Very cool! I don't think it would take much to make a board small enough to attach it to the back of the gauge (or maybe even mount it vertically next to the gauge as-is to make room for an additional gauge or two.
Yes, I’m confident it could be done, esp. if using surface mount devices instead of through hole components. Soldering those small devices is definitely beyond my current capability, however.
There could be room for 2 additional gauges...which ones would you propose?

Boost and EGT gauges.
It could also make room to flush mount a radar detector in the extra space.
cool. Would it be better (and sleeker) to put a digital LED matrix type display that just shows the temp (maybe changes light color from green/yellow/red if a certain value is reached?). The VDO gauge is cool but a discreet display would be nice.
Wish there was a way to simply tap into the digital clock LCD in the instrument cluster and have it just output the temperature instead of the clock

Or, how about using it to drive the original oil temp guage already in the dash! Oh wait, I'm an idiot, that is the water temp!!! Sorry...
The OP does very impressive and tidy work. Well done!
Great work - Does the feed need to come from the DME or can it come directly from the sensor/sender? Or is it not worth running the cable all that way?

I did a digital oil temp gauge setup on mine using the input from the factory oil temp sensor, but it doesn't change colors. Uses an Arduino for conversion.
I have been working on an updated version of this that uses a wired RS485 network to measure distributed sensors that could be fitted anywhere and displays data on a small LCD up front, with a bluetooth serial output facility to tie it into TrackAddict for datalogging. Because I have been so busy with work and random other problems it's not complete; I will probably finish it over the winter. I have been running the prototype in my car this year measuring oil temp and ATF temp.
Also the complete unavailability of the STM32 microcontrollers it's based on has been a problem, too.
Sorry to revive this thread, but how much does it run to get a PCB made like that?
VERY impressive, I'd be willing to bet you could sell those (obviously not a high volume...)
Not sure if you’re referring to the original design using the VDO gauge, or porschetech3’s design using the digital display. Anyway, I had the original unpopulated pcb made by pcbway.com, just sent them the gerber file, very inexpensive, if I recall the shipping was more than the boards. They can provide an online quote using their website. Purchased and soldered the components, etc. myself, but now I think pcbway will do the assembly also.
I have a couple of spare bare boards, if you’d like to try to put one together.
