Transmit data via enviromental lighting

LVX systems is developing a system using led lighting to connect to the internet. modulation is done at frequencies that are imperceptible to humans. Will moths be the first biological organism to catch a computer virus? Via Geek.com

Scrolling marquee from Christmas lights

John repurposed GE Christmas lights into scrolling marquee. Via Hack a Day.

RGB LED flower

This LED flower is controlled by AVR with software USB stack. It contains 6 RGB LEDs which are at the end of twisted enamelled copper wires. Project is well documented with extensive tutorial. Via mcu.cz

App Note: LEDs allow new remote-controlled lighting applications

A remote-controlled lightning applications: One benefit LEDs offer in general lighting applications is that they are easier to control remotely. This application note describes a remote-controlled architectural or street-lighting system and describes how to implement power-line or wireless communications control of a lighting system. Thanks for the tip rsdio!

Star map: A breathtaking piece of sky

MrTrick made a star map: Now that Christmas is over, most of us have gone back to work, and the decorations are being packed away, the fake Christmas tree is likely to use up the most space in storage, and you only use it once a year! It’s a shame to throw it away, but […]

Minimalistic LED dice

This dice by Rickard Gunee is interesting because it uses one of the smallest microcontrollers, a 6-pin PIC10F200. With 4 GPIO it’s just one pin more than the voltage regulator. Using multiplexing it controls 4 strings of LEDs and even one input button. The whole project is open source and also available as kit.

Led Cube 8x8x8

chrmoe built this 8x8x8 Led Cube 3-dimensional LED display. Via Hack a Day!

3D LED cube thing

MichaelZ spotted a commercial 3D LED cube. I saw this at a home construction materials show in Taiwan 3D LED cube thing In person they are very impressive. There are vertical strips of SMD LEDs and the light changes color. Amongst patterns they can sort of swirl around like a cloud or school of fish. […]

Christmas lights as a chat list indicator

Andrejk uses an individually-controllable Christmas lights to indicate the presence of someone on his IM contact list. Via Hack a Day.

Christmas message display project

Embedded lab has designed a Christmas message board using the PIC 16F688, an old printer power supply, BC547 transistors and LEDs.

Hacking RGB Christmas lights

Deep Darc has successfully reverse engineered the operation of a 50-light set of GE multicolor Christmas lights. His work involved snooping the protocol used on the LEDs data bus line and exploration of the remote control unit, resulting in source code allowing control of the display of colors and patterns by an Attiny13A.
