How-To: Mount a video camera in a model rocket
James Yawn’s site Recrystallized Rocketry has lots of great information about DIY rocketry, including this great tutorial about mounting a video camera. This hot pink rocket is called the “sugar rush,” because it is powered by Yawn’s homemade potassium nitrate/sugar rocket fuel. [Thanks, Kenneth!]
Rocket fuel from aluminum and ice
The key to the process is that the metallic aluminum is present as a nano-scale powder, and its oxidation by water thus occurs over a huge surface area and therefore proceeds very quickly, releasing amazing amounts of energy. The video starts with the acoustic mixing of the nano-aluminum with water to make a gray paste which is frozen, in a mold, to make a tubular rocket motor. It then proceeds through various test-bench firings and culminates (at 4:00) in the launch of an actual rocket using the mixture.

DIY bike repair stand
Sometimes our bikes break, and when they do it’s a lot easier to repair them if you have a stand. Too expensive? Then make you own bicycle repair stand with a few parts form the hardware store.
VR bike ride through Google Street View
Maker Aki Mimoto wrote in to let us know about his exciting new Arduino/VR/Web app mashup. He’s wired up his wife’s bike on a stationary platform to an Arduino using a reed sensor. Using the sensor data from the bike, along with data from a head mounted display (HMD), Ari is able to accurately pinpoint his position within Google Street View.
