We’ve recently switched from IR remote controls to RF remote controls, giving us better range, better performance outdoors, and no longer requiring pointing the remote. In order to do this without printing all new and expensive circuit boards, we prototyped just the receiver part of the circuit and then attached it to the already assembled boards. This way we could test the circuit quickly. We used the CNC mill at Sector67 to do it. Here’s video of the milling in action.
And the partially completed circuits afterwards.
