Fresh hacks every day
[Craig Turner] wrote in to tell us about the wireless fireworks controller he just finished building. It has eight total channels and offers the kind of safety features we like to see when working with explosives. The image above details the launcher side of the project. The project box houses an Arduino which is powered by a 9V battery. To enable this base station the key lying on top of the … [Read more...]
http://www.youtube.com/watch?v=svzXxuQIKlc&feature=player_embedded There isn't a hacker out there that isn't interested at least a little bit in the prospect of building a mission specific rocket to explode someone off the face of the planet... without killing them. We got a tiny taste of what is coming when they let us watch their engine test a few weeks ago. Tomorrow, May 19th, they are … [Read more...]
The Copenhagen Suborbitals are now within one week of their first launch. We looked in on the non-profit and non-secretive space program back in March but we had no idea the group had a frickin' submarine at their disposal. What you see above is the rocket on its floating launch platform. The submarine will haul it out into the Baltic Sea for launch. There's not much room in the craft for an … [Read more...]
[Jeff] and his team completed this iPhone controlled rocket launcher as part of their final project at Georgia Tech. Two servos provide the rotation referenced by an onboard electronic compass, and elevation control for launch. These are interfaced with an eBox 2300 using a few Phidgets boards. Check out the launch video below. It's too bad that they went with a commercial solution for servo … [Read more...]
[Josef Jahn] has posted a detailed guide on building a microcontroller-based launch box. Constructed from an Atmel ATMega168 and powered by a 12V rechargable lead gel battery, the launch box is fully portable and includes a number of safety features. Going the extra mile on what could essentially be a simple push button launcher, he added three safety switches, a sixty second after-launch timer … [Read more...]
