I have a question for Tasker users (or anyone who has another idea of how to do what I want).

My old non-smart phone would pop up a message on the screen and play a little tone when the charging status changed.
"Charging" doo-beep!
"Charger off" bee-doop!

I've looked high and low for an app that would replicate this action on my 'smart' Droid.
Unfortunately, I have been unsuccessful in my search. The problem is that the typical Droid indicators of charge status are only a few pixels in size, or in my favorite battery app, Battery Monitor Widget Pro, the (very small) text changes from red to green.

I need to be able to toggle a tone and/or message based on battery charging status.
Any ideas?
