The GIGA R1 WiFi is a powerful, feature-packed board with a large amount of GPIOs and dedicated connectors. Based on the STM32H747XI micro based on the Mbed OS, the GIGA R1 WiFi features 76 GPIOs, a dual-core processor, advanced ADC/DAC features as well as camera & display connectors. It also has a rich USB interface with support for HID via USB-C® and a USB host (keyboard, mass storage) via a dedicated USB-A connector.

![A Useless Rubiks Cube Solver
Why build a standalone Rubiks Cube solver when smartphone apps already exist? Because I wanted a physical, screen-free gadget to play with together with my kids!
This is a fully handheld, offline Rubiks Cube solver powered by an ESP32-S3. It scans the cube using a built-in camera, detects colors with OpenCV, allows manual touch correction via an LVGL UI, and guides you through the solution step-by-step on a 2-inch LCD screen—all without needing a phone, cloud, or PC.

![Just look how satisfying this motion is
I built a real-time gravity particle simulation using an ESP32-S3 and a gorgeous 1.75-inch AMOLED round display (466x466 px).
Watch the square particles react smoothly to every single tilt, driven by a built-in IMU sensor. Gravity. Dictating the flow.

![I Built a Digital Pixelation Device Inspired by Hakusi Katei’s Pixel Cube
Inspired by Japanese designer Hakusi Katei and their stunning Pixel Cube, I created my own interpretation — a digital pixelation device that brings the same analog magic to life in a modern, interactive form.
This device captures real-time input, processes it using OpenCV, and renders a pixelated version on screen. Whats special is that you can interact with it by touch to change the size of the mosaic tiles, creating a playful and emotional visual experience.
As a firmware engineer, Im usually focused on digital code and function — but this project connected me with a more visual, emotional, and analog-like aesthetic.
I’ll continue evolving this project to make it feel even more analog and expressive.

![[On-Device] ESP32 Text-to-Speech Demo with Multi-Language Support (Pico TTS & LVGL Integration)
In this video, I demonstrate my ESP32 Text to Speech (TTS) project, where I integrate Jades Pico TTS component to bring multilingual support to the ESP32 platform. While Espressifs official TTS model currently supports only Chinese, Pico TTS fills the gap, enabling languages like UK and US English, German, French, Italian, and Spanish. The project is built with LVGL for a smooth UI experience. Watch as I show how to convert text to speech, perfect for embedded systems with speaker output.
