SensorsI've built an ultrasonic 3d scanner using a phased array emitter. It works like the active phased array radar on modern fighter jets, but with ultrasonic waves.
MoneyI've co-founded Kaktana, a SaaS to create crypto trading bots with no programming knowledge.
RoboticsBallfinder (school project) a robotic arm controlled by the wearer's arm moves + computer vision. When the wearer closes his hand (detected by ECG), the robotic arm tries to find a ball and to catch it using computer vision. The robotic arm is a toy. We had to enslave it with an arduino and H-drives.
AII've built wargames, a game where two AIs compete with each other and advance with a genetic algorithm. (Python)
GraphicspyWireframeRenderer, a complete 3D pipeline with only Numpy and Pygame (2D graphics).
PhysicsWave-Sim a 2D interference simulation to understand phased array beams (the technique used for fighter jet radars) (C++)
Things that flyI've built numerous model planes, and my own quadcopter (stabilization code in C++ included) from scratch when I was 14.
+ many other thingsI invite you to check out my github.
