Show us your junk!

neuromodulator
neuromodulator over 6 years ago

I love junk, specially when it can be fully restored, has interesting parts or uses interesting technology. Most of the junk I get, comes from the university, its dumped because its either too old or it doesn't work anymore. I'll start this thread by showing one of my latest junk acquisitions:

This is an autotransformer made by a company called "The Superior Electric Co" from Bristol, Connecticut. It was apparently build in the 60s (according to what I found in the net) and supports a max of 1.2 kva. The autotransformer works as expected but of course it shows its age, the rubber cable is not in the best condition and so isn't its paint. In the future I may repaint it and replace the cable but for now its good enough as it is.

 

Have you also found nice junk? Show us!

    Here is the first processor controlled instrument I designed. Intel 8748, code hand assembled on paper and entered into Intel desktop dev system by hand in hex. Not really junk, but not very useful now…

    While looking for something else deep in the "archives" I came across my favourite scientific calculator. (circa 1975) It still works fine. The LEDs were so power hungry I eventually built a power supply…

    In the spirit of your original request (show us your junk!), here is some of my junk.  One of my many past jobs was working for a life sciences company that built instrumentation for various forms of testing.  One of their products was an autosampler that would draw vapors from a series of vials, arranged in a rectangular array.  This product suffered some issues from it's original design, so the company did a mass recall and retrofit of the device.  The result of this recall was a large number of XYZ stages (equipped with stepper motors, gears, belts, leas screws, anti-backlash devices, low friction slides and bushings, etc.)  that were deposited in the dumpster in the back of the company.  Not being opposed to 'dumpster diving' at the time, I had acquired many of these XYZ stages.  I sold many of these on Ebay (~$50 to $80 each), gave some to friends, salvaged parts off of others until there were only a few left over as I prepared for my big move to Texas (which I likely gave to the same individual that I gave my autotransformer to).  Here are some of the pics that I used on Ebay:

    Very nice Gene!, you probably could build a 3d printer with those things or maybe a PCB CNC depending on how precise they are. Or maybe something else, like a "button endurance tester"...

    One of my friends used these to build a 3D mill/router, that he used for lightweight materials for fabricating model airplanes.  He also used some of the parts to build a boom/gantry for his microscope. This did predate the popularity of 3D printing, but not a bad idea.  This was just one of the many treasures that I rescued from the trash, including a great collection of raw materials (delrin, steel, brass, copper, stainless steel, etc.).  I used the pulleys, belts, motors and some motor drivers (same device, but different dumpster dives) to build some heavier scale robotic platforms.  It was a sad day when they started locking the bins up, as the vendor that was hauling it away claimed that all that was left was trash.
