  • Screaming Altoids tin just in time for April Fool’s

    altoids_screamer

    Maker [Dino Segovis] has started on a project he calls “Hack a week” where he will be putting together one hack or project per week, for a full year. The first installment of his video series was finished just two days before April Fool’s, and appropriately enough covers the construction of a circuit you can use to prank your friends.

    The “Altoids Screamer” is a simple circuit based on a 555 timer that he built into a standard Altoids Tin. The 555 timer is used to generate a loud pitched squeal whenever the tin is opened. This is accomplished by wiring up the 555 in astable mode, and connecting it to a speaker to output the sound. A micro switch is installed inside the tin to detect when the top has been opened, triggering the “scream”.

    While it’s not the most complex circuit we’ve seen, it definitely gets the job done and is easy enough to build in time for tomorrow’s festivities. It is a great hack for the office, the library, or any other quiet place.
