The small singing bowl is resting on top of an electromagnet which gets its power from the DC output of the field kit.The LFO is used to switch the magnet on and off, the bowl is not flat at the bottom so the keyring can never lay flat ... it has to move even if the LFO goes at a higher rate. But it can go to fast and lock the ring into a fixed position (like you can see around the 0:44 seconds mark) ... slowing down unlocks it again. I tried a bunch of stuff but the ring on this large key worked best ... experimentation is the key so to speak. The sound is coming from the GoPro internal microphone, so it's not the best. Want to see more of this type of content OR if you have an idea for an experiment just let me know in the comments below.
