Thank you. Had fun making the machine and videos and the best thing was there was great feedback and it has helped give ideas to other builders.

On the toroid sizing question- I’m only repeating what others have said on here in the past and the Gecko website but the guide is 1/3 x number of motors x maximum current. So 1/3 x 8A x 4 =9.6 A. I think I would start somewhere there.

Sometimes people use a larger toroid for future proofing, depends if that needs to be considered. I suspect pulling small currents from very large toroids is not very efficient.
