UPDATE: Think That USB Port’s Just for Charging? Think Again.
Low battery. No outlet. That public USB port looks like a lifeline—but it could be a hacker’s keyboard in disguise. Enter choicejacking—a next-generation cyberattack that hijacks our phone without permission. No taps. No clues. Just stolen access. If we care about our data, we must not plug in until we know what that charger is really doing.

PROJECT: Laptop-Based HMI For DC Motor Speed And Direction Control
DC motors are usually controlled with switches or buttons for direction and a potentiometer for speed. While the potentiometer remains effective for speed regulation, this system offers an alternative, enabling both speed and direction control of a DC motor (up to 36V) directly through a laptop.

PROJECT: An IoT Gas And Environment Monitor Sensor
Environmental sensing plays a key role in managing air quality, controlling pollution, ensuring factory safety, detecting hazardous gases, and supporting laboratory monitoring. To be effective, such systems must be battery-efficient, lightweight, compact, versatile, and capable of real-time wireless data transmission. While most existing solutions are bulky, this design offers the same functions in a compact multi-gas sensor module. | | |

PROJECT: Water Level And Temperature Monitor With TFT Graphics Using Arduino
Water and temperature monitoring systems are crucial across various industries, including the chemical, pharmaceutical, and textile sectors. They help maintain precise liquid levels and stable temperatures—factors essential to ensuring product quality. In chemical processing, for instance, both parameters must remain within defined limits throughout the operation.

PROJECT: Pi Zero World Wide Web Streaming On Mobile Hotspot
Webcasting on a server-grade machine such as a laptop or desktop is routine and unremarkable. Streaming through modem port forwarding is similarly straightforward. What is far more challenging, however, is achieving stable, long-term webcasting using only a mobile phone as a Wi-Fi hotspot and a compact Raspberry Pi Zero instead of a full-sized computer. This was accomplished with a Raspberry Pi Zero equipped with just 500MB RAM and a 5MP Pi Zero camera—small in form, yet powerful in function. | | |

PROJECT: A Small Touch-Controlled Solid State Relay
The demand for modern touch-based control systems is rising quickly, driven by their sleek design, ease of use, and lack of mechanical components. This system introduces an AC touch-controlled solid-state relay (SSR) capable of handling input voltages from 100V to 250V AC. It is designed to switch loads such as bulbs, fans, and other household appliances. At its core is the TTP223 touch sensor IC, which integrates an ADC converter and supports selectable touch modes via a solder jumper (J1).
