Custom ESP 32 Devboard

I will make an ESP 32 s3 wroom dev board. This is inspired by the RP2040 guided project, BUT I am using ESP 32, as ESP 32s have a lot more functionality and IO.

Landing a Rocket Like SpaceX, by Nimish Nijhawan; Bedroom Engineering

For this project, I will design and build a rocket capable of vertical launch followed by a controlled, propulsive landing. To accomplish this, I will develop a custom ESP32-based flight computer and implement a quaternion-based attitude estimation system for accurate three-dimensional orientation tracking. I will also design and tune a closed-loop guidance and control system to actively stabilize and steer the vehicle throughout flight and landing. In addition, I will create a physics-based simulator in Python—developed from first principles rather than “vibe coding”—to model the rocket’s full flight profile. This simulator will be used to analyze vehicle dynamics, validate control logic, and tune the control loop parameters, enabling reliable and repeatable propulsive landing performance.

Nimish's Macropad

I am making a macropad, to practice soldering, and to learn PCB design.
