In my last post I reported about my new led headlights and what a great addition they are for my bobbycar. They increase not only my own but also the safety of other (sidewalk-) participants. Sadly the metal band construction from last time did not last very long and the lamp broke off during a…

In one of my last posts I reported that trying out new parameters like a higher speed limit, higher current limit, enabling field weaking and other changes always require me to completely disassemble the bobbycar and everytime I have to do that, I scratch my hands alot and I start bleeding. It’s about time to…

We will reuse the Motors, Electronic PCBs and maybe also the battery of old (broken) hoverboards. That should make the electric bobbycar really…
