Lab and optics setups drawn as clean schematics, with the light or flow path in red.

Makes lab setup and optics diagrams as one finished PNG for a post, lesson, slide or poster: precise thin-line schematics with grey fills and one red path for light or flow, on a faint grid. The drawings come from a picture model and every word is set in real type on top, so labels are always spelled right. Best as one setup drawn left to right with labelled parts; other layouts work too. Needs a FAL_KEY or a Cloudflare Workers AI key; about $0.01 to $0.02 a drawing. Use when someone wants a diagram of an experiment, an optical bench or lab setup, or a schematic of how light or liquid moves through equipment.

About this skill

You say

Make a diagram of a simple distillation setup for my chemistry class

It said back

I've made the diagram: distillation/explainer.png (3200×1800, 16:9 slide format).

It's one labelled drawing of the setup, left to right: heat source → round-bottom flask → thermometer → condenser → distillate. A red line traces the vapour from the flask through the condenser into the collecting flask. I read every label in the final image; all are spelled correctly and none overlap. The footer says cooling water enters the condenser at the bottom and leaves at the top.
