Engineering Projects & Open-Source Builds

Every project documented here is backed by real hardware on my bench or shipped open-source code on my GitHub—complete with verified pinouts, schematics, build photos, and dedicated slots for upcoming YouTube Proof-of-Concept (PoC) demonstration videos.

Active Hardware & Software Portfolio

All Projects (4)

Rev 0.1 Built → Phase 2 Console Project 01 • Embedded Hardware

Multi-Functional RC Controller (MFC)

A custom 2.4 GHz wireless remote controller and multi-purpose embedded console built around the ESP32-S3-N16R8 and nRF24L01+ PA+LNA transceiver. Currently built as an early Rev 0.1 perfboard carrier and transitioning into a DT-100 (190×137×59 mm) desktop console with dual K-Silver Hall-effect gimbals and a 1.3" ST7789 IPS TFT display.

  • ESP32-S3-N16R8
  • ESP-IDF v5.2.2 (C99)
  • nRF24L01+ 2.4 GHz RF
  • Hall-Effect Joysticks
  • ST7789 TFT + MicroSD
  • KiCad Schematic

Includes on page: 3 early prototype build photos, full KiCad SVG schematic, verified ESP32-S3 GPIO pinout, Phase 2 DT-100 BOM, and 🎬 YouTube PoC Video Placeholder.
