Draw a schematic, simulate it with a solver I wrote from scratch, then take it all the way to a manufacturable board. Fully offline and vendor-neutral: the app opens no network connection at all and ships generic models instead of real vendor parts.

• MNA-based DC and transient solver, with Newton-Raphson for nonlinear devices — diodes, BJTs, MOSFETs, IGBTs, op-amps
• Virtual instruments: two-channel oscilloscope, signal generator, multimeters, frequency counter, logic probe
• Runs real RV32I (RISC-V) firmware inside the circuit — GPIO pins drive the analog side
• PCB layer stackup, 1:1 scale PDF printing, Gerber/Excellon manufacturing package, BOM CSV, SPICE netlist
• ERC and DRC engineering checks · 37 components across 13 categories · 17 test files guarding the engine

A metre-based floor plan editor for architects. Draw rooms and walls, drop doors and windows that cut real openings into the wall, stack floors, then flip the whole thing into isometric 3D with a section-cut view.

• Metre-based rooms and walls with live m² — overlapping rooms are resolved to net area, not double counted
• Wall-hosted openings: doors, sliding doors and windows cut a real gap, slide along the wall and travel with it
• Isometric 3D: walls extruded with lintels and sills, section-cut mode to see interiors, floors stacked
• 24+ architectural symbols across 6 categories, plus outdoor pieces — trees, cars, pools, street lamps
• Four themes including Blueprint · PDF, PNG and .archi export · millimetre snapping · multi-floor with ghosted level below
