Hello everyone! I’m back after a massive break where I almost forgot about this app. This I discovered when I was messing around with my Snap Circuits set, and the basic idea is that if you wire up a relay like the one shown here, it will switch states so fast that it emits an audible buzzing noise! Obviously it doesn’t here, since EC has no sound, but it does in real life. Go ahead and build this in real life if you want to, but you don’t need 100V to power it. Just get a low-voltage relay and wire it up like this, with only about 6 volts powering it. That’s literally all you need, just 6 volts makes it oscillate like it does here with 100. Have fun!
