Classroom Workbench

Drop gate primitives (NAND, AND, OR, NOT, XOR, BUFFER, CLOCK, DFF) onto a canvas, wire them, energize, watch signals propagate. Folded-in logic analyzer for sequential debugging.

12 gate primitives, testbench rows, propagation solver, folded logic analyzer.

Scroll the 6502 die from top-down overview through per-block reveal. Each week's lab lights up the block it touches. NAND-budget panel reads alongside the floorplan.

8 scrollytelling scenes, academy-original SVG floorplan, NAND-budget overlay.

Tick each week as your lab adds gates. Bar climbs from 0 toward the 3,500 NAND-equivalents the 6502 needs. Answers the Week-1 question every student asks: am I actually building a CPU?

Per-week checklist, running counter, LocalStorage autosave, badge embed mode.

2D board render with bitstream-load animation, 8 GPIO LEDs, 8 input buttons, USB-UART jack. Pick a demo bitstream, click Load, click Run, watch the LEDs count in binary.

5 demo bitstreams; memory-mapped IO at $D012 UART, $D013 LEDs, $D014 buttons.

4-pane workbench: source editor, compiled asm view, register + zero-page inspector, UART console. Hand-write 6502, watch the bytes appear, step through it, see the output land.

~50 mnemonics, 2-pass label resolver, 5 ready-to-load examples, UART at $D012.

Drop the 5 Lab 1.1 flashlight components into the 5 slots, energize, watch the LED light up. Probe the circuit with the 2-probe multimeter (voltage + resistance) and read node voltages a real $15 meter would show.

Click-to-place, per-slot target-match validation, voltage-trace mini-graph.

Per-lab entries, freehand sketch canvas, photo upload, multi-entry timeline. Export the whole journal as a PDF at the end of the week or the end of the course.

Markdown body, freehand canvas v1, IndexedDB autosave, export hooks.

Type Py6502v source, see it execute on CPython via Pyodide and on the emulated 6502 via py65, side by side. 5 golden examples bundled, all MATCH host vs target.

Pyodide host runner, py65 emulator, R5 compiler, 5 goldens MATCH.

Drop in NES CHR data, watch plane 0 and plane 1 combine into the four-color sprite the PPU draws. New: pick any sprite from the loaded ROM.

CHR table viewer, plane-by-plane animation, per-bitplane delta-color tinting, ROM sprite picker.

9 DSP block primitives, drag-to-wire SVG patches, live Web Audio runtime, FFT spectrum painter. Demo flow ships preloaded: source → throttle → filter → FFT plus parallel audio sink.

9 blocks, drag-drop canvas, live AudioContext, FFT non-zero pixel verification at runtime.

Rust/WASM L2-L4 parser, academy filter syntax, 36-entry curated library, wireshark.org direct-fetch browse (3,136 upstream captures), drag-drop upload with magic-byte sniff, five Driver.js tutorial walkthroughs.

Rust core, filter parser, tabbed picker, upstream index, tutorial engine.
