That’s an intriguing idea, but you’ll need to map out the entire safety protocol before wiring anything. The microbes have to stay under strict temperature control, you’ll need a containment chamber, and the circuit must fail‑safe to prevent accidental releases. Also think about how to sterilize the brewing vessel and how the system will handle variations in microbial growth rate. It’s doable, but the engineering and regulatory hurdles are non‑trivial. Let's outline each step before you start soldering.
