Word clocks are really cool. They tell the time using words. A neat thing about them is you can customize the display to show some personalized messages. Yes, TechKiwi’s new instructable is about making a personalized word clock gift, which displays the recipient’s name as well as some personalised messages such as birthday greetings. The project uses the Arduino Mega board as main controller and the DS3231 RTC chip for time-keeping.

Gilchrist’s PIP Arduino browser is an on-going project to develop a very basic and functional web browser that runs on Arduino Uno. The current version can download and render plain HTML and follow embedded links. Users can page through the hyperlinks with the help of a joystick. The project uses a 320×240 TFT LCD screen for output.

Check out this another 8x8x8 RGB LED cube controlled by Arduino. The 512 RGB LEDs are driven by 25 74HC595 shift registers using multiplexing. For those unfamiliar with LED cubes, they are simply a 3-dimensional array of LEDs that make for interesting displays. My project here is not the first RGB LED cube, nor is it the best, but I am documenting my process because while designing this cube I appreciated every resource on 8x8x8 RGB LED cubes I could find. My goals for this project were to create an 8x8x8 multicolor (RGB) LED cube cleanly. That is, with all
