    My kanthal rheostat lets me drive both bulbs, and keep them biased a little so the thermal shock is reduced.

    Why is the LIS2DH temperature offset unspecified/uncontrolled? The datasheet sucks BTW, reading it you'd assume absolute temperature.

    The prettier bulb is pretty much the same, ohmic above and below a knee. Starts glowing at 1.25 volt, good brightness at 3 volts.

    The long and skinny light bulb is pretty ohmic below 1 volt and above 2.5 volts. It starts visibly glowing at 3.75 volts. Science!

    I didn't blow out a stylish bulb on this one, and it has a far more conventional construction. I was worried it would crack in the annealer.

    Runs orange hot at 2.7 volts, the filament it molybdenum so I don't wanna push it too hard.

    The filament started with some hot spots but I annealed it carefully. Still slowly darkening the envelope.

    My lightbulb works! Not sure I want to thermal cycle it too much blinking for the competition...

    Yes Valve is hiring computer vision people. I get asked this a lot. We are always hiring all disciplines and SteamVR HMDs have cameras!
