Blockless — say your idea, build a real gadget
Blockless turns a plain-English idea into a working hardware build. Describe what you
want — "a desk gadget that shows temperature on an OLED" — and it picks real,
plug-together modules (Raspberry Pi Pico W, ESP32 boards, sensors, displays), wires
them in an interactive 3D view with real pin labels, writes the MicroPython firmware,
and runs the whole thing in a browser-based simulator. No soldering, no toolchain
setup, no electronics background needed.
How it works
The simulator runs MicroPython compiled to WebAssembly, so the code running in your
browser is the code you would flash to the real board. Every build in the public
gallery is a live artifact: open a link and the same simulation runs for you.
