DIY LED COSTUME Gijs Molenaar - KAT-O - Cape Town
- 23 May 2016
HTTP://YOUTU.BE/WMFSZ7VH810
None
WHY?
- me “Why not.”
Play with embedded hardware Prosuming @ AfrikaBurn
THE INGREDIENTS Digital RGB LED strip WS2812B - 60 LED
- 2.5 M ( € 50 ) 8000 mAh powerbank ( € 50 ) Arduino Uno ( € 25 ) Suit, custom made by friend ( € can’t remember ) Money belt ( € 2,50 )
RGB LED STRIP
None
each cell containers 3 LEDS Red, Green Blue 0-255 brightness
per led 16M different colors Cascading port transmission signal by single line Number of LEDS depends on update freq
PRACTICAL LED LEDs are very bright Used 25% brightness
‘SCHEMA’ 3 wire connections Flexible cat-5 for connecting strips
POWERBANK € 50 Off the shelf could run for 2
days still use it often
ARDUINO UNO Real time 14 IO pins 2 KB mem
PRACTICAL ARDUINO very easy to do runs out of memory
quickly (my poor embedded programming)
THE SOFTWARE using FastLED http://fastled.io/ Array based, no worries about
timing
EXAMPLE #include "FastLED.h" CRGB leds[1]; void setup() { FastLED.addLeds<NEOPIXEL, 6>(leds,
1); } void loop() { leds[0] = CRGB::White; FastLED.show(); delay(30); leds[0] = CRGB::Black; FastLED.show(); delay(30); }
MY SOFTWARE https://github.com/gijzelaerr/nye-outfit
None
THE PROBLEMS fragile hardware change requires software
