Homemade Annoy-a-thing (Annoy-a-tron)

Step 4 Final thoughts

after you get all of your components onto your board, the bottom work begins. i try and lay the circuit out so many of the connections can be made by jumping between two adjacent holes with solder. i find the most difficult set to be the underneath work, as it requires steady hands and more thought.

hopefully all has gone well and your annoy-a-thing works! this set up i've just layed out should last about a month.

as with all little projects like this, a magnet can be added to the bottom. this will, however, add thickness, so i prefer using double sided sticky tape.

one of the things think-geek's annoy-a-tron has that this one lacks is a different length of time between beeps. this particular "annoy-a-thing" will beep about once a minute (+/- a few seconds depending on battery life).

ALSO: note that you can change the time between beeps by changing the value of the 10M ohm resistor. if i'm not mistaken, i believe a value of 20M ohm will make it 2 minutes, 30M ohm is 3, so on. (you wouldn't want to go too crazy and make it 10 minutes or something, i don't think that would work. but hey, nothing stopping you from trying!)

your comments are appreciated!

It would be cool to hear it in action or even better to show some unsuspecting person reacting to it :)

Try you tube you will find there, i have seen it working, people going crazy, lol.

Also, instead of changing that resistor you could always add a poteniometer in there. That way you dont have to always change the resistors. You can then have a wide range of times you can input.
