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.
GSM-based Cellular IoT Home Automation
What if you are out of your home (and/or in another country) and suddenly realise that you have forgotten to turn off the geyser,...
Make Your Own FM Transmitter For Broadcasting
This FM transmitter design is one of the simplest you can build. No tuning is required, as the transmit frequency is crystal-locked at 90MHz....
Make A Battery-Operated Portable Temperature Measurement System
This project presents a K-type thermocouple-based temperature measurement system using MSP430G2553 microcontroller (MCU). The MCU reads sensor data and updates it on a four-digit,...
Convert 12V DC To 9V DC Using IC LM2576
You may already have on hand a 12V AC/DC adaptor or 12V from your PC or 12V battery, but you need a 9V, 2.5A...
