"The TinySynth is a program loaded onto an ATTiny45/85 that uses an eight-bit microcontroller to make sounds. We’ll need: TinyProgrammer, ATTiny45/85, Coin Cell Battery, Paper Speaker, Conductive Ink."

"PanoBot is a rudimentary panorama-taking device for any Canon camera running the CHDK firmware. This project was made back in ’08 so there are numerous projects that are much more full-featured than this implementation; nevertheless, I am making the code available for reference."

"Since I had 100 Pink LEDs, I decided to build something LED intensive. So, using a PIC12F629 as the microcontroller, I decided to build a Dual Die Emulator. Each die would consume 7 LEDs, so I would use 14 LEDs total for the project."

"We have a very nice Christmas-tree stand: it’s a tall, heavy, cast-iron chunk that does a wonderful job of holding our tree up. The problem is that it’s difficult to determine how much water is in the stand, or whether the tree is getting any water at all. Occasionally our tree will drop all its needles, or spontaneously combust, at which point it becomes obvious that the tree needed more water; but it’d be nice to have some earlier indicator."

"I have the Arduino Motor Shield working, the Ultrasonic module is pinging around, Christmas brought some small DC toy motors, and a bag of plastic gears is on my desk. All the good ingredients for a small robot: the Freedom Robot!"

"We have been working on a system to count the number of cups of tea and coffee made on each floor of Imagination’s offices. The #activitea project was started to better understand and illustrate hot beverage consumption at Imagination’s London offices; and to test a process that could serve many other data capture uses."

"A stepper motor turns the ultrasonic range finder 360 degrees and back. After each step the range finder is activated and the distance is measured. When two measurements have been made the PIC sends the data to the PC using an asynchronous interrupt transfer"

"The most straightforward approach to this would be to take apart an existing remote and fire its button with a microcontroller. However, that didn’t sound like much of a challenge, so instead the goal became to train the micro to output the signals itself."

"I was poking around in the JeeLabs RF12 library recently and noticed that it now supports the ATtiny microcontrollers – it’s what the new JeeNode Micro uses, which got me thinking about even smaller, simpler wireless temperature sensor modules again."
