DIY: Peltier Cooler Based Cloud Chamber

Post by Edward Miller » Tue May 11, 2010 10:14 pm

Very cool DIY cloud chamber here:
http://nothinglabs.com/cloudchamber/

"Cloud chambers let you see paths left by radioactive particles as they pass through a supersaturation of alcohol vapor. Vapor trails are formed when the radiation ionizes the alcohol.
They need to be very cold (about -15f) - so most designs require dry ice.

This design uses inexpensive electrical "Peltier" coolers instead. Unlike other peltier-based cloud chambers - it does not require ice water to operate.

See the Make a Cloud Chamber using Peltier Coolers (Instructable) for full details on making your own.

It's fairly easy to construct - and should only cost about $100 (less if you use a cheap ATX power supply)."
