# Zi Hon's Portfolio Hey, I'm Yew Zi Hon. I hold a Diploma in Mechatronics and Robotics Engineering. I am currently studying Mechanical Engineering at Nanyang Technological University. ## About me My interests are 3D printing, mechatronics and electronics. I have completed multiple hands-on projects, gaining experience across mechanical, electronics, and programming domains. ## Projects ### Data collector - Final Year Project - NTU The data collector for marine application is a final year project with DSO national laboratories. It involved integrating mechanical systems with electronics and embedded programming. I designed the system architecture and implemented the firmware using C on an STM32 microcontroller. Many differnet domains are involved in this complex project, I have gained valuable experience in integrating the various complex systems of the data collector.  ### Ball collector The ball collector project allowed me to integrate the mechanical, electrical, and programming skills that Ive learned throughout my course. I gained valuable experience working with others.   ### Food 3d printing My team and I developed an food 3D printer based on a syringe-pump paste exturder. This competition took place in Hanoi and Incheon. My team achieved second place in this competition.   ### Image plotter This project plots an image using a old repurposed 3D printer.   ### Piano player This project is a personal project that I worked on. It uses servo motors to press down on the piano keys. Motors are driven by a pwm driver and controlled by a micro controller.  **A close up of the mechanism**  **The microcontroller controlling the piano**  <iframe width="420" height="315" src="https://www.youtube.com/embed/NR8rGSLQnuk"> </iframe> <iframe width="420" height="315" src="https://www.youtube.com/embed/1FPYqu8Atf8"> </iframe> [View the project](https://www.printables.com/model/493973-melodymaster-3000-techno-piano) --- ### Plastic and wax machining To experiment with recycling old PLA plactic, a material commonly used for 3d printing.    --- ### Stepper motor music Turns the annoying stepper motor noise into music.  <iframe width="420" height="315" src="https://www.youtube.com/embed/JKKd53B_RKY"> </iframe> [View the project](https://www.printables.com/model/493967-the-nema-ensemble) --- ### Autonomous vehicle - Final Year Project - Poly My team team and i designed and prototyped an autonomous guided vehicle. **CAD design of the vehicle**  **CNC milling**   **wiring**    **Mechanical**    **Vehicle manual control test** <video autoplay muted loop><source src="/assets/fyp/moving.mp4" type="video/mp4"></video> --- ### Melodica player This is the capstone project for a module that I have taken: Further Design and Fabrication. Inspired by the piano player. **Front**  **Menu navigation**  **PCB design**  **Microcontroller programming**  **Integration**   [View the project](https://yewzihon.github.io/EP1001/finalPro.html) --- ### LED sign The LED sign was a CCA project assigned to us. Neopixel LEDs were used to light up the sign and provide various lighting effects. **led sign** <video autoplay muted loop width="100%" height="auto"><source src="/assets/ledSign/speye.mp4" type="video/mp4"></video>     --- ### Electric discharge machining Exploring electric discharge machining (EDM) is a personal project. I have experimented with a drill/sinker EDM. **EDM drilling head**  **Hole being brilled with a brass electrode**  **EDM drilling in progress** <video autoplay muted loop width="100%" height="auto"><source src="/assets/edm/drilling.mp4" type="video/mp4"></video> **End result**  --- ### Pen plotter **Drawing a rabbit**  <video autoplay muted loop width="100%" height="auto"><source src="/assets/plotter/rabbit.mp4" type="video/mp4"></video> --- ### CNC router **Milled PCBs**  **Machining medium density fiberboard** <video autoplay muted loop width="100%" height="auto"><source src="/assets/cnc/cnc.mp4" type="video/mp4"></video>
