More Fun with Chemistry

I've continued the electrostripping. Tonight I started on the final (and largest) section of the legvise.



I'm using a much larger tub now, and I still can't fit the entire part inside. I was forced to upgrade to a large power supply after the previous one melted down. Literally -- it got very hot after a few hours and started to blow fuses. I took it apart and found a solder trace that had melted, shorting itself out. So I went down to Fry's one night and bought a nice, big, actively cooled replacement.


This is what it looks like after maybe 10 hours of use in 15 gallons of water. Thick, slimy, and really quite disgusting. It bubbles occasionally. This is the primordial soup from which Daleks would evolve1. And I get to stick my hand (now my entire forearm) into it regularly. Yeech.

1: Yes, I know that Daleks were created by Davros as a superweapon in the war between the Kaleds and Thals. Duh.

I take it back. I got the connections tighter and now it's drawing ... way more than 6 amps, which is the most this PS can supply. It's in constant-current limit at about 3 volts, so I'll have to hook up the 5v@80A one next.

bubbles aplenty.
