[Travis] sent in his oh so simple(why didn’t I think of that) syringe logic probe. that he put together for his version of the sump logic analyzer. Real probes tend to be pretty expensive. With some effort, you can probably fit an led/diode/resistor in there and make a simple 5v logic probe. If you’d like a nice logic analyzer, Spartan-3 board that it’s based on is only $99.
As purveyors of a fine hacks, we often get pitched on what are generally considered very bad ideas. Luckily, most of these ideas die on the drawing board due to a lack of time and energy or maybe having a shred of moral accountability. There’s nothing that government funding can’t fix though. Popular Science has put together a gallery of The World’s Spookiest Weapons. It’s a who’s who of real and speculative engineering that could lead to our eventual destruction. Opening with the atomic bomb, it moves quickly into more bizarre territory, everything from heat rays, to rail guns, to gassing people with elephant tranquilizers. Our personal favorite is The Rods from God. Imagine getting smote by a precisely targeted metal power pole dropped from space that has accelerated to 36,000 feet per second thanks solely to gravity. What a wondrous world we live in.
