MightyMonitor
Mighty Monitor is a simple but useful desktop widget that displays the battery status for Apple's bluetooth keyboards and mice. Battery status is displayed as percent remaining. The widget status will change color to warn of low batteries - with a low status warning (yellow/orange) at less than 25% remaining, and alert (red) with less than 10% remaining.
[11/3/2009] Mighty Monitor 2.0 is now available for testing. In addition to supporting the Mighty Mouse and the Apple Pro Wireless Keyboard, MM 2.0 adds support for the Magic Mouse and the Apple "Brushed Aluminum" Wireless Keyboard. It is setup for the Mighty Mouse and the Apple Pro by default. Flip the widget over by clicking on the "i" in the bottom right corner to set the widget up for the Magic Mouse and/or the Brushed keyboard. MM 2.0 drops support for the original Apple Wireless Mouse. If you use that mouse and version 1.2 or 1.3 does not work, then you are out of luck. See the download link at the bottom of the page. Please drop me a line and let me know if it works (email link at bottom of page by clicking on my name).
[11/2/2009] Mighty Monitor is currently undergoing some updates to hopefully make it work well with Snow Leopard as well as the new Magic Mouse. I do not have a Magic Mouse, and I am still currently on Leopard, so I am relying on some help from a few MM fans to try and get it updated. I hope to have an update soon. The newest version will drop support for the Apple Wireless Mouse so if you are using that mouse with snow leopard and the current widget doesn't work, then you are out of luck. The Mighty Mouse, and (hopefully) the Magic Mouse will be supported for Leopard and Snow Leopard. If you are currently having NO problems with Mighty Monitor, then I do not recommend you upgrade.
Mighty Monitor runs the following from the command line to get the battery status:
For the keyboard:
% ioreg -n "IOAppleBluetoothHIDDriver" | grep -i "batterypercent" | sed 's/[^[:digit:]]//g'
For the Mouse:
% ioreg -n "AppleBluetoothHIDMouse" | grep -i "batterypercent" | sed 's/[^[:digit:]]//g'
To download the widget, click on the link at the bottom of the page. Version 1.2 adds support for the old-style Apple Wireless Mouse (non-mighty).
My email address is at the bottom of the page, and on the back side of the widget. Feel free to drop me a line. As you can see by how pretty this web page is, I just threw this up there so others could benefit from the widget. Ugly web page, I know, but hopefully the widget won't be ugly :D
