The New Hotness

  • X10 RR501 Transceiver: Heat Death

    Must be something in the air:

    X10 RR501 Transceiver - overheated Zener
    X10 RR501 Transceiver – overheated Zener

    Another overheated Zener in another shunt power supply!

    This BZY97C is still a diode, although I didn’t test its 68 V breakdown spec. I have no idea what they’re doing with that much juice inside an X10 RF box and have nowhere near enough interest to find out.

    It still doesn’t work after a Laying On of Hands: out it goes.
