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:

1. Normalize the topic string (lowercase, trim whitespace)
2. Match against each skill's triggers array from chipset.yaml
3. If multiple skills match, prefer the most specific match (longest matching trigger string)
4. Return the matched skill's module field (e.g., "01-the-circuit")
5. 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
6. 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.
