DIY Pocket binary Alarm Clock

Binary Alarm Clock provides an original and innovative method of displaying the accurate time. Instructables member linux-dude shared his compact binary alarm clock that uses an Arduino Duemilanove (which fits perfectly in the tin) to keep time and control the indicator LEDs. The LEDs are arranged in two rows as you would expect, representing hours and […]

Wine-O-Meter – Carnival-Style Breathalyzer

Expecting plenty of drunken revelry, Substatica’s member Phil constructed the Arduino Wine-o-Meter – a carnival “Test your strength” style breathalyzer.  The 25 Shiftbrite modules are lined up in a column, which is connected to an Arduino tucked away in a cardboard box and are powered by a 4.5volt 500mA adapter. The Arduino takes readings from an […]

512 RGB pixels based LED panel

Adafruit brings out 512 bright RGB LEDs based panels arranged in a 16X32 grids fashion.  This product is superb product to be used to display animations or short video clips. These displays are designed to be driven by FPGA, CPLD, Propeller, XMOS or other high speed multi-processor controller. The good news is that the display […]

Voltage-controlled RGB generator

Enide member shared an amazing project of designing one simple RGB color generator. With the power of PIC12F675 microcontroller you too can build your own circuit that generates many colors using a RGB LED. The basic concept of the project can be viewed here. The working principle that governs this project is : “Two independent […]

The world’s most efficient flexible OLEDs on plastic

Researchers in the University of Toronto’s Department of Materials Science & Engineering have developed the world’s most efficient organic light-emitting diodes (OLEDs) on plastic. This result enables a flexible form factor, not to mention a less costly, alternative to traditional OLED manufacturing, which currently relies on rigid glass. “This discovery, unlocks the full potential of […]

Motion triggered LED matrix display

If you are planning to implement any electronic moving display system that is activated by movements in its surroundings then just have a look on the project posted by Jer from Volts and Bytes, where an Atmega8 is used to activate a Sure Electronics 0832 LED matrix display when motion is detected by the attached PIR sensor. Check the link […]
