I've built on the PuckJS media controller, to add some functionality. I've published it to a github repo and thought I'd share my progress. It will do different things, based on the click duration and orientation of the device.
disconnect: click and hold, > 2 seconds
connect to last device: click < 2 seconds when disconnected
connect to PC's bluetooth ID (for updating firmware, etc): click > 2 seconds when disconnected
play/pause: short click
next track: longer click, right-side-up
prev track: longer click, upside-down
volume up: click and hold while rotating from upside-down to right-side-up
volume down: click and hold while rotating from upside-down to right-side-up
My original intention was to use the puck's axial rotation (think rolling the puck along a surface while pinching between finger and thumb), but couldn't determine whether the device was moving clockwise or counter-clockwise. This means that you'll need to use radial half-rotations to control volume one increment/decrement at a time.
This is mostly a test of how to incorporate the puck's sensors into a usable UI in its most minimal form. Hope others find something useful here!
Nice - thanks for posting it up!
It's very cool that you managed to use the magnetometer to detect flipping the Puck over.
I've got one here that I screwed to a piece of wood (with a screw right in the middle of the case), and then I hid a magnet in the wood. You can then use the magnetometer with Math.atan2 to actually get a rotation value as you turn it - not sure if that'd be useful here?
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
