Hello all, Back when I had much more time and less knowledge, I was working on designing a similar device. While the design didn't progress into a prototype due to lack of interest by other developers and lack of knowledge on my end, there's a large wikipage on TeleHealth_Hardware that's available for other people working on similar projects to add to. Could everyone working on a health-related peripheral go to http://wiki.laptop.org/go/Health_Hardware and add a blurb. This is a great place for people to post technical resources as well. Thanks, -- Ian Daniher OLPCinci Repair Center Lead OLPC Support Gang Volunteer
