Inspired by the Wuvuzela app (and possibly by the announcement of Portal 2 at E3), I've developed a simple little application that allows you to blow into your phone's microphone to blow out candles on a cake.
The options screen, displayed before running the app, now allows you to Calibrate your device's microphone. Simply touch "Calibrate", press OK, and blow into your phones mic until told to stop. The minimum decibels needed blow out the candles are now set to your current environment.
You can also enable the tune, which will play the Happy birthday tune after blowing out the candles.
Finally, you can change the preset message to something more personal, such as "Happy Birthday, Michele!"
-Blow out candles with your phones mic
-Custom birthday message
-Calibrated to your environment
-New, prettier birthday cake
-Happy birthday tune played in the background
Tested and working on my HTC HD2, but should work on other devices as well.
Let me know what you think/if you have any problems.
