Let’s give this project a round of applause!
Guess who’s back with another robotic solution to yet another problem. Simone Giertz, of course! Any of us who’ve ever had to sit through a graduation ceremony, an hour-long presentation, a tennis match, a ballet recital or a political debate know all too well how annoying having to constantly give an applause can be.
So, as part of her aptly named “There Must Be A Better Way” series, the frequent YouTuber and Maker has developed an automated applause machine. Why? Because “clapping your own hands is tiresome and a cruel practice.”
For the mechanism itself, Giertz employed a pair of kitchen tongs and attached a metal spring below the grippers, then put an oval-shaped DC motor between the two arms. This way, when the motor spins, it forces the tongs to open and close, creating a clapping motion.
“For the machine’s hands, I wanted to find a pair that would create the most realistic clapping sound possible. So I bought four different types of plastic hands from a party-supply store. After some experimentation, I decided that hollow hands made of rigid plastic created the best noise. I fastened them to the tongs’ grippers with small bolts,” the Maker explains.
The machine was brought to life using no other than an Arduino Uno (ATmega328) connected to a MOSFET, housed inside a laser-cut base. What’s more, a slider was added to the front of the device to control the speed. According to Giertz, she can now gradually adjust the applause from a “snarky slow clap” to a “breakneck 330 claps per minute.”
Admittedly, this may be one of her best, most practical and well-polished projects yet. We love it! Now how ‘bout a round of applause for Giertz?! You can watch the future of clapping hands below, as well as read her recent write-up in Popular Science here.
