Hi Tom

This is a great video, thanks for posting it!

Could you please post the link for the wiki page detailing the circuit
details etc, There are many people who would like to try this out! (some
cced here -- Ian, Mel.....)

Also, itd be interesting to start thinking if you would like to build a
customized UI for displaying information. Perhaps something derived off the
basic Measure code ? I'd be glad to help you use the Measure code base and
customize it according to your need. Feel free to post questions on or off
list. (sugar might be a good list to cc on such discussions)

Another idea that I'd like to mention would be to apply such information
into the context of a game, i.e. control events/characters in a game on the
XO based on such input, that can make the process of personal health
monitoring fun ?

The Health mailing list is a perfectly fine for posting such information.
Also, there is a Health Jam coming up soon in April. You might like to
connect with Mel, Seth.... to demo your prototype there if possible!

kind regards
