I'm a recent viewer of Project Binky and I have to agree that the work they turn out is amazing but more than that, their approach to problem solving is fascinating.
I'm still playing catch up and last night I watched 10 and 11 which included a whole section on bump steer and Ackermann.
As I'm still playing catch up, no spoilers please for the next week or so until I get to 19.
I don't want to know if Nik smashes one of his tea mugs in frustration.
