I design embedded hardware, write bare-metal C & FreeRTOS firmware, and build open-source systems from the transistor level up to Linux desktop tooling.
Welcome to my engineering studio and notebook. Here I document my real hardware prototypes—from an ESP32-S3 2.4 GHz Multi-Functional RC Console and a Dual-Core ESP32 16-Track MIDI Synthesizer to a 4WD Autonomous Vehicle and a Standalone Linux Game Launcher written in Rust.
A handheld 2.4 GHz wireless transmitter and embedded control console powered by an ESP32-S3-N16R8 (16 MB Flash / 8 MB Octal PSRAM), nRF24L01+ PA+LNA RF transceiver, dual K-Silver Hall-effect gimbals, and shared SPI2 1.3" ST7789 IPS TFT + MicroSD bus.
A standalone dual-core ESP32 MIDI synthesizer, drum sequencer, and 30 FPS SPI OLED visualizer with a custom Python RLE MIDI-to-C compiler (midi_to_c.py), hardware PCNT rotary encoder, passive melody piezo, and dual active drum buzzers.
A companion 4WD robotic vehicle platform designed to pair with the 2.4 GHz Multi-Functional Controller while exploring closed-loop motor control, telemetry feedback, and autonomous obstacle-avoidance logic.
An all-in-one standalone Linux desktop launcher written in Rust that runs Point Blank (Zepetto / TAM) on Linux with 100% unmodified official CheatBlocker anti-cheat, automated Wine prefix provisioning, and DirectX 9 / DirectX 11 support.
From decoupling capacitors, BJT switches, and SPI bus arbitration up to FreeRTOS tasks and Python/Rust tooling—I study how every layer connects so I can take full ownership of what I build.
