NielsN5/README.md

Hi, I'm Niels 👋

Engineering student who builds things that work in the real world: hardware prototypes with sensors, firmware and 3D-printed parts, lightweight structures designed with CAD, FEA and topology optimisation, and machine-learning tools that make models easier to understand. Currently based in Sydney.

🏆 Achievements

  • 1st place of 60 teams and People's Choice Award, UNSW Build-a-thon 2026 (RAMSoc × WIT with UNSW Founders), with SeedStick

Featured projects

SeedStick prototype

SeedStick

Hand-held planting tool for land restoration: checks the soil, sets every seed ball at the same depth and logs each one. 🏆 1st place and People's Choice Award.

ESP32 C++ 3D printing sensors 		Quadcopter frame with topology-optimised arms

Drone

Quadcopter frame redesigned with support-free topology optimisation and FEA: arms 1.78× stiffer with 32–35 % lower peak stress, printed in PETG without supports.

Fusion 360 FEA topology optimisation Betaflight 		data-pruning-viz dashboard

data-pruning-viz

Research project at Fraunhofer IPA / University of Stuttgart: a tree-based visualization of interaction effects between training examples for safer data pruning.
