# 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) ## Supported Components ### Microprocessors & Memory | Component | Pins | Description | |-----------|------|-------------| | W65C02S | 40-pin DIP | 8-bit microprocessor with 16-bit address bu

What does the legacy-circuit-mockups skill do?
Generate breadboard circuit mockups and visual diagrams using HTML5 Canvas drawing techniques. Use when asked to create circuit layouts, visualize electronic component placements, draw breadboard diagrams, mockup 6502 builds, generate retro computer schematics, or design vintage electronics projects. Supports 555 timers, W65C02S microprocessors, 28C256 EEPROMs, W65C22 VIA chips, 7400-series logic gates, LEDs, resistors, capacitors, switches, buttons, crystals, and wires.
How do I install it?
Run `npx skills add github/awesome-copilot --skill legacy-circuit-mockups --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From github/awesome-copilot, a repository with 37,432 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
