This project began much like many of my projects at Milwaukee Makerspace have: an off-the-cuff discussion; in this case, with Lance Lamont about a possible project for Maker Faire Milwaukee. After a few rounds of discussion, we came up with the idea of an electromagnetic crane. I decided I’d attempt to build one similar to this style, and that I’d start off with the magnet. I purchased several small electromagnets from Tom‘s favorite website, Banggood. Thus, the MicroMagnetArray was born:

Nerdy Derby Wheels Keep Rolling!

checking-print
