It seems to work on the N8x0, inasmuch as it goes "sheOOIINNGgggg", counts down time, and repeats, bumping numbers up all the way. (I guess that's what it's supposed to do?)
Thanks. Funny, I have been searching for a while for a good flash timer . This will work and does what a blind timer is supposed to do. It would be cool to see a native one, but this will suffice.
