Basically a small version of the ring launcher - https://www.youtube.com/watch?v=V690VphqTwg https://www.youtube.com/watch?v=V690VphqTwg
Where the ring launcher works by counter emf that evolves in the conductor, a tuned emf (like for RFID chips) could be made with specific properties. Eg. it might only respond to certain frequency bands and possibly (?) allow for both repulsive and attractive forces by either maintaining or inverting the exciter phase in the board.
- jacquesm 5y agoI'm absolutely itching to give this a shot but I really should be concentrating on other things right now.
- amelius 5y agoYou could let a microcontroller on the puck control the allowed currents. If you do this sufficiently fast, you can multiplex over different pucks on the board. Creating a tuned oscillator could be interesting too, but could also turn out to be too heavy, in terms of component weight.
