Hi, I'm Isaac Adjei (Zaccess) πŸ‘‹

I'm an Electronic Engineering and Computer Science student at Aston University, Birmingham. I build open source educational tools, embedded hardware systems and full-stack platforms - and I publish everything.

What I'm working on

Featured

git-unlocked - The most complete free and open source Git curriculum available. 12 sections, 217 files, covering GitHub, GitLab, Bitbucket, Azure DevOps, Gitea, Forgejo and Codeberg with Windows, Mac and Linux examples throughout. MIT licensed. Published on Zenodo.

Phaemos - Full-stack IoT predictive maintenance platform: embedded firmware for ESP32, STM32, Arduino and Pico 2W; sensor telemetry pipeline; FastAPI backend with PostgreSQL, Redis and ML anomaly detection; TypeScript dashboard with real-time charts, multi-tenant auth and alert management.

Hardware and embedded

AVR-Zac - Bare-metal C on ATmega644P. State machines, interrupts, PWM, ADC, a reaction-time game and a Tetris melody - register-level, no Arduino abstraction.

NeoPixel LED Cube - A 4x4x4 interactive WS2812B LED cube on Arduino Uno with four animation modes, LDR adaptive brightness and physical button controls.

Two-Stage Audio Amplifier - Line-level to 8 Ξ© speaker amplifier built around a TL071 op-amp and OPA551 power buffer, simulated in Proteus SPICE, verified on breadboard and implemented as a custom PCB.

Learning and coursework

AWS AI Practitioner - Full notes and project work for the Udacity AWS AI Practitioner Challenge.

Competitive Programming - LeetCode, NeetCode and Codeforces solutions, templates and notes.

Coming soon

There is a lot more in the pipeline - more open source tools, more hardware builds and more educational content across both software and embedded systems. Follow or sponsor to stay in the loop.

Why sponsor me?

  • Keep git-unlocked free, maintained and growing for learners worldwide
  • Fund hardware components, PCBs and electronics for embedded builds
  • Support more open source educational content across software and hardware
  • Help a student dedicate more time to community work outside coursework
