DIY AVR-based Egg Timer
AVR enthusiast Kio has described a stylish and useful digital egg timer based around an ATtiny2313. What makes this different is the use of the low-power mode of the AVR as the speed is down to 1MHz. Furthermore the use of a rotary encoder for user input is nicer than a group of simple buttons. For example:
Finally Kio has not only published the project code, there is also full schematics, PCB design files and detailed notes - enough to get you virrtually manufacturing your own versions. And for more news, updates and items of interest.please follow us on twitter, Facebook and Google+.
To get started with your own egg timer or other related project, we have a range of electronics components from various distributors including Sparkfun, Seeedstudio and Electus - and can get them to you in a flash. One component of interest is the illuminated rotary encoder - which contains an RGB LED in the shaft. This allows all sorts of user feedback or mode display as well as data entry all in the once device - very clever.
