Thank you for your insight! I am getting closer!

I just wanted to recreate the device my dad made with me as a kid

I appreciate it, I didn’t realize it was so temporary

Apologies for not being clearer. What I mean to describe is a magnetizer - something that you might put a metal tool through to make it magnetic

That’s correct!

I hope someone will chime in who’s more knowledgeable but, yeah, it looks like an earthworm to me. Just…longer? Not a sewage worm, by chance?

Thanks- I got the thing running through a breadboard power adapter of all things, to confirm the pump was still living, so I will try what you linked! I am beginning to wonder if I wired my last adapters’ poles. So, this might have been user error on my part, doh!

Hopping in here to thank y’all for your insight. It’s been an educational morning!

Forgive my ignorance, what’s Real Debrid?
