Thanks for the great talk at the we are developers conference. I would like to start playing with the donkey car which would be a great thing for the kids as well but I have no clue where to get the parts from since the shop delivers to U.S. only if I read correctly.
To answer my own question: RTFM. Docs where helpful here: https://docs.donkeycar.com/guide/build_hardware/#parts-needed
This is my BOM with links in Germany https://github.com/connected-autonomous-mobility/50-hardware/blob/master/build_hardware_ValleyCrawler.md
