Clap On Clap Off Switch
This project aims to create a "Clap On Clap Off" switch circuit for home automation using a condenser microphone, 555 timer IC, D-flip flop, LED, and other basic electronic components. The circuit works by using the microphone to detect clapping sounds and convert them to electrical signals that trigger the 555 timer, acting as a clock pulse for the D-flip flop. This allows the LED to be turned on with the first clap and off with the second clap, functioning as a switch controlled by hand clapping. The total cost of components for the circuit was estimated to be around 247 Taka.

AUTOMATIC LIGHT & DARK SENSING SYSTEM WITH MOSQUITO REPELLENT CIRCUIT
DESCRIPTION
It is a simple and powerful concept, which uses transistor (BC 547) as a switch to switch ON and OFF the light automatically & a Light Dependent Resistors (LDR) which senses the light, made from a piece of exposed semiconductor material i.e cadmium sulphide, that changes its electrical resistance from several thousand Ohms in the dark to only a few hundred Ohms, when light hits the device, the photons give electrons energy by creating hole-electron pairs in the material. This makes them jump into the conductive band and thereby conduct electricity.
The circuit automatically switches ON lights when the light goes below the visible region & automatically switches OFF lights when light fall on it, by using a sensor which senses the light just like our eyes.
Also, the circuit has a long response time requiring many seconds to respond to a change in the light intensity.

Amplifiers Pesentation
An amplifier takes a weak audio signal and boosts it to a stronger signal that can drive a speaker. It does this through a process of multiple boosting stages within the amplifier. At the heart of most amplifiers is a transistor, which uses variations in its electrical resistance controlled by a small input signal to modify a larger output current supplied by the amplifier's power source. This allows it to accurately reproduce the original audio signal but at a higher volume level suitable for the speaker.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Clap switch
- 2. Clap switch means…!! Clap switch is switch which can switch on/off any electrical circuit by the sound of the clap
- 3. Principle…. Converts the sound signal into electrical energy
- 4. Basic Idea on clap switch is Basic idea on clap switch is that the electric microphone pick up the sound of your claps, coughs, or any sound to switch ON/OFF the circuit
- 5. Components are.. 1.Resistors 2.capacitors 3.Battery 4.Transistor 5.Relay
- 8. Working Audio amplifier Sound signal is received by AUDIO AMPLIFIER . Here the given sound signal is converted into electrical signal and then amplified by using transistors.
- 9. Flip flop circuit It consists of two transistors, one for the on position and the other for the off position. For this reason it is also known as bi-stable multi vibrator.
- 10. Circuit amplifier The outcome of this circuit is Electrical signal. This electrical signal is very weak so we have use another transistor in this circuit.
- 11. ADVANTAGES 1. The primary application involves an elderly or mobility-impaired person. 2. We can turn something (e.g. a lamp) on and off from any location in the room (e.g. while lying in the bed) simply by clapping our hands. 3. Low cost and reliable circuit. 4. Complete elimination of man power. 5. Energy efficient.
- 12. DISADVATAGES 1. It is generally cumbersome to have to clap one’s hands to turn something on or off and it is greatly seen as simpler for most use cases to use a traditional light switch. 2. Unless we use a filter in the circuit , it is not that advantageous. So that circuit activates only for clap of particular frequencies and then it becomes accurate.
