Everything here is made in a tab.
No account, no upload, no waiting for a build to compile in the cloud. Every artifact in the maker studio — a circuit, a trained policy — is small enough to fold into a link. Open one, change it, share your own. This is the shelf.
Four loops worth stealing.
Each opens live in the circuit lab with the exact battery, resistor, and LED already placed. Change one value and watch the multimeter — that is the whole lesson of a current-limiting resistor.
The safe blink
9 V through 470 Ω into a red LED — ~14.9 mA, lit and living. The textbook current-limited LED.
Remix this circuit →Too much current
Same battery, same LED, but only 47 Ω — ~149 mA. Watch the verdict flip to BURNING OUT. Undersize the resistor and you cook the part.
Remix this circuit →A dim glow
Drop to a 3 V coin cell — only ~2 mA gets through. Lit, but barely. Voltage headroom is why the blink is faint.
Remix this circuit →Gated by a press
A button in series — the LED is dark until you press it closed. The first thing a sensor ever does: complete a loop.
Remix this circuit →The benches behind the shelf.
Everything featured here came out of one of these. Each runs entirely on your device.
The circuit lab
Battery, resistor, LED, button — solved live by nodal analysis. Light it without the smoke.
Open →The four verbs
Sense, think, act, imagine — each a live lab where a policy learns in the browser. Train one, then drive it.
Open →The Maker Studio
Design a part on a real CAD kernel, flash a board over USB-C, hand an STL to your slicer.
