Today we're launching tinyohms.com — a virtual workbench where you can drag out a battery, a resistor, an LED, wire them up, and actually see the circuit run.
Why this exists
TinyOhms started with a parent on TinyClimbs. His son is obsessed with electronics — pulling apart toys, asking why the LED on one board is brighter than on another, wanting to build things but stuck between YouTube videos he doesn't fully understand and a component kit he's a bit afraid to short out. Dad asked whether we could put together something friendlier than a full-blown SPICE simulator, so a nine-year-old could actually poke at a circuit without setting anything on fire.
That's the whole product.
What's inside
The core is a browser breadboard. Drop parts on, connect them, hit run — voltages, currents and LED brightness update live as you wire and rewire. Nothing to install, nothing to buy, nothing to accidentally fry.
Around the breadboard sit small guided projects — the blinking LED, the voltage divider, the transistor switch — each one explaining the math behind the part, not just the recipe. The idea is that when the kid finally does pick up a real breadboard and a bag of components, they already know what should happen before they plug anything in.
Where it fits
It slots next to TinyClimbs the same way a printable maze sits next to a colouring book — a small tool for a curious kid, free to use, no login required to start. If TinyClimbs is paper-first, TinyOhms is wire-first.
Give it to a child in your life who won't stop asking how things work: tinyohms.com.
