The Slidify is a device meant to easily control music wirelessly from a mac/linux computer. This solves a number of problems. First, you never have to keep spotify (or other music apps) open on your computer again, because all the info can be read right from the Slidify's display. This can be handy to save screen space. Another function is to control music while your monitor is off, for when you want to work focused without distraction from your computer, for example.
- Raspberry Pi 3b+
- 3.5 inch display
- Rotary encoder
- Motorized slider potentiometer
- Motor driver
- Battery pack
- 3D printed housing
- Power adapter
- A lot of wires
The Raspberry Pi is used to run all the code on the Slidify. It takes care of controlling the display, rotary encoder and slider. It also connects to a computer to retrieve information and execute commands.
The display is used to show all necessary music info such as: title, artist, cover image, and possibly length, album and the title and artist of the previous and next song.
The rotary encoder is used to control the dial. Turning the rotary encoder allows you to turn the volume up or down and pressing puts the song on pause/play.
The motorized slider potentiometer was the biggest inspiration for this project. It can be controlled by a motor to automatically move to the position where the song is located. The slider can detect touch and determine position. Moving it to another position will move the song to that location in the song. At the ends of the slider, I want to give the slider a counter force with the motor so that it feels a bit like a button. By moving the slider all the way to the ends it will go back or forward a song.
