Tools for people who build their own.
Practical tools for people who build things by hand: a van that has to carry its own water and power, a 12 V system that must not catch fire, a nutrient tank that has to grow food. Each one turns a pile of measurements into a plan you can buy parts from.
Modular 80/20 aluminium furniture for a van: beds, island, kitchen and a tilting solar roof rack, sized from your van's own measurements.
How Van-Ish works → 12 V electrical · playableA circuit bench for van power. Wire batteries, solar, chargers and loads on screen and watch every volt, amp and fuse behave as it would.
How Van Power Lab works → Hydroponics · liveA nutrient formula solver for hydroponic growers. Set a target, pick the salts you have, and get gram weights and an A/B mixing guide.
Use it free · download → Grow library · liveAsk a shelf of cultivation and hydroponics books a question and get an answer that cites the book it came from. Reviews a NuTruCalc recipe in one click.
Ask a question →Every dimension, rating and price is a setting you can change. Estimates are marked as estimates until you replace them with a measurement.
Each tool tells you what would fail: a bed that hits the wheel well, a wire that overheats, two salts that turn to sludge in the same tank.
The output is something you act on: a cut list and parts list, a wire and fuse list, a gram-by-gram recipe.
