Interested in Liquid Nitrogen Cooling?

(Please don't move this thread to For Sale! Thx!)

If you're interested in Liquid Nitrogen or Dry Ice cooling, I finally got around to making a container feasible for this task. I currently have a test run of four containers, but I will make more later. After looking at the many designs of liquid nitrogen containers, I feel that this design is the most affordable, functional, and safe solution to date.

I've taken a solid rod of Aluminum and had the insides milled out to create a solid cup. As I will be selling these, this way was really the only way of going about making a container safely. The other ways would be to weld/solder/epoxy a copper plate and pipe or copper plate to aluminum. Apparently welding copper and aluminum together is not the best idea. Personally I'd love to do a solid copper cup, but that is just way too expensive. Going with a solid Aluminum container is both semi-cheap and works just as well as copper when you're running -200C temps :P

With a 1/2" bottom, 1/4" walls, and a 6" height, it's a nice size for LN2. If you choose to use dry ice, you'll need get yourself small chunks, or break up big chunks.

The mounting solution is an improved version of what the Japanese are doing. They use a two hole diaganol mounting. What I've done though is added four holes into the hold down. This allows you to use a socket 462 or 478. If a new motherboard comes out with a new mounting solution, all you need to do is drill new holes into the mount and you're set!

If you're confused by my description of the mounting, just look at the picture.

Anyway, I will be putting up a page on my site, Maximum OC tomorrow if you're interested in pre-ordering from the second batch. The price is $125 (actually $127 as there is a $2 paypal fee) shipped to anywhere in the Continental US.

EDIT : THE PAGE IS UP!

For international orders, just send me an e-mail.

So without further adieu, here's the pic. The finished mounting bar will be cleaner looking btw :P

would you not be better off, insulating the top 99% of the cylinder, so as to improve longevity of the charge. obviously a big advantage to have it last as long as possible between re-fills..... right

Yes I will be insulating it for sure. I haven't purchased any yet though.

I'm not sure about how expensive these are from a buying perspective as I've never used anything crazier than water - but from a "machinists" point of view I can't help but thinking 125 is extremely excessive, I could make something similar using Alu round bar stock, and maybe 10 minutes time on the lathe or 15 minutes on the mill - and get a good level of precision. Since I have free access to these tools (as does nearly every other student) the only cost would be labour (aside from materials). And my guess of the material cost puts your labour at nearly $100, or $400/hour. Obviously the mounting hardware also has costs associated but, they appear to be minor to me.

Maybe I'm completely missing something you're doing in the design, or marketing process, but I'm just curious if you're getting ripped off by a machine shop, raking in the cash, or there's really something special in what you've got here.
