And Now For Something Blinky

Posted 2011.01.06 9.59 in Computers/Internet/Technology, Hobbies

It’s (pocket-sized) blinkin’ flashin’ heaven.

The LoL Shield (Lots of LEDs) is an add-on board for the Arduino microcontroller prototyping device.

One hundred and twenty-six LEDs, all on a space of about 3″ by 2″, all a-blinkin and a-flashin.

Of course the first thing I wanted to do was run Conway’s Game of Life on there. Turns out there was a GoL program already made, in the associated library / examples. Still, I had to tweak it a bit to get it to work ‘just so’.

Now all I gotta do is replace the Arduino with something smaller, maybe just the Atmega uC, add some batteries and put it in a little portable case.

Real electronics should glow in the dark.

Blinkin’ Flashin’ Bliss

Posted 2010.12.15 0.57 in Computers/Internet/Technology

It’s a problem I’ve confessed to before. I love blinkin’ lights. LEDs, blinkins, flashins, flickering their magic little messages… and just recently, I’ve come across a wild and wonderful blinkin’ flasher that’s just plain blissful blinkin heaven.

Not only does it enchant and calm with it’s blinkins, but it also performs fun mathematical calculations. See, it’s based on Conway’s Game of Life.

It’s a GoL kit – modular boards, each with a 4×4 grid of cells (represented by LEDs). The boards can be linked to build larger and larger grids. I’ve started with 6 boards, for a 12 x 8 grid. It’s very addictive though. I already want to get another 6 boards and go to a 16×12 grid.

Here’s a short animation – it’s not perfect, there’s missing evolutions so the animation doesn’t exactly portray the way the game runs. But it’s close enough: a bunch of (seemingly) random flashes of LED light.
