Hey Product Hunt — Paul here 👋 I built CircuitDiagramMaker because an electrical drawing is only the beginning of the job. The same components and connections often have to be recreated across a schematic, prototype, panel layout, cable schedule, bill of materials and final handoff. Every duplicate introduces drift. CircuitDiagramMaker keeps that work in one structured browser project: • Draw schematics and wiring with automatic routing and net tracking • Carry the same design into breadboard, PCB Lite, and 2D/3D control-panel views • Generate live device, wire, cable, terminal, load, PLC I/O and BOM reports • Run supported DC, transient, AC, and control-circuit simulations • Review changes, preserve releases, and export PNG, SVG, PDF, DXF, SPICE and CSV • Start as a guest with local recovery—no account or installation required The library currently includes 482 electrical symbols and 2,278 editable diagram references. Every new account receives a 14-day Pro trial without a card, then returns to Free unless the user explicitly subscribes. I have tried to be equally clear about the boundaries: this is not a claim to replace native DWG workflows, plant-scale catalogues, production PCB DFM, arbitrary SPICE models, or professional engineering sign-off. It is built for accessible, connected electrical documentation and handoff. I would especially value feedback from electrical designers, controls engineers, technicians, makers and educators: 1. Where does your handoff break today? 2. Which physical workspace or report should we deepen next? 3. Which symbol or starter template is still missing? Thanks for taking a look. I’ll be here throughout launch day and will reply to every question.
