Hi, while shopping for some minor magnets the other day for my balcony windmill project I realized there are some quite powerful magnets that are not too expensive and the idea of a building an Arduino maglev baby cot for my newborn child came to mind.
There are several pages describing solutions based on a magnet, coil and an hall effect sensor. The most serious treatment I've found however states that whatever you build will be inherently unstable (http://mekonik.wordpress.com/2009/03/17/arduino-magnet-levitation/). I don't want my baby to be tipped over and thrown out of the cot in mid air. The idea is to have her floating comfortably of course, maybe with some gentle rocking to promote sleep.
I am also a little bit worried about exposing my baby to strong magnetic fields for extended periods of time on a regular daily basis.
So I have two questions I guess.
1 - Is it possible to build a stable solution?
2 - Can the magnetic fields involved pose any health hazard to small babies?
I was thinking about magnets like these:
Any thoughts and input appreciated of course!
