A couple of readers weren’t too thrilled when the winners were announced a while back for the Nokia N900 competition. And to be honest, we even wondered on some ideas (like what does skateboarding have to do with hacking?) However, The teams have been hard at work and a picture video is starting to form for each. Check after the break for some video recaps.
[Thanks Matt]

Nokia team PUSH is proud to announce they have winners from the contest they held over the past two months. You may remember when we first told you about the competition, but here’s a recap. All you had to do was think of a good hack for the Nokia N900! Winners will receive funding and other resources to make their hack come alive. What possible hacks made the cut?
Haptastic – A compass and map? Not any more with this wearable guide that can lead the way.
KAPingwiththeN900 – Flying high with this aerial photography project
LIGHT HACK CREW – Bring light graffiti to the N900Rocket Pocket – Just Bonkers! An N900 in orbit, we love it!
SolderinSkaters – Tony Hawk who? It’s all about Solderin Skaters!
If you give a mouse a cookie, he will ask for a glass of milk. If you give a team of geeks a box full of parts ranging from aluminum to plywood to motors to RF interfaces, they will build a robot. Introducing Best Robotics, a volunteer group that gives schools a box of hardware and 6 weeks to build a robot that will compete against other schools for the title of champion.
This past Saturday the17th, the OKBest regional competition was held and I, HaD writer [Jakob], was lucky enough to be invited personally to not only watch – but compete. Check out our full breakdown after the jump.

The team behind the the Tweet-a-Watt/Wattcher just won first prize at the Greener Gadgets design competition. The device is a hacked Kill A Watt that transmits power consumption using an XBee. After checking out DVICE’s preview of the competitors yesterday, we’re happy to see a prototype win instead of just a concept sketch.
Capture the Flag (CTF) is a long running tradition at hacker conventions. It pits teams of security researchers against each other on the same network. Every team gets an identical virtual machine image. The VM has a set of custom written services that are known to be vulnerable. The teams work to secure their image while simultaneously exploiting services on the machines of other teams. A scoring server monitors the match as it progresses and awards points to teams for keeping their services up and also for stealing data from their competitors.
The Chaos Communication Congress in Berlin December 27-30, 2008 will host a CTF competition. Most CTF matches are done head to head in the same room. While 25C3 will have local teams, it will also be wide open for international teams to compete remotely. Remote teams will host their own images on a VPN with the other competitors. Now is a good time to register and familiarize yourself with the scoring system. It will certainly be interesting to see how this competition plays out now that teams that can’t make the trip can still compete.
Micromouse competitions have been running in Japan since 1980. In all that time, the ruleset has remained essentially unchanged. The autonomous robot mouse navigates a 16×16 maze creating a map. It then determines the optimal solution for future runs. Current records are in the six to seven second range. Teams have had to find new ways to generate traction for better times. Momoco08 uses a fan to hold the mouse to the track surface. Embedded below you’ll find a video of it solving the maze plus a photo of the vacuum skirt.
Reader [Julian von Mendel] and his team built this tennis ball fetching robot for a competition (translated). The first version used distance sensors to locate the tennis balls for pick-up, but they changed to a camera based approach. The robot has three omniwheels and is designed to calculate the shortest path to the ball despite orientation since it can rotate while traveling. The wheels are monitored using rotation sensors from PS/2 mice. The control is provided by 3 Atmel microcontrollers that communicate via SPI. The multiprocessor design is fairly generic and could be reused for a different style of robot. While their robot performed fairly well, there were some shortcomings. The limited storage space meant frequent trips to drop off balls. The tilting bucket kept them from picking up tennis balls that were against the wall. Also, the bot had to be disassembled for battery swaps. The project is very well documented and they’ve released all of their control code. You can see the robot retrieving a ball after the break.
