<t>Thank you jamesh, I'll look for those books. I've been wondering about permits and all that. Didn't even think about insurance. I figured I'd wait until I was actually on the road to having parts fabricated and such before starting to process of getting permission from the gov't. I just assumed i...

<t>I've heard of SpaceX before, jamesh, sorry if I didn't make that clear. I missed the news about that launch because I was busy in school. Early December is around finals. I've also had many model rockets, mostly the little cardboard estes rockets. Please, don't think I'm uninformed or naive simpl...

<r>Burngate, thanks! I'm actually hoping the liquid thruster will use the fuel to cool the combustion chamber. I'd like to get my hands on a fairly simple engine that uses this type of cooling to see how and why it's done. Or even just renderings would be massively helpful.<br/> <br/> As for shieldi...

I've made my computer cry a few times working on Project Euler problems. They seem like they'd be a pretty good tool for teaching about computability and why you should look for ways of solving problems more efficiently.

I'm surprised nobody has mentioned Chromium OS. I'm not entirely sure of the running requirements, but it can be built for ARM architecture.

<t>As WizardOfOZ noted, weather balloons probably wont work. It was actually my first thought since I figured it'd help through the most fuel intensive part of orbital entry. I evaluated it with a relatively low weight of 200lbs. I didn't delve into it too deeply, but here's my basic train of though...

<t>/puts on black hat.<br/> <br/> You know, you could probably make one with a USB wireless connection. Set it up to occasionally ping a dynamic DNS address, put a DoS script on it, find an empty plug at various coffee houses. You could have multiple remote attack servers for about $100 each. For bo...

The original idea was that the phone would handle most of the processing, and as an added bonus would make for easy recovery if it could be made to also reenter.

<t>I have this little pet project I'm stuck on. I want to send something into orbit and have it come back. Ambitious, I know, but it's at least fun to work on. My initial inclination was to use an Arduino board interfaced with an Android phone through the mirco usb port. Would Raspberry Pi offer man...
