App Controlled Mesh Network Design and Locker System Demo
Fri Aug 6 09:26:44 2021
ZuiDesigns sponsored a Grand Valley State University senior project for 2021. The goal of the project was to create a mesh
network of small devices that could connect to and be controlled from a phone application. This design is now complete and being
presented at GVSU's annual design show.
As a proof of concept for the mesh network being a functional system, the senior project team chose to install the mesh network
in a system of lockers. Users can now check out indivial lockers to use, lock and unlock them as needed, and then return the locker
to an unused state.
The current status of the mesh system can be seen here.
The student created introduction to the project can be seen on YouTube.
COVID-19 Monitoring Website (Michigan)
Sat Apr 3 20:27:44 2021
ZuiDesigns created a COVID-19 monitoring website using New York Times data. This site tracks Kent and Ottawa counties in Michigan to provide a more detailed look at those counties. The graph will automatically add any new data without needing to refresh the webpage. It may be helpful for tracking COVID-19 locally and can be used for COVID-19 displays since the data will automatically update each day.

MSP432 Launchpad Switching Power Supply Shield
Tue Jul 28 22:06:59 2020
ZuiDesigns rarely gets to share PCB design images due to customer confidentiality, but this PCB was completed internally as a quick proof of concept of using the MSP432 as a PID controller to control a switch mode power supply. The design was completed in Altium with all component libraries in our own MySQL SVN Altium libraries (you can see an example of the resistors at altium.zuidesigns.com. The system allows us to quickly determine the best price and in stock options of our ZuiDesigns part numbers at our suppliers and immediately order. It allows prototypes to be purchased and managed without loading down a purchasing department.
Here are the front and back sides of the PCB. The switching power supply portion is at the bottom of the front side.
