This is bio-cybernetics pure and simple. Adding noise to a communication channel is essential to digital communication. Here the same principle is applied to the vagus nerve, a feedback conduit between brain and soma/viscera.

The vagus nerve is a site of interest for the microbiome too - it’s a conduit between your brain and the ecosystem epi-effects of gut bacteria colonies. Active research indicates mood can be modulated by “reprogramming” (in the metaphorical sense) ones microbiome.

This exploit is far more straightforward and so much more biopunk by its close association with the grinding community

Spore-Spitting Slime Molds Make Great Computer Hardware

From wired:

We’ve long known the slime mold can determine the shortest path through a maze, or even model optimal railway systems. Now, a group of researchers has shown these amoeba-like single-cell organisms could be used to build general-purpose computers.

In a paper published last week on the academic research website arXiv, scientists from the University of the West of England confirm Physarum polycephalum slime molds can act as memristors, a new type of resistor, a key component of electrical circuits. The paper has not yet been submitted to any scientific journals.

Memristors, like resistors, regulate the flow of electricity through a circuit, but they can “remember” a particular charge even when it’s turned off. This means they could be used to create more efficient computer memory.

Recycled Hard Drive Instrument - Electric Waste Orchestra

Creating unconventional musical instruments from outdated computer parts and other e-waste

In the hubbub of Moogfest, we serendipitously ran into a guy wearing purple 3D-printed eyeglasses and holding something that looked like a keytar. Upon closer inspection, and with the house lights turned up, it turned out to be a musical instrument made from outdated computer parts. Colten Jackson wasn’t a speaker at the festival, but a passionate musician who made the trek to Asheville from Champaign, IL, to spread the word about his educational side project, Electric Waste Orchestra. Jackson reuses e-waste to make music in unconventional ways—for example, in this video he transformed six hard-drives and a number pad into a musical instrument (with help from Arduino hardware and Pure Data software) and jams along with a modular synthesizer.
