I really want/need/absolutely-must tidy-up my CNC power cables etc. At present it looks very much like the original definition of PC = 'Proliferation-of-Cables'
I've got a case from an ancient PSU into which my transformer will fit, along with Rectifiers and Capacitors. The three Axiis-drivers will mount externally, on top, and ...
There's space for the Arduino inside the case.
Will the field from the transformer have any adverse effect on the Arduino? Should I try to mitigate it by rotating it as per either/or of the attached sketches?
