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 […]

Iron Man with powerful LED flashlight

  You can build your own repulsor-like LED flashlight that can be mounted on your hand palm comfortably. You can turn ‘ON’ this Gadget to  produce brighter light as you move your hand back and forth. With this powerful LED flashlight mounted on your hand palm, you’ll look like an ‘Iron Man’ !!  Similar design as shared […]

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 […]

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 […]

DIY LEDs as light detectors

Embedds admin in his post has perfectly written:  “From semiconductor physics we know that semiconductor junction when exposed to light becomes more conductive. So when LED cathode is connected to +5V and anode to 0V it simply charges as capacitor.Then program switches anode pin to high Z input and read its state. Depending on time taken […]
