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…

    Beautiful Variac (or variable autotransformer). Years ago I got one that is quite useful around the lab.

    I have a few interesting bits that I can post here. Not as "vintage" as yours, but hopefully interesting.

    That TWD120 is really nice - there is a tear-down here:

    Thanks; that is a nice bit of kit indeed, albeit noisy.

     

    At the moment I am trying to make it work with an old Dell Inspiron 2200 running Windows XP, but both yours or shabaz' laptops could drive the TWD 120 very nicely.
