G+_Mark Olson Posted May 29, 2018 Share Posted May 29, 2018 General Discussion My two identical twin girls are graduating from High School this year and we have been working on an enhancement for their Graduation Caps using WS2812B LEDs and the FastLED library and Arduino Nanos. The code (so far; still working on jazzing up the patterns), semi-schematic, 3D files and etc. are here: https://github.com/Mark-MDO47/GraduationCap2017 I am using four 93-LED Mokungit WS2812B 5050 LED "disks" per cap and four Arduino Nanos per cap. The Readme.md file in https://github.com/Mark-MDO47/GraduationCap2017/tree/master/FirstCap has an index of pictures and videos. Two videos I am particularly proud of are btn 1 - - Down the Drain and Hauntedbtn 2 - - Radar with POLY and 2018 As time is approaching I broke down and used some of the FastLED demos: Demo Reel 100 and Fire2012, both by Mark Kriegsman. He can do in 20 lines of code what takes me 500 lines! The power was an unexpected issue for me. I wound up using three parallel sets of three 18650 batteries (11.1 volts x 3) for the LEDs, going through a 10-amp peak UBEC. I used two rechargable 9-volt batteries in parallel (9 volts x 2) through a standard UBEC to power the Arduino Nanos. The batteries hide in the girls' purses. I recently got a text from my wife and found that she has assigned me the name "Blinkey Lights" on her phone. Enjoy! Mark Link to comment Share on other sites More sharing options...
