The New Hotness

  • Beckman DM73 Circuitmate: RIP

    I’d added Mad Phil’s trusty Circuitmate to the tool kit I carry along to Squidwrench:

    Over the last few months it became increasingly erratic, eventually got to the point where slight pressure on the case would blank the display, and finally didn’t turn on at all. Yes, I replaced the batteries.

    So I took it apart:

    Nothing seemed particularly broken and, even after resoldering all the joints, it continued to not work at all:

    If you want to try your hand at instrument rehabilitation, let me know.
