Introduction An audio amplifier increases the amplitude of a small signal to a useful level, all the while maintaining the smaller signal’s detail. This is known as linearity. The greater the amplifier linearity, the more the output signal is a true representation of the input. With the ever-changing performance requirements for amplifiers in the audio […]

What’s UDOO? UDOO is a mini PC that could run either Android or Linux, with an Arduino-compatible board embedded. UDOO is a powerful prototyping board for software development and design, it’s easy to use and with a few steps you can start using it and creating your projects with minimum knowledge. UDOO merges different computing […]

The culprit is UV radiation, which is outside the range of visible light but still can affect photographic images by lowering their overall contrast. Don’t despair. You can overcome the problem by using a UV filter. By reducing the amount of UV light, you can capture a photographic image that more closely resembles the image […]

−Inhaltsverzeichnis flux probe theory of operation circuit explanation Fotos Notes flux probe FluxProbe is a test prod for measuring currents without touching the conductor it is flowing through. More acurately it is measuring the magnetic flux. This way you can measure currents on PCB traces without having to put a resistor in between. This test […]

Bluetooth devices communicate wirelessly with each other through short-range radio waves that have a maximum reach of about 10 meters generally, or 30 feet, although some more high-powered devices have longer ranges. Unlike devices that require a direct line of sight like remote controls, Bluetooth-enabled products just need to be in the same area in […]

Lantronix xPico module is a highly flexible network connectivity solution for serial interface devices. Lantronix xPicois thanks to its miniature dimensions (smaller than a usual SD card) suitable even for designs typically intended for chip solutions. The key difference with the xPico is that there is virtually no need to write a single line of […]

First and foremost, the Xperia Play is a phone. It runs on the Android operating system and supports apps like any other smartphone. The phone went on sale May 26, 2011 in the United States with a $200 price point and a standard two-year Verizon contract. The Play supports 3G Internet connectivity like every modern […]

Easy Pulse is a DIY pulse sensor that can be used for detecting the cardio-vascular pulse wave from a fingertip. It is designed for hobby and educational applications to illustrate the principle of photoplethysmography (PPG), which is a non-invasive optical technique of retrieving vital information about the cardiovascular system from the skin surface. It uses […]

This mix of fun, public service, friendship and convenience is the main feature of amateur radio. The true origin of the term “ham” seems to have been lost, but there are several theories. It may simply be a shortcut way of saying the first syllable of amateur radio, or it may have originally been used […]

Function generator with adjustable frequency from 0 Hz to over 400 kHz, adjustable amplitude, DC offset, duty, and of course the function selection – square, triangle, and sine. Generator based on good old ICL8038 integrated chip generator that gives pretty good shaped signals as for amateur purposes. This circuit has been designed a little differently […]
