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.
5 Awesome Arduino DIY Projects From The Internet
Looking for a brilliant DIY project idea for your Arduino? For the crafty geeks out there, here we bring 5 inspirations you can choose...
Solder Fumes Remover
During soldering, lead fumes are generated, which are toxic. The flux used for soldering also emits fumes, which again are highly toxic if inhaled...
Fan on/off Control by Light
This circuit lets you turn on/off a fan by just directing torchlight or other light toward its light-dependent resistor (LDR). The circuit is powered...
Seven-Colour LED Lighting
Presented here is a simple circuit that uses six red, green and blue (RGB) LEDs to generate a running-light effect in seven colours—blue, green,...
ELECTRONIC MOTOR STARTER
This motor starter protects single phase motors against voltage fluctuations and overloading. Its salient feature is a soft on/off electronic switch for easy operation.
The...
Electronic Door Lock
Home burglary incidents are on the rise. Homes without proper security measures in place are particularly more vulnerable. But, it is easy to avoid...
RPM Meter for Automobiles
An efficient way to measure the RPM of a vehicle is through its ignition pulses. RPM of a vehicle is directly proportional to the...
Wi-Fi Embedded Webcam
This project is built around an MRF24WBOMA Wi-Fi module, a PIC microcontroller and a camera module using the TCP-IP protocol. The camera captures live...
Temperature Monitor for Electronic Equipment
As most electronics components’ characteristics vary with temperature, they are selected as per expected operating temperature range of the equipment. So it is important...
Efficient LED Blinking for Embedded Systems
Smart hardware design can simplify the embedded software and make it more reliable. Designers use blinking LED signals to indicate different status and for...
SCR-Controlled EHT Power Supply
Presented here is an extra-high-tension (EHT) power supply capable of delivering variable DC voltage from about 100 V to 5 kV with load current...
Transistor Polarity Checker
Presented here is a simple circuit that will help you figure out whether a transistor is npn or pnp type. If the transistor under...
Demo Circuit for Over-Voltage Protection
Over-voltage protection circuits are used to protect voltage-sensitive loads. Voltage transients may occur due to a number of reasons such as transformer switching, load...
Propeller Message Display with Temperature Indicator
Here we describe a microcontroller-based propeller display that displays any message sent to it via hyper-terminal of a personal computer. Moreover, a temperature sensing...
Dual Motor Control for Robots
Presented here is a simple circuit that can drive two motors for a small robot, allowing the robot to negotiate an obstacle course. Two...
Stereo audio Distribution Buffer for headphones
Most audio signal sources have only one stereo output, which means they can drive only a single pair of headphones with a resistance of...
Wireless PA for Classrooms
In large classrooms, many a times the teacher’s voice is not audible to students in the back rows. So the teacher have to literally...
Stop Clock With Battery Backup
Stop clock is widely used in various fields to measure the timing of events. Science laboratory experiments, such as measurement of discharge rate of...
