We’ve just thrown the switch on a new Arduino library for creating LED matrix displays using NeoPixel LED strips, pixels or shields. All the functions in Adafruit_GFX are then available: lines, filled shapes, text, etc. The photo above shows three separate 10×8 matrices made from NeoPixel strip (240 pixels total — 4 meters of strip), tiled together into a single display…the library takes care of all the permutations! It’s also a great companion for our NeoPixel Shield.
Have you ever done something silly on a lark and then found it was a big hit? So it went with a “beta test” Halloween idea on the Adafruit Show & Tell last week of my electronic demon costume. This video is a summary of what was done there… and what I’m now scrambling to finish properly before the big day! Video on YouTube (please subscribe!) and Vimeo.
Some updates since this was shot: a Ustream chat participant during Show & Tell suggested using a paintball mask as a base. I’m currently working on the faux ribcage idea… there may be enough space to move most of the electronics there and have just batteries in the pack. We shall see!
HAPPY HALLOWEEN! Each day this month (Monday-Friday) we’re going to have a special “Electronic Halloween” post here on Adafruit. It will be a hack, mod, project or something we’ve found that combines all the best things about electronics and Halloween.
I spent Tuesday afternoon strolling the expo floor at the Embedded Systems Conference (now one of several concurrent events under the “DESIGN West” banner). It’s a big industry show for component electronics and test equipment…mostly out of my league, to be honest…but nonetheless interesting to drop in and see what’s new and where things may be headed.
