Team Member, Formula Sae Electric 2023
College Station, Texas, United States
Design cycle: 1 yearTime commitment: 10-25 hours/weekAs an electronics subteam member, designed low voltage system circuits to ensure driver safety and normal function of car.- Used CAD to design custom circuit boards and selected components while considering simplicity, cost, weight, and size.- Applied troubleshooting skills to detect faults in induvidual boards, wiring harnesses, and the full car.- Presented design decisions to the team, justifying choices and receiving input, while also giving feedback to others.- Integrated with other subteams' designs to support all sensor/controller interaction.- Assembled boards with SMD components by hand-soldering and reflow oven.Responsible for design, testing, manufacturing:Fault latching circuit- Acts as a part of the high voltage Shutdown Circuit, detecting fault or disconnection of critical safety devices. Required by rules, tested by FSAE judges.Dashboard circuit and waterproof housing- Displays faults of above circuit and contains vehicle start button. Required by rules, tested by FSAE judges.Activation Sequence circuit- Receives start button, brake, and shutdown circuit input, and sends enable signal to motor controllers when specific conditions are met. Triggers a Ready To Drive Sound when active. Required by rules, tested by FSAE judges.Data Aquisition CAN-BUS- A serial communication protocol that allows fast transmission of sensor and status data between nodes. Fully designed all message IDs and data packaging.Partially responsible for design of full-car wiring architecture and manufacturing of the vehicle harness.
