MEGA COLLECTION OF ELECTRONICS DIY PROJECTS

Every week, we publish 2 to 3 projects, sometimes even more! They range from simple circuits for beginners, to advanced projects that you can use to develop complete innovative products! Most projects have been developed by enthusiasts like you. Some by experts. And, some by our team. Many are tested at EFY Labs, and some are not–but they typically have a proof-of-concept video.

BioVision Lock-your object becomes the“Visual Key”

BioVision Lock is an intelligent security system that introduces a two-stage authentication mechanism by combining AI-based object detection with fingerprint recognition. The system uses...
