How you will learn

  • Widgets: Drag, drop, and experiment—arrange batteries, close switches, and see the results in action.
  • Byte-sized watching: Quick videos that simplify complex ideas into easy steps.
  • Quizzes: Prove what you know and strengthen weak spots with focused, fun questions.

Not A False Prophet: endorsement from the EV community

  • "The cabs converted by Janosch were excellent, both to drive and in implementation. The fact he's driven it up and down the country is testament to the reliability and quality of his workmanship. One of the coolest cars I've driven."

    Jamie - EV Converter
  • "I have driven a vehicle Janosch converted and have been following his work for more than two years now. Not everyone wants to ask questions in a public forum, someone who knows what they are doing and is available for 1-to-1 conversation is exactly what I would have wanted when starting my own EV conversion."

    Tom - EV Converter
  • "Janosch is an active community member and has contributed unit tests to the OpenInverter code. He is a clear communicator and knowledgeable with extensive practical experience. Having built multiple identical vehicles he also knows a ton about firmware development. Highly recommended."
