Basys-3d

A very basic fixed function GPU/rendering pipeline on a Basys 3 FPGA Development Board, using fixed point numbers for vertice positions and lighting/color calculations
Able to render as many polygons as can fit in RAM at higher than 60 FPS

GitHub Link (VHDL Code)
GitHub Link (Tools for interfacing with the board)

Note: I wrote this contemporaneously with the previous repository, the date of the repository is incorrect.

Vpe Serial Transciever

An implementation of a single wire serial data transmission protocol called "Vpe" or Variable Pulse Encoding, with a variable pulse width set by the length of the first pulse, where the symbols sent are encoded by a certain number of time frames low, followed by a certain number high. The length of the time frame being set by the first pulse in a data frame. Was able to hit the theoretical maximum data transfer rate with this board and design, around 10x slower than the clock rate of the board.

Project Name

Aether Table

Project Description

A modular display system meant to be placed on top of a table for tabletop roleplaying game sessions, used for displaying things like maps, and tokens on top of those maps.
Will automatically reconfigure the display positioning when the displays that are part of it are moved around in relation to eachother, using hall effect sensors and electromagnets.
It will also have a web app for both gamemasters and players to interact with the display, and store character/npc information for ease of access.
In essence, it is bringing the features of a virtual table top onto a physical tabletop.

Proof of concept demonstration

This video shows a demonstration of the aforementioned reconfiguring capabilities of the project using hall effect sensors.

SpaceWarp

I am the lead maintainer of the modloader project for KSP2 known as Space Warp, it is built off of BepInEx, but on top of that provides many KSP2 Specific Utilities for modding. This modloader has been used in the creation of the majority of mods for KSP2.

SpaceWarp.Template Pipelines

I was involved in the creation of the modding template for SpaceWarp, a project that has made it quite easy for anyone to create a repository from the template, and create their own mods. My specific involvement here was the addition of release pipelines for GitHub that automated the process uploading the built mod files and pushing them to SpaceDock, a mod distribution site for KSP1/2.

KSP2 Unity Tools

KSP2Unity Tools is a unity based SDK for creating parts and other assets for KSP2 mods, it also includes a lot of utilities like custom editors for common types, and a build/test pipeline to easily test your mod.

With my work for it for KSP2 Redux, it becomes the fully featured SDK for creating all types of mods, and can test the mods in the editor being able to load mod dependencies in the editor as well.

Patch Manager

Patch Manager is a spiritual successor to Module Manager, allowing modders to patch any JSON definition within KSP2 using a bespoke SCSS based DSL for writing the patches. It is used in many KSP2 mods that need to add stuff to the tech tree or parts or in basically any place.

KSP2 Redux

KSP2 is a comprehensive mod update/overhaul of KSP2 with the aim of bringing the community features that were promised for KSP2 before it was abandoned.

I am one of the leads on this project, my role being to integrate the modloader into the game, which is based off of Space Warp, and to then also update all the modding tools for use with KSP2 Redux, and make them nicer to use.

For example: I have implemented a completely custom mission editor for the KSP2 Redux version of KSP2UnityTools.

KSA Loader

KSA Loader is a very simple harmony based mod injector for the in development game "Kitten Space Agency".

Premonition

Premonition is a Harmony inspired monkey patching library for C# modding purposes. It works using Mono.Cecil to rewrite methods in assemblies before they are loaded by the assembly loader. This provides a distinct benefit over Harmony as it can target many methods Harmony cannot, such as virtual base methods, or inline methods.

Cheese Util Mod

Cheese Util Mod is a mod for a game known as Logic World that provides a lot of utilities for people designing projects in there, like screens and memory storage. It is one of the most used mods for Logic World

TOML Resume

TOML Resume is an ASP.net based server that serves a resume as a static HTML file + CSS built from a TOML file using a view.

CheesyRegex

Cheesy Regex is a completely custom implementation of Compiled Regexes in C# that I wrote, it also has utilities for generating Mermaid diagrams from regexes. It uses the Cheese.IlGen library for C# dynamic IL generation that I wrote

Note: The date of this repository is incorrect, I wrote this in November of 2024.

Cheese.IlGen

Cheese.IlGen is a library for dynamically generating C# IL using a builder pattern, for use with System.Reflection.Emit and dynamic assemblies.

C3Cubed

C3Cubed was a library written in C3 for generating QBE IR code for use in programming language implementation.

Lexi Fantasy CPUs

This is a library for implmenting fantasy CPU emulators in Rust, it currently contains a reference implementation of a 6502 emulator.

Note: The date of this repository is incorrect, I wrote this in April of 2025

Rust 6502 OS

An OS written entirely in 6502 assembly for the project mentioned before this one, it is styled after dos and has fs routines and can load programs off of the disk.

Note: The date of this repository is incorrect, I wrote this in April of 2025

Noodle Processing Unit

The Noodle Processing Unit was an 8 bit computer designed in a game/logic simulator known as Logic World, around October of 2021.

This video shows the Noodle Processing Unit doing the fibonacci sequence in hexadecimal

The noodle processing unit from above

Blocks.Net

Blocks.Net is a C# implementation of a Minecraft Server that I am working on with one other, it is meant to eschew the idea of "vanilla" minecraft and treat the server as a multiplayer game framework.

Cheese Programming Language

The Cheese Programming language is my own compiled programming language that I have been working on and off on in a while

Note: I am currently designing a complete reimplementation, so this repository is quite old.

Cheddar os

Cheddar OS is an x86 operating system that I was writing in C++

FRC

I was a programmer on my highschools FRC team, mostly working with writing and tuning PIDs for the various subsystems.

GTRI Internship

I did an internship with the Georgia Tech Research Institute during highschool, for this internship we worked with a small robotic arm and an arduino, writing a USB serial protocol for it and implementing an inverse kinematics algorithm on it known as FABRIK.
