So let’s say you need a new clock. Sure, you could go spend $19.99 (or less) and just go buy one, but wouldn’t it be more fun to bust out the CNC machine and build one yourself? Alan Parekh of Hacked Gadgets thought it would be, and he just happened to have a new CNC machine lying around.
Alan cut the gears on his CNC router, used a micro-controller and a step motor, and created a pretty cool wall clock. He explains how he did it fairly well in the video, but his site has even more detailed instructions.
