[Sittiphol Phanvilai]‘s multitouch screen project was posted a couple different places today. It uses the Nokia N95 to track light pens and draws the resulting paths on the video output. We immediately saw the applications for this in laser tagging. Right now if you want to do laser tagging you need to haul a laptop with you in addition … Read the rest
Multiband Nixie VU meter
June 13, 2008 By 4 Comments
This VU meter project by [Daniel Naito] is a great piece of Russian electrocouture. It’s made up of 14 Nixie tubes that display seven frequency bands for the two audio channels. He found this similar project, but wanted to keep the cost low by avoiding such exotic ICs. First, the two input channels are amplified and then split using … Read the rest
UPCB makes your arcade stick universal
June 13, 2008 By Leave a Comment
The Universal PCB project lets you make any controller (specifically arcade sticks) console agnostic. A PIC microcontroller is used to translate between the button presses and the signals for the specific console you’re connected to. It uses a DB15 for the external plug. The PIC knows which console you’re plugged into based on which pins are high or low in … Read the rest
Wearable haptic devices bestow sixth senses
June 13, 2008 By 14 Comments
Engadget recently posted a story about a flexible tactile display that can be wrapped around any part of the body and give haptic feedback to the user. The research team from Korea’s Sungkyunkwan University that developed the device are focusing on applications like Braille for the visually impaired or transmitting tactile data to a remote user, but this is just … Read the rest
Wii Fit World of Warcraft
June 13, 2008 By 12 Comments
By now you’ve probably seen the video of two researchers from the German Research Center for Artificial Intelligence (DFKI) navigating through maps on Google Earth by using the Wii Fit Balance Board. They’ve gone even further now by using the board to navigate World of Warcraft. It’s obvious that the board is usable with any 3D environment. The … Read the rest
3 wire LCD display
June 13, 2008 By 5 Comments
Normally driving an LCD requires seven connections to pins on the display, but by using a shift register, [Phillip Warner] at Arduino Playground was able to drive an LCD using only 3 wires. The method is cheaper than a serial LCD, but you’ll mainly save yourself a lot of effort and time by using it.
[Warner] used a HEF4094 … Read the rest
Water Runner robot
June 13, 2008 By 5 Comments
Researchers at Carnegie Mellon University’s NanoRobotics Lab have developed a robot that is capable of running on the surface of a pool of water. Like their wall climbing Waalbot, the Water Runner was inspired by the abilities of a lizard, in this case, the basilisk. The team studied the motions of the basilisk and found morphological features and … Read the rest
