Most amazing dumpster dive ever!!!!

dfdye · 25th January 2006, 02:33 AM

One great thing about working in a chemistry lab is that I often get first dibbs on old or obsolete equipment before it goes to salvage. Usually it is a little boring and a few parts get saved for future lab projects or to repair old equipment, but sometimes there is fun stuff that is worth getting excited about. Today was the mother of all "dumpster dive" moments, and I figured I would have to share it with some people who could appreciate it! I have not finished the total component count, but after 2 X 24VCT 12A transformers and 70 2200 uf 200V caps, I think I will be able to put together a power supply that will be able to drive half of my home town!!!

A few other goodies were some transistors, several nice high voltage diodes, a 60A bridge rectifier, some switches and a step up transformer. Not sure what I will do with that last transformer, but I am certain I can find good homes for the other components!!!

i wish i could find something like that

So far I have had time to run 8 of the caps through our tester, and they are all fine. I hope the whole shooting match works out!

This weekend I will probably start putting together a PSU for a multi-chanel chip amp I have been toying around with building. Since the combined transformers would be ~600 VAC, I figured I would be able to run at least 6 chanels off of the PSU. I was thinking maybe 8, but I'm not sure if I should push it. . .

Any opinions?

you could always make a rail-gun with all those caps!

i work next to the engineering department here in a medical manufacturer... always great finds! I pulled 4 nice big aluminum heatsinks and 4 transformers out of the trash last month. they were 220vac/24vac, but here i have 110vac, so theyre 12vac. so what if i gotta tie 'em all together, free is free!

I think my wife would be a little upset with that idea!

I was actually thinking of making sure all of them are in good shape and trading them off for other parts in case anybody was interested. I even have the ability to "hand match" parts!

Anybody need a @#$%# load of 2200 uf caps??

No doubt! That's what I am going to have to do with mine as well. I guess you could argue that I am using a different transformer for each rail!
