No code, no PCB, just a Shitty Add-On for hackaday #Supercon living in the moment.

Now I just need to find a random SAO to pull the connector from. But yeah, this thing is just a ghetto DIY slip ring made of pogo pins, a selector switch from a resistance substitution box, a nixie power supply and a Burroughs 122P244 nixie tube (with bonus Krypton 85 inside).

And now it's documented on Hackaday

Also when you're done looking at this you should totally check out my more interesting project launching very soon on Crowd Supply

@hackaday ... but does it draw less than 1.1 millihorsepower, as required by spec?

@hackaday It only draws ~0.32 millihorsepower (130mA @ 3.3V, please check my math) But I'd give all that credit to @omnixie_usa, who make crazy efficient 180V power supplies.

Neat! Any exposed HV on those pins or all safe? You wanna be careful!

The HV stuff is kinda tucked under the tube and the switching happens on the path to ground (low-side). So it’s “safe” but that really depends on your definition of safe. Like I’m totally comfortable touching it but also would get sued into oblivion selling these on Amazon.

@hackaday 🤔

@hackaday looks beautiful

@hackaday Cool!

@hackaday Thanks! My favorite part is that it's like actually done so I don't need to think about it until November. Things with firmware in them never really feel "finished."
