DIY build projects
Low-voltage builds for learning by doing.
Starter projects are scoped for breadboards, modules, batteries, and supervised workshop practice.
Safety first, always.
ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.
