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.

Touch Switch

Described here a touch switch circuit system that operates only when you touch two conductor terminals simultaneously with your fingertip.
