Curb Office Productivity With Expensive LED Wall

Hero-Design wants you to make art at work with this mesmerizing contraption and as far as we’re concerned they hit the nail right on the head with the inclusion of LEDs, we’re whores for LEDs. The team over at Hero have come up with an interactive wall of 464 pixels that can be individually controlled to display any of the available colors simply by turning the circular pixel in either direction.

The design is quite elegant with a luxurious color scheme of black on black on black. Until you touch a knob or play an animation, that is. The large wall unit comes with a custom designed animation of your choice along with three other animations (and hopefully instructions to create your own animation from scratch). They have taken some precautions that we’re pleased to see: each pixel has redundant LEDs in the case that one goes out and if the worst happens and the redundant goes up in smoke not to worry, each pixel is easily replaceable due to its modular design.

Arduino Tux plant care

Some of us need a little help keeping our green leafy friends happy. The Arduino Tux (translated) plant care system was built to make things a little easier.

The author had a broken tux toy laying around and wanted to do something fun with it. He cut a hole in the front to mount an LED matrix and connected it all to an Arduino. A couple of metal rods serve as a resistivity sensor in the plant’s dirt.

When you water the plant, tux flashes some hearts and a smiley face. As the moisture drops, tux gets less happy with the end result being a big frown.

These are the same people who brought you the Arduino Photolab.

3x3x3 LED cube

[portreathbeach] built this simple 3x3x3 LED matrix. It uses a PIC16F690 in a ZIF socket for the brains. Each layer has nine LEDs with the cathodes tied together. The anodes from each LED are connected to the LED below. The LEDs are multiplexed so that even though all layers appear to be on, they’re being addressed individually. He’s included software, so you can build your own animations. Video of the matrix in motion is after the break.
