HOW TO – The Super POV




Here’s how to disassemble a DC WMATA’s SmarTrip card and turn it into a keychain-ready size –“The SmartTrip card is composed of three sheets of laminated cardboard (or plastic; it’s tough to tell). The middle one is where the important guts are located. The outer two serve a decorative and protective function. The first order of business is to remove those outer layers. But before you do, resign yourself to destroying the card. You might be able to transplant its brain into a new body, but DCist doesn’t want any angry emails demanding money for replacement cards.” Link.
Nice bike – “What does a propulsion engineer do when he wants to experience the power of a rocket without going to space? He simply bolts one to a bike. How It Works – 1. A toggle switch on the battery pack arms the ignition system. 2. The left-thumb button sends power from the battery pack to an igniter on a model-rocket motor inside the rocket engine, vaporizing the roofing-tar fuel so it can burn. 3. The right-thumb button keeps the nitrous oxide flowing (and the rocket lit) as long as it’s pushed. 4. The left brake lever regulates the flow of nitrous and throttles the rocket.” Link.
