Freeside Atlanta makes space for local hackers click to enlarge At a regular Tuesday night meeting of Freeside Atlanta, there's talk of building a RepRap machine. A RepRap, treasurer Raiford Storey explains, is a prototyping device that can make its own parts. Once one's built, it can be used to create another and another and so on. Thousands of machines could be made, replicating one another like a hive of robotic insects gestating inside Freeside's Metropolitan Warehouses space. A 2006 Guardian article suggested the RepRap might "bring down global capitalism, start a second industrial revolution and save the environment."

DIY Taser +30,000V Ever wondered how fun it would be to zap someone with a taser? Now you can. :DIf you follow the instructions you should be able to get a good shock out of this that not to lethal but I'm sure its not that hard to step this up from a good shock to a powerful weapon so be responsible with this and use common sense when choosing who to shock (don't go around shocking old people, small children or any one with a heart condition its just a bad idea). Now that thats out of the way the taser we will be building sends out about one shock per second probable around 35,000-40,000+ volts at an estimated .01 milliamp (millionth of an amp) the shock is about enough to cause you to jump back a few feet if your not expecting it. Voltage and amperage are estimated since i don't have the equipment to accurately measure it. P.S. sorry about the low quality pictures and bad lighting my good camera was KIA I'm working on getting a replacement camera to take better pictures
Outerzone : Bellanca Decathlon plan : download free vintage model aircraft plan Plan file details:Pilot Bellana Decathlon - Radio control large scale model. Quote: - "This big brother of the Pilot Citabria 20, this is a huge bird for 10 to 30 ccm engines, gasoline engine capable...so if you had a big hangar and love big scale birds, this model is for you. Enjoy it!..." IRremote Library, Send & Receive Infrared Remote Control IRremote, by Ken Shirriff, allows you to receive or transmit Infrared Remote Control codes. You can make your projects controlled by a remote, or make them control other devices like televisions and stereo components. Download: IRremote.zip(modified to work on Teensy and other boards) Hardware Requirements For transmitting, a single Infrared LED and resistor are needed. For receiving, an IR receiver module with internal bandpass filter is needed.
Why hack a calculator? Why climb Mount Everest? So you're a programmer deciding where to invest your energy. What's a better idea: the latest Apple device, where hot new games can mean big bucks and millions of users, or a calculator introduced 10 years ago? Most go for iPhones and iPods. But another community thrives in its own way.
rocketstoves - www.ErnieAndErica.info Ianto Evans, Leslie Jackson, Ernie Wisner, Kirk Mobert, Paul Wheaton, and other friends are among the researchers developing efficient, clean-burning, affordable stoves for a variety of heating and cooking needs. This group developed and published the current editions of Rocket Mass Heater, or Rocket Masonry Stove, designs. The technology combines an innovative clean-burning combustion chamber, with an earthen masonry thermal mass, resulting in extraordinary heat capture and low waste from an incredibly small amount of wood.

Cheng Yang Model Factory Item No: CY8008 Wingspan: 2450 mm (96.4 in) Wingarea: 87.3 dm2 (1354 sq.in) Length: 1890 mm (74.5 in) A Multi-Protocol Infrared Remote Library for the Arduino Do you want to control your Arduino with an IR remote? Do you want to use your Arduino to control your stereo or other devices? This IR remote library lets you both send and receive IR remote codes in multiple protocols. It supports NEC, Sony SIRC, Philips RC5, Philips RC6, and raw protocols. If you want additional protocols, they are straightforward to add. The library can even be used to record codes from your remote and re-transmit them, as a minimal universal remote.
