What to do with an old power supply and ethernet cables?

The answer is: magnetize screwdrivers! Oh, and you'll want a piece of PVC pipe or something.

Remind me not to store my screwdrivers and hard drives in the same box. I kinda went overboard with this, and I have more Ethernet wire left. My goal is to reach around 5 ohms or so. Right now it's about 1.5 ohms, so without measuring I'm guessing that's pulling about 8 amps off the 12 volt rail. It gets hot enough if I leave it on too long it burns out. (this is coil #2!) It only takes about 10 seconds to charge a screwdriver to the point of being able to pickup a bunch of screws at once. As long as it can pickup one, it's usually good enough.

As a side note, they sure don't make stuff like they used to. This is what happened when I went to unplug a new Christmas light set:

Oops. Definitely a good idea that I'm installing a GFCI outlet for that.
