This project is a really simple accelerometer based altimeter. The assembled board only weighs 10grams; the power supply is an additional 6grams. The data collection is done by a Basic Stamp II. It records 1 second before and 11 seconds after it detects the initial launch thrust. On their first launch they got some legitimate looking data (it would have been nice if they had an inclinometer to compare it to). The second launch resulted in a catastrophic engine failure on the pad. It’s a shame they couldn’t do more testing, but at least they’ve got video. Schematics and source code natch.

The folks over at Remote-Exploit were recently dropped from Google Adsense and need funding. Why should you be concerned? They’ve recently rolled the excellent Auditor and WHAX live cds into a new distro called Backtrack. Why am I concerned? The were dropped for “Hacking/cracking content”. [thanks Michael Schade]
