Here we have Arduino Forum contributor Marklar sharing his intense Arduino-based RGB LED home lighting scheme, which uses an old stereo front panel to control the different chase patterns within the crown moulding of his living room. The intensity and color of the lights can be manually controlled with the stereo’s rotary encoder to suit […]
Based on The Awesome Button, Les made a one step boss dialer by hooking an emergency button into his employer’s IP telephone system. Inside the button is a Teensy board, which connects to his computer via USB. A C# app on his computer listens for the pause/break key from the Teensy and makes an HTTP […]
Jonathan Stark, author of Building iPhone Apps with HTML, CSS, and JavaScript, has not only posted his Starbucks card for all to see, but he’s using it to conduct an interesting experiment in social sharing.
Twinkle toes! Make LED ruffles to customize your shoes in this CRAFT video. This easy soft circuit project can get you started in wearable electronics and even may help you find your way in a dark parking lot.
Need more digital outputs on your Arduino? Check out the EZ-Expander Shield from the Maker Shed! Using the two 74HC595 shift registers, you can add up to 16 new output pins (numbered 20-35.) The shield itself uses 3 existing Arduino pins to operate (pins 8, 12, and 13), so overall you get 13 additional output pins to use.
David Dorhout of Ames, IA, wrote in with his very cool robot, Nuntius the Garden Avenger. Love the controller! A couple of years ago I first saw one of those self contained game systems that consist of just the joystick and the AV wires that you plug into your TV. I was simply amazed at […]
OK, in point of fact, this cool gadget from Matt Bitz of Liquidware could be used for pretty much any type of marksmanship training, but “sniper” was a pretty hard headline to resist. It couples Liquidware’s TouchShield Slide, an Arduino Duemilanove, and a lithium battery-pack in a camouflaged aluminum case for a handy range-gadget that records hits on a target—just tap the touchscreen with the tip of a round to mark a hit—and calculates accuracy and precision in real time. [Thanks, Jake!]
