Hello All!

My name is Ryan, I'm 37, from Spokane, WA, USA. I am a very amateur electronics 
enthusiast. As a kid I liked playing with the Radio Shack 200 in 1 kits but 
after the age of 13 or so my interest waned until about three years ago when I 
thought I was buying some numitron tubes that ended up being VFD tubes. From 
there I saw an analog Nixie clock that someone had made using relays and 
rotating PCBs to indicate the time. I bought a handful of IN-2 tubes because I 
thought they were the smallest and could maybe make a watch from them. Since 
then I have increased my collection to fifty or so tubes. I buy the tubes with 
a project in mind then squirrel them away until I have the rest of the 
components to build them. I use KiCAD for my PCB design.

So far, I have built a couple nixie watch kits from labkit.ru and one VFD watch 
from the same source. I have also built two of Paul Andrews nixie pendants. 
That's pretty much it. Now my girlfriend wants an IN-18 clock for the living 
room so that's on the list as well.

I am currently trying to design a watch using IV-16 numitron tubes and am 
making some necklaces using IN-19 tubes.

Thanks for adding me to the group, I am primarily here to see your projects, 
get a bit of help when I can and hopefully find some tubes I need when I have 
exhausted my sources (or learn of new tube sources when I can!)

Happy New Year, everyone. If you built a new clock last year with a used or 
cheap DS3231, check the date to make sure it's correct.

I posted about this 2 years ago when I found another fake clock chip.
