Solar Sound Card - ear modular

video upload by Sonic Seed

"A light-sensitive, portable sound generator that extends Ear Modular beyond Eurorack.

Its circuitry responds to ambient light, transforming sunlight, shadows, or small light sources into dynamic sonic textures.

Built for direct interaction with the environment, it invites musicians to listen with their eyes and see with their ears, shaping sound through the shifting presence of light.

Equipped with an integrated speaker and powered by a coin-cell battery, it functions as a self-contained instrument—intimate, mobile, and alive to its surroundings.

Solar Sound Card is a series of light-sensitive sound cards.

Each card reacts to variations in light, transforming brightness and shadow into shifting sound.

Every card includes a built-in speaker, and can also be connected to external speakers via an audio jack.

The audio output provides SP+ (tip) and SP– (ring) signals.

At present, there are seven types of Solar Sound Cards — each with its own character, circuitry, and way of playing.

Explaining Solar installation quantum cloud

"Solar Installation — A Music Box from the Future

Solar Installation is an experimental synthesizer — a bridge between art, sound, and technology. It reimagines how we interact with music, offering a different and deeply artistic way to explore and create sounds.

At its core lies a patch bay that opens up endless sonic possibilities. By experimenting with its connections, you can discover countless “sweet spots” where unexpected textures and tones emerge. The engine itself is alive with movement, evolving harmonics, and shifting layers of sound.

An integrated effects processor lets you transform these tones even further, adding lo-fi echoes, delays, and atmospheric modulations to shape entirely new sonic landscapes.

What truly sets Solar Installation apart is its dual-mode oscillators. Each of the four oscillators can be controlled in two unique ways:

• Precision Mode – using traditional potentiometers for accurate, tactile manipulation.
• Light Interaction Mode – using highly sensitive light sensors that respond to movement and changes in illumination.

This makes the instrument behave like an interactive installation. By positioning it in different lighting environments or allowing natural shadows to play across its sensors, the machine evolves on its own, creating ever-changing, generative music.

Sometimes, it behaves like a futuristic music box — a self-driven system producing evolving patterns, unexpected harmonies, and “happy accidents.” It invites you to let go of control and embrace the beauty of randomness, where sound becomes an organic, living experience.

Solar Installation exists between instrument and sculpture, science and art, intention and chaos. It’s not just about making music — it’s about exploring possibilities.

The Haunted Arcade of the DecadeBridge Triad (Drones, Noises, Glitches and Rhythms)

video upload by Oscillator Sink

"The DecadeBridge Triad is a unique little Synth module that generates drones, rhythms, noises and glitches - it sounds, to me at least, like a haunted arcade in the 80s - malfunctioning machines, wailing, whirring and bleeping. It's based on a trio of analog oscillators arranged in a fairly unique, raw and unpredictable arrangement. It works great as part of a drone or noise setup, makes for excellent sample fodder, and thanks to the neat "reset" input it can play along with drum machines and sequencers (especially paired with a little low-pass gate).

"The Syrmaphone, Canned Sound's original kinetic electro-acoustic instrument, is played by drawing a bow across a series of stereo-amplified metal tines secured to a wooden resonance chamber. This is fixed to a manually rotated mechanism to facilitate portamento performance. The Syrmaphone generates a range of inharmonic, voice-like, other-worldly sounds, atmospheric textures and unsettling audio effects ideal for experimental music, scoring and sound design. Recorded with Soundtoys Little Plate reverb plugin."

"Rare, One-of-a-Kind Sculptural Devices by Paul Tas

These are not your average machines. Designed and handcrafted by artist and inventor Paul Tas, each device in this exclusive collection is either:
• A limited production piece, or
• A completely unique, singular creation—no duplicates exist.

With unconventional, often surreal designs, these devices blur the line between functional object and sculpture. They may serve obscure or symbolic purposes, built more for exploration and expression than utility—think of them as machines that tell stories or instruments for imaginary tasks.

Every piece is:
• Individually constructed
• Visually striking
• Mechanically unusual
• Often part of a broader artistic vision"

Cricket, a musical instrument jewelry that can be played

video upload by 合成少数派 Synthesis Minority

"The Cricket is a solar-powered musical instrument jewelry. It chirps in the sun and can be played by shading. The patterns on its front are not only for decoration but also touchable. The three areas control three oscillators respectively. Pressing them will increase the pitch, change the timbre, and speed up the rhythm. There is also a touch point on the back that will interfere with the output and produce noise. A clip can be attached to the back to wear it on clothes or bags. You can also put it in the grass, and you'll feel closer to summer.

We synth players don't hang Labubu on our bags, but the Cricket 🦗🥳"

Important information about noise therapy !

video upload by errorinstruments paul tas

"It’s important when you start it up that you put the big knob in the middle . This is a trick if you don’t have sound. Because it’s an open chip and it’s circuit bending but we created it that it cannot get broke."



via Error Instruments

"Noise Therapy is a compact, experimental audio device

designed for sound exploration and real-time manipulation.

It’s not just an effect processor — it’s a self-oscillating feedback machine,

a live circuit-bending platform, and a sensor-based sound controller all in one.

• 🎛️ Real-Time Circuit Bending: Dive into unpredictable

sonic territories. The Circuit Bending Bank lets you create new sounds on the fly no

emulation here, just raw, hardware-driven sound design.

• 🔁 Self-Oscillating Feedback: Use it as a chaotic

sound generator or a responsive instrument — capable of evolving drones,

sharp glitches, and alien pulses. • 🎚️ Effect Processing: Process external

audio or internal feedback loops with a rich palette of distortion, delay,

filtering, and noise. • ✋ Sensor-Controlled Sound: A touch-sensitive

and light-reactive sensor beneath the switch opens up expressive

performance options. Interact with light or skin

contact to alter the audio in unpredictable ways. •

🎛️ Patch Bay Exploration: The modular-style patch bay

encourages creative routing and discovery. It’s full of accidents

— those magic spots that only circuit bending reveals. • 🔊 Sonic Range:

From delicate liquid drop-like sounds to harsh industrial noise,

deep ego drones, and intense distortion — this is a tool made for sound designers,

noise artists, and experimental musicians."
