Pseudonymous maker “Aquaman,” of the YouTube duo Engineering Dads, has constructed an Arduino-powered machine designed to discourage pickpockets from lifting your pockets — with a hearty digitized scream.
“I do not learn about you, however for the previous few months my social media web page has been flooded with a girl going round Venice screaming [warnings about pickpockets,” Aquaman explains of the project’s inspiration.
“She’s doing God’s work making sure people like you don’t get your crap stolen, and I couldn’t wait to come home when I was over there and work on my first project, which was taking her home with me — or at least her voice.”
Aquaman’s gadget, designed for deployment in a pocket, is simple enough: a speaker and amplifier are connected to an Arduino-compatible microcontroller with a light-dependent resistor (LDR). When lifted from a pocket by anyone unaware of the LDR, it triggers playback — screaming at the top of its electronic lungs that it’s being stolen.
“It’s completely powered by a rechargeable lithium[-ion] battery circuit,” Aquaman notes of the 3D-printed safety device, “so you possibly can take it with you on the go. Sadly, pickpocketing is definitely a really huge subject in Europe, and it is very arduous to stop. This girl has een doing an excellent job of catching it out, so a part of our resolution entails spreading her legacy internationally.
