    Thanks for the posts, Greg!

    Has anyone made clocks with the new demodulation scheme in them yet or is it still “up to us to help ourselves”?

    My old Lacrosse has trouble staying in sync where I live.

    Some Time Nuts special interest group members have ordered the evaluation board.

    IF you are interested in time/clocks, THEN the DIAMEX (Germany) NixieCron clock kit may be of interest. Uses LEDs, light-pipes, and custom acrylics instead of Nixies.

    Hi everyone! Is pin 1 the one I've circled in red, or is it the one I've circled in blue?

    I ask based on the documentation here that says:

    1 = GND
    2 = VDD
    3 = IRQ
    4 = SCK
    5 = SDA
    6 = EN

    Also, a friendly note: looks like they have stopped manufacturing the AM/PM receiver, and will replace it with a "brand new version available in April 2019."

    The LIXIE is a pretty interesting display, some real homebrew ingenuity going on in that video.
    You *KNOW* the guy's a real electronics geek because he has an LED tattoo on his arm ;-)

    I have a similar but ancient numeric display that looks like it came from a digital voltmeter. There are 4 digits and a +/- AC display.
    It uses etched acrylic plates in an aluminum frame, the light source was probably incandescent bulbs.
    I guess it should be called an IncandIXIE display ;-)
    It looks pretty good when driven with white LEDs. I hope to make it into a station clock/thermometer.
