Hi everyone

I`m just finishing swaping engine in my camaro to LT1 and I realized that my speedometer won`t work because it is mechanical.

I`m wondering if someone will be interested to DIY instruction to modife old speedometer into electronical one? I`m building such thing and I can make an instruction for that and share with all documentation.

On the film u can see that odometer is working. Waiting for parts to finish rest of it.

Sorry for english

 

Yeah that would be a good write up. I think most people either switch to an electric gauge or get that Jaguar converter box for 300 bucks. So more options are always welcome

 

Just received some parts. And another film

 

After problems with transmission and optispark issues (now) speedometer works




costs ~30-40$
2 steep motors
uC atmega8 with PCB and some cheap parts
needle (correct me if I`m wrong) printed on 3D printer and painted

edit:
In future I will increase the resolution by software, on the film can notice that needle jumps a little
