Experiments, from US$100 to a pilot line

Ten experiments in four budgets. Each one is drawn in 3-D: click a step and the parts it uses light up. Parts lists carry approximate 2026 prices, every step is spelled out, and the plot shows what a working setup should measure, simulated from the same models as the rest of the site.

Prices are approximate street prices for generic parts; check with vendors. Safety notes summarize hazards and never replace your institution's training. Markdown version: docs/experiments/EXPERIMENTS.md.
