Magic Smoke

Built for a laptop. The 3D board needs a mouse or trackpad to build circuits; on a touch screen you can look around it, but not wire it.

How this works

Read the brief. It sits along the bottom of the board, with what to do as a list. The arrows by its title step to the next challenge and back; the title opens the full list, and the arrow in its corner tucks it away when you want the room.
Build on the board. It is 3D. In Edit, Select drags parts and wire ends, Wire joins two holes, and Flip turns a part round; in Look you walk round it. Right-drag orbits in either, and the scroll wheel zooms.
Run to try it — the board goes live — then Submit to be graded. Letting the smoke out costs nothing here.
