Maintaining a complete list of alarms on both the PLC and HMI can be tedious and inaccurate to such an extent that when it’s time to crunch, alarms get missed that really should be created in code and added to the HMI. This difficulty can cause “ghost” faults in the Read more…
Developed an in-browser web application that takes DWG and DXF files and converts them into files that can be imported into Allen Bradley RSLogix 5000 / Studio 5000. The generated aliases point to hardware points in the correct format for their respective modules. The resulting code will then have information Read more…
Created a web HMI using no proprietary software that communicates with an Allen Bradley PLC system and an Oracle database to display complex part gauging and data and relay part data between the plant database and the PLC. The HMI application was written in React JS, communicated with a Node.JS Read more…
A web application that analyzes images for standard color harmonies, searches for a best fit, and then filters the input image to fit the harmony better. The harmony may be changed, and hue can be selected manually. The idea is to allow artists, photographers, and videographers to analyze their own Read more…
I worked with another graduate student in mechanical engineering at NIU on a project to replace the controller of an old CRS robot. Each joint was controlled by an arduino, and the arduino’s were coordinated by a computer. The computer ran a python program which went joint position commands to Read more…
This is a system that can be used to design crank-rocker style linkages that follow a desired path. First the user designs a path by moving some points. Then an initial linkage design is set up. Once the optimization is started, a genetic algorithm performs a very intelligent, evolution-based version Read more…
Inverted pendulums are a classic example used when teaching about PID controls. I built a physics simulation and PID controller in the browser. It uses RK4 integration for the physics for precision and efficiency. This simulation can be used to do hands-on teaching about PID controllers. Click here for the Read more…
This is an in-browser real-time simulation of 2D quadrocopter physics and controls. It has many changable paramters. For the purposes of demonstration, this quadrocopter is tasked with sorting blocks based on colors. An artificial neural network is used to learn the pattern of what colors go where based on what Read more…
SpreadUbuntu is a website that acts as a respository for editable marketing materials. The project was successful enough that I became an Ubuntu member with an @ubuntu.com email address and voting privileges. http://spreadubuntu.org
This is a web application that I made in my free time that helps a company to track open tasks, project documents and data, and assignments for projects, which can then be shared with the customer. It uses Semantic UI and Drupal 8.
