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.

Growing Degree Day Monitor

Featured Project

The purpose is to create an inexpensive growing degree day monitor that records temperature and computes growing degree days for a specific farming field during a growing season. This monitor will be placed near a farm field where it will monitor temperature conditions during the growing season. It will record both the ambient air and soil temperatures over the course of day. These temperatures will then be used to calculate the growing degree days. The cumulative number of degree days will then be displayed on either a seven-segment display or this can be downloaded to a computer. This monitor will be powered through a combination of both solar and battery power.
