Dissecting the SmarTrip
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.” 
Make contributer Cy on creative uses for all that holiday trash – “Christmas, it’s inevitable, things will get discarded, broken, or ignored,” says Cy Tymony, a Torrance resident and author of Sneakier Uses for Everyday Things (the sequel to his Sneaky Uses for Everyday Things). “But why should things just go into a landfill?” In Tymony’s world, if you’ve got boxes, make boomerangs. Got milk? Make plastic.”

Gina writes “…my crafty father-in-law had built a lighting system for his kitchen pantry out of Christmas lights and a Timex watch holder. He drilled a hole in the plastic watch holder just under the tension flap that holds the watch up, and inserted a reverse switch inside the hole. Once the switch was connected to the lights, when the pantry door closes, the circuit breaks and the lights go off. When the pantry door is opened, the circuit closes and lights go on and Mom can see which can she’s plucking off the shelf.” 
Neat how-to and video from Troy…“This is my hydrogen generator that I built Using stainless steel switch plate covers. You may be asking, Why switch plate covers? Well in the area I live in I was having trouble finding Someone to sell me a sheet of stainless steel and cut it for me. So I was in the Home Depot (a local hardware store) And I ran across switch plate covers made of stainless steel. All cut to size and all uniform. Well this made it too easy for me so I bought them About 36 @ $1.24 ea. I thought it was kind of expensive but what the heck. I was not getting the generator built waiting for a deal to drop in my lap. So on to the building of the h2 generator.” Thanks Jason!
