johanv.xyz, my chill website
Hi, I'm Johan Vandegriff, and this is johanv.xyz: my new, awesome, spectacular, and chill website! Here's a random interesting fact about me:
My siblings and I have been making and filming little skits and stories since we were young. We used to edit them on Windows Movie Maker (yikes!), but now I use Kdenlive and Shotcut.
This is a drawing I made of the Erasable Inc. improv group at the University of Maryland (UMD) after their 24-hour show.
This video is for a propsed research project for Gemstone at UMD. I ended up joining another project instead, but I still have the initial version and plan to make it into a product someday.
Here are some of my projects:
- ArduinOLED - A handheld Arduino-based platform to create games, test equipment, and other projects. Learn how to make and use it!
- HexaGame - A handheld multi-game system that consists of a hexagon of LEDs with buttons surrounding it, as well as a hex-shaped dpad.
- GAMES (Glamorous Automatic Multi-game Emulator System) - A tiny Arduino game system with a 3x3 LED screen and 4 buttons.
- Calculator - A calculator you can run in the terminal.
- Quest Game - A roguelike game I am working on.
- asocialsafety.net (archived) - The website for a hackathon project my friends and I made.
- My Config Files - Some files with settings the way I like them, with descriptions.
Here's a snippet from a quintessential blog post of mine:
Log.e() – Tales from the electron Volts
An account follows of the myriad of adventures I have had with the electronVolts. My aim is that the narrative shall be as accurate as possible and will serve useful in reference during future events.

We were visited by a band of rookies. They do not perceive the insurmountable tasks that lie ahead of them. I attempted to affright them by disclosing to them the monster that is The Code, but alas, they took an interest in this beast. I fear there is no way to warn them; their days ahead appear grim.
The Great Git attacked our code today. I researched its weaknesses in the Archives of Google and found individuals who were in a similar predicament. Armed with this knowledge, we were able to send it howling back from whence it came.
NASA GSFC Internship
I fixed bugs in C code for NASA’s core Flight System by writing unit tests on a CentOS Linux virtual machine (using VirtualBox). To help write unit tests, I wrote some bash scripts to generate skeleton functions, then filled them in manually with code to test each case. At the end of the summer, I created a poster and presented it at a lab-wide showcase day.
