I’ve been interested in tracking my own sleep too. I wonder how useful these commercial products are in producing data that is correct. They come from technology companies who primarily want to collect data, as much data as possible. They’re not at all interested in providing their users with an honest interpretation of anything. A lot of them probably don’t even have the expertise to interpret whatever they’ve gathered.
I’ve been involved in sleep studies in the past and none of them involved using a smart-watch or other commercial wearable. They used electrodes (?) that were stuck to my body and fed into a computer. What data was being collected and how to properly interpret that data is beyond me.
Making a DIY device is probably feasible, but again, I wouldn’t have a clue on how to interpret the data gathered. I don’t think it’d be too complicated though.
Tools built specifically to monitor one signal are probably better than a generalized thing, such as a smartwatch, from a company that produces surveillance equipment for marketing purposes.





You write entirely dishonest trite! That ‘revolution’ was preceded by the Gwangju Uprising, a massacre. The protestors retaliated with violence. It is this history–the threat of violence–that underpins ANY political power. There are no peaceful revolutions. Anyone who attempts to frame something as peaceful to prove that there is such a thing looks at an event myopically and dishonestly.
Read your own fucking articles. There’s nothing peaceful about killings and torture. “On June 11, the National Police Agency defended its actions on the previous day, describing rallies as illegal, and as violent “disorderly conduct”, and declaring their intention to crack down on further unrest.” You: but-b-b-but it was a peaceful protest. You are a liar and a bootlicker.
