Raspberry Pi Used to Build Beautiful Music Table

Redditor Dtphantom used a Raspberry Pi to build this awesome “music table” that is reminiscent vintage stereo consoles.

Back before smartphones, video games, and even TVs, families would gather around the stereo to listen to music and radio dramas. Stereos from that era were often built into large pieces of furniture, called consoles. They would usually be the centerpiece of a room, in the same way that we mount our TVs as the focal point of living rooms today. Stereo consoles are rare now, since music players and speakers have become miniaturized. But some people still like to focus on the music, which is why Redditor Dtphantom used a Raspberry Pi to build this awesome “music table” that is reminiscent of those vintage stereo consoles.

DIY SDR DSP Radio with Raspberry Pi and RTLSDR Dongle

The radio presented above is capable of receiving the entire spectrum, from 500 kHz to 2 Gigahertz.

Software-defined radio (SDR) is a radio communication system where components that have been traditionally implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system.

Boochow’s RaspberryPi Pico Receives and Decodes MIDI Signals via Its USB Port

Developed using the TinyUSB library, this project receives MIDI messages via USB and decodes them for printing via UART.

Pseudonymous developer “boochow” has used the popular Raspberry Pi Pico in the heart of a MIDI device with a difference: Rather than making music, it’s designed to monitor and display the MIDI signals received from a USB MIDI device.

Mictic’s Wearable IMUs Turn Your Movements, Gestures Into Music via Smartphone App or MIDI

Prototyped on mbientLab Bluetooth IMU technology, the Mictic wristbands look to turn making music into simply moving your arms.

Zurich-based Mictic is looking to change the way people create and interact with music, using a wearable wristband-like instrument dubbed the Mictic and designed to translate gestures and movements into sound in real-time.

“Mictic is the Swiss-made XR [cross reality] wearable that turns your movements into sound,” Mershad Javan says of his company’s product. “It doesn’t matter if you already have a Grammy or have never picked up a musical instrument, with Mictic you’ll be expressing yourself the minute you put the wristbands on and connect via Bluetooth.”

A Hi-Fi Speaker From Some Foil and Magnets

In the world of speakers, mass is the enemy of high frequency response. In order to get the crispest highs, some audiophiles swear by speakers in which the moving element is just a thin ribbon of metal foil. As the first step towards building a set of ribbon headphones, [JGJMatt] has designed a compact ribbon speaker made from aluminum foil.

A 3D-printed body holds six permanent magnets, which produce the static magnetic field necessary for the speaker to work. The sound itself is produced by a corrugated aluminum diaphragm made by taking a strip of foil and creasing it with a gear. Aluminum is difficult to solder, so electrical contact is made with a couple of short segments of copper tape. A little Blu Tack and glue hold it all together, and the result is stunning in its simplicity.

Boosting Headphone Volume with a Tiny Smartphone Amplifier

This video guide from GreatScott! explains how to build a tiny Class A amplifier for your smartphone to boost headphone volume.

As the name suggests, an amplifier is a device that increases the amplitude (the power) of an electrical signal. Amplifiers can be used for any kind of electrical signal, but audio amplifiers are the most well-known. As an example, the audio output from an electric guitar is very faint, because that signal is produced entirely passively by the electromagnetic pickups. To push that up to a respectable volume, an audio amplifier is necessary. If your headphone volume coming from your smartphone is too quiet, GreatScott! explains how you do the same thing by building a tiny amplifier for headphones.

MicroNova’s AmpliPi Is a RaspberryPi Powered Open Source Audio System for Your Entire Home

Driven by a Raspberry Pi Compute Module 3+, this Python-powered audio system supports up to six stereos zones — expandable to 36.

MicroNova has launched a crowdfunding campaign for AmpliPi — an open source, whole-home audio system powered by a Raspberry Pi Compute Module 3+ and running a Python REST API and mobile-first web application.

“AmpliPi is a multi room/zone home audio controller and amplifier made for whole house audio systems with many zones,” explains MicroNova co-founder Jason Gorski of the device. “It can play up to 4 simultaneous audio streams (Pandora, Spotify, AirPlay, etc) or sources (RCA inputs), each routed to one or many zones, all of which are configurable in real-time using the self-hosted AmpliPi Web App or its underlying REST API.”
