[Health] [OLPC-GSoC] first prototype of working EKG around the XO (was health project in GSoC 2008 )

Tue Mar 25 18:47:02 EDT 2008

Hi All,

Awesome progress! Glad to see someone else moving forward on this. I've been
down for a few weeks due to medical procedures and my education but I'm very
eager to collaborate on this effort. I'll keep in touch and I should be back
to part time devel soon enough.

Best wishes,
Ian Daniher
