E-reader Becomes Sailplane And Paraglider Computer

sail [Tweepy] flies unpowered aircraft, and he’d like to use the XCSoar flight computer app for gliders, sailplanes, and paragliders, but couldn’t find any hardware. XCSoar is an amazing app that can keep track of terrain, route, thermals, and a whole bunch of other variables that make flying more enjoyable, but running it on a device useful for a hang glider pilot is a challenge.

He eventually found a nearly perfect device in the Kobo mini e-reader. It’s e-ink, so it’s sunlight readable, uses a glove-compatible resistive touchscreen, runs Android, and is dirt cheap. The only thing lacking was a GPS receiver. What was [Tweepy] to do? Mod an e-reader, of course.

The electronic portion of the mod was simple enough; serial GPS units can be found just about everywhere, and the Kobo has a serial headers on the board. The case, however, required a bit of thingiverseing, and the completed case mod looks fairly professional.

With a few software updates, new maps, and of course the phenomenal XCSoar app, [Tweepy] had an awesome flight computer for under 100 Euro. The only thing missing is an integrated variometer, but a Game Boy will work in a pinch.

Arduinos…. In…. Spaaaaaace…..

Since 2007, [Adam Kemp] has been leading a team of students from Thomas Jefferson High School, guiding them through the process of designing and building a small satellite that NASA selected for launch early next year.

The CubeSat, officially named TJ³Sat, uses commercial, off-the-shelf components for nearly all its systems. The team ran into a problem interfacing the FM430 Flight Module (PDF warning), so [Adam] designed an Arduino-based replacement. Based on an ATMEGA328, the entire board is a drop-in replacement for the FM430 Flight Module. On July 1st, the TJ³Sat will begin testing at Orbital Sciences Corp. to make sure the entire satellite is up to snuff.

The TJ³Sat’s payload will take data from the ground controllers and using a TextSpeak module convert serial data into spoken voice. This audio will then be transmitted over amateur radio frequencies and will be picked up by hams all over the world. We’d like to wish the students at Thomas Jefferson High a hearty congratulations for being the first High School to build a satellite and hope the testing and launch go as planned.
