Buy "Timer" OTC?
My wife, recovering from serious back surgery, is in therapy and has a list of exercises to perform.
But she doesn't like counting out, one-thousand-one, one-thousand-two....
She asked me if there was a timer where she could push a button and 30 seconds later it would issue a single "beep".
I could easily whip up such a circuit, but I can't make it very small and in an "esthetic" housing.
Does such a device exist for purchase?
Thanks! ...Jim Thompson
A sand timer is cheap but ain't got no beep.

But not convenient to watch while flat on your back with one leg raised and turned out. ...Jim Thompson
A pneumatic delay light switch is settable to 30 seconds and will click when finished.

Buy a stopwatch/count down timer from EBay.. a few $$

Many cooking timers will hold a set time and just require hitting the start button to run another cycle. Look in a store that sells cooking supplies.
Just use a computer or smartphone.
Here's one for the computer.
And another

Since I design chips for smart-phones I wouldn't own one ;-) ...Jim Thompson
Perfect.

iPod Touch? It does all the same stuff as an iPhone, except without the phone. It's essentially a nice ARM-based pocket computer.
Also around $300 cheaper, and also has a timer app built-in with a very loud BEEP and LED flash on expiration, for our older friends ;-)
Does she have a smart phone? There are apps for that -- but that's all I know. My wife uses an exercise timer that does that.
Just takes the right buzzwords... "count down timer" got me one on Amazon (from whence all good things come ;-) that does just that... and holds the setting, so that you can do repetitive sets.
Thanks! ...Jim Thompson

We use them on ESS testing :)
while read -p "press enter" a; do sleep 30 ; echo $'\007' ; done
Or make an audio cd with 30 s silence and a final beep. Trigger is the "Play" button of the cd player. A cheap mp3 player would also do the job.
Does your TV have a sleep timer?
