majiayu000 Electronics Educational Pack
Comprehensive electronics curriculum grounded in The Art of Electronics (Horowitz & Hill, 3rd ed., 2015). Covers 15 modules across 4 tiers, from Ohm's law through PCB design, with interactive labs powered by MNA circuit simulation and digital logic simulation.
Routing
Given a user topic, this skill routes to the appropriate module by matching trigger keywords against the 14 domain skills defined in chipset.yaml.
routeToModule(topic: string): string | null
Accepts a topic string (user query or keyword) and returns the target module directory name, or null if no match is found.
Algorithm:
- Normalize the topic string (lowercase, trim whitespace)
- Match against each skill's
triggersarray fromchipset.yaml - If multiple skills match, prefer the most specific match (longest matching trigger string)
- Return the matched skill's
modulefield (e.g.,"01-the-circuit") - For
industrial-and-applied(multi-module skill), return the best-fit module from[13-plc, 14-off-grid-power, 15-pcb-design]based on the specific trigger matched - If no trigger matches, return
null

Learning Progression
The curriculum follows a 4-tier pipeline, where each tier builds on the previous:
Tier 1 (Foundations) -- Modules 1-3 Voltage, current, resistance, passive components, and AC signals. No active devices. All labs use passive circuits only. Safety: Annotate mode.
Tier 2 (Active Devices) -- Modules 4-7 Semiconductors (diodes, transistors), op-amps, and power supplies. Introduces nonlinear behavior and active circuit design. Safety: Gate mode for higher voltages.
Tier 3 (Digital & Mixed-Signal) -- Modules 7A, 8, 9, 10 Logic gates, sequential circuits, data conversion, and DSP. Bridges analog and digital domains. Safety: Annotate (logic) to Gate (mixed-signal).
Tier 4 (Applied Systems) -- Modules 11-15 Microcontrollers, sensors, PLCs, off-grid power, and PCB design. Real-world applications combining all previous tiers. Safety: Gate to Redirect mode for industrial/high-voltage.
