8051 Microcontroller based electronic locker system CIRCUIT DESCRIPTION Security is a prime concern in our day-today life. Everyone wants to be as much secure as possible.The issue of security is very paramount at home doors and safe. An access control for doors formsvital.link in a security chain. Therefore we intend to aid in security at home […]

New series of Sunon fans with IP68 protection brings reliability even to conditions, where a usual fan doesn´t withstand too long…Still more noise and vibrations and in extreme case even a total malfunction – this is a typical “end” of the fan after a long-time operation in a dusty or corrosive environment. In a usual […]

At the same time you can be sure of a set temperature and a long-term stability that´s why it´s suitable even for the most demanding usage. Production of company Weller (member of Apex Hand Tools) represent a synonym for top quality soldering stations intended even for a continuous 24h usage. In the Weller portfolio can […]

There have been numerous cases of lithium-ion batteries catching fire in everything from mobile phones and laptops to cars and airplanes. While the odds of this occurring are low, the fact that hundreds of millions of lithium-ion batteries are produced and sold every year means the risk is still very real. Researchers at Stanford University […]

This is 5V portable power supply circuit for pic microcontroller experiments. or PIC microcontroller power supply circuit. As The PIC16F627A microcontroller use 5 volts DC power supply. My son need to build it as 5V portable power supply circuit, because of the need for safe and convenient use in all locations. How it works I […]

Shown here is a prototype laptop power adapter made by Cambridge Electronics using GaN transistors. At 1.5 cubic inches, this is the smallest laptop power adapter ever made. Credit: Cambridge Electronics An exotic material called gallium nitride (GaN) is poised to become the next semiconductor for power electronics, enabling much higher efficiency than silicon.In 2013, […]

Project description F*watch is a fully open electronic watch project featuring an integrated GPS receiver. The development started at CERN as an after-work project to make a special present for a retiring colleague who likes hiking and timing. The full design (electronics, mechanics and software) is available under free licenses and the design is exclusively […]

The Toshiba TCM5115CL is the latest addition to its sensor line-up for digital still cameras which offers high image quality using backside illumination technology (BSI) to improve sensitivity and imaging performance. The TCM5115CL is a 1/2.3-inch CMOS image sensor with an imaging pixel array of 5216 (H) × 3920 (V). Use of the CMOS process […]

The PIC16F887 is one of the latest products from Microchip. It features all the components which modern microcontrollers normally have. For its low price, wide range of application, high quality and easy availability, it is an ideal solution in applications such as: the control of different processes in industry, machine control devices, measurement of different […]

Capacitors are vital components in electronics, but sometimes they are broken, or the value printed on the cap has become unreadable. Because my multi-meter does not have a capacitance measurement, I decided to make one!The principle of measuring capacitance is quite simple. The voltage of a capacitor charging through a resistor increases with time T. […]
