David Montero Crespo 0ef656849d fix(spice): every overlay board was solved as a 5 V Arduino
BOARD_PIN_GROUPS is keyed by the BoardKind union, so a board registered by the
overlay could never appear in it and fell through to `default` — 5 V, ground
pads named GND/GND.1/GND.2, supply pads named 5V/VCC. Every RP2350 and
ESP32-family pro board is a 3.3 V part whose supply pad is called 3V3, so the
netlist powered it from the wrong rail and did not recognise its supply pad at
all. Nothing errors; the numbers are simply wrong.

Caught on the Pimoroni Pico Plus 2 W: a potentiometer across 3V3 and GND read
2.50 V at half travel instead of 1.65 V, because the divider was solving
against a 5 V rail. The same 1.5x error was sitting under every LED current,
pull-up and divider on every pro board.

boardPinGroupFor() consults the pro registry before falling back, and a board
declares its pads through ProBoardDef.power. The OSS table is untouched, so no
existing board changes behaviour.

Found while wiring the ADC seam: enabling the SPICE analog path for a pro board
is what finally made the wrong rail visible.

David Montero 44782a419a fix(spice): per-voltage supply rails — VIN/5V no longer clamped to the 3.3V logic rail
Board supply pins split into the main logic rail plus aux rails by real
voltage (ESP32/XIAO VIN,5V -> aux_rail_5 at 5 V; 5V-Arduino 3.3V pin ->
aux_rail_3v3; Pico VBUS/VSYS -> 5 V). An external 5 V supply wired to VIN
used to read 3.3 V (ideal vcc_rail source clamped the whole net — customer
isolated it with a voltmeter). Aux rails join positiveSourceNets and the
relay nominal-voltage check; the voltmeter and hover overlay read them.
Also: ratings entry for the 4-pin ssd1306-i2c-4pin (supply pin VCC) and a
VCC alias on the 8-pin entry, so its power check works at all.

David Montero 4e20d03f4c feat(sim): P1 over-voltage for boards + electrolytic capacitors
Extends the over-voltage rule to the two cases the previous slice deferred:

- Boards (ESP32 / Pico / Arduino / ...): a board's supply pins all collapse to
  the self-driven vcc_rail net, so an external source on them makes the .op
  singular rather than readable. Added a graph-based check (runs before the
  solve): if a power source is wired to a board supply pin and its nominal
  voltage exceeds that pin's rating, warn. Threaded boardKind into
  BoardForSpice so the verifier can look up the board rating.
- Electrolytic capacitors: new `voltage` rating property (select, default 25V,
  on capacitor-electrolytic + cap-elec-* presets, via component-overrides +
  regenerated metadata). The verifier reads the DC voltage across the +/- pins
  and warns on over-voltage (vent/burst) and on reverse polarity (a polarized
  cap wired backwards). Defaults to 25V when the property is unset.

Tests: 9V battery -> ESP32 VIN warns, 1.5V doesn't; 24V across a 16V cap warns,
5V across a 25V cap doesn't; reverse-biased cap warns. All real-ngspice.

David Montero Crespo 212ecd1bcb refactor: rename components and update prefixes to 'velxio-' for consistency
- Modified the index file to reflect the new naming convention for Velxio components.
- Changed JSX declarations to use 'velxio-' prefix for various components.
- Updated component overrides to replace 'wokwi-' with 'velxio-' for logic gates and other components.
- Adjusted SVG generation script to use 'velxio-' prefix for BMP280 and Raspberry Pi components.
- Marked submodules as dirty in QEMU and RP2040 libraries.
- Added .prettierignore and .prettierrc.json for consistent code formatting.
- Introduced InstrumentComponent with support for Voltmeter and Ammeter, including pin information handling.

David Montero Crespo 993a25390c feat: add passive component presets and custom elements
- Implemented a script to inject passive-component preset variants into `scripts/component-overrides.json`, including resistors, capacitors, and inductors with custom names and thumbnails.
- Added a new custom element `<wokwi-capacitor-electrolytic>` representing a polarized aluminum-can capacitor with appropriate SVG representation.
- Updated metadata generation to accommodate new component names and thumbnails for better user experience in the component picker.
- Marked submodules `qemu-lcgamboa` and `rp2040js` as dirty to reflect local changes.

David Montero Crespo 9cc9cfebd6 Add end-to-end tests for ammeter, voltmeter, and capacitor charging behavior
- Implement `ammeter-waveform.test.ts` to validate AC readings from a sine wave source.
- Create `capacitor-charge-transient.test.ts` to test the charging response of an RC circuit driven by a microcontroller pin.
- Introduce `esp32-rectifier-integration.test.ts` for testing rectifier behavior using QEMU and ESP32.
- Add helper functions in `esp32RectifierE2E.ts` for the rectifier test harness.
- Develop `voltmeter-waveform.test.ts` to ensure correct AC and DC readings from a sine wave source.
- Implement unit tests for waveform statistics in `waveform-stats.test.ts` to validate RMS, mean, peak, and interpolation functions.

David Montero Crespo 137f9ab0a0 Add tests for serial batching and spice rectifier functionality
- Implement `serial-batching.test.ts` to verify the behavior of `createSerialBatcher`, ensuring it coalesces multiple appends into a single flush, preserves byte order, and groups by board.
- Create `spice-rectifier-integration.test.ts` to test the end-to-end functionality of the Half-Wave Rectifier example, covering the entire simulation pipeline from input building to circuit solving.
- Add `spice-rectifier-live-repro.test.ts` to reproduce a live-app failure scenario, tracing through each layer of the simulation to identify potential failure points.
- Introduce `spice-signal-generator-tran.test.ts` to validate the behavior of the signal generator and ensure correct analysis type switching based on circuit components.
- Establish `serialBatcher.ts` to implement a batching mechanism for USART output, reducing the frequency of store updates and preventing React's maximum update depth error.

davidmonterocrespo24 ed9911dcc3 feat: electrical simulation via ngspice-WASM (eecircuit-engine)
Adds full SPICE-accurate electrical simulation to Velxio, behind a lazy-
loaded ⚡ toolbar toggle. Arduino / ESP32 / RP2040 sketches now co-simulate
with real analog behaviour: correct voltages on wires, real I–V curves on
LEDs, working potentiometers, NTC thermistors read by analogRead(), PWM
driving RC filters, transistors, op-amps, diodes, MOSFETs, etc.

Engine: eecircuit-engine (ngspice compiled to WebAssembly). Main bundle
stays at 2.4 MB; the 20 MB SPICE chunk only loads when the user activates
electrical mode. Disabled at build time via VITE_ELECTRICAL_SIM=false.

Frontend additions:
- simulation/spice/: SpiceEngine wrapper + lazy entry, NetlistBuilder with
  UnionFind over wires, componentToSpice mapping (24 metadataIds incl.
  real part numbers: 2N2222, 2N3055, BC547, IRF540, 2N7000, 1N4148,
  1N4007, 1N4733, LEDs, NTC, op-amp ideal), CircuitScheduler with
  debounced coalescing, AVRSpiceBridge for quasi-static co-simulation.
- store/useElectricalStore: Zustand slice, feature-flag aware.
- components/analog-ui/: ⚡ toolbar toggle + SVG voltage overlay.
- components/components-instruments/: Voltmeter, Ammeter probes.
- 62 tests (spice-*, netlist-builder, component-to-spice, instruments).

Sandbox (test/test_circuit/): 47-test validation sandbox that proved
the approach (hand-rolled MNA baseline + ngspice pipeline) before
porting to the app. Kept as reference.

Docs: docs/wiki/circuit-emulation-*.md (13 engineering pages covering
architecture, solvers, components, AVR bridge, gotchas, performance,
integration plan, API reference, appendix) + electrical-simulation-
user-guide.md (end-user facing).

Reference plan: test/test_circuit/plan/phase_8_velxio_implementation.md
