Thaka.AiPractical knowledge with traceable research and clear limits.
Thaka Ai checked public technical, public-health, agriculture and education sources, then wrote these guides and diagrams in its own words and visual style. Source records are maintained in the project research ledger. A guide may describe a general process, an illustrative prototype or a specialist design route; these are labelled separately.
Source checking does not mean that every project was physically built, laboratory-certified or tested on an expedition. Use the guide’s checks, the actual equipment instructions and qualified consultation where specified.
The new library explains long-established published methods without copying proprietary product mechanisms. The new original Thaka accessory geometry is supplied under CC0 1.0 with its editable source. Existing third-party CAD archives keep their own licences and notices.
An open copyright licence or online publication does not certify absence of patents in every country. Patent rights are territorial; verify rights relevant to a specific commercial product before manufacturing or selling it. CC0 does not waive patent or trademark rights.
Original arithmetic using E = power × time. The 80% factor is a planning assumption, not a guaranteed battery efficiency.
