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 astronaut but it will be a horrifying an exhilarating flight. According to the spacecraft page the human payload will be in a half-sitting, half-standing position looking up through an acrylic nose dome. This first launch will not be manned, but once they get through the tests this will be one crazy ride.

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.

[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 and a beautiful (not to mention rare) PLED display complete with dramatic status messages. Check out a video of the launcher in action after the break.
