## What is Wattsmith?

Wattsmith teaches you to build your own electricity from the ground up — literally. Start with an earth battery made from soil, then move up to solar, wind, micro-hydro, hand-crank, thermoelectric, and more. Every build is broken into reusable modules (source, regulator, storage, output) so what you learn on one project carries to the next.

What makes Wattsmith different is honesty. Every project shows its real power output, energy per day, build cost, and what it can actually run — no hype. The earth battery lights an LED; solar genuinely charges a phone; micro-hydro quietly beats everything by never stopping. You'll always know what you're getting before you build.

INCLUDED FREE
• Earth Battery, Solar Panel, Hand Crank, and Saltwater builds
• Full parts lists with buying links, a shopping list, and an inventory tracker
• A Learn library: electricity basics, components, improvising parts, soldering, and tools
• Power Rankings comparing every source, and achievements as you build
• Works completely offline — no signal, no account, no tracking

WATTSMITH PRO — one-time purchase, no subscription
• Advanced builds: Wind Turbine, Micro-hydro Water Turbine, and the Solar Tracker upgrade
• The Power Calculator — turn the honest ranges into your own numbers
• A private, on-device AI assistant to help you build, troubleshoot, and stay safe

Every build keeps the scale small and safe. Wattsmith is for learning, tinkering, and emergency preparedness — a real science lab in your pocket.
