The guys over at Hak5 have created a fun Graffiti Wall, this wall takes entries from the web and projects them on a huge display on their wall. The text display is just the beginning, games are planned in the future! Give the wall a try! Have a look at the code that makes it tick. "Hey guys, this is the code I whipped together to make the Hak5
These microcontroller based fireflies are cool. At first I thought they simply started to flash when the lights turned off but they actually are able to detect the flashes of their neighbors and sync themselves! "What can be observed is that the fireflies start with random blinking. But as time goes by, they are able to slowly synchronize with their nearest neighbors. And these neighbors are synchronizing themselfes with
If you are looking for a product that keeps you safe while in your car this In-Vehicle Blind Spot Detection System is sure to help. Download project. "In the presence of any approaching vehicle these high intensity pulsed beams get reflected back to the vehicle and is detected by Infrared sensor TSOP 1738.Whereas in the absence of any approaching vehicle no reflected Infrared beam is present and output of
Yes, same prize as last week… Seems like lots of people like a good small flashlight. This contest will run for one week (Aug 9 – Aug 15, 2008) . Ending time is based on central standard time.

Trossen Robotics just completed their latest project contest, the Xr-B3 didn’t win but it is a very cool creation! "He is powered by an AVR ATMEGA324P micro controller on a custom board that I made. He is using an XBEE module to communicate with my PC (and eventually with other robots). Onboard sensory includes: 2 Sharp IR sensors (for wall following and obstacle detection), an SRF-05 sonar sensor and
Setup your digital camera on a tripod, turn off the lights and get out your favorite laser pointer to make some brilliant pictures! It does take some practice to make a good image but when it works the results are great. Thanks to Laura from China for sharing. 🙂 "How to use a laser pointer to draw, to write and to record it? I think it is a very
Steve Norris from Norris Labs has created one of the most interesting clocks I have seen in a long time. This clock would make watching the time go by very enjoyable. "Stonehenge uses a CrustCrawler Smart Arm and a Parallax Propeller chip to display the current time. All the digits needed to display the time are located on cards positioned in a semi-circle around the left and right sides
