A Giant Mechanical Finger Built to Deliver Powerful Flicks
【Tech Seeker 2026】最強のデコピンと尻尾 | ProtoPedia
A team including sousci is developing an oversized mechanical finger designed to deliver powerful finger flicks. The project uses a large mechanism to amplify a simple flick.
The work-in-progress device is documented on ProtoPedia and uses components including Arduino hardware and servo motors.

To make a finger flick more powerful, they built an enormous mechanical finger. That's a lot of hardware for a single flick.
