Show us your junk!

neuromodulator

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!

  • This is old junk I definitely can live without : )

    A turn of the century laptop.. I bought it used, it is a Pentium with MMX : ) I have not been able to power it up for years because the supply had died, but I tried it with a bench PSU today and it worked : )

    Booted up to Windows 95 : ) I didn't run it for long because I cannot remove the battery, the door is stuck. Still, it's Ni-Cd, about the most rugged battery technology ever.

    It has a floppy drive slot : ) and a cdrom which ejects into the lap (visible at the lower-right). The in-built trackball was great though.

    It doesn't have a lot on it.. (after I finished with it, my mum just used it for driving theory training CDROM stuff for a while).

    There's this ancient PCB cad package, that actually worked, but very primitive. Also it's got a 56002 compiler that I may copy off before finally throwing it out.

    There's no USB socket. But it has one of the first ever Wi-Fi cards.! The current software on the PC is for WEP, so I cannot connect to any network : (

    Here's another piece of now-useless junk.. it was home-built microcontroller board, using a 68HC11 chip. There's a nest of wiring between the PCB sandwich. One IC is missing, it's a MAX232 chip (the serial port is at the lower-left). The big chip is EEPROM (this particular microcontroller had external address/data bus capability).
