Start the Open Source Data Center Technician track with the physical fundamentals of a data center floor: racks, power paths, cooling, network cabling, switches, redundancy, alarms, safety, and technician troubleshooting.

A robotics technician’s first job is not making the robot move. It is knowing when the robot must not move, what can still move after a stop, and what conditions must be proven before a person enters the hazardous space. This is OSRTC.001, the first lesson in the Open Source Robotics Technician Certification track. It…

Learn the engineering foundations of robot motion: coordinate frames, joint space, task space, homogeneous transforms, forward kinematics, inverse kinematics, TCPs, singularities, and practical fault isolation.

Semiconductor engineering starts with one idea: electrical behavior can be designed by controlling which energy states electrons can occupy and how many mobile charge carriers exist. This is OSSEC.001, the first lesson in the Open Source Semiconductor Engineer Certification track. It builds on the technician-level cleanroom and ESD foundation from OSSTC.001 and moves into the…

Start the Open Source Semiconductor Technician track with the fab fundamentals every technician needs: cleanrooms, contamination control, wafers and FOUPs, electrostatic discharge (ESD), electrostatic attraction (ESA), grounding, gowning discipline, and safe technician behavior around semiconductor equipment.

Learn how C++ pure virtual functions create abstract base classes, why abstract classes cannot be instantiated directly, how derived classes implement required behavior with override, and how this pattern creates a common interface.

Learn how temperature switches and thermostats convert temperature changes into electrical contact changes, including setpoint, differential, sensing bulbs, bimetal switches, NO/NC contacts, heating/cooling logic, and basic troubleshooting.

Learn how circuit breakers and fuses protect electrical systems from overloads and short circuits, how fault current and interrupting ratings matter, and how selective coordination keeps a downstream fault from unnecessarily shutting down healthy upstream equipment.

Learn how the Windows net file command lists files opened remotely through shared resources, how to read file IDs and locks, how net file connects to net session and SMB, and how to close a specific remote open file safely.
