A micro-actuator made from a 0.13mm thick flexible PCB! It is basically a coreless flexible electromagnet, that can attract or repel neodymium magnets.
This thing can be used for tons of applications! Check out the playlist below for all the things I did with it:
I suggest using it with a N52 neodymium magnet. It can be controlled either through a single transistor to actuate two positions; off position and the attraction/repulsion position. It can also be powered with an h-bridge circuit to get three positions - off position, attraction position and repulsion position. By switching this transistor, the coil can be flapped with any frequency up to 60Hz. I recommended an operating voltage of 4.2V (1s Lipo) which draws around 180mA.
I hope you enjoy experimenting with it!!:)
