Hello to all, Just recently I have released a small utility which I have build for my self just to track the battery charge level based on battery amperage at my menubar. Simply because OSX tells a little lie about the your fully charged battery level. So - http://ec2-54-149-58-132.us-west-2.compute.amazonaws.com/. It cost nothing and it’s very simple and easy to use. In case you can extract the information you need with shell script then you can track it on your OSX menubar. Simple how it works: Video guidelines how to configure this little tool. Out of the box I have build few scripts just to demonstrate what you can achieve with it: Stock market trend indicators from Bloomberg.com Currency exchange rates, stock selling prices, metal and everything else from bloomberg.com on your OSX system statusbar. Keep an eye on your GMail inboxes by tracking unread emails. Single or multiple GMail inboxes can be put under surveillance by tracking unread emails in your inboxes. Don't trust OSX on your battery charge level as it says little lie about it. Real battery charge level can be accurately calculated based on battery current and designed amperage. Keep an eye on current weather conditions on single or multiple locations. Temperature and cloud coverage information for your preconfigured location. Keep an eye on your facebook account unseen notification. Facebook unseen notification counter at your OSX StatusBar Batteries have a limited amount of charge cycles before they are considered to be consumed. Are you aware of remaining number? Keep an eye on this counter and maybe turn-on the ECO mode. If you will find this useful or you will start some interesting scripts for this little tool share with me your experience Enjoy!
