This is a Project made with Fritzing, Arduino&Teensyduino. named Venti POV 80HD.
Completed in summer 2018. Thanks for all the help from Fritzing community and PJRC community
Defined to used in Flow arts, poi or staff spinning, and drawing pictures by Persistence Of Vision (POV)
a 3-part board with a Teensy holder, a touch pad cap, and 2 sides of apa102 LED strips(hard PCB style)
Hardware starring: Fritzing designed PCB boards, Teensy 3.6 development board, Apa102 I.A. RGB LEDs.
I’m no professional and very-unnoticed about any rules in schematics,
I use pads and holes like whatever I like, not sure but they did work.
so if you see any unreasonable design in your sight,
please reply so I can understand and fix them
for more details about the project see PJRC forum for reference :
Also the three maded board in the same file :

Please focus in the PCB view, I made no effort in other views.
circle: touch pin extended to reach user easily, and worked nice
USB slot was done by many holes, another slot is for a DC1.3mm plug so I can charge the battery thru.
I use thin wires to separate ground-fill to some shape intended. (this takes long time on ground-filling if your shape was complicated. )
80 apa102 LED strips: 80HD means 80 leds in a High Density of 4LEDs / Cm. Some hard time wiring and soldering. The back of the board is extra pads for extra possible places for battery connections. Carefully connected to ground, but not MOS-drain, so apa102 was not powered without T3.6’s pulling.
The N-mos drain is connected all the way pass the board so every LED gets the same resistance from wiring, and shows same brightness.
holder: with a MOS controller,battery level divider resistors and capacitors for Lithium battery.
I didn’t use all the pins from Teensy 3.6 so not all the pins are placed and soldered. (I’m so lazy)
Also it was better focused with less pins laid.
