Vectrix VX1 MotorController OpenSource/DIY

[prensel]

I finally decided to put some TLC to my next project which has been gathering dust for ..say about 3 or 4 years....
This project is focussing on making a drop-in replacement Vectrix VX1 motorcontroller using as many of the OEM controller parts or better/cheaper parts together with the OpenInverter board.
At least the MC backplate/coolerplate has to be used as this act as the mounting plate as well.
Since the VX1 is using mainly CANbus comms between the InstrumentControlModule and charger (can probably be left out when using the OpenInverter charger capabilities) this protocol has te be implemented as well.

Love the Vectrix, nearly bought one of the few in Ireland. The motor has an encoder, correct?
Maybe the Honda IMA-based Lebowski is the right size and Roger (Kiwifiat) sells conversion boards for this inverters - I'm running one myself.
Not much CAN, though, but likely tuneable to the funny throttle the VX-1 has (regen on roll forward).

I have also thought about this for some time, not sure if I have much time to spare for a project unless forced by a dead MC.
To me it seems that doing something like this project seems the path of least resistance https://github.com/kaminaris/GigaESC as FW is fully open source and all of the VESCs I have used have been eons ahead of other BLDC controllers in terms of functionality and actual "feel" of use.
I have not used any zombieverter to comment, so maybe it's a much more sane approach.

Problem is that no matter how you approach it (unless going the hacked IMA path) - it would still end up costing 500+ish € when all is said and done.

Another problem I see is lack of compact power bricks for HV->12V dcdc, so most likely something like GigaESC power board + external server power supply should be used to run all of the other onboard electronics.
