We would like to make a cheap, open source weather radiosonde. Currently, radiosondes are launched in 92 different locations 365 days a year and cost upwards of $250. When they drop back to the surface, the radiosonde is rarely ever recovered and reused.

We would like to develop a prototype that offers a locating functionality. The radiosonde will consist of temperature sensors, barometer, humidity sensor, transmitter and receiver with a quarter wave antenna. In addition to transmitting pressure, temperature and humidity readings, the prototype will offer an option to add an additional sensor to measure research data such as carbon dioxide levels in the air to determine air quality and track variations.

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.
