In his continuing quest to reduce the parts count of a robot as far as possible, [Carl Bugeja] has hit upon an unusual design: robots built of almost nothing but PCBs. Admittedly, calling these floppy ...

Pulse Electronics offers flat-coil planar transformers that use a copper fill factor that is twice that of a PCB, so the DCR (direct current resistance) of the primary winding is reduced by 50% and ...
