The Professor

Channel publishes hands-on DIY projects that repurpose motors, transformers and used batteries into homemade power systems and tools. Recurring topics include building and rebuilding batteries (LiFePO4 and laptop cells), making generators and motor-based power sources, DIY motor controllers and regenerative/braking power setups, and high‑temperature metal‑melting devices like plasma or arc furnaces. Videos emphasize practical reuse of discarded electronics and step‑by‑step build demonstrations.
