Here is one of my more complex projects.
Its a so called RGB Flowerstick / Devilstick wich uses a Teensy 3.2 and very small WS2812B MINI 3535( on a 144 LED / meter) strip
it can load simple bitmaps from a microSD card to project them by rotating. Similar to a POV Display (Persistence of Vision).
To avoid a gymbal lock I did the maths with quaternions… ( took damn long to understand… weeks of confusion and pure desperation!!! )
The rotation is measured by a gyroscope (MPU 6050 Module)
To supply some power, I took two LiPOs wich are used in quadrocopters and a simple step up converter.
I added a few simple animations wich are not influenced by rotating speed.
