SKILL.md

HTML5 Canvas breadboard circuit mockups for retro computing and vintage electronics projects.

Supports 40+ components including W65C02S microprocessors, 555 timers, 28C256 EEPROMs, W65C22 VIAs, 7400-series logic gates, and passive components like LEDs, resistors, and capacitors

Renders circuits on a 20px grid system with component rotation, wire color coding, and pinout reference tables for accurate layout visualization

Includes step-by-step workflows for common builds: LED circuits, 555 astable oscillators, and full 6502 microcomputer layouts with address/data bus wiring

Bundled reference files provide complete pinout specifications, timing formulas, resistor calculations, and troubleshooting guides for all supported components

Legacy Circuit Mockups

A skill for creating breadboard circuit mockups and visual diagrams for retro computing and electronics projects. This skill leverages HTML5 Canvas drawing mechanisms to render interactive circuit layouts featuring vintage components like the 6502 microprocessor, 555 timer ICs, EEPROMs, and 7400-series logic gates.

When to Use This Skill

User asks to "create a breadboard layout" or "mockup a circuit"

User wants to visualize component placement on a breadboard

User needs a visual reference for building a 6502 computer

User asks to "draw a circuit" or "diagram electronics"

User wants to create educational electronics visuals

User mentions Ben Eater tutorials or retro computing projects

User asks to mockup 555 timer circuits or LED projects

User needs to visualize wire connections between components

Prerequisites

Understanding of component pinouts from bundled reference files

Knowledge of breadboard layout conventions (rows, columns, power rails)
