Homemade liquid nitrogen generator

[imsmooth]

I thought some of the engineers here would like to see some of my work. I put together a website tutorial (http://homemadeliquidnitrogen.com) explaining how to build a liquid nitrogen generator using the Joule-Thomson cooling principle. There is also a 4 minute video summarizing the whole process.

I'm posting this in response to a closed thread on this site

I hope you find this interesting.
