TremorBar is a palm-sized assistive prototype for people with shaky hands. It runs a short vibration session using an ATtiny85-controlled motor inside a smooth 3D printed case. The goal is to test whether palm vibration plus ergonomic weighting can temporarily improve hand steadiness before tasks like writing, eating, or using keys. It is not a medical cure but a low-cost experimental tool tested using simple before-and-after tasks.
