Building circuits · Coding firmware · Designing PCBs · Shipping intelligent hardware
This is the ultimate Hitootronic electronics portfolio experience — showcasing embedded systems, robotics, IoT devices, and experimental electronics built in a futuristic engineering interface.
The site now has a stronger project system: a spotlight area, quick capability chips, search, category filtering, and premium cards that match the original uploaded template style.
Microcontroller logic, communication protocols, state machines, sensor drivers, and real-time control flows.
Schematic design, routing, connectors, power stages, bring-up testing, and prototype revision cycles.
Wi‑Fi, Bluetooth, MQTT, cloud dashboards, telemetry channels, and real-time control interfaces.
Panels, smart control loops, relay logic, sensors, actuator control, and safer system operation.
A custom ESP32-based robot controller with captive portal Wi‑Fi onboarding, real-time servo commands over WebSocket, OLED facial animation rendering, and a React Native mobile companion. Designed to remove hardcoded credentials while making the robot feel responsive, expressive, and production-ready.
6-DOF robotic arm with PID servo control, inverse kinematics firmware, Bluetooth command mode, and a custom driver PCB for cleaner motion performance.
IoT energy monitoring device using INA226 sensing, ESP8266 connectivity, and a dashboard for live voltage, current, and threshold-based alerting.
Long-range node network built around SX1276 LoRa radios and STM32 devices for low-power agricultural sensing over multi-kilometer distances.
Custom 4S battery management board with balancing, protection, current monitoring, and pack health logic designed for reliable lithium systems.
STM32F4 real-time FFT analyzer with a custom audio front end, AGC stage, and LED matrix output for vivid band visualization.
A Raspberry Pi control hub bridging Zigbee, Z-Wave, and Wi‑Fi devices with relay outputs, sensors, and custom expansion hardware.
Reliable load switching panel with safety interlocks, control relays, status indicators, and enclosure-focused practical design.
Sensor-rich edge device that measures conditions, pushes telemetry, and drives outputs automatically based on adaptive threshold logic.
Custom motor control platform with PWM regulation, feedback loop tuning, fault response, and driver stage optimization for cleaner motion.
The skills zone keeps the same template DNA, but now feels more complete and premium for a serious electronics portfolio.
Hitootronic is built around one idea: make electronics projects feel as advanced online as they are on the workbench. From custom PCBs and firmware to user interfaces, automation logic, and final enclosures, the goal is full-stack hardware storytelling.
This site is made for embedded systems, robotics, connected sensors, control electronics, lab experiments, and practical products. Every section is shaped to help visitors understand not only what was built, but how it works and why it matters.
The new version adds stronger hierarchy, richer project presentation, search and filter behavior, a bigger hero lab scene, and a more premium visual system while staying faithful to the original uploaded neon template.
A strong engineering portfolio shows process, not only outcomes. This section helps visitors trust the way you build.
Capture the real need, electrical constraints, interfaces, safety concerns, and target performance before touching the hardware.
Map the architecture using schematics, block diagrams, components, protocol decisions, and the firmware plan.
Bring up the board, debug communication, tune control loops, validate measurements, and find the weak points fast.
Improve the build, add polish, show results, explain lessons learned, and turn the project into a compelling case study.
Still loyal to the uploaded template, but now expanded into a richer portfolio system with more depth and better presentation power.
Visitors can search by project name, technology, or type. That makes the portfolio feel more real and more useful.
The hero is no longer only text. It now feels like a live engineering dashboard with chips, traces, waveform output, and system cards.
About, process, and mission sections now support the projects, helping clients or recruiters understand your work style.
This section is ready for real collaboration details. Replace the sample links with your actual email, GitHub, YouTube, or LinkedIn.
