I find it difficult to believe that a sleep mask exists with the features listed: "EEG brain monitoring, electrical muscle stimulation around the eyes, vibration, heating, audio." while also being something you can strap to your face and comfortably sleep in, with battery capacity sufficient for several hours of sleep.
I also wonder how Claude probed bluetooth. Does Claude have access to bluetooth interface? Why? Perhaps it wrote a secondary program then ran that, but the article describes it as Claude probing directly.
I'm also skeptical of Claude's ability to make accurate reverse-engineered bluetooth protocol. This is at least a little more of an LLM-appropriate task, but I suspect that there was a lot of chaff also produced that the article writer separated from the wheat.
If any of this happened at all. No hardware mentioned, no company, no actual protocol description published, no library provided.
It makes a nice vague futuristic cyperpunk story, but there's no meat on those bones.
Found that in seconds. EEG, electrical stimulation, heat, audio, etc. Claims a 20 hour battery.
As to the Claude interactions, like others I am suspicious and it seems overly idealized and simplified. Claude can't search for BT devices, but you could hook it up with an MCP that does that. You can hook it up with a decompiler MCP. And on and on. But it's more involved than this story details.
So yeah, a product exists that claims to be a sleep mask with these features. Maybe someone could even sleep while wearing that thing, as long as they sleep on their back and don't move around too much. I remain skeptical that it actually does the things it claims and has the battery life it claims. This is kickstarter after all. Regardless, this would qualify as the device in question for the article. Or at least inspiration for it.
Without evidence such as wireshark logs, programs, protocol documentation, I'm not convinced that any of this actually _happened_.
