Hello!

In the past I made my custom Lambda controller to a 52mm gauge housing.

the plastic housing was made from black POM plastic. my friend made it with CNC machine. it was about 10 EURO/ piece. left a few piece, if you want I can sell you.

sorry for my poor english

Ran into another flaw with the PCB that prevents being able to use it with a stepper motor to drive a needle. Now waiting for the new revision to come back from the fab house.
I would post code for the oled display version, but i have not written anything other than a very basic proof of concept so far.

Bit of a preview of my current thinking for the OLED version.

Nice. Are u able to change between gauges on one gauge without. Changing anything in the tune file?

I had intended to be able to program what each gauge does via a serial cable, but unfortunately that is not going to be possible. it will be very easy to flash new firmware for it though, and i will provide multiple firmwares for various gauge types.
there will not be any buttons on the gauge itself, this is meant to be a very simple single gauge that just does one thing but does it well :)

got coolant temp, intake temp, and vac/boost coded up. not too sure what else would make sense for the oled version. screen seems too small for a tach.

oilpressure, oiltemp (via generic inputs), maybe also fuel pressure?

I'd love to see a stepper version that can be used for tach, preferably with a settable scale, or code for a number of scales.

Gotta say, I'm well impressed with the project! Please keep at it.

i do want to do generic inputs, but i am not (yet) sure how that will work as i do not (yet) use them in my setup.
the stepper version will definitely have a tach. i will do my best to make everything as configurable as possible, but it will have to be done in the source code and recompiled since the processor i am using has no way to store configuration info.
stepper version should be coming soon, the revised pcb is in the mail.

new pcb is here, doing some initial testing with the stepper motor. have some issues to work out, but they all seems to be software side. ill try to get stuff posted to github soon.
i have some contacts for doing pcb stuffing as well so might be doing some mass production of these if theres enough interest.

stepper version hardware is confirmed working and sitting here running a test pattern on my workbench.
the stepper motor has a range of up to 315 degrees, easy enough to scale smaller in software. 3 steps per degree, so good resolution.
