Fire Wire is a way to put on a simple but cool fire display. All you need to do is tie some steel wool to the end of some wire using a slip knot. Then using a lighter light the steel wool. Spinning the burning steel wool produces an impressive (and possibly dangerous) shower of burning metal particles.
Sean over at LED MOD has some cool LED car mod products. I would be interested to know how the RPM changing kits sense the RPM. Is there a line that goes to the spark plug or is there some sort of data connection to the car computer? However it works the results are great!
The Wii Remote has an infrared camera in the front that is normally watching for the infrared LEDs that are mounted in the sensor bar. This camera is actually quite sensitive and can be used for some cool things! Jcl5m has come up with a method that uses reflected IR light from small reflectors to provide the Minority Report style interaction. Via: Hack a Wii
The Gamerator is one heck of a gaming machine… And just think when you get thirsty all you have to do is full your mug from the center of the game system! “Introduce yourself to THE GAMERATOR … the ULTIMATE gaming machine in the world of home entertainment. Pre-loaded with 187 licensed classic arcade games … the Gamerator has everything from Tecmo Bowl to Pac Man, Street Fighter to Galaga,
Go to the DARPA Urban Challenge site to have a closer look at this years event. “The DARPA Urban Challenge is an autonomous vehicle research and development program with the goal of developing technology that will keep warfighters off the battlefield and out of harm’s way. The Urban Challenge features autonomous ground vehicles maneuvering in a mock city environment, executing simulated military supply missions while merging into moving traffic, navigating
I don’t think this engine is very efficient or reliable but sure looks like lots of fun to build. 🙂 However I wouldn’t recommend spinning a saw blade at high RPM when it is magnetically connected to a plastic CD cake box. “The Making of the Tesla CD Turbine Prototype is the story of how the Tesla CD Turbine came into being. It starts with the initial thought process
Mental note, don’t short out bus bars. 🙂 “Here arcs were intentionally initiated by bridging wires across three copper bus bars in a testing laboratory. Three phase 480 volt power was then applied across the bus bars for about 1 second. The wires immediately explode, forming a conductive plasma which forms high current power arcs between phases. The actual fault current in the demonstration is not known, but is
