I bought some Russian Nixie's on eBay a few years ago. I haven't looked lately to see if they are still for sale. Seems like they built them years ago, maybe for a defense project, and now someone is selling off the warehouse full of them. The data sheet is in Russian, but you can figure out the numbers.
@Tyler: Please let me know if you have any questions regarding the project...
I think this is a GREAT project -- I also think that other engineers here on EE Times would love to hear more about it. How did you come up with the idea? What were the design decisions you made (and why)? What issues did you run into along the way... Would you be interested in writing a short article about this? Email me at firstname.lastname@example.org
My name is Tyler Nehowig, I created the Smart Nixie Tube project.
The Nixie Tubes take 170VDC to light -- there is an onboard boost converter to boost 9-12V to 170V. 170V will give a nice little tingle if you accidentally make contact with the output of the boost converter -- although the amperage is very low. I have released an open source design for a laser cut enclosure -- which will protect the circuit boards from accidentally being touched. I'll also be offering these for sale for backers of the campaign.
Thank you very much for taking the time to write about the Smart Nixie Tube Kickstarter campaign! Please let me know if you have any questions regarding the project -- I'd be happy to answer them.
@_hm: What are the voltages required to power this Nixie and control them?
Based on this blog, I think we're talking 100+ volts. But remember that this Kickstarter projec tis nothing to do with me -- I don't know how the designer of this project implements his isolation and safety stuff.
