sleep stage time calculation from detailed compliance data

Fascinating links - this neuro link gaming device was a lot lower cost if I recall correctly, but it seems to be no more:

USB Neural Impulse: http://www.newegg.com/Product/Product.a ... 6826100006

I remember discussing the Zeo device with others and the risk of exclusively cloud storage for data and processing.
The github link I assume means that those with either original or new devices in that name can be used with local processing?

Still, the question is whether an inexpensive neural device could add enough data to corroborate breathing-based estimates of time in various sleep stages, particularly if some neural devices claim to calculate this on their own for those without CPAP machines.

(and yes, it was the ~2013 news that led me to believe that Zeo was gone - I guess they came back!)

How inexpensive is "inexpensive"?

breathing-based estimates of time in various sleep stages

IMO, to get even a rough idea of sleep quality, you need a device that looks at eye motion, EEG, heart rate variability and movement (actigraphy).

If you're looking for more detail (specifically, sleep continuity)(which, if you're having issues, is probably more important that rough totals of light, deep and REM sleep) then I'd get something like OpenBCI.

If you're trying to do this by downloading a free "app", GFL.

FYI if you do decide to go the OpenBCI route, be cognizant that these devices are not FDA cleared.

You are going to have to assume risks associated with experimental equipment.

And you aren't supposed to change your machine settings either!

Aren't we just a bunch of scofflaws!

I have experimented with homebrew tDCS so I am happy with the risk levels involved for myself.

Self experimenting is one thing but I wouldn't have attached those electrodes to someone else.

The OP just needs to be aware of the risks and assess the amount they are willing to onboard.

That's great, but Ganglion is not tDCS. It's EEG.

The crux of my warning is that there are risks associated with attaching electrical devices to one's body.

The OP needs to aware of the risks and act accordingly.

For one, I wouldn't be comfortable with the USB attached device OP linked at newegg. If there was a fault, the voltage and current involved can possibly be lethal.

Especially considering the state of some of the dodgy cheapo USB power supplies.

Does anyone have a link for making a hat out of Reynold's Wrap?
