Edison’s Cradle is a bright idea

This interesting take on Newton’s Cradle is called “Asobi” and was created by [Yasutoki Kariya]. However, [Johnny] at Spoon and Tamago dubbed it “Edison’s Cradle”, which we think is a great name.

As you can make out in the video, it isn’t really a Newton’s Cradle. There is a solenoid pushing the bulbs at the end out at the correct time, but that’s fine. The overall result is quite brilliant. Unfortunately, we don’t know much about the setup. Anyone have more information? Anyone want to take a stab at making “Tesla’s cradle”?

Controllable LEDs spice up the living room

[Sprite_tm] brings us another great hack by lighting up the living room. Unsatisfied with just replacing incandescent bulbs with an LED alternative he went with strips of LEDs to illuminate the length of a wall. Starting with a seven-meter strip of the lights, he cut it down to fourteen pieces in order to make the RGB devices individually controllable. [Sprite_tm] whipped up a design for controller boards using RS-485 to communicate with each, and sourcing an ATtiny2313 for the PWM necessary to generate any color. As you can see in the video above, the finished project is brilliant. Oh, and the Lounge Music as a background is nice too.
