Do you recall when you were a kid, and there was nothing quite so fascinating as an old-fashioned spring doorstop? You know, the kind that goes “sproi-oi-oi-oing” with any errant tap? A Reddit apartment dweller, having presumably endured one late-night Riverdance rehearsal too many, decided to weaponize this experience.
He attached said sproinger to an activation arm, mounted it to the ceiling, and powered it with an Arduino microcontroller to give it voice activation powers via Google Assistant. Now with the voice command “hey Google, turn on the TallyWhacker,” the arm bar rolls, the tally is thusly whacked, and the upstairs neighbor presumably begins drafting an email to the landlord. To add a bit more fun to the process, the arm bar will oscillate randomly for between five and thirty seconds.
