Project Desciption:
The coil gun constructed by groups in the previous semesters, Prof Reinhard and Chris Barth were able to design and implement the SCRs and related power circuits. Control systems for synchronizing of firing of the SCRs to accelerate the projectile through the barrel still needs to be implemented. There is also a need to design a user interface to operate the gun effectively.

Overview of proposed solution:
VCSELs (semiconductor lasers) couple with photodiodes have been installed on the barrel of the gun to accurately measure the velocity of the moving projectile. The data from these sensors will be used as inputs to a microcontroller/FPGA. An algorithm on the microcontroller/FPGA would give a trigger output to initialize energization of the magnetic coils on the barrel. We could also use a time-of-flight sensor to get an added set of data on the position of the projectile.
The UI would be implemented using a separate controller and an attached screen. It will show details of the shot such as power consumed, barrel velocity of projectile, etc.

Drum Tutor Lite

Featured Project

Team: Yuanheng Yan, Zhen Qin, Xun Yu

Vision: Rhythm games such as guitar hero are much easier than playing the actual drums. We want to make a drum tutor that makes playing drums as easy as guitar hero. The player is not required to read a sheet music.

Description: We will build a drum add-on that will tutor people how to play the drums. We will make a panel for visual queue of the drum and beats in a form similar to guitar hero game. The panel can be a N*10 (N varying with the drum kit) led bar array. Each horizontal bar will be a beat and each horizontal line above the bottom line will represent the upcoming beats.

There will be sensors on each drum that will fire when the drum heads is hit. The drums will be affixed with ring of light that provides the timing and accuracy of the player according to the sensors.

Of course with a flip of a switch, the drum could be a simple light up drum: when the player hits the drum, that particular drum will light up giving cool effects.

The system will be on a microprocessor. Or for more versatile uses, it could be connected to the computer. And a app will be written for the tutor.
