Things in my junk box:

If you have a project that you think would be really cool but is missing something listed here, let's talk. I want to help people make cool things - if you see something listed here, most likely I would be interested in collaborating with you on your project to implement it.

  • Lasers
    • 120mW ALC-60X Air Cooled Argon Laser, multiline (blue, green, violet), blindness hazard, my baby
    • 1mw He-Ne 632.8nm for display (glass exposed)
    • 10-12mW He-Ne 632.8nm
    • 10mW DPSS 532nm, small and bright
    • A galvo+scanner amplifier setup to make pretty patterns (need to build fancy D/A converters to drive them with an AVR)
  • RF stuff
    • SMA connectors (no RP-SMA unfortunately), type N stuff, coax cables, some waveguide
    • Attenuators, couplers, mixers, whatever hasn't sold on ebay
    • A complete APRS GPS tracking system (ham radio based location transmitter)
    • 2m all band (CW, SSB, FM) transceiver
    • A dual band 2m/440 satellite antenna made mostly of wood.
  • Electronics
    • Lots of random 74XX series logic ICs that I have absolutely no use for
    • C64 SID chips waiting for a project.
    • 4" RGB LCD displays - cheap.
    • Lots of random junk.
