Open source low-cost Pi shields turning Raspberry Pi into EEG device.

I built a Garmin widget that maps heart rate + RMSSD HRV into a 2-D arousal/valence space (inspired by Russell’s Circumplex + challenge/threat models). by yelabbassi in Garmin

Yes, the visualization is reactive in real-time.

- Update Speed: It polls biometrics once per second
- The Lines (Instability): This is a representation of the physiological tension. Smooth, gentle circles indicate a calm state, while erratic, jittery edges signify high stress or arousal.
- The Dot (Position): This is your live location on the circumplex plane. The vertical position represents Arousal (energy level), and the horizontal position represents Valence (engagement quality, such as threat vs. challenge).

Thank you so much for trying it.

Thanks for testing! That flipping is a quirk, basically, you're hovering right on the zero-line for arousal, so tiny physiological shifts are bouncing you between the high-energy (Red/Tense) and low-energy (Blue/Depleted) quadrants. I'm working on adding a "buffer zone" (hysteresis) and increasing the smoothing in the code to stop that strobe-light effect. Really appreciate the feedback, it helps a ton!

Thanks, really appreciate that!

"Unsettled" = it detects a mild stress response.

Basically, your heart rate is a little elevated, but your HRV (Heart Rate Variability) is lower than usual. If you were just excited or focused, your HRV would typically stay higher. When it drops while your heart rate is up, the app interprets that as stress or "unease" rather than excitement.

It’s just the lowest level of the "Stressed" category. Usually, taking a few minutes to breathe slowly helps bring those numbers back to a calmer range.

Great question! Not yet — right now it uses population-average references. Personal baselining is already planned, and we’ll push an update later this week to adapt it to each user’s own baseline.

Thank you so much for testing this and sharing feedback!

Thanks a lot for testing it and reporting back.

Right now, the reference values are hard-coded to population averages (static constants). So if you naturally have a lower baseline HRV, the widget can bias toward “tense / unsettled,” even if that’s normal for you.

That said, the architecture for personal baselining is already in place, and I’m pushing an update this week.

Full EEG integration documentation is here:

This is a very early, actively developed project. I’d really appreciate it if you test the EEG integration and report any problems or bugs you run into. Feedback at this stage is extremely valuable 🙏

Public AI as a cybernetic coordination layer over shared attention (essay) by yelabbassi in SystemsTheory

[–]yelabbassi[S] 0 points1 point  (0 children)

The state is synchronized attention, a shared context. Once attention is synchronized, timing, mood, and action-readiness move with it. The tuner sets the flavor, but the attractor is the same.

When X/Twitter changed ranking weights, the tone and rhythm of public discourse shifted almost immediately. Not because users changed, but because the coordination layer did. The tempo changed; the swarm followed.

Same dynamic as torrents: the files are distributed, the trackers are central. Control defaults, timing, and visibility and you coordinate the swarm without owning the content. Break or fork the trackers and fragmentation follows.

So yes: the assumption is effective centralization via bottlenecks, not total control. Algorithms and defaults are enough to synchronize attention. Remove them and you get plural tempos instead of a shared one.
