LED Liquid Lightbulb.
Take a tour through the world of the light-emitting diode and learn – who invented it, how to use it, and how to make your own.
Here it is! Finally, my set of 12 RGB boards showing full frame (almost) Gameboy video! (True gameboy rez is 160*144). Tech specs: * 144*144 RGB LEDs on 12 boards * 20736 LEDs in all * About 1KW power consumption on white screen * Full custom control panel designed and made by me * Ability to run 16 boards (I need 4 more) * Full 24 bit RGB supported via 30 bit PWM * All firmware, FPGA designs by me.
This is a hard drive clock I built from a 3.5" hard drive, some tri-color LEDs and a PIC16F252 microcontroller. It works by shining the LEDs underneath a platter with a slot cut into it, and by timing the various colors it can produce an analog clock display as well as other patterns
This week, Bre Pettis teams up with Mitch Altman and George Shammas to make a little 3×3x3 cube made of little LED lights that you can program with any kind of animation that you like! You can get more information and detailed instructions at makezine dot com slash podcast.
