https://digiwleea.wleeaf.dev/blog/ How digiwleea's browser circuit lab is built: the switch-level simulator, the editor, and the bugs along the way. en Thu, 16 Jul 2026 12:00:00 GMT https://digiwleea.wleeaf.dev/blog/ai-that-cannot-lie/ https://digiwleea.wleeaf.dev/blog/ai-that-cannot-lie/ Thu, 16 Jul 2026 12:00:00 GMT How digiwleea's AI tutor builds circuits users can trust: the model emits a logical netlist only, every layout candidate is verified against the real simulator (net-partition equality, not heuristics), measured truth tables feed back into the loop, and an honest no-build beats a plausible wrong one. https://digiwleea.wleeaf.dev/blog/paint-dont-rebuild/ https://digiwleea.wleeaf.dev/blog/paint-dont-rebuild/ Thu, 09 Jul 2026 12:00:00 GMT How a browser SVG circuit editor stays smooth: a strict paint-vs-redraw split, transform-only drags, and the insight that a state change (an input toggle) needs no DOM rebuild, a 2.6x speedup, plus keeping the cables clean with orthogonal drags, magnetic alignment, and loose-end detection. https://digiwleea.wleeaf.dev/blog/unbreakable-circuit-moves/ https://digiwleea.wleeaf.dev/blog/unbreakable-circuit-moves/ Thu, 09 Jul 2026 12:00:00 GMT Five distinct ways moving a component can silently break a schematic editor's connectivity, the fixes, and the seeded semantic-assertion harness that found them. https://digiwleea.wleeaf.dev/blog/how-the-simulator-works/ https://digiwleea.wleeaf.dev/blog/how-the-simulator-works/ Wed, 08 Jul 2026 12:00:00 GMT Building a browser switch-level logic simulator from scratch: transistors as switches, four-value nets, settling feedback loops into latches, and laying out wires so a circuit does not look like spaghetti.
