That's the unit. Like I say a raspberry pi mini computer runs it all. Cant remember the spec of the motor, think its brushless.

My mate that built it wrote a program to operate it. Taking the pulses from the gearbox sensor and converting it to motor speed to spin the speedo cable to the appropriate speed. This is fully calibrateable via smart phone.

I'm just on with fitting another MTX75 in the car at the minute then as soon as lockdown eaes the box of tricks will be fitted.

It's been fully tested on a test bed using a pulse generator.
