My engineering philosophy

As a mechatronic engineering student, I am continuously developing an engineering mindset centred on practical problem-solving, innovation, and efficient design. I enjoy transforming old or broken components into functional systems, combining resourcefulness with sustainability-focused thinking. With over five years of hands on experience in CAD design, CNC manufacturing and 3D printing, including designing and manufacturing various automotive components, I focus on manufacturability, cost effectiveness, and rapid prototyping. I am driven by questions such as how to optimise designs within constraints, reduce complexity, and improve performance, allowing me to develop practical and well engineered solutions.

About Me

Hi, I’m Kyan, a mechatronic engineering student driven by a passion for designing practical and innovative solutions. My journey began with a curiosity about how things work, which has grown into a hands on approach to building, prototyping, and problem solving. Based in Sydney, Australia, I combine creativity with engineering fundamentals, focusing on efficient design, real world functionality, and continuous improvement in every project I undertake.

My favourite projects

Dive into my portfolio to see a a detailed selection of my completed engineering projects. Each entry not only showcases the final outcome but also details the design thinking and technical challenges overcome along the way.

Wheel Stands

I designed and built these custom wheel stands from concept to completion for work, starting with modelling in Fusion 360 and finishing with CNC milling from 6061 aluminium. The design incorporates stainless steel crossbars to safely support the full weight of a vehicle while maintaining a clean and purposeful aesthetic. Seeing the project evolve from an idea into a physical product was incredibly rewarding and reinforced my passion for hands on engineering. After achieving a mirror polished finish on the front face, I used a fibre laser to engrave the company logo, adding a professional touch. I’m especially proud of how this project balances structural strength, precision manufacturing, and visual detail.

Converted Alternator E-Bike

My custom e-bike project repurposes a broken automotive alternator as a brushless motor, with modified internals, motor control integration, a new drivetrain and a custom mounting system. This project proposed a variety of challenges to overcome so it was incredibly satisfying to take the first ride. I had to remove the voltage regulation circuitry from the alternator and supply a voltage to the rotor with a step down transformer, effectively turning it into a permanent magnet, I then was able to hook up an e-bike speed controller to the coils of the stator, allowing me to power the now "alternator motor" with a throttle. It then took some effort to develop a new drivetrain system, ditching the chain and sprocket for a pulley and belt system, allowing me to fine tune the torque and speed settings. In the end I was left with a fully functioning (and fun) e-bike, making use of recycled and 3D printed resources for a fraction of the price of a standard conversion kit.
