Our project goal is to create a motorized longboard that can be controlled using a RC controller-like joystick that will tell the longboard to go forward or go backwards. The controller will be designed to be used in one hand. It will use an Arduino and controllers to control the motors. The board will incorporate regenerative braking that reverts kinetic energy back into usable power for the lithium battery, a DC brushless motor capable of turning both ways, and a pressure sensitive kill switch that turns off the motor when a rider is not detected. Another unique aspect of our board is that it will use sensors or an active drive that will aid in turning by turning down the PWM or by speeding up the outer wheel and slowing down the inner wheel once a turn is identified.

Laser Harp MIDI Controller with Musical Articulations

Featured Project

Electronic music concerts usually need eye-catching visual aids to create a certain atmosphere. Laser musical instruments is a great way to do this. We have been thinking of this project for a while and it was ECE445 that made this laser harp come true. The novelty of this project is that the harp-like laser device mainly focuses on playing articulations with laser and sensors, as a true universal MIDI controller, to control timbres that are synthesized or sampled. Articulations include piano/forte, vibrato, tremolo, and portamento. With the help of Professors and TAs, we learned how to pick right the components, design PCB, soldering, and program microcontroller. Those skills are not only useful in this class but also really important to electrical engineers. Also, we learned how to use individual strengths, combined with effective teamwork, in the pursuit of meaningful goals.
