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.
Cellphone Operated Land Rover
Conventionally, wireless-controlled robots use RF circuits,which have the drawbacks of limited working range, limited frequency range and limited control. Use of a mobile phone...
Pressure Sensors on Railway Tracks
Every year thousands of animals die after being hit by trains. Animals on train tracks are dangerous for both animals and the train as...
Simple Event Counter
Microcontroller based miniscule event counter presented here is based on the inexpensive Digispark Attiny development board. One advantage of this design is that any...
FM Booster
An antenna amplifier boosts a radio signal considerably for devices that receive radio waves. Many devices have an RF amplifier stage in their circuitry, that...
Door Guard
This door guard uses operational amplifier µA741 and a light-dependent resistor (LDR). Operational amplifier µA741 is used as a sensitive voltage comparator. Preset VR1...
Electronic Bicycle Lock
The electronic bicycle lock described here is a worthwhile alternative for bicycle owners who want to make their bicycles 'intelligent' at reasonable cost. One...
Electronic Watch Dog
Here’s an electronic watch dog for your house that sounds to inform you that somebody is at the gate. The circuit comprises a transmitter...
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...
IoT Based Notification System Using Android App
Presented here is a smart notification system for a door sensor, motion detector, fire alarm and doorbell using Raspberry Pi (RPi) and Pushover app....
Electrolysis-Free Water Level Alarm
In most water level monitors and alarms, corrosion of the probes makes the systems unusable in a few months. This water level alarm uses...
Top 20 RFID Project Ideas
Radio-Frequency Identification (RFID) is a technology that uses radio-frequency electromagnetic fields to transfer information from a tag to RFID reader for identification purposes. The...
Laser Communication System
This laser communication system transmits sound or music signals through a laser beam. The intensity of the laser beam changes with the amplitude of...
DC-AC SSR Switch for Microcontroller/Robotic Projects
SSR stands for Solid State Relay. SSRs are not very different in operation from traditional electromagnetic relays that have movable contacts. An electromagnetic relay...
Arduino-based Line Frequency Meter Based on Reciprocal Counting
Precise measurement of line signal frequency is very important in many applications, especially in the management of power grid systems. Tasks like calibration of...
Surveillance Camera Using RaspiCam And Android App
This project describes how to build a surveillance camera based on Raspberry Pi (Raspi) that records HD video only when something moves in the...
Mini Candle Light Using Old Mobile Phone Battery
According to the three Rs—reuse, reduce and recycle—we must save our planet from e-waste. Sometimes we have a dead mobile phone whose battery is...
Configurable DC-to-DC Converter Module Using Three ICs
Most kits with embedded microcontrollers (MCUs) operate off a single power supply (VCC) source like 5V or 3.3V. But for some experiments you need...
Make Your Controllers For Any Game Using Arduino: DIY
Nowadays, we have lots of game controllers that are improving the gaming experience over the years. There are number of factors responsible for a game...
