Nah, I saw the heating coil was the right resistance. Then, the shiny metal coating on the inside of the tube was not oxidized, so the vacuum was likely good. Nothing rattled, so a short was unlikely. It was designed for 6.3V.
So at 5V the worst that could happen was that the heater coil fizzled and died with some sad noises. Well, maybe no noises, because of the vacuum and all. Some form of sadness though, surely.
The more alarming things I’ve built over the years aren’t so much “duck and cover”. They’re more of the “spend a all day doing data analysis, then know something I probably shouldn’t” variety.
Lmao that is awesome.
I recon you had some sweaty palms that first time, i recon I would have hid behind a wall.
