DIY Polonium detector makes barhopping safer

Darren Murph

Considering that Polonium has been the poison of choice in a number of high-profile cases, tinkerers who tend to spend some serious time enjoying themselves at the local pub may want to invest some time building one of these. The homegrown Polonium Pen doesn't require a whole lot of hardware -- just two darlington transistors, a LED, homemade ion chamber, one or two resistors, a battery and a power switch -- and it allows the owner to hold it over their drink and watch for it to light up. Should the LED turn on, simply pass on the beverage, exit as soon as humanly possible and figure out why in the world someone in the mob wants you to vanish. Hit the read link for the full-blown how-to guide.
