Geek’s Radiation Monitor


Small enough to put on a keychain, the Nukalert is a 24/7 Radiation Monitor and Alarm. With terrorists and rogue nations now threatening to unleash nuclear devestation on an almost daily basis, it seems an appropriate time to take some precautions.

The Nukalert detects Gamma and X-ray radiation 40keV to 2 MeV, and indicates repeating groups of rapid countable chips. A faint clicking indicates all is OK. An audible alarm approximating 61dBA (speaking volume) sounds when radiation is detected. The unit is powered by a battery which lasts 10-15 years (non-alarming), or as little as 3 months when alarming continiously at highest alarm level. I’m just guessing, but I assume this 3 month period would be sufficient to outlive the unlucky owner in such a situation.

The Nukalert is priced at $160.00 USD each or $145.00 each for 2 or more, and is available from their website

Build Your Own Web Based GPS Tracking System


I ran across an article describing how to build a web based GPS tracking system. It’s a project that many fellow geeks will probably enjoy.

Briefly, you build a simple mobile GPS tracking system from a laptop and have the data delivered right to your own computer. With the addition of a Web server—and a Google Maps client-side JavaScript—you’ll be able to see the data via the Web on an interactive map.

The complete article is available on the GeoPlace website
