Hi I just finished, Pomodoro Music Timer, http://codepen.io/MarkoStefanovic/full/ZBJKzV/ it plays internet radio you can choose from 6 stations. Still got to clean the code finished like 10 minutes ago.
if you like to test it in shorter time in JS enter
var workTime = 25; // change to 2 var breakTime = 5; // change to 1
There were many challenges to make the code for this project, first JS timeout isn`t really precise time function but with Date it can run good together. And playing alarm on mobile browsers, because it will not play if user did not clicked to play, but there is workaround
Tested on windows browsers(Firefox, Chrome, Opera) and android mobile(Firefox, Chrome, Opera) and works great, windows IE- not working, android default browser not working great. It took 6 days to build this project. Any feedback appriciated this was monster project.
