sale online cost more than $1,000.
Most of them are universal setups requiring custom mounts to be designed.
Other options were vehicle specific and featured poor quality 3D printed dash enclosures.

To solve this problem myself, I have designed my own Digital Dash setup for the Volvo community.
My product is turn-key and easy to install, features high quality, easily sourced components, and has a modular mounting design offering limitless flexibility.
This current design is for the 240, but it can easily be adapted for other models.

Key Features & Specs:
  • Turn Key system with OS pre-installed and power wiring terminated to a Deutsch connector.
  • 32GB Internal Storage (Upgradable)
  • Raspberry Pi 5 (4 GB) Powered
  • 10.4" QLED capacitive touchscreen
  • Only requires 3 wires (12V Constant, 12V Switched, Ground) and a USB connection to the Mega/ Microsquirt.
  • Includes GPIO breakout board for I/O integration (Fuel Level Sender, Shift Light, Oil Pressure Sender)
  • Includes Power Management on-board for delayed shutdown and quick boot-up times.
  • Integrated GPS (In-Progress)
  • High-Quality 3D Printed Enclosure (Fiberon ASA-CF08)
Total Cost will be in the $700-800 range.

Before I finalize the design, I'd love to get some honest feedback from the community.

Is there a general interest for digital dashes in the Volvo community?

For those interested in digital dashes, what features are must haves?

Will be updated as the project progresses

This design may change.
I might also include an option for personalization for those interested.

id be interested. For me just the basics, MPH, Tach, Fuel, WaterTmp, Boost, Air fuel gauge. But could leave the Air/fuel and boost gauge that I have now. IT be cool though if you could set some parimeters, lets say if you went lean all of sudden that d.dash would start flashing red and or w.temp.

I plan on adding GPS speed and fuel level eventually, as well as custom gauge templates. I need to dive into the software more.

Looks great
Can you play videos on it ?

Thanks!

Yup.
It is powered by a Raspberry Pi which is a micro computer.
I have a wireless mini keyboard with a touchpad that I use with it.

I'll upload a video of it in action soon.
 
I’d buy this instantly if you could get it to work in my parameters

I run DIY-EFI speeduino in my 940 which uses tuner studio

I’d need to be able to setup a speedo based on the diff sensor, I’m from the uk and gps Speedos are a pain to use where I am. I’d also really want a fuel level gauge based off the original sensor and an odometer.

Other than that, I’d just want it to show me the basics, coolant temp ect. It would be cool if there was a way of having the dash look like the oem 940 dash. I think I’ve seen someone do similar with a 240

It would be cool if there would be a way to integrate some basic warning lights too !

It shouldn't be much of a challenge to interface the 940 diff sensor.
Same with the warning lights.
I will add that to my list of features to implement.
I believe the TS Dash Pro has a odometer feature.

I'm currently working on the fuel level gauge using the stock sender.

The biggest challenge I see so far will be redesigning the mounts for a 940 and integrating into the stock cluster harness.

How do you manage quickboot and shutdown?

I'm working on the same thing for my 960. Running pi5. Already have a stripped down Linux OS that is booting straight into realdash app.
Safe shutdown left to do, I guess using a gpio pin could work, still researching.

I am using the shutdown manager feature on TS Dash.
TS Dash Shutdown Manager

It lets you set a GPIO pin as an input to monitor if the key is on or not.
With the key on, the pin is held high, and keeps the power on. When the key is off, it activates a time delay relay.
This allows you to set a period of time before the Pi shuts down safely once the key is turned off.
I have screen power wired to switched 12V so that it shuts the screen off and on when the key is turned.
"Quickboot" is just turning the screen on and off within the 15 min timer, since the pi holds power during that time and doesn't need to boot up.
At around 14 min of having the key off, the PI will initiate a safe shutdown.

The 15 min limit is constrained by the time delay relay I used, which only lets you set it to 999 seconds. I could increase this time if i used a different delay relay or even a battery backup.

Since you are not using TS Dash, I'm thinking you could write a python script to initiate a safe shutdown once power is switched off, or with a button press.
