it's a very very cheap RCWL.
Search something like this : RCWL-0516 Microwave Radar Sensor Switch Module

Having the radar sensor behind the wood is a cool idea.  What kind of radar 
sensor did you use, if you don't mind me asking?

[neonixie-l] Re: Argon Piranha

[Robert G. Schaffrath]

I always found Argon have an interesting color. My late father was a 
Professor of Chemistry and I still have all of his elemental gas discharge 
tubes that I fire up occasionally. Years ago I posted a simple website 
demonstrating them all at http://schaffrath.net/Spectra.  The Argon tube is 
at http://schaffrath.net/Spectra/Argon.jpg. Years after he passed, I added 
Chlorine and Mercury Vapor tubes to the collection which is why their 
pictures are different. It interesting to see the different colors that are 
possible if other gases were used. Of course as someone posted on the Nixie 
Clock Facebook page, a lot of research went into making Neon work right and 
simply swapping in one of these other gases would not have been so simple.

Somewhere I still have some fluorescent lamp starters (remember those?) 
that used Argon instead of the traditional Neon. You would see a bluish 
purple glow through the little hole in the end of the starter instead of 
red. I would take them apart and light them up using a small hand crank 
magneto but they do not provide continuous light as they momentarily short 
in order to provide the starting function.
