Are you working in an office where kitchen timer noise disturbs your fellow neighbor? You want a signal after 25 minutes, but it must not be audio-based. The question was raised at the Pomodoro Technique mailing list. David White had the answer. At Think Geek, you can buy a “Sonic Bomb Alarm Clock with Bed Shaker” for $ 39.99.
The original purpose of the Sonic Boom Clock is to wake up the deep sleeping Ninja. But it can of course also be used to signal to the deeply focused Pomodoro Technique practitioner that it is time for a short break.
The recommended way to use it, according to Think Geek is: “Turn the sound alarm off and tape the bed shaker to your office chair. You’ll be vibrated awake without disturbing the drones.” But it can certainly also be used as a standalone Pomodoro on your desk.

Any ideas for a silent ticker? I feel that the ticking (with a low level of sound) helps me focus. It signals that I’m in a Pomodoro. So my Chimoo Timer for my Mac is set to tick. Can the Sonic Bomb also tick silently?
It appears as the Sonic Bomb is quiet until T time.
If I wanted tick sound for 25 minutes but no ring, then I’d tweak a mechanical kitchen timer. Open it with a screw driver. With a pair of pliers, cut the hammer that hits the bell. Close it again.
Tick sounds are still there but the ringing is gone.
