Alexagate: Ultrasonic Jamming for Amazon Echo 6 years ago
How do you mean bulky? BuzzOff is 14mm thick, sits under your Echo and doesn't require a separate power plug. Rather than blasting ultrasonic noise, BuzzOff shares power with, and controls the power flow to, your Echo.
We could make BuzzOff quite a bit thinner, but the Echo power plugs are the limiting factor, they are almost 10mm diameter.
