For the first time anywhere on YouTube - nimo tube shootout! But slowly - in the old-school FranLab long format. Savor all the drama as I embark on a quest to test three different tubes in my nimo clock, one new-in-box nimo tube vs. two very used - and there are some surprises. Plus I set out to discover once and for all whether or not nimo tubes produce X-Rays. Enjoy!

I’m cringing every time she puts fingers on the terminals!😬
Fran, it probably does emit soft x-rays as all electron tubes do but if your power supply is 1.7kv then 1.7KeV x-rays won't penetrate the glass of the tube. Most tube manufacturers eventually incorporated lead in the glass to block but who knows which one. That thing is really cool, thanks for sharing!!
You have three numbers you could make an actual three digit memo clock
Hey, you're in my daddy's territory, now! He had a dedicated screwdriver set up for exactly that purpose, making sure the voltage is discharged safely. I may still have it somewhere, in fact! 🤔 Really cool to watch, I've gotta say – brings back some memories!
they look cool ,i think i like them better than nixie tubes
I remember from school that you require over 25KV on the anode to produce X rays.
Fran, your devotion to and time spent modifying your socket assembly for the two new tubes seems a fitting tribute to the time and devotion of the engineers who originally designed the tubes back in 1059-67.
My guess it is for a selector display.
Exotic, dangerous, eerie & green. I like it!
Pretty Amazing Technology For The Day… Considering The Wheel Was Invented Only A Year Earlier… 😄
Just Kidd'n… 😉
Split Enz Mental Notes LP on the shelf, very nice
You had to put it near-contact, not an inch away. Now I am not convinced yet. Also, is your geiger counter sensitive enough for the low keV energy being emitted?
X rays don’t show up until you get above 13 kilovolts or so.
This just takes me back to a few years ago, my great uncle was very into the field of electronics, and I was just getting into the field of electronics, he passed away 2 years ago, and his wife invited me and my grandpa to go and look at all his stuff and we could have whatever we wanted, my grandpa is a mechanical engineer while my great uncle was an electrical engineer, so they did work on some projects together, my grandpa did the mechanical stuff and my great uncle did the electrical stuff, when we went down to his basement to see what we could find, we found all kinds of tubes, my great uncle was still using some tubes up until he died, in the 40s during WW2 he built a TV for the family out of parts he found and bought. He had everything to do with tubes though, he had a tube tester, vacuum tube analog volt meters, all sorts of stuff, I should have grabbed more. My grandpa has some stuff old electronics stuff, but nowhere near the amount he had. But my grandpa did have a lot to do with electrical advances in the 60s 70s and 80s he worked for HP and made all sorts of stuff for them, he would mill circuit boards, and his biggest project was when he made the parts for the first ultrasound machine developed by HP.
I failed to notice how much larger the digits are on the "new" nimo tube compared with my original burned one. Honestly, that formerly new-in-box tube looks amazing in the clock!
