This hulking monument to illumination is [DJJules’s] 6-foot-long ultimate Larson Scanner. If you’re scratching your head in confusion, the Larson Scanner is the ever-popular scrolling LEDs seen on KITT (the car) from Knight Rider as well as on Cylons in Battlestar Galactica (1978), named after the creator of the series.
[DJJules’s] iteration consists of sixteen 10W LEDs, each mounted on a warm sink which bolt on to a 6′ long piece of angle aluminum sourced from a regional hardware store. He utilized a fundamental MOSFET constant present driver for every LED, attaching the MOSFETS to the warm sink with 4-40 screws. Each LED module then links to a TLC5940 LED driver breakout board from Sparkfun, which plugs into an Arduino pro Mini.
Check out the Instructables page for the source code as well as other important details, including safely powering the develop (the LEDs can draw around 1A each), then grab your sun glasses as well as stick around for a quick video below.
