Yes, Yes,
Went to the track last friday but Murphys law dictated.
All what could go wrong went wrong.
Bluetooth connection with my laptop failed.
Some loose wires shorted and blew the BT modul later.
So this week I reworked the controller mechanics and switched to an Arduino Nano.
So now all is on the controller board. Only the driving FETS are on seperate PCB.
See picture of the latest controller. Again use the handmade handle.
Satisfied?
