From the new book Wearable Tech Projects by Sophy Wong – Smart backpack with wireless charging pocket. Never run out of power while out of the house again.
Many mobiles now come with wireless charging capabilities, allowing you to charge your phone by simply placing it over a base – no cords or plugs needed! In this project, we’ll add a wireless charging pocket to a backpack for holding a portable Qi charger. A portable charging bank is also a great source of power for wearable projects, so we’ll add a strip of NeoPixels to act as a visibility light and status bar. The light will glow when the charger is on, so you’ll know when power is flowing!
The project is controlled with an Adafruit Trinket M0 controller and lit using a strip of Adafruit NeoPixel smart LEDs. The project is programmed in several lines of CircuitPython, Python on microcontrollers.
