With a pair of Photons and a MP3 shield, I can have the Imperial March start playing in the house when I arrive home.

A captivating visualization to help my daughter understand the passage of time.
Persistence of vision is an optical illusion, it works on a simple phenomenon how our day to day television works.

The simplest modification would be just to hard code the timer's duration - I would start there. In order to do that, comment out all the code in the loop function except this line:
Now, instead of getting the duration from the phone, it will automatically set the duration for one minute and start the timer.
If that doesn't work, you may have to also comment out the initializations of the virtual shield (line 12), the screen (line 15), the speech (line 18), and the recognition (line 21) as their maybe errors thrown if there is no device available (I can't remember).
Definitely. You can either hard code the duration of the timer or use so other input mechanism. For example, I have a version that has two buttons - one button adds a minute to the timer's duration each time it's pushed and the other button starts the timer.
Yes. You'll just need some other way to set the timer. I have done a variation which uses two momentary push buttons. When one button is pressed, you are adding a minute to the timer (and one LED is lit for each minute). Then, when you press the other button, the timer starts counting down. That way everything self contained and you don't need a bluetooth modem either.
