Connecting Ethernet Through Eurorack Modular System
The NSA Selector, a fascinating new Eurorack module from wenzellabs, offers a novel approach to network exploration. Designed for use when computers are connected via Ethernet and WiFi is deemed unreliable, this module converts Ethernet signals into audible noise [1][2].
At its core, the NSA Selector takes raw Ethernet network traffic entering through one RJ45 jack and forwards it unmodified to the other jack. Simultaneously, it feeds the digital signal into a simple digital-to-analog converter (DAC) that turns the raw binary Ethernet signals into an audio waveform. The resulting audio output, delivered through a standard audio output jack, is essentially the direct sound of the digital Ethernet signaling without any decoding into usable audio formats [1].
This unique device acts as a network tap that passes Ethernet data transparently but also captures the electrical digital signal and renders that as an audible waveform via DAC, creating a novel way to "listen" to network traffic as raw electronic noise suitable for Eurorack modular synthesis [1].
The NSA Selector, however, does not play digital audio formats. Instead, it produces a noisy, digital-sounding audio stream that can be manipulated or explored within a modular synthesizer setup as a unique sound source [1].
While listening to raw signal noises might not be appealing to everyone, it is common in Eurorack usage. The NSA Selector, with its pair of RJ45 jacks for Ethernet cables and a single audio output jack, fits perfectly into this niche [2].
Intrigued? You can hear the final product in action at 25:46 in the video provided by [mazzoo] below. And for those who appreciate a bit of humour, the NSA Selector features fun jokes and references on its PCB [2].
However, if one is interested in nice sounds, they may not find the NSA Selector appealing. But for those seeking a unique and innovative approach to network exploration, the NSA Selector is certainly worth a listen.
The NSA Selector, despite not playing digital audio formats, comes with humorous references on its printed circuit board (PCB), demonstrating a fusion of technology and entertainment. As for the music generation, the raw digital Ethernet signaling converted into an audible waveform serves as a unique and intriguing sound source for the synthesizer, offering a fresh perspective on music technology.
