Nixie Tube Geiger Counter, moustachenator writes -
A long, long time ago the folks at bildr.org got their hands on some nixie tubes and some components from ogi lumen, and built a twitter follower counter. You can see the post here: http://bildr.org/2010/11/twixie/ At the end of the post, they outline a plan to give away a set of nixie tubes and all the fixin’s required to work them, as well as a voucher for laser cutting from ponoko.com. Well, it turns out I won that contest!
After a fair amount of designing and redesigning, I decided to make my geiger counter look like an old-timey cathedral radio with a detachable wand to check various sundries for radiation. It was a bit more ambitious of a project than I realized at first but I think the results were well worth the effort.
