Electronics

Turn a desired physical behavior into a justified circuit and an observable verification result. Treat the schematic, components, layout, power source, load, measurement setup, and environment as one system. A plausible schematic or successful simulation is an intermediate artifact, not proof of a working assembly.

Working contract

1. Identify the requested decision: explain, calculate, select, review, diagnose, build, or verify. Produce the artifact needed for that decision; do not demand a full design dossier for a bounded calculation.
2. Record exact component and board identities when device-specific claims matter. Use the manufacturer datasheet revision, package and operating conditions. Separate recommended operation, absolute maximum, typical performance, guaranteed bounds and measured behavior.
3. Model the relevant signal, power, timing and thermal paths. State units, sign conventions, assumptions and corners. Compute a useful conditional result from supplied hypothetical inputs; do not invent missing measurements or guaranteed ratings.
4. Define acceptance before experimentation. Each measurement needs a predicted value/range, instrument configuration, validity limits and a decision it will resolve.
5. Change one explanatory variable at a time when feasible. Preserve the initial symptom and distinguish observation from hypothesis and inference.
6. Before changing wiring, applying power, driving signals or operating connected equipment, confirm the target, scope, and rollback path before acting. Read-only discovery may proceed without confirmation. Obtain the measurement and recovery plan appropriate to the actual energy and fault paths.
7. Stop if the next action exceeds verified device, instrument or isolation limits. Missing high-risk facts require a bounded evidence request, not a guessed command or connection.

Route the work

Load only the references needed for the current decision. Each reference contains assumptions, worked reasoning, failure patterns and acceptance guidance; templates turn that reasoning into reviewable artifacts.
