An Arduino Uno R3 based device that automatically switches on the light at a programmable time to help people wake up at the right time through exposure to bright lights right before and during wake up. It uses a DS1307 RTC Clock Module for keeping accurate track of time for a longer duration, although after long duration usage, the clock may shift requiring resetting it to the current time through re uploading the files in the specified order. The actuator is a SG90 Micro Servo although any servo that can be controlled using PWM is compatible, just note that larger servos may cause brownouts as the servo is directly powered by the Arduino Uno, although you may alter this as needed.
An infill generator for FDM 3D prints that optimizes the density of the infill for the load's the part will experience to improve the performance of the part while minimizing mass.
A Python based Inverted Pendulum on a Cart simulation that uses different forms of control for keeping the pole upright.
6 Axis Tendon Actuated Robotic Arm for Low Mass-moment of Inertia leading to higher end effector acceleration.
