Fresh hacks every day
[cmwslw] built a soda-bottle water rocket that uses the ignition of oxyhydrogen gas to quickly expel the water, as opposed to the usual compressed air and water mixture. His project contains excellent documentation with photos and it builds on other articles he’s written about generating the flammable HHO gas used to launch his craft into the skies. Every aspect of … Read the rest
[Stephan Jones] has an easy method for making your own model rocket engine igniter. The solid state motors used in this hobby consume one igniter with each electrically triggered launch. Whether you’re making your own motors or not, this construction technique should prohibit you from every buying an igniter again. The process involves bending some nichrome wire around a … Read the rest
Sugar rocket
We’re told that this rocket is sugar powered. It’s quite a bit bigger than the homemade sugar motors we saw last week and it makes for quite a show. [Thanks Estqwerty]
Wooden PC construction
The finished look of this wooden PC case seems very familiar to us but we’re not sure we’ve seen pictures of the build process… Read the rest
[KoD] and [Navic] are building solid propellant motors using sugar and potassium nitrate. They cook up the two ingredients along with water and a bonding agent. They find that corn syrup is particularly good for bonding and that cooking the strange brew is more of an artform than science. Either way, the video after the break is proof of the … Read the rest
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 … Read the rest
Hackers [Navic] and [K.o.D] have fitted an Arduino Pro Mini and an array of components into an off the shelf rocketry kit to create a guided model rocket, taking the whole idea of Arduino-based space technology to another level
The Arduino reads signals from internally mounted accelerometers, and adjusts balsa fins (via 4 micro servos) to correct the rocket’s … Read the rest
[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 … Read the rest
