Another digital clock displays Game of Life

Matthew wanted to makes geeky gift for his brother who is mathematician and programmer. So he came out with digital clock idea which would display time and play Game of Life. There are plenty of Game of Life clocks around the internet bu all seemed somewhat limited in display size. So he grabbed 16×32 RGB LED matrix and built pretty slick looking clock. The clock is build around Arduino UNO which reads time from Chronodot RTC. Clocks display is refreshed every minute and game of life start over where time digits act as initial condition. Likewise other clocks, this one always displays time in background, so anytime you could tell the time. Again – Arduino UNO has limited RAM so there has to be various optimizations and workaround made. Other clock options include: brightness control, UTC offset, LIFe game speed, 12/24 hour mode select, changing colors of display. Continue reading

Have a Brand New Experience with Weather Canvas!

Mother Nature is always full with many unexpected surprises. That is why some people enjoy the outdoor activities, such as hiking, trekking, kayaking and so on, rather than staying at home in weekend! The only matter is weather is constantly change and unpredictable. Maybe it full with sunshine in the morning, but it rains heavily in the afternoon! It will cause some difficulty, especially for those who planning to have some outdoor activities. In this case, you might need an assistant to help you overcome the matter. Well, Weather Canvas is coming for the rescue! A little bit different from other DIY weather station, Weather Canvas is a outdoor wireless weather monitoring system coupled with an indoor LED display. For your information, the outdoor system consists of a microcontroller, temperature sensor, humidity sensor, self-DIY anemometer, a Hot Wheels radar gun (It’s for measuring precipitation) and a solar panel to measure sunlight, also charge the microcontroller’s power source! This is how the Weather Canvas works: In the very beginning, the system is transmitting the data it has collected to the indoor… Continue reading
