Unnamed Dice Project

unity c_sharp

A quick proof of concept for a Stake-like game, loosely inspired by the Japanese Chinchirorin.
I did all the programming and design.

More of this project

This project was developed in Unity using an orthographic camera and unlit shaders to achieve a 2D-like visual style. While the overall scope wasn’t complex at all, getting the dice physics to feel just right presented some challenges. The most difficult part was ensuring that the dice always landed facing the camera to maintain clarity and visual consistency.

Other Projects

RobotArm

python fusion modbus

A robotic arm demo for an Autonics conference, mostly 3D printed and designed by myself. I also developed the custom control software, assembled the physical control board, and implemented communication with the PC via an RS485 bus using the Modbus RTU protocol.

LeapMiceGemini

c

A small desktop utility that allows you to control the mouse pointer using a Leap Motion device on Linux systems running X11.

MollyPlayback

c sdl miniaudio

A minimalistic audio player built for manual transcription, written in C using SDL3 and miniaudio. It works with a custom foot pedal I also developed (hardware and software).

You can check out the player, pedal firmware and schematics, and the simplePS2 framework

MicroUI

c

I forked Microui, the popular minimalist immediate-mode UI library written in C, and added support for individually resizing the text of UI controls

MICROUI_LOGO

Xdo

unity

I forked Xdo, a small utility for performing actions on X11 windows in Linux from the terminal, and added full support for executing all commands via standard input.

LittleBuild

unity

I created LittleBuild, a small Python tool for compiling C projects, designed as an ultra-minimalist replacement for make, since I often find make’s syntax a bit cryptic for my own taste.
