MISSION INTEL: Each station may have 1–2 participants, with tandem work recommended for safety, where one member probes the circuit and the other logs observations. Teams are provided with two separate circuit boards (either breadboards or pre-fabricated PCBs), each containing intentional faults that prevent proper operation. The challenge runs under a strict 90-minute time limit, and both circuits must be successfully powered on and remain stable at the end for final judging.
