Hackers Age 14-18 Can Compete To Put Their Project Into Space

If you’re between the ages of 14 and 18, or have a child who is, here’s a chance to put a project into space. NASA is partnering with YouTube, Lenovo, and a few other entities for a contest that challenges participants to dream up low-gravity experiments. You can enter as an individual or in teams of up to three people, and may put forth up to three experiment ideas for judging. Getting in on the first round is as easy as recording and uploading a video. You’ll need to state a scientific question or principle you want to test, a hypothesis of what can be learned, and a method for testing it.

As with most of the projects we encounter, the seminal idea is always the toughest part. And since the folks here at Hackaday are too old to enter, we thought we’d propose throwing around some ideas in the comments to get the ball rolling (the contest FAQ says it’s okay to get help from others so we’re not ruining it for everyone). We’ll go first.

It looks like experiments can be Biology or Physics related, and can’t use hazardous chemicals, weapons, or anything sharp. We’d love to see some tests that measure how well electronic sensors work in the microgravity. For instance, can you use a gyroscope sensor reliably in micro-gravity? What about an electronic compass; does it always point toward earth? What about robotic propulsion? We’d love to see a minature ROV swimming through the air like a water-bourne vessel would on earth.

Your turn. Leave a comment to let us know what you’d do if you could enter. Oh, and we’ve also embedded the contest promo video after the break.

An Autonomous Minivan For Busy Parents

Although minivans are a staple of moms and dads that drive their kids to school, soccer practice, and the like, this vehicle imagines a time when maybe they won’t even have to. Autonomous cars have been in development for some time, but the video after the break gives a nice close-up view of how this particular vehicle was built and some of the testing that went into it.

Of particular interest was the external luggage pod modified to hold vehicle electronics. Everything is nicely laid out with wire duct to keep it neat. Those in the manufacturing industry might notice several other off-the-shelf components including an area scanner at 0:24 and extruded aluminum framing at 0:45. The apparent “E-stop” button on the passenger side comes from industry as well and may make the rider feel a bit more safe!

If this wasn’t interesting enough, check out this autonomous car by Google that has already driven from San Francisco to Los Angeles!

Candied LEDs Are A Light, Tasty Treat


[Emily Daniels] recently snagged a free iPad in the Instructables “Play with your food challenge” with an interesting way to work with LEDs. Growing up, most kids attempted to make, or at least have seen rock candy be produced. [Emily] thought it would be interesting to mix LEDs with the stuff to see what she could come up with, and her candied LEDs are the result.

The process is pretty straightforward, and involves mixing up a batch of supersaturated sugar syrup in which LEDs are suspended. The LEDs act as a nucleation point for the crystal formation, growing a nice solid coating of sugar after a couple weeks’ time. After some cleaning up, the LEDs can be connected to a coin cell battery or similar, as you would normally do. The sugar acts as a diffusing medium for the LEDs, giving them a nice soft beam pattern.

Obviously you likely wouldn’t want to use these for any long-term electronics project, but it’s a fun activity for the kids, and it could be a good way to incorporate electronics into baked goods.
