1

Water Level Indicator: This Water Level Indicator project employs a simple mechanism which helps to detect and indicate the water level in an overhead tank or any other water container. It can be used in Hotels, Factories, Homes Apartments, Commercial Complexes, Drainage, etc.

2

Boolean Algebra Calculator: This Boolean algebra calculator is an interesting project which is more useful in our real life by working as a portable calculator to simplify the Boolean expression on the fly. In our circuit, we use Boolean algebra simplification methods like the Quine-McCluskey algorithm to simplify the Boolean expression and display the output on the display.

3

Unbiased Digital Dice with LEDs: This is a circuit diagram of digital dice which is nearly unbiased. By using this circuit, there is no chance to cheat as the circuit operates at such a high speed that the circuit is almost imperceptible to the human eye.

4

Automatic Washroom Light Switch: This is a simple but very useful circuit in our real life which helps to automatically turn On the lights when a person enters the washroom and it automatically turns Off the lights when he leaves it.

5

Intelligent Unambiguous Night Lamp Switcher: This is the circuit diagram of unambiguous night lamp switch, which turns ON our domestic lights automatically when it is dark, without human interference. It also avoids repeated frequent switching of the devices which is usually ignored in most similar circuits but may have a detrimental effect on our operating devices.

6

Automatic Door Bell With Object Detection: This automatic doorbell with object detection circuit helps to sense the presence of a person or an object automatically and rings the doorbell.

7

Panic Alarm: This panic alarm circuit helps us to intimate others regarding our bad situation without any delay. It is more useful when an intruder entering our house or bad health status at which we are unable to intimate to the people around us.

8

Continuity Tester with Melody: This circuit works as a continuity tester device which tests the continuity of the wire at hand. It is an indispensable tool to check broken wires and undesired shorting of wires.

9

Auto Night Lamp using High Power LED: This Auto Night Lamp is an interesting circuit which helps to turn ON the LED lights interfaced to it at night time and it turns OFF the lights automatically when it is day.

10

Thermistor Temperature Sensing Alarm: This circuit is a temperature sensing as well as alarm circuit. The circuit raises an alarm whenever the temperature crosses a certain limit.

11

Pull Pin Security Alarm System: This circuit helps us to get alerted when anybody picks our pockets or bags. The circuit is very helpful to prevent our goods getting pick pocketed.

12

Auto Turnoff Soldering Iron Circuit: This circuit helps the soldering iron to turn off automatically when it detects overheating and thereby avoids it from getting damaged.

13

Hot Water Geyser Controller Circuit: This circuit is made to turn OFF geysers as soon as our water gets hot and are ready for bathing.

14

Remote Operated Alarm Circuit: This circuit rings an alarm when you point a TV remote at it and press on any button. This can be used as a calling bell to call your assistant.

15

Fire Alarm with Siren Sound: This circuit alerts us when there is a fire accident at home by ringing a siren sound instead of a buzzer.

16

Automatic Railway Gate Controller with High Speed Alerting System: The main aim of this project is to operate and control the unmanned railway gate in the proper manner in order to avoid the accidents in the unmanned railway crossing.

17

Water Level Alarm Using 555 Timer: This is a simple and low cost hardware project using a 555 timer circuit. The aim of this project is to design a water level detecting alarm with simple and low cost hardware without compromising on the performance of the device.

18

Battery Powered Portable Light: This circuit is more helpful in handling unexpected and undesired darkness in our homes or offices. It provides considerable amount of brightness required to do our daily tasks.

19

Speed Control of DC Motor Using Pulse Width Modulation: This pulse width modulation technique is the more efficient way to proceed to manage the speed of our DC motor manually.

20

Interfacing 16x2 LCD with 8051: This is a simple circuit diagram which helps to describe interfacing of 16X2 LCD module to AT89C51which is a 8051 family microcontroller.

21

Car Parking Guard Circuit Using Infrared Sensor: This circuit helps the person in the driving seat in such a way that it gives an alarm if there is any obstacle or a wall while parking or while driving in reverse. It is very useful in our real life.

22

PWM LED Dimmer Using NE555: The Pulse Width Modulation (PWM) plays an important role in controlling the circuits. We use this PWM to dim the intensity of light of the LED.

23

Simple 100W Inverter Circuit: This is a small Inverter circuit which converts the direct current (DC) to alternating current (AC).

24

Lead Acid Battery Charger Circuit: Lead Battery is a rechargeable battery and is more useful in our real life as it will dissipate very little energy, it has very low energy to weight ratio, it can deliver high current, can work for long time with high efficiency and is very low cost.

25

Metal Detector Circuit: This is a simple metal detector circuit which is very useful for checking the person in shopping malls, hotels, cinema halls to ensure that person is not carrying any explosive metals or illegal things like guns, bombs etc.

26

Monostable Multivibrator Circuit Operation: Here is the monostable multivibrator circuit diagram and working. Multivibrator is an electronic circuit which will work as two stage amplifier operating in both stable and astable mode.

27

Interfacing16X2 LCD with PIC Microcontroller: This is a circuit which helps in interfacing 16×2 LCD to PIC18F4550 microcontroller which is of family PIC18F.

28

Battery Charger Circuit Using SCR: Here is the circuit diagram of battery charger circuit using Silicon Controlled Rectifier. SCR can be used in half wave rectifier, full wave rectifier, inverter circuits, power control circuits, etc.

29

Interfacing 16X2 LCD to AVR Microcontroller: This is a circuit which helps in interfacing 16X2 LCD with AVR Microcontroller. The Atmega16 belongs to the AVR microcontroller family.

30

FM Bugger Circuit: Here is small circuit with which you can listen to another people conversation from long distance using the normal FM radio set. This FM bugger circuit is kept in room where you want listen the conversation. You can listen to this conversation using the normal FM radio set.

Hi there this is somewhat of off topic but I was wondering if blogs
use WYSIWYG editors or if you have to manually code
with HTML. I'm starting a blog soon but have no coding
know-how so I wanted to get guidance from someone with experience.
Any help would be enormously appreciated!
