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 ![:slight_smile: :slight_smile:]()
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 ![:slight_smile: :slight_smile:]()

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 ![:slight_smile: :slight_smile:]()
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.
