A popular tool in chiptune software like LSDJ allows the user to draw a waveform and use it as the basis for a wavetable synth. It’s fun and it can produce some great bleeps and bloops. [Kevin] has created a similar tool using an Arduino and a touchscreen. The build is based on the Arduino Uno, […]

It’s a distressing moment for some of us, when a formerly prized piece of electronic equipment reaches a point of obsolescence that we consider jettisoning it. [Jon Robinson] ran into this dilemma by finding the Kenwood Hi-Fi amplifier his 17-year-old self had spent his savings on. It was a very good amp back in the

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

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

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

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
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
NEW SUF350 – FAN-LESS 250W IN ONLY 3 X 5” AND UP TO 95% EFFICIENT Continue Reading
Diamond Systems has unveiled a Stevie carrier board for Nvidia’s high-end Jetson AGX Xavier module. Diamond also promoted some other Jetson carriers and embedded systems, which all ship with Linux BSPs. They include Diamond Systems’ Elton, also for the Xavier, the Jethro and Ziggy carriers, both of which support the earlier Jetson TX2 and industrial-temperature Jetson TX2i. Diamond also included the Ziggy-based ZiggyBox mini-PC and its Jetbox-Nano enclosure for Nvidia’s Jetson Nano Development Kit for the Jetson Nano module. At 105 x 92mm, the Stevie board

People love listening to music. It is as they say, music reflects our mood. And it is a spectacle to see music become ‘alive’ right before our eyes. Well, that’s what music visualization does. According to Wikipedia, music visualization “generates animated imagery based on a piece of music. The imagery is generated and rendered in
