The New Hotness

  • Vacuum Tube LEDs: 6H6GT Dual Diode

    Having accumulated a set of octal tube base clamps, it’s now a matter of selecting the proper clamp for each tube:

    Octal tube base V-block clamps
    Octal tube base V-block clamps

    The process of shell-drilling the tube base, drilling the hard drive platter, printing a tube socket and case, wiring up the Arduino and base LED, then assembling the whole thing requires a bit of manual labor, assisted by some moderately exotic shop machinery.

    The getter flash atop this small 6H6GT dual diode tube rules out a cap and there’s not enough space for a side light:

    6H6GT - on platter
    6H6GT – on platter

    Fortunately, the base LED completely lights the internal glass:

    6H6GT - purple phase
    6H6GT – purple phase

    The slowly changing color would make a fine night light:

    6H6GT - cyan phase
    6H6GT – cyan phase

    It must be Art!
