NeoPixel LEDs are the bee's knees, but in a few scenarios they come up short…connecting odd microcontrollers that can’t match their strict timing, or fast-moving persistence-of-vision displays. Adafruit DotStar strips deliver high speed PWM and an easy-to-drive two-wire interface, bridging the gaps in the spectrum of awesome.
A PIC is used as a SPI Master to create a simple interface to up to 21845 NeoPixels. After being configured with the number of attached NeoPixels the Pixif continuously retrieves the RGB values via SPI and generates the NeoPixel GRB bitstream. The update rate may be throttled via a synchronization input. This approach frees the host processor to concentrate on its algorithms especially when its SPI Slave has DMA support.
Resistance is futile! The Borg are among Star Trek's most iconic and terrifying villains. Whether its for Halloween or your next Sci-Fi con, this guide will show how can easily put together a great looking Borg costume. By assimilating and adapting some other projects on the site it can really stand out.
If you're like me, you loved the Adafruit Daft Punk helmet that showed up on our blog a few weeks ago... but, as my 3D printer is a little bit smaller than a TAZ, and funds and time are limited, I thought for Halloween I would make my own version, based around a $5 mask from Party City that looks a little bit like Cobra Commander.
