RGB Flowersick with Teensy 3.2 and WS2812B mini and gyroscope

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.

I'd be interested in your code as well. I'm tinkering on a POV light stick with gyro control with an MPU6050 as well, even if it's a mess, seeing your draft code in a gist or something would be a huge help, even if your specific parameters only work for your project.

What are you using as the tips? The look really cool and seem to be able to absorb some impact when dropping it. Btw.: I would also be interested in the code (even if its a mess :D)

really nice project :D is it on github ?
