Post the last thing you salvaged

[kevin gilmore]

So this thread is like the "post the last thing you bought" thread

except the rules are that you had to dumpster dive for it.

Here is my latest find

absolutely over exposes the camera even on iso 150 and f32.

4 x 150 watt flood.

Less lightbulb soon.

Yes, because in the days when copystands were in common use, film with an ISO in the single digits with reciprocity failure issues setting in after just a few seconds was common. That datasheet recommends 4x 200W bulbs, 1 sec exposure, and ~f/8.

[nikongod]

Less lightbulb (anything) soon (ever).

Where is Kevin, and what have you done with him?

Does replacing the motor in my 20, check that, 25 year old beard trimmer count?

I like this thread idea. My community dump has a separate pile for electronics right next to where you drop off the rest of your trash. Pickings are slim, mainly broken computers, VHS players, and CRT TVs and monitors. Sometimes good stuff appears though. My most recent acquisitions were a Panasonic ghetto blaster from the 80s (my 3 year-old son's introduction to cassette tapes is nigh) and a Yamaha Natural Sound receiver, which needs its pots cleaned but otherwise sounds promising.

I used to dumpster dive a fair bit, mostly at Future Shop. Functional cordless mice and keyboards seem to make their way into their garbage frequently, for whatever reason.

I did not think Kevin had that word in his vocabulary! Someone must be holding him hostage and usurping his posts!

Good thread idea, though I don't dumpster dive, but might if there was anything around here worth doing so for.

I suspect Kevin will do something like install LED floods of a specific color temperature (and eye-watering price tag) and then fabricate some electronic ballast dimmer pack for the whole thing ...maybe a 4 channel one for independent adjustment.

[kevin gilmore]

Well dimming those flood bulbs results in the typical shift in color temp.

Tried 75 watt halogens, don't really like them. I have some 50 watt ones i have not tried yet.

Tried 15 watt cfl bulbs, ok but... color temperature shifts and warmup which really annoys me.

LED bulbs it is. Probably i will spend about $160 on the bulbs plus

i have suitable dimmers laying around. 2 dimmers, front and back just like

the switches at the bottom of the thing. At least no shift in color temp.

And no gobs of heat suitable for melting stuff either.

I really like the antique radio. Do realize that the entire chassis is electrially

hot, and all the filaments are in series on the 110 vac line.

Which is why among other reasons the entire case and knobs are plastic.

I did also want to point out that my mantra that "if some is good, more MUST be better"

is not always true.

Case in point, my corvette is 1300 lbs lighter than my previous jaguar S type R.

So 25% less car gives me 25% more mileage and 50% more fun.

Similarly too much light for a modern digital slr is also a bad thing.

Most of the lenses have their sharpest focus and minimum aberations at two

stops down from fully open. So if you have to put stop the lens down to f32

you are not going to get as good a picture. Once you crank down the fake

iso number as much as it will go, and have the shutter as fast as it will go

the only thing left is to reduce the amount of light. I measured the work

surface at over 2500 foot-candles (meter maxed out) with 4 x 150 watt bulbs light.

I noticed the cuddly soft toys in the bottom left corner.

Must be for consolation purposes when the builds don't co-operate - or presents for Grawk.....

Need one of those to take pictures of my bottles..

My wife works for a university engineering department. About a year ago they cleaned out the labs, tossing out a huge accumulation of "obsolete" parts. By the time I found out about it, almost everything was gone. I did manage to salvage 25 or 30 new testing RCA red base 5991 and 5992 out of a dumpster filled primarily with coffee grounds, week old lunch remnants, and half filled old milk cartons. Really needed a shower after that one. I kept a dozen or so of the red base RCA's and sold the rest on Ebay. Netted about $250. Not bad for 15 minutes of work. Still pisses me off about what I might have missed.

I'm always on the look out for interesting stuff in garbage cans, garage sales, thrift stores, etc.. Used to find things on a regular basis ( Fisher 500C, Harmon Kardon Citation, Klipsch Lascala). Not much anymore.

[mrarroyo]

Eico 625 tube tester.

[blubliss]

I don't need these and would give them away if anyone wants them, not sure what could be done, maybe Frank could make s case

Pretty nice aluminum. There are around 30 I think.

[CarlSeibert]

Those are cool. I'll ask Bonnie if she's into making aluminum jewelery.

Found this brand new in the box, never used. Batteries in a seperate

bag, and immediately dumped in the used chemicals pile.

I have no idea how old it is, i figure late 1960's

[acidbasement]

Necrobump!

My friend was going to throw this out. I said "mine!". It's a Mitsubishi LT-90 linear tracking turntable with the accompanying DA-L90 seven-cassette deck receiver combo. Seems to work perfectly. It's very '80s, with the seven-cassette drawer sliding automagically out from the receiver when you push the button.

Not that I needed it, but it's pretty neat.

Playing Black Sabbath through my old psb alphas, it's a pretty thumpin' mid-fi throwback.

Just now noticed this. Dat font on the meter.

That D3 is nearly as sharp as a D800. Which lens did you use? 50mm F/1.4?

[kevin gilmore]

28-70 f2.8

the lenses make all the difference.
