Open-source Mars rover

[Seth King] wasn’t satisfied with current robotics platforms that don’t work well outdoors. He started the Open Rover Kickstarter with the end goal of having a 6-wheel robot with a rocker-bogie suspension just like the Mars landers. We’re sure it’ll be an interesting platform.

Adding a Flash to a key fob video camera

[doctormord] picked up a key fob “spycam” and was surprised that there wasn’t any onboard illumination. Then again, that would probably defeat the purpose of the “spycam.” A transistor, LED and resistor later (translation), he had a camera with a light. Pics here.

Automated WEP cracking

This is a video of [Elliott] using his autocrack script to crack a WEP wi-fi network. It took [Elliott] less than a minute to crack a network he set up. Lesson: don’t use WEP.

Adding wi-fi to a laptop the fast way

This laptop used to have a broken Mini-PCIe wi-fi adapter. [Mikko] fixed the wireless by taking out the old card and hooking up a USB wi-fi adapter. He soldered the USB leads directly to the back of an internal USB port and used hot glue “to prevent bad things from happening.” A very easy, fast, and cheap way of fixing a broken wireless adapter.

Han Solo’s soldering iron

When [Craig] was 15, he broke the Bakelite casing of his father’s soldering iron. Being a good son, he fixed it by gutting his original Star Wars Han Solo blaster. Nice, but not as great as Starsong from My Little Pony.

All terrain Roomba

This little rover gets around on rough terrain pretty well. [Dean Segovis] built it using parts from a Roomba. The Roomba uses wheels in conjunction with gearboxes that handle a lot of the dirty work in getting this prototype going. [Dean] grabbed four of them, as well as the motor controller board and batter, and installed them on this Rocker-bogie suspension. In the video after the break he mentions that this would be quite a good climber if the batter were relocated to the center of the body. An ultrasonic sensor adds obstacle avoidance with and Arduino taking care of the processing. We can’t wait to see future versions of the Roomba’s rough-and-tumble outdoor cousin.
