def change_duration():

    global duration

    answer = query(u'How long?', 'time', 18000.0)

    if answer:

        duration = int(answer/60)

        if duration <= 200:

            if query(u'Change to hr:min ?', 'query'):

                duration *= 60



im = Image.new((60,48))

def showtime(rect=None):

    im.clear()

    im.text((5,28), u"%02d:%02d" % divmod(duration,60), font='title')

    c.blit(im, target=(0,0,180,144), scale=1)    # triple size



duration = 300

running = 0

app.body = c = Canvas(showtime)

alert = Sound.open(u'Z:\\Nokia\\Sounds\\Digital\\Cuckoo.awb')

showtime()



def start():

    global duration, running

    running = 1

    while running:

        duration -= 1

        showtime()

        if duration <= 0:

            alert.play(-2)  # repeat play

            break

        if duration % 10 == 0:

            miso.reset_inactivity_time()

        e32.ao_sleep(1)



def toggle():

    global running

    if alert.state() == EPlaying:

        alert.stop()

        return

    running = 1 - running

    if running:

        start()



def quit():

    global running

    running = 0

    if alert.state() == EPlaying:

        alert.stop()

    lock.signal()



lock = e32.Ao_lock()

c.bind(EKeySelect, toggle)  # start, pause, resume

app.menu = [(u'Duration', change_duration),(u'Close', quit)]

app.exit_key_handler = quit

lock.wait()

Remind yourself of how fast time fly with this app.
You should change the sound file to the one you like.
(I use cuckoo.awb)
The duration input abues the time input by treating input
as minutes and seconds instead of hours and minutes.
But if the duration is too short, it will ask you if you mean
hours and minutes.

Make a phone vibrating periodically

korakot (Korakot Chaovavanich) — Mon, 27 Jun 2005 12:54:36 GMT

Some of my friends who practise mindfulness meditation
use an alarm device that vibrate every 2 minutes and
he will become mindful then.
Danny O'Brien of Life Hacks fame asked me about this too.
So, here's a short example (without parameter setting GUI)
that does exactly this.

You need to have miso library install. Only Series 60
2nd Ed FP2 device (Nokia 6630, Nokia 6680) can be used.
See vibrate(...) in miso documentation
http://pdis.hiit.fi/pdis/download/miso/miso-1.40-api.html



import appuifw, miso, e32



# run-and-break type of app

running = 1

def set_exit():

    global running

    running = 0

appuifw.app.exit_key_handler= set_exit



# main loop

while running:

    miso.vibrate(500, 100)  # vibrate for 500 millisec, at full speed

    e32.ao_sleep(10)   # vibrate every 10 seconds

I don't have a FP2 phone to test this. Though the code is
pretty straight forward, please report if there is a problem.
