you could tie it into a dollar store stove timer circuit.<div><br></div><div>solder a small transistor in place of the switch (or in parallel to the switch), and have the base leg left open to tie to the output for the buzzer/piezo on the timer. then set the timer to go off in 5 minutes or whatever and hide the whole device... makes it a bit more bulky but it's a dirt simple solution. (and those stove timers are fairly small already, strip the chassis off one and it should be no larger than the annoy-o-tron itself.)</div>
<div><br></div><div>the downside to this method is you will want to tie the grounds together on the 2 devices, or run them from a common power supply, so your battery life will suffer a bit because it's powering both the timer and the annoy-o-tron)</div>
