Polonium Pen Prevents Poisoning [
Link]
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.
Before GPS there were maps [

[Y]ou should really take a look at what ¥300,000 ($2,746) would buy you in 1981. That atrocity you see above was an actual option in Honda's Accord during Ronald Reagan's presidency, and while it didn't sync up with any satellites, it did help to guide you along in some form or another. The Electro Gyrocator, as it was so eloquently named, accepted transparencies of maps and utilized a gas gyroscope that allowed the map to move with the motion of the car and plot your progress. Once a certain map ran out of road, you just popped the next one in and kept on cruisin'.
