How to build a ping-pong ball display

January 31, 2011 By 40 Comments

If you’ve been lusting after your own glowing display we’re here to help by sharing some simple building techniques that will result in an interesting project like the one you see above. This is a super-accurate clock That uses ping-pong balls as diffusers for LEDs, but with a little know-how you can turn this into a full marquee display. Join … Read the rest

Color clock makes telling time impossible

June 7, 2010 By 22 Comments

[Bogdan] set out to build the all-too-familiar binary clock. But, he didn’t want to be ordinary, and set the goal of making the clock as hard to read as possible. What he ended up with is a clock that is almost impossible to read correctly.
He’s using colors to tell the time. We immediately thought this might make use of

Clock hides time until you’re in close proximity

April 15, 2010 By 10 Comments

[Alan] is branching out beyond the Arduino with this clock. He’s still using the same code but built this board around an ATmega328 and the components he needed, saving his Arduino board for further development. The concept uses a character display housed in an old iPod Touch case. The build relies on an infrared sensor to actuate the LCD … Read the rest

Binary clock uses DS3232 RTC

February 17, 2010 By 24 Comments

[Kenneth Finnegan] quenches our clock-a-day compulsion with his Arduino based binary timepiece. The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232 real-time clock which automatically compensates for temperature to achieve very accurate time keeping. We like the super-cap circuit he added to keep the RTC running if the … Read the rest
