Magnetic Clock Project
Friday, November 30th, 2007
I have a new project I’m working on, thanks to the speedy delivery of parts from K&J Magnetics who sent me some strong neodymium magnets, and Nick’s Equipment Sales who sent me some high-torque clock movements. The plan is to build a clock something like the mockup on the right, where the clock has no visible moving parts (no hands) and steel balls glide over the surface with nothing apparently holding them in place. The way it’ll work is that the hands will actually move behind the face of the clock (I haven’t decided on a surface yet), and those hands will have magnetic neodymium discs affixed to them which will bond without touching to matched neodymium spheres which will indicate the time…
Hopefully it’ll look neat. I have a much cooler clock that I’m building with Caitlin that’s a pair of crocheted robots that point out the time that maybe I can post next week…
