Trashbear Labs redesigned his nixie Sudoku to use 7-segment LEDs instead of nixies. Using 9 of these modules, a numeric keypad, an Arduino, two potentiometers and a custom case you can build a complete Sudoku board. Check schematic diagrams on the link below. [via]

Lolo’s Alarm Clock is an alarm clock project that do a lot more than wakes you up. It is build around an Arduino board and is able to keep track of time, it measures temperature, humidity, dew point, light level, air quality, and sleep patterns and wakes you up the right moment. All data is logged wirelessly to a base station connected to the computer for latter analysis. Read more about this project on the link below. [via]

This project describes how to build a portable solar charger tracker. It analyses the charging process. This unit connects with a small solar panel and a LiPo battery and keep track of solar panel voltage, battery voltage and current goes through the panel to battery charger. The design is intended for 6V panels and single cell LiPo batteries but can be adapted for any kind of panel and charger. Device is powered from batteries and uses Arduino Duemilanove. [via]
