High School Senior Project
An electromagnetic Thor hammer with fingerprint authentication.
Arduino-based control system and relay wiring
I implemented a powerful electromagnetic system using two heavy-duty door electromagnets. These electromagnets create a secure, high-force magnetic latch to metal surfaces when powered, simulating the hammer's signature immovability.
Fingerprint scanner authentication system in action
I integrated a fingerprint scanner with Arduino for secure access control. When the registered user's fingerprint is verified, the system cuts power to the electromagnets, allowing only the "worthy" user to lift the hammer.
Heavy-duty electromagnetic power supply assembly
I designed a robust power system utilizing four 12V lead-acid batteries wired in series to supply 48V. This high-voltage configuration provides enough current to the electromagnets to generate maximum holding force while remaining self-contained inside the hammer's head.
