Amateur radio operator WA5ZNU has used an Arduino and a colour LCD shield to build a "Waterfall display" unit. These are used by radio operators to plot signal strength and frequency against time on a scrolling display. According to the...
For an interesting mixture of technologies and development systems that span almost thirty years, this project has to be winner. "dooglehead8" on YouTube has used the Texas Instruments EZ430 Chronos wireless development watch to send accelerometer data back to a...
Christopher Monaco's girlfriend asked him for a better way to view her iPod display while driving - and he devised a great solution using a large LCD, custom hardware and the PodBreakout system. The resulting control device can display song...
Using a Texas Instruments TI-83+ calculator, some custom software and hardware - and a floppy disk drive, the people at Cemetech have created what can be described as a very loud and different way of playing tunes. The media player...
Dave Clausen from the NYC Resistor space built an amazing RGB LED cylinder that not only looks amazing, but also must have been a true feat of hand-soldering. The display comprises ninety-five RGB LEDs, which are soldered to solid music...
Using an Lilypad Arduino as the brains, 'jnorby' has constructed and documented an amazing diaper purse. In her words: Design and technology merge to create a twice-functional diaper bag that will serve to illustrate useful reminders on what's missing and...
With only an Atmel ATtiny85 microcontroller, some flat piezo elements and a coin cell battery you have enough electronics to create sounds and play a tune similar to those in a musical greeting card. The tune to play originates from...
Electronics enthusiast Fabien Royer was concerned about the level of radioactivity being published by the Government after the recent incidents in Japan, and therefore decided to construct his own geiger counter that could also report the data over twitter for...
Although using an Ethernet shield with your Arduino to send tweets is convenient and allows autonomous tweeting without a host PC, to save money Iain Foulds has described a method for an Arduino to send tweets by instead using an...
