UNDER- /OVER-VOLTAGE BEEP FOR MANUAL STABILISER

Manual stabilisers are still popular because of their simple construction, low cost, and high reliability due to the absence of any relays while covering a wide range of mains AC voltages...

WATCH MAN WATCHER

Here is a circuit that can be used in offices, stores, warehouses, etc during night to check whether the watchman of your establishment is on duty. For operation, it uses an...

MAINS SUPPLY FAILURE ALARM

When ever AC mains supply fails, this circuit alerts you by sounding an alarm. It also provides a backup light to help you find your way to the torch or the...

Sensitive Optical Burglar Alarm

This optical burglar alarm uses two 555 timer ICs. Both the ICs are wired as astable multivibrators. The first astable multivibrator built around IC1 produces low frequencies, while the second astable...

Emergency-Cum-Ultraviolet Light

This circuit serves both as an emergency light (using a 6W fluorescent tube) and an ultraviolet light (using a 6W ultraviolet tube). Step-down transformer X1, diodes D1 through D4, capacitor C1 and...

Clap-Operated Electronic Switch

Here’s a simple clap-operated electronic switch. Using this switch, you can turn on any appliance by clapping five times and turn it off by a single clap. The switch activates the...

LOW-COST ELECTRONIC QUIZ TABLE

Here is a simple, low-cost quiz table for four game participants. It determines the contestant who first presses the switch (S1 through S4) to answer a question and locks out the...

HIGHWAY ALERT SIGNAL LAMP

Here is a signal lamp for safe highway driving. The lamp automatically emits brilliant tricolour light when a vehicle approaches the rear side of your vehicle. It emits light for 30...

Low-Resistance Continuity Tester

Using this circuit you can check continuity of low-resistance paths such as PCB tracks, small coils, intermediate-frequency transformers (IFTs) and low-resistance transformers. However, you can’t check semiconductors with this tester. The...

Zener Diode Tester

This zener diode tester can be used to check zener diodes of 3.3V to 18V. The breakdown voltage of the unknown zener diode is indicated on the precalibrated dial of potmeter...
