Hey all,
I saw a video yesterday of a person putting a spring on a table with a neodymium magnet next to it and it started vibrating and giving off this low hum. Of course today I can't find the fucking video...
But it had me thinking:
-What If I got a large PVC tube (4"), screwed holes to attach a spring on one side (I would screw holes around the pipe to have multiple springs attached) and something on the other end of the spring that had a long shaft that could go through a cap at the end of the tube that I could pull on to change the spring tension and pitch (like a foosball pole) or maybe some sort of wing nut that when turned tightened the tension or released it.
-Pardon the quick sketch but I was also thinking of using a rubber washer, spring, then agent with another washer on top to vibrate the spring. Could I wrap some shielded wire around the magnets and attached them to a battery supply? would that increase the strength?
I figured somewhere in the center of the tube I'd attached a single coil pickup (probably a shitty old one from a japanese throwaway guitar that works like a mic, a pot for volume and a 1/4 out.
Ultimately I wanted to create a drone chamber that I could adjust the tone.
Is this possible? I'm a super novice with this stuff and just had an odd blue sky idea.
