Large remote-controlled Game of Life display

Sometimes it’s just plain fun to over-engineer. [Stephanie] gets a warm fuzzy feeling when she successfully adds way more electronics components to a project than she really needs – just because she can. We can’t really argue with her if that is the intended goal, nor can we find fault with the sweet Game of Life display she put together.

She started off with six Game of Life kits from Adafruit, but she quickly caught the LED bug and her collection grew until she had 20 kits (that’s 320 LEDs for those of you keeping count). After piecing them all together, they were mounted in a wooden frame and placed behind a dark piece of acrylic. It looked great and worked just fine, but it wasn’t overdone enough for her tastes.

In the end, she added a small Arduino and Xbee module to the Game of Life display, which enables it to be controlled by her network-enabled thermostat we featured a few weeks back. The thermostat was fitted with an Xbee unit as well, which allows it to turn the Game of Life on and off at whatever times [Stephanie] specifies.

We’ll take two please.

Music synthesized from the Game of Life

[vtol] has built a very elaborate system of electronic sound machines, which can be patched together in various ways in order to create all sorts of sounds and sound effects. The modules range from simple noise synthesizers to pitch shifters, sequencers, and effects processors. The most recent addition to his synthesizer system is a matrix sequencer named 2112, which focuses on generating random sounds from a very familiar mechanism.

The sequencer simulates Conway’s Game of Life, representing the colony movements in beeps and buzzes, creating a nearly infinite array of random sound effects. Using firmware from the Game of Life board by Ladyada, the sequencer generates different sound patterns based upon the number of colonies on the board. The output varies according to the shapes and proximity of the organisms to one another. Since it is part of his already modular system, the 2112 board can be combined with any number of his other sound generators and effects machines to make all sorts of circuit bent music.

Needs more LEDs, EMSL biggified Conway’s Game of Life

Evil Mad Scientist Laboratories has proven bigger is better with their colossal LED table running Conway’s Game of Life. At the heart of the system is 44 ATmega164Ps controlling 352 LEDs on a 32×44 inch table; and to make it interactive IR LEDs detect the presence of objects.

The display is set up as an exhibit at the San Jose Museum of Art in tribute to [Leo Villareal]. To see a demo, catch a video after the divide.

LED Life and Charlieplexing

Yesterday, we featured [Andrew]‘s orientation aware camera. We want to highlight another one of his projects: LED Life. It’s a 6×5 LED matrix playing Conway’s Game of Life. He used the low power MSP430 like our e-paper clock. The best part of the writeup is his explanation of how Charlieplexing works. Microcontroller GPIO pins generally have three possible states: output high, output low, and input. This combined with the directional nature LEDs and some creative wiring means you can run a large matrix of individually addressable LEDs with just a few IO pins. Instead of just flipping the IO pins on and off you change their assigned state. Have a look at [Andrew]‘s site for some great illustrations of how the system works. A video of his LED Life board is embedded below. Read the rest of this entry »
