content: I'm in a small city and it's pretty hard to get stuff besides CRT TVs and printers. Everything else people just toss it because they don't know people like us would want it.I was finishing scrapping a laser printer, and I had no idea about the toner, and I spilled it all over my legs/feet/carpet. Thank the gods it vacuumed up.However I just realized hours later my nose is clogged with it and I went to out super, LOL

content: Ow, sorry to hear that. Vacuuming up toner is actually rather dangerous as it is fine enough to pass through many vacuum cleaner bags, and is also conductive, and can cause sparks or destroy electric motors. It's suggested to only use special vacuum cleaners designed for that purpose:http://www.crawfordtool.com/3M_servicevacuum.htmlIt's a good idea to breathe as little toner as possible, since it can be respired deep into the lungs.

content: Whoops. Yeah I took apart a printer the other day- fortunately neat. Got a few DC motors out of the thing and basically just a few big caps and coils.Disappointment, really. Motors were nice, but a basic desktop printer is kind of empty, so lots of trouble for very little.Made a fume extractor out of some old PC fans though ().

They sure are a work of art inside

content: Picked up an 80s active graphic equalizer off of the curb walking around the neighborhood a couple of weeks back. Probably will just salvage all of the sliding pots, op-amps, transformer, etc., from it.Picked up a 50s RCA console hi-fi system cheap today. Turntable, AM/FM(!) radio, mono output with a 6V6 push-pull output (so probably about 15-20 watts) driving a 12" and two 3.5" speakers. Lady I bought it from said it did nothing but hum one time she turned it on, no surprise the filter caps are bad. I was originally thinking about parting it out, but the pictures she had did it no justice, it is actually a nice piece and would probably clean up nicely with just some furniture polish and a steal for the $25 I paid. Don't really have room for it here at the house, so I may just re-cap, check the radio alignment and flip it.
