We propose using a pair of gloves to control light design on a stage, which can be used for uses practical to musical performances and theatre shows. The purpose of this project is to accomplish simpler goals in relation to these areas rather than running a full production. This could be controlling a spot light on an actor or, in a musical production it could allow a unique control over the lights that most, if any, groups out there do not have. This means the focus would be more for the flash and performance, or simplicity in the case of theatre, than for large scale utility.

There will be a limitation to keep the complexity within the scope of this course. The limitation is that the light designer cannot walk freely in relation to the lights. The designer must remain behind or in front of the lights. Think of this as the light designer must be on stage directing the lights or off stage. With this limitation, we will not have to solve the problem of keep track of where the designer is. Now with the designer and lights both in fixed locations, we will still have a control unit with all the lights in the system connected to the control unit. All lights in the system will be servo motor based. The designer will still wear a single glove that communicates to the control unit via Bluetooth.

The glove will have its own microcontroller, and bluetooth transmitter, one flex resistor in the pointer finger, and four buttons and four LEDs, and will be powered via 9Volt battery. The designer will select which lights to control via the buttons and the glove will indicate which lights are currently selected via the LEDs. Further, the designer will control which direction the currently selected lights point at by pointing his finger and gesturing the direction he/she wants the lights to point towards. When the finger is not fully extended (flex resistor not active), the lights will not move.

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.
