I build a little gadget to prank my lovely wife. WARNING! THIS DRIVES PEOPLE NUTS! DONT DO IT TO SOMEONE WHO IS LIKELY TO PUNCH YOU IN THE FACE.\r<br>Makes annoying beeps at random intervals. The random pitch and interval makes it very difficult to pin-point the source of the beeping. I might clean up the design and spin up a few circuit boards if anybody is interested in an easy build-along vid.\r<br>Thanks for your help! \r<br>\r<br>Heres the code:\r<br>/*\r<br> Lil BASTARD ZEN BLASTER\r<br>WARNING!
