Introduction to Pattern Recognition: A Matlab Approach

Inspired by the art of Celtic and Scandinavian medieval craftsmen, as translated through intelligent 21st century engineering, Ugears is proud to introduce the Hurdy-Gurdy—the world’s first (as far as we know!) mechanical model for self-assembly that is also a musical instrument. This extraordinary mechanical model kit is truly one of the gems of our catalogue. This isn\'t just a toy, it\'s a full-fledged musical instrument that you build yourself. The Hurdy-Gurdy has a sound that\'s perfect for folk melodies or dancing, bringing medieval times into the present day. When you purchase the Hurdy-Gurdy you will experience a unique combination: the fun and challenge of building, the appreciation of outstanding engineering and design, and the joy of music.

The Pendulum is a stylised educational model, an interactive study guide to the mechanism, only for learning its essentials and principles of working. The pendulum is one of the basic and most reliable time measuring mechanisms. Its working principle is based on the model\'s constant amplitude oscillation under the force of gravity (weight) and potential energy (tension force) of the rubber band. UGears 70133
