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.
Control Four Appliances with a Touch Switch Panel
This project is based on a capacitive touch sensor for controlling four electrical appliances. Toggle switches have been used for operating lights or fans,...
HVDC Power Supply Design
Circuits like Geiger counters, insect zappers, Nixie tubes and sensors require high-voltage direct-current (HVDC) supplies. There are various types of HVDC power supply designs...
Protect Yourself With This Noise Level Monitor
Presented here is an Arduino-based noise/sound level monitor that displays sound levels in decibels (dB) and corresponding voltage levels on an LCD. A noise...
New Facial Recognition Smart Glasses For Visually Challenged Person
In this project, we will be making a prototype of a smart eyeglass that can help a visually challenged person to recognize the person...
Make This Simple Tester For Operational Amplifiers
This is a simple tester with square-wave oscillator for single and dual operational amplifiers (op-amps). These op-amps are widely used in different projects. You...

Hacking Bluetooth Headset To Control A Robot
In this project, an old Bluetooth headset can be used, along with a cellphone to make a robot controller, without a microcontroller (MCU) or...
Smart Receptionist With Smartlock System
Presented here is a security system that lets you see a visitor while your main office door is locked. If you are in...
Monitor Light Level In Underground Mines And Caves
This circuit monitors light in surrounding areas at all times, displays light level on the LCD and sounds an alarm when light level becomes...
Electronic Candle
Electronic or flameless candles are an alternative to traditional wick candles. These are used for home décor and do not carry the risk of...
Meter To Measure Short Distances
This Arduino-based distance meter can be used for measuring the distance between the sensor and object in the range of 2cm to 400cm using...
Wi-Fi & Bluetooth Mesh Enabled IOT Smart Device For Athletes
This device can provide real-time data of the movements of players during trainings and games, like acceleration, angle and directions, as well as their...
LED Torchlight
Most commercial torchlights use three AA or AAA cells connected in series, which produces 4.5V to drive white LEDs using a current-limiting resistor. These...
Dual-Colour Stroboscope
Stroboscope is a device used to make a cyclically moving object appear slow-moving or stationary. This is realised by illuminating the object intermittently with...
Make Your Own Joystick for Robot
Here is a simple joystick to control a robot to move in forward, backward, right, left, clockwise (CW) and counter-clockwise (CCW) directions using six...
Voltage Regulator as Audio Amplifier
LM338 voltage regulator can also be used as an audio amplifier. The output voltage can be controlled by varying the IC’s reference voltage (pin...
