SparkFun will be closed May 25, 2015 for Memorial Day. Orders placed after 2pm on Friday the 22nd will ship out on Tuesday. Thanks!
Many of us at SparkFun are not only interested in embedded electronics, but also have a love for RC airplanes. So this project from SparkFun customer Tom Hastie strikes especially close to home. Check out the Night Flyer!
Besides having a sweet name (Night Flyer!), this project is very cool from an electronics standpoint. Essentially, Tom is using an Arduino Pro Mini to control four daisy-chained MAX6966 LED driver chips over SPI. The MAX6966s each have 10 channels of PWM control, so with 4 chips, he has a total of 40 channels (or 13 different RGB channels). He uses our SSOP 16-pin breakout so he can use a protoboard to wire up all his parts. What I'm trying to say is that Tom has control over a lot of different cool colors. The result is a pretty awesome airshow!
Tom does a great job of documenting his build so you check out his build log plus a whole bunch of videos like his breadboard with only 1 RGB channel, his prototype circuit with 10 RGB channels, and his completed aircraft flight demo (my personal favorite). Great work, Tom!
