Hey Product Hunt 👋 I built EasyCircuit because of a much weirder project: an instrumented orchid growth chamber. I wanted to run real causal-inference experiments on plant growth — controlled interventions on temperature, humidity, light — which meant I needed a custom sensor/actuator circuit with an ESP32, humidity sensors, a pump, heaters, LEDs, all wired together correctly. I know how to write code. I did not know how to design a circuit. Every time I tried, I'd hit the same wall: which pins are safe to use, what resistor values won't fry a sensor, whether a part I liked online was actually in stock anywhere. Days would disappear into datasheets before I'd wired a single connection. So I built the tool I wished existed: describe what you want in plain English, and a copilot designs the full schematic, lays it out for a breadboard so you can prototype before anything is soldered, and matches every part to a real, in-stock supplier — then bundles it into one made-to-order kit if you want it shipped. It's still early — 290+ parts in the catalog today, more added weekly — and it's meant for exactly the person I was a few months ago: comfortable with code, new to electronics, tired of losing a weekend to a part that turned out to be discontinued. Would love your feedback, especially if you try describing something weird and see what it designs. That's the best way to find where it breaks.
