FiDUS Power is pleased to announce the addition of the exciting convection cooled, high efficiency, SUF350 AC-DC open frame power supply. With the SUF350, system designers can utilize 250W of output power from the dense 3 x 5” package without the need for fan cooling. Where fan cooling is acceptable, the full 350W potential of the SUF350 can […]

FiDUS Power, the technical power supply distributor specializing in innovative solutions and new products that benefit system designers as they seek to differentiate their end products, sets a new bar for the size of external power supplies with the launch of the new model GDA200. The use of Gallium Nitride (GaN) rather than silicon semi-conductor
This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Creating emergent patterns that can be converted into sounds fascinates me. So this is my first experiment in building an arduino platform for creating such patterns. This version uses a Gameduino as its

DAC is short for Digital to Analog Converter. In this article we play around the code Michael Smith created for a PWM based DAC. I modified his code so that other DAC options could be tried. I compare the 8-Bit PWM DAC with the R2R DAC at various numbers of bits. You might be surprised

The Raspberry Pi, although first intended as an inexpensive single-board computer for use in education, is now ubiquitous in electronics communities. Its low price as well as Linux platform and accessible GPIO make it useful in many places outside the classroom. But, if you want to abandon the ease-of-use in favor of an even lower

Toradex leverages Amazon® Web Services (AWS) and NXP® to demonstrate how to simplify the creation of Industry 4.0-ready industrial automation solutions. A live demonstration that leverages expertise and technology across all three companies will be on display at the Industry of Things World in Berlin from September 16 through September 17. The demo includes: The demo is built around a

This is add-on of the audio amplifier project result which is introduced in other instructable. (https://www.instructables.com/PC-Speaker-Amplifier/) Usually many types of sound level meters are directly connected with input (or rarely output) signal lines of amplifier. But personally I’m thinking any electrical connections with amplifier circuit may surely degrade music playback quality by inserting some noises

Flashing LEDs are all well and good, but they’re even better if they can sync up with ambient sounds or music. [mircemk] has built the LUMAZOID visualizer to do just that, relying on some staple maker components to do so. The build is open-source, and designed to work with strings of 60, 120, or 180 WS2812B

You don’t have two ears by accident. [Stoppi] has a great post about this, along with a video you can see below. (The text is in German, but that’s what translation is for.) The point to having two ears is that you receive audio information from slightly different angles and distances in each ear and your

We all love seeing data represented in pretty ways — whether it’s necessary or not. Take VU meters for example. They’re a super useful tool for audio editors to balance signals, but they also look really cool, even if you’re only listening to music. Who didn’t use a Winamp skin with a built-in VU meter back in
