We all love to listen to music but some of us want to do more than only listening to music.
We all love to listen to music in every situation it may be a good day or a bad day our favorite music puts a smile on our face. For example, I can use :nth-of-type to hide every nth SVG rectangle or making every odd child have a different stroke-dasharray, etc.Music plays an essential part of life. I can add some additional variation to each theme by messing with pseudo selectors. This lets me override or substitute CSS rules pretty trivially. There are a handful of differently colored themes for each visualization, and I do some rudimentary CSS namespacing by updating a class applied to the html element. Since I'm using D3 - which is just drawing SVG - I was able to style everything in CSS (no images are used at all, including icons). Each visualization uses the data a bit differently - it was mostly trial and error to get some stuff I liked looking at. I'm using d3.js to draw and redraw SVG based on this normalized data. I then normalize the data a bit (or transform it slightly depending on the visualization) and redraw the screen based on the updated array. Then, using requestAnimationFrame (with a little frame limiting for performance reasons) I'm updating that array as the music changes.
There's a good tutorial on how to do this. Using the web audio api, I can get an array of numbers which corresponds to the waveform of the sound an html5 audio element is producing. Party-mode - An experimental music visualizer using d3.js and the web audio api. g810-led -dv 046d -dp c331 -tuk 4 -a 000000 If your keyboard set all key to off you have found the protocol (3), if not, need new dump. g810-led -dv 046d -dp c331 -tuk 3 -a 000000 If your keyboard set all key to off you have found the protocol (2), if not continue. g810-led -dv 046d -dp c331 -tuk 2 -a 000000 If your keyboard set all key to off you have found the protocol (2), if not continue. Now test your keyboard with all supported protocol (for 2019 keyboard start with -tuk 4): g810-led -dv 046d -dp c331 -tuk 1 -a 000000 If your keyboard set all key to off you have found the protocol (1), if not continue. In this sample VendorID is 046d and ProductID is c331. lsusb Sample return : Bus 001 Device 001: ID 046d:c331 Logitech, Inc.
Start by retrieving the VendorID and the ProductID of your keyboard using lsusb.
