TPMS - Plans for pressurized vessels?

Does anyone have a simple solution for building a small, pressurized vessel for "storing" your tire pressure monitors in? I have three sets of wheels and there's no way I'm buying monitors for 12 tires and paying to have everything synched up to my computer. I'd rather make a small pressurized can to put them in and velcro it under the seat. What works that's safe and readily available?

 

I can picture a custom made metal container with a lid that you tighten with a spanner wrench and has a rubber gasket. Need a shradder (sp) valve in it to pressurize. Best I can do. Without a doubt custom made.

You could also put a gauge on it as well. You'd need a machine shop and a welder. Make it out of aluminium.

 

some guy on here said he bought a wheel barrel wheel and stuck em in it. this wasnt too long ago so maybe you can hunt the post and ask him about it

 

I made one out of pvc...

 

Just curious. I saw a post on here that said you can reset the truck (using some button) to a lower the preasure the the light comes on. Can you just let the air out of the tires and reset it. that way it sees zero as the tire pressure. Not sure if it would work or not.
