Using an A4988 stepper motor driver

**Edit 11/2/2020 : changed the reasoning for multiplying by the constant 8 **Edit 11/3/2020 : used 1A instead of 2A for safety purposes Yesterday, I spent some time working on my senior design project (don’t worry, I still made time to have fun during Halloween hehehe). I decided to focus on the NEMA 17 stepper… Continue reading Using an A4988 stepper motor driver

Demo of the machine vision camera and 3D printed parts

Today was my team’s first meeting with Johnson Matthey and Keyence. So the camera that our team plans on using is from Keyence and it’s called “Inline 3D Appearance and Dimension Camera unit 24‑mm 0.94 type .” I wish I could’ve taken a video of the demonstration. I thought it was pretty cool that this… Continue reading Demo of the machine vision camera and 3D printed parts

Crystal Craft

Crystal Craft was the first major Virtual Reality club project at San Diego State University. This project lasted the entire Spring 2018 semester. Crystal Craft was developed for Professor Wenwu Xu’s Introduction to Materials class for Mechanical Engineering students as a teaching tool. I oversaw the accuracy of the crystal structures (such as BCC, FCC,… Continue reading Crystal Craft

$50,000+ project (May 31, 2020 update)

Johnson Matthey – Marker Band Length Sorter (on-Going) This is my engineering senior design project (January 2020 to December 2020) at San Diego State University (SDSU) under the Department of Mechanical Engineering. Our project advisor is Professor Alexander Lehman. I created this System Level Diagram SolidWorks drawing of the Final Assembly As I’m typing this,… Continue reading $50,000+ project (May 31, 2020 update)


Marble-ous is a Rube Goldberg machine-like marble color sorter (it’s quite a mouthful!) This was an internship through San Diego Miramar College and the California Space Grant Consortium. We presented our project on August 17, 2017 at NASA Jet Propulsion Laboratory (JPL). Certificates of achievement My main role in the project was coding the algorithm… Continue reading Marble-ous
