Missile Hack Taunts Your Cat

[Atlantageek] sent in a missile launcher project that he threw together. For Christmas he received a Chumby One and a ThinkGeek USB Rocket Launcher as gifts (lucky dog). Neither of these toys are “played with” in the traditional sense as much as they become centerpieces of your next hack. In that spirit, [Atlantageek] immediately wrote a widget to control the launcher via the Chumby. The side effect of driving his cat bonkers was an unexpected bonus.

Missile Command On IPhone With Real Missiles

December 24, 2009 by 13 Comments

[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 control rather than building it themselves (especially considering it is an embedded systems class). But it is a nice build none the less. Now they need to add some imaging equipment to the rockets and they’ll be in business.

Jet Powered Hijinks

This jet powered carousel is brought to you by the Madagascar Institute. They convene, or collide, to create large scale art, sculptures, and rides. This one seems to fit the last definition. The two gentlemen are strapped to a jet powered carousel. It actually looks pretty fun, but we would have been needing some fresh shorts after the jet bursts into flames near the end. He didn’t seem too concerned, he wasn’t screaming and flailing his arms at least.

Rocket Acceleration Logger

Have you ever wondered how high or how fast a model rocket goes when you launch it? [sprite_tm] did, so he decided to build a low cost, lightweight data logger that he could fit into the nose cone of his rocket. To keep the circuit small, he built it around the popular ATtiny13 microcontroller. The microcontroller collects data from a Freescale MMA7260, a 3-axis accelerometer that he extracted from a third-party Wii nunchuck controller. After the microcontroller collects the data, it’s stored in 32K of EEPROM on a 24C256. All of this is powered by a small 3.6v Li-ion battery, which is the largest part of the circuit. If this sounds like something you’d like to make, he has detailed instructions along with the software used available on his site. While we don’t launch a lot of model rockets here, we may soon start just so that we have an excuse to build this.

Rocketting Fun

[Gabe] sent in this project summary from his rocketry club’s yearly project(pdf). The goal was to build a rocket that would go up to about 800 meters and eject a robot that would pilot itself to a destination on the ground for re use. There’s tons of great information from what hardware is in the robot to hardware design for the ejection mechanism.  There are great pictures of the final build, not so many of the construction itself. The project seemed to go well until EMI problems caused everything to fail during flight.  If you’re interested in seeing more from the club, check out their site (translated).

Model Rocket GPS And Data Logger

Serious rocket hobbyists aren’t content with merely launching their rockets into the air. [wwgd] wants to have an on board computer to control his flights and log the data.  He doesn’t quite know how to do it all yet, so he’s starting with the basics. He has built the basic GPS data logger using an accelerometer, a GPS unit, and a BS2P microcontroller. The overall weight is 62 grams and it can record for the whole 5 minute flight. At roughly $200 though, we’d be thinking twice before launching it into the stratosphere.

Rocket Camera

[Jordan] sent us his Rocket Camera project. It really isn’t much that we haven’t seen before, but we thought many of you would be feeling the effects of gravity a little harder today. So when your belly is stretched to its limits with Turbaconducken and you don’t think you can stand, take a little flight with [jordan]. Careful you don’t lose your lunch on the way back down though.
