The DHS "pagers" should be modified to display the DHS Threat-level color scheme to indicate the field...

Make: Online : A better Geiger-Müller mood lamp 

Übermaker Michal Zalewski is at it again:
    MAKE #21 featured a project for a Geiger-Mueller mood lamp that changed colors in response to background radioactivity. Unfortunately, this project relied on hard-to-identify and somewhat pricey components, and the color transitions seemed rather harsh. So, here's my completely different take on the same concept.

Michal's mood lamp swaps in a $20 Geiger-Müller tube in place of the mysterious $60 tube specified in the MAKE project, and utilizes a beautiful enclosure Michal made by CNCing a mold and pouring in resin. (Be sure to read Michal's amazing and definitive guerrilla guide to CNC machining and resin casting writeup if you're interested in this last step.)
