      A few months ago, I chanced upon a video that demonstrated a commercial Furuta Pendulum design used to teach control theory at the university level. As someone who is always itching to try a new reinforcement learning (RL) project, this felt like the perfect challenge to apply RL to a... [Read More]

      During my 1st year summer term, I took part in a European regional competition, where 32 teams from all over the continent designed and coded algorithms to play a tower defence game called Terminal. Our algorithms were pitted against each other at the end of the week-long competition, where my... [Read More]

      During my internship at HOPE Technik, I was enamored by the CNC machines in the workshop. Something about the speed, precision and capabilities of these machines piqued my interest greatly. Naturally, I had to build one for myself! A project that took over 2.5 months to materialise, it can be... [Read More]

      So, My 3D printed Smart Wallet broke :cry:. I always appreciated that it integrated cards and coins in such a sleek and nifty way (boo to money clips). The design, however, was greatly limited by the pure FDM (Fused Deposition Modeling) approach. Since I was interning at HOPE Technik, I... [Read More]

      As a team of 4 hackathon newbs, Hack & Roll was an exciting opportunity for me and my team to put our development skills to the test. As one of our first full stack projects ever, it was not surprising that we didn’t perform spectacularly. However, I’ve picked up many... [Read More]
