hah! Thank you for the link! Your experience definitely rings a bell -- I'm now a father of a 6 months old and I did my fair share of experiments with Zeo a few years ago. By the way, there is a special firmware going around for Zeo that if installed will store the data unencrypted and also enables sending "real-time" info to the serial port located at the back of the device (I managed to read this data successfully using a python script that was also provided). If you're interested in that custom firmware and realtime data schematics&code and not finding from the web, ping me and I'll look up from the archives! For me wearing zeo more than 5 days in a row became unfomfortable, how long did you use it constantly to get to this 6.30am wakeup time? You mention 18 months but I guess it's not possible to wear the headband for that many months in a row comforably?
