"FilxCapacitor" - Music Box / Lights Show / Photo Slide Show / Clock
This box was created as a present for a dear friend at the time of need, and the idea was to create a bed-side clock that can additionally function as a mesmerizing media box, with some uplifting music and photos collected from friends.
Project source code: https://github.com/kigster/FilxCapacitor
Inside, it is powered by Teensy 3.1 with an Audio Shield, two 3W speakers and a small digital amplifier, 4 Adafruit NeoPixels, a Joystick to control photo show and tracks, as well as the rotary encoder on the top to control music volume, or to help set the time in the Time Set mode.
Audio shield was supplied with a 16GB high throughput SD card, which contained both pictures (in BMP format) and audio files (as WAV), and Teensy was able to playback the files while
at the same time reading another file for display! Pretty awesome. 320x240 TFT display did a great job at keeping color accurate and very bright. Although to control backlit display brightness I chose to use an adjustment potentiometer, so that I could tweak it after the assembly.
As the box's main and unexciting mode is to be a bedside clock, amber LED display (also from Adafruit) was used to show the current time. For Teensy to be able to sync the time, a crystal was soldered onto the bottom, and a 3.3V backup battery supplied.
Overall this is probably the most complex project I've ever done with Arduino compatible hardware, and the codebase, when converted to hex used up about 30% of Teensy's enormous memory buffer.
Anyway, this is my first project video, and hope you enjoyed watching it! Please leave comments if so :) #arduino #teensy #audio #diy
