BUILD THE ANNOY-O-MATIC

摘要

For years, engineers and technicians have built annoying little circuits that are easily hidden, that beep, or chirp. The AOM (Annoy-O-Matic) brings this practical joke to a whole new level. By using the PIC12F629, this project not only beeps, but the beep cycle appears to be completely random - maybe once every three to eight minutes. Despite its sophisticated operation, it's very easy for any beginning electronics student to build. Even experienced builders will find this to be a fun little project.
