Wifi Robot : A Hacked WRT54GL Rover

August 28, 2008 by 16 Comments

[Jon Bennett] sent us this link to his Wifi Robot. After playing with a Linksys WRT54GL router, he was inspired to build something that would utilize this embedded Linux system. Using a thrift store R/C truck, he built a wireless robot rover. This thing can be controlled over the internet, or by laptop with a range of about 500 meters.

The router has been modified to have 2 Serial ports and a 1GB SD Card. It connects to a micro controller, which could be an Arduino or AVR Butterfly. He has supplied information for both. The truck has been mostly gutted, leaving only the chassis and electronics. He had to beef up some of the truck electronics when they fried under the load. The entire unit is powered by a pair of 7.2 Volt 3800 mAh battery packs. The most important thing on the list though, is the horn. You can honk the horn while you are driving this thing around.

The site supplies tons of information including pictures of his build, videos of it in action, speed tests, schematics, software downloads, and resource links. Great job [Jon].

Coyote-1 Guitar Pedal Available Now

August 26, 2008 by 3 Comments


OpenStomp’s Coyote-1 is now available for $349. The guitar effects pedal lets users design and upload their own effects to the device. It has two stomp switches with LEDs, an LCD display, and four user assignable knobs. The back has 1/4″ in/out and one selectable 1/4″. It also features NTSC composite out, a headphone jack, mini-USB for uploading, and an RJ11 I2C bus for expansion. The processor is a Parallax Propeller Chip. While the OS on the pedal is open source, the hardware design and effect design software are not. You can check out the source and product manual on their forum. If you’re more interested in breadboarding hardware, you might like the Beavis Board we covered earlier.

Customers Make VoIP Calls On American Airlines Flights

August 26, 2008 by 13 Comments


Less than a week after American Airlines introduced in-flight internet, hackers have already figured out how to use the system to make VoIP calls in a few easy steps with Phweet, a Twitter application. While the network blocks most VoIP services, Phweet can connect two people using a Flash app. Aircell, the company responsible for the system, is aware of the oversight, but it remains to be seen whether this little loophole will be fixed in a timely manner. Meanwhile, we encourage those of you who do fly on American Airlines to avoid making those phone calls; your neighbor would probably appreciate it.

World Of Warcraft On A Treadmill

August 25, 2008 by 17 Comments


[Aaron Rasmussen] and his friend [Eli] slapped together this setup to see what it would be like to run as much as their World of Warcraft characters. They used a couple old treadmills to spin some tires with makeshift mouse sensors on them. As their speed increased, so did their character. There was a decent amount of math done to figure the average speed of a World of Warcraft character, and ultimately they settled on 12 miles per hour. Not surprisingly, they found that too difficult due to the resistance in the rig as well as being out of shape. They ended up lowering the speed required to make their character go full sprint to 6 miles per hour.

Their final conclusion was that they could never run as much as their digital counterparts. Even if they were in really good shape. [Aaron] does say that it was fun enough to consider doing it regularly as a workout plan. He should wear the costume every time he uses it.

Tongue Drive System Turns Mouth Into Virtual Keyboard

August 25, 2008 by 11 Comments


Researchers at Georgia Tech are working on a Tongue Drive System, which transforms the tongue into a tool that can manipulate computers and manage appliances and wheelchairs. This project has huge implications for the disabled, especially for those with few motor skills and limited movement. Many disabled Americans are paralyzed from the neck down, and this system could be a literal lifesaver, providing them with a method of communication and control over their own lives. Scientists have been attracted to the tongue’s potential for a long time. It provides several advantages over using other organs or appendages. It’s very sensitive, tactile, is not connected to the spinal cord, and does not usually end up being harmed in accidents. By placing a tiny magnet underneath the tongue, it’s transformed into a virtual keyboard. Sensors placed in the cheek track the magnet’s movement and processes the commands into directions for electronics, be it a wheelchair or a home appliance. We’re excited to see where this will go.

Improved Jog Wheel

August 24, 2008 by 1 Comment


Taking a cue from the jog wheel we posted last week, [42ndOddity] has built an improved version. The design is based around a solid state rotary encoder instead of an optical encoder. The rotary encoder is far easier to attach and position properly. The knob is milled from scrap aluminum-it was a copier foot. To make the motion smooth, it’s sitting in a bearing from the same copier.
