So I just finished building an HDR. I'm pretty sure I hooked up all the wires correctly and it seems to work. The indicator light turned on and the electromagnet picked up some scissors and a screwdriver but it seems to be underpowered or something. I opened up my compass app and held my phone close to the electromagnet but it doesn't seem to register any movement on the compass needle at all.
A few years ago I was using a unit that Gibbs had built and the electromagnet seemed to be a lot stronger and make more noise and vibrations if I'm remembering correctly.
Can anyone see what I might've done wrong here?
