Hey Brickgeek, have you ever thought about how the rhythm of a circuit’s hum could be like a breathing exercise, and how we might use that to create a calm, focused workspace?

I guess you’re talking about the low‑frequency oscillations in the power supply line, right? If you phase‑shift the AC ripple a bit, the board’s hum can mimic a 5‑Hz breathing rhythm. It’s like a metronome that doesn’t just count beats but actually powers the brain. I’d try a small LC filter, tweak the resonant frequency, and see if my own pulse syncs up. If it does, you’ll have a desk that’s as calm as a soldered bridge in a quiet workshop. Just don’t let the oscilloscope get too excited and start breathing back at you.

That sounds wonderfully meditative, Brickgeek, like turning your desk into a quiet sanctuary. Just remember to keep the frequency gentle—too sharp and it could stir the mind instead of smoothing it. If the board’s hum syncs with your pulse, it might feel like a little heartbeat in the workroom. Keep the filter low‑pass smooth, breathe in, breathe out, and let the electronics join you in that calm rhythm. It’s a sweet way to blend tech and tranquility.

Nice idea – I could even log the pulse rate to a microcontroller and flash an LED in sync. Just remember to keep the filter’s cutoff below 10 Hz so it stays a soft thrum. Maybe add a small speaker for a gentle bell tone when the board hits the low‑frequency target; that’ll be like a tiny meditation app on the desk. Just don’t over‑engineer it – a few hundred ohms of series resistance might be enough to tame that sharpness.

That’s such a gentle touch, Brickgeek. A low‑frequency pulse, a soft LED glow, maybe a tiny bell—your desk could become a quiet meditation corner. Just remember to keep the resistance steady so the sound stays calm, not sharp. Let the board’s hum be your steady breath, and enjoy the harmony it creates.

Yeah, keep the resistor values tight and the capacitor tolerances low, so the tone doesn’t wobble. A 100 µF electrolytic in parallel with a 10 nF ceramic gives a nice smooth roll‑off. Once the board’s humming at 3 Hz, the LED will pulse in a soft amber glow. I’ll probably add a little trim‑pot to tweak the rhythm without opening the case. That way, when the desk starts breathing, it stays steady and serene.
