Printed circuit board made for one of the Student's projects. The first double-sided board (copper tracks on both sides) I've designed and manufactured in about ten years. It's much easier making them with just the copper on one side.

Tested, and it works okay. Supposed to operate several motors in an underwater ROV (remotely operated vehicle). There's talk of it, the complete project, being tested for real in Loch Ness. If so, it may never see the light of day again...
