Magnet Free-Fall Experiment
Mark 5A
The Mark 5A magnet free-fall object consists of a Mark 5 3D printed plastic front shell, and a back shell with 45 degree taper, 10mm height, and 25mm length fin size, with a hole in center back for a fishing line to fit through with a knot on the inside, all for the purpose of being held by two electromagnetic solenoid coils for a computer controlled drop, eliminating the hand method that had been used to date. The electronics used are a Arduino Nano 33 BLE Rev2, Adafruit BNO055 IMU, PowerBoost 500 Basic, a 3.7V Lipo 250mAh Battery, and a Control, NS/NS, and SN/SN magnet object.

Overview
The purpose of this experiment was to test the Mark 5 shell, slightly modified with a piece of string coming out of the back shell to squeeze between two solenoid coils which are controlled by an Arduino in order to create a computer controlled drop instead of hand dropping as has been done in the past.
