Well, you'd have a least one ... I'd like to have tried it!!
No I have 3, my two sons have one each and Mr. Brown has borrowed Maria's one.
But I have re-thunked the idea and if I did make them I would do the changes , but this is a very expensive process tooling cost alone on multi layer PCB is a very costly exercise.
Let alone getting chassis made, crazy we gave all our UK skills away and we can thank Maggie for that.
