Chip8-C
A small machine, a deep rabbit hole. A Chip-8 emulator with a C++ frontend, debugger, disassembler, and assembler.
Developer. Maker. Always curious.
James
Kozlowski.
Building software.
Understanding the pieces.
I’m a senior software developer at MinuteBox, working on backend systems with Go, TypeScript, and Google Cloud. Based in Fredericton, New Brunswick.
From low-level details to the bigger picture.A little about me
01 / About
Curiosity is
the common thread.
From embedded software and thermal testing equipment to security products and cloud APIs, I like figuring out how things work—and making them work better.
My background spans hands-on development, leading R&D teams, and troubleshooting systems when the answer isn’t obvious. Today, I build integrations and internal APIs at MinuteBox, and help shape our AI development tools.
Outside of work, that same curiosity turns into emulators, experiments with randomness, and an ever-growing reading list.
Tools I work with
02 / Selected projects
Built to learn.
Shared to explore.
02
Random Number API
Numbers, strings, and UUIDs from a Go API, with secure options for secrets and a separate experiment seeded by public Bluesky replies. The reply-seeded numbers are not cryptographically secure.
03
A little randomness
A Discord bot that brings the Random Number API into chat. A small companion project connecting an experiment to a community.
03 / The path so far
Different domains.
Same drive to build.
Software, systems, and the people behind them.

Notes from the workbench.
Things I’ve built, books I’ve read,
and ideas worth writing
down.
Designing a Wi-Fi Smoker Fan Controller
A first look at the electronics and control strategy for a temperature-controlled smoker blower.
Building Switchboard: Workspaces for AI Coding Agents
Building a control panel for personal agent workspaces, shared skills, and consistent AI workflows.
J{AI}MES — My AI Coding Setup
Experiments with opencode and a personal AI coding workflow.
Zero to Production in Rust
Building along with Luca Palmieri’s guide to production-ready Rust.
Let’s Go & Let’s Go Further
Two books by Alex Edwards that helped deepen my Go skills.
Free Will and Random Numbers
From Reddit comments to public Bluesky replies as seeds.
Building a Chip-8 Emulator in C
From the instruction set to a debugger and disassembler.
05 / Away from the keyboard
Not everything
needs a screen.
Sometimes the best thing to build is something you can hold. Sometimes it’s just a good day outside.
Trails & fresh air
Exploring new paths, getting outside, and staying active.
Wood, metal & making
Woodworking and welding scratch a different kind of creative itch.
A good pour
Exploring whiskey, scotch, and bourbon—and the craft behind them.
06 / Keep in touch
Good things start
with a conversation.
