If one is to video record a table meeting in a medium sized room and the video needs to always capture the person who is speaking. It is hard to do that without a cameraman.
The product will provide a solution to this problem without hiring a cameraman. Camera will be placed on a 360 degree rotational base which can be placed at the center of the table. The base is surrounded by electret microphones. Where the sound is coming from can be detected by analyzing the loudness at each microphone. And a micro-controller will control a motor to rotate the camera to face itself to the speaker.
It will have two cameras working together,, and the two cameras can be rotating to different angles and automatically generate splitscreen if two people are talking (e.g. one asking question & one answering). Otherwise only one camera will be recording.

Featured Project

Our project explored the every-expanding field of drones. We wanted to solve a problem with the dangers of plastic propellers as well as explore new method of propulsion for drones.

Our design uses a centrifugal fan design inspired by Samm Shepard's "This is NOT a Propeller" video where he created a centrifugal fan for a radio controlled plane. We were able to design a fan that has a peak output of 550g per fan that is safe when crashing and when the impeller inside damaged.

The chassis and fans are made of laser-cut polystyrene and is powered using brushless motors typically used for radio-controlled helicopters.

The drone uses an Arduino DUE with a custom shield and a PCB to control the system via Electronic Speed Controllers. The drone also has a feedback loop that will try to level the drone using a MPU6050.

We were able to prove that this method of drone propulsion is possible and is safer than using hard plastic propellers.
