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.

Dual-Channel Active AC Analog Probe

Presented here is a low-cost, dual-channel, active AC analog probe. It is suitable for oscilloscopes, multimeters and other analogue measurement equipment. When experimenting with AM...
