I am using a basic entry level E-bike for my daily moves in town. The original Controller was having some flaws, so I changed it with a other chinese Model, so learned about Signal Names like PAS ( Pedal Assist ) and found out that I could add a Throttle, because the new Controller supported it. Now I like my E-Bike very much with the Trottle.....Becoming gradually more familar with the Technology, I tryed to write my own Controlled Sofware based on a Arduino MEGA2560, first to learn how the BLDC Drive works, second to be able to add any feature I want. Because I wanted not to rebuild the Hardware from the Power Stage, I took a chinese Controller, remove the Processor and solder the 6 wires to control the H-Bridge. Those 6 lines are now controlled by the Arduino.
The result works surprisingly good, as you can see on this video.....
OK, I could not make a "Field Test", because the Hardware is no reliable enough to Build it in the Bike and drive on the streets.
Would be nice to have more enthousiasts to help to design a Hardware Shield for this project and produce a few PCBs. Poeple interested should contact me, I can provide shematics and component Listing for a Shield....
