For those looking for a simple and fun AVR-based project - the tinyPOV may be your solution. Based on the ATtiny2313 and after uploading the prorgram software, the tinyPOV allows you to enter the words or LED pattern to display using PC-based software, and then download it to the completed tinyPOV. Once this has occurred, you can wave your arm about displaying the effects in the air as such:
Furthermore as the tinyPOV uses the ATtiny2313, the pattern can be stored in the EEPROM - so you don't need to reprogram the whole thing every time you update the display. This then allows the use of a simple serial cable for updates and not an AVR programmer. So for more information, design details and software, visit the tinyPOV page here.

This can only be described as either something any train enthusiast would love to have, or a great annoyance to those who don't understand the fascinating with wheels on steel. Either way, it's a load of fun and would make a great project for a group as well. Kevin Fodor rose to the challenge and built his own railroad crossing (level crossing) signal with great effect. Not only are their blinking lights, he has modified a bell to sounds as well. For example:
To build your own, apart from the design story you can download a package of files from Kevin's website here. Andfor morenews, updates and items of interest.please follow us on twitter, Facebook and Google+.
When building your own prototypes or robotics projects, we have a wide range of hardware, electronics components and related items that we can deliver to you in some cases overnight. Or if electronics is new to you or a friend, consider the book "Make: Electronics" by Charles Platt - one of the best contemporary introductory electronics books on the market:
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. Andfor morenews, 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.
