HDD Selector Switch

Using the switch-mode power supply (SMPS) of your personal computer, this add-on circuit lets you switch between three hard disk drives (HDDs) and also ensure that nobody else can open your...

Timer for Mosquito Destroyer

In electric-heating mosquito repellents, an electric vaporiser heats up a mat or liquid to release non-degrading chemicals into the air and keep the mosquitoes away from the closed surroundings. Here's a Mosquito...

Pushbutton Control For Single-Phase Appliances

This circuit lets you switch off and switch on a single-phase appliance using two separate push switches. Such an arrangement is common for industrial motors (mostly 3-phase) where an isolation is...

Doorbell-controlled Security Switch

One way to check whether anybody is at home is to ring the doorbell. Burglars too use this very technique. The circuit described here comes handy in such a situation. It...

ELECTRONIC CANDLES

Here is a simple circuit that can produce the effect of candle light in a normal electric bulb. A candle light, as we all know, resembles a randomly flickering light. So,...

TELEPHONE CALL RECORDER

Today telephone has become an integral part of our lives. It is the most widely used communication device in the world. Owing to its immense popularity and widespread use, there arises...

Smart Loop Burglar Alarm

Simple loop burglar alarms sound whenever the loop breaks. What if a clever thief comes to know of the working of this alarm? He may simply short the loop by using...

CAR-REVERSING HORN WITH FLASHER

Here is a simple circuit that starts playing the car horn whenever your car is in reverse gear. The circuit (refer Fig. 1) employs dual timer NE556 to generate the sound....

Stereo Headphone Amplifier

Here is an inexpensive circuit for a stereo amplifier to drive a low-impedance headphone set. The circuit uses a few cheap transistors (BC547 and BC557) and passive components like resistors, diodes...

Whisker for Robots

Whiskers for robots are simple switch-type sensors that work like an animal’s whiskers detecting nearby objects in the environment. When disturbed, the sensor sends a pulse to the robot to indicate...
