Insanely Bright 60W LED Backlight for a 58″ Plasma Screen

    Ambilight, which is short for Ambient Lighting Technology, is a feature invented by Philips Electronics into their TVs that analyzes the signal and adjusts a ring of LEDs to match colors. We can build a simple “Ambilight” clone. Macetech member Garrett with his team build an Insanely Bright 60W LED Backlight for a [...]

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 [...]

DIY LED based Analog clock

Hackedgadgets member Alan Parekh shared various versions of LED based Analog clock. You can build your own analog clock using the following materials: One homemade clock uses a PIC16F877 Microcontroller with a 20MHz clock, it also has a DS1307 real time clock with battery backup. 169 x 700mcd diffused white LED’s connected in a matrix [...]

DIY LED Clock

You can build your own Atmel ATmega16 microcontroller based LED clock. The open-source softwares like interactive printed circuit board (pcb) editor and schematic capture program/tool like gschem can be chosen for your design. A Geekysuavo member shared the circuit schematic, layout and copper etch pattern. The required bill of materials can be collected from here and the [...]

Radio-controlled LED clock

A radio clock or radio-controlled clock is a clock that is synchronized by a time code bit stream transmitted by a radio transmitter connected to a time standard such as an atomic clock. You can design your own radio-controlled clock using DCF77 atomic clock. To know about DCF77, it is strongly recommended to visit the [...]

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 [...]
