Inspired by the sustainable and low-cost farming efforts in Kenya (, we consulted with Professor Brian Lilly in order to tackle to issue of sustainable fish farming in Kenya. The intention is to create a low-cost tank monitoring kit to aid in the monitoring and efficiency of running a sustainable small-scale aquaponic farm.

We are looking to sense the pH, ammonia, nitrite, nitrate, or oxygen levels (or some combination of) levels of a small-scale fish farming tank. Currently, this farm has no electronic monitoring equipment. Our goal is to be able to interface together an LED display, solar panel with small battery for power, and the necessary sensors to improve the efficiency of the small-scale farm. Our design would be useful for assisting the farmers in maintaining multiple tanks and improving their profit margins. The ultimate goal of the project would be to create a very low-cost kit for fish farmers.

We are proposing to use a pH sensor (conductivity-sensing), dissolved oxygen sensor, microcontroller, battery pack for when the sun goes down, solar panels, and controls for the pre-existing pump (acts as oxygenator). The battery would power the system for about 4 hours total overnight and we have estimated a 60 WHr battery will be used.

As a potential stretch goal, Professor Lilly is interested in gathering the sensor data and uploading it to a server so he can track the tanks while here in the United States. We may implement this extra feature with Arduino.

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.
