Deriving the nonlinear equations of motion for a pendulum on a cart using Lagrangian mechanics, then simplifying and linearising around the inverted equilibrium to arrive at a state-space model ready for LQR control.

With 3D printing technology becoming more accessible than ever, the question "Which printer should I buy?" is being asked more frequently. I recently came up with a simple analogy to help guide newcomers - comparing 3D printer brands to the "Big Three" operating systems.

As of January 1, 2024, the implementation of Remote Identification for Drones (RID) has become mandatory for Unmanned Aircraft Systems (UAS) operating in both the specific and open categories (except for drones weighing less than 250 grams).
