The New Hotness

  • Vacuum Tube Lights: Plate Wire Plug

    After replacing the WS2812 LED in the 21HB5A socket, I drilled out the hole in the disk platter for a 3.5 mm stereo jack, wired a nice knurled metal plug onto the plate lead, and it’s all good:

    21HB5A - Audio plug cable
    21HB5A – Audio plug cable

    The plug had a rather large cable entry that cried out for a touch of brass:

    Audio plug - brass trim turning
    Audio plug – brass trim turning

    Fancy plugs have a helical spring strain relief insert about the size & shape of that brass snout; might have to buy me some fancy plugs.

    This time, I got the alignment right by clamping everything in the lathe while the epoxy cured:

    Audio plug - brass trim gluing
    Audio plug – brass trim gluing

    I flipped the drill end-for-end, which was surely unnecessary.

    It’s now sitting on the kitchen table, providing a bit of light during supper while I wait for a WS2812 controller failure. Again.
