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 […]

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 […]

DIY LED based 3D screen

 Hackedgadgets member Alan Parekh shared an amazing build of Seekway who develped a 3D screen using 76, 000 LEDs.  If you are having a big building entrance, then you too can try to build such a huge display to put it in. If not, then still you can try some smaller builds for your room. Creating one […]

Cool Paper clip with LED

Makezine member Sean Michael Ragan shared the design of a Korean designer Sungho lee. Sungho lee’s LED light design started by cutting up some paper clips, clipping the leads on a bunch of LEDs, and soldering the one to the other.  Basically it’s a paper clip, slightly modified to to hug a watch battery and topped with the LED light.
