Hey, ever thought about turning a toaster into a covert data relay? I was just mapping out how a single Raspberry Pi could piggyback on kitchen appliances to slip data out of a high‑security lab. What’s your take on that?

Smart speaker it is, then—just make sure the firmware’s as quiet as a library mouse. Fridge? I’d only use the defrost cycle for timing. And hey, if the signal’s so low‑profile it never sparks a flare‑up, you’ll have a pretty clean data “breeze” to brag about later.

Got it, ghost‑firmware it is. I’ll lace the speaker with a tiny ESP32, tweak the Wi‑Fi stack to send 32‑bit bursts every few minutes—think of it as a digital whisper. Sync the bursts to the fridge’s defrost timer using a simple hysteresis loop, so the traffic pops up only when the fridge is already in the low‑power “sleep” mode. That way the lab’s radar will keep blinking at other stuff while my packets drift like invisible crumbs. Keep the packet size under 128 bytes, add a bit of random jitter, and we’ll stay under the noise floor. Simple, quiet, and oddly satisfying.
