Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

A cantilever ultrasonic motor with nanometer resolution is designed, fabricated, and tested in this article. Two orthogonal first bending vibration modes are used to form elliptical movements on ...

In this paper, we build a micro-ultrasonic motor in the 2–3 mm scale, combine it with a tunneling magneto resistance (TMR) sensor with dimensions of 1.4 mm ×1 mm, and construct a closed-loop system ...
