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 …

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 …

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

Lantronix x Pico module is a highly flexible network connectivity solution for serial interface devices. Lantronix x Pico is 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 x Pico is that there is virtually no need to write a …
Currently revising the design to reduce weight and have bigger wing chord base on advise from DIY drones with slightly shorter wings. AUW 1521 Grams Wing loading 14.83 oz/ft² power to weight 270 Watts per Kg should perform much better than Yellow plane one. I’m changing from the D4023-850 Out Runner Motor to a higher kv TurnigyL3010C-1300kv Tests show significant improvement in static thrust …
In today’s wireless, connected world, ambient Radio Frequency (RF) energy is everywhere. Technically, this free-flowing energy can be captured, converted and stored for use in other applications. In fact, it is already in use in a number of ultra-low-power, battery-free applications, such as RFID tags, contactless smart cards, and wireless sensor networks. As a result …

“Sneaky, sneaky Apple,” said I Fix it’s chief information architect, Miroslav Djuric, in an e-mail announcing I Fix it’s teardown of 5th Gen iPod Touch 16 GB. “Thought you could pull a fast one on us by releasing a new, stripped-down version of the current iPod Touch without your customary fanfare? Not on our watch: …
Slewing behavior of op amps is often misunderstood. It’s a meaty topic so let’s sort it out. The input circuitry of an op amp circuit generally has a very small voltage between the inputs—ideally zero, right? But a sudden change in the input signal temporarily drives the feedback loop out of balance creating a differential …
From now, you´ll find in our store the top-quality capacitors from company AVX. A tantalum capacitor may be for many designers a component with a “smell of alchemy”. It´s not used as often as for example electrolytic capacitors, it´s more expensive and it doesn´t hesitate to fire off at improper handling. Despite these facts, it´s …
