hi morritz
what you prefer to work on right now ?
again if you would ask ask me - it's best to work
on our current design .
we are very close to finishing (only ir interface and maybe some
change for safety) .
already now we probably could sell it to more then 50 people (group
members ) -even without fcc -and i think maybe many more with the
right legal advice .
(we just have to check real carefull for safety -or maybe compare to
safety of brainmaster etc...)
of course maybe testing etc ???
so really pretty soon , i think we could have some very good
result !!!
and about the ti's design :
i think after talking with sanjay and reading little about medical
devices - i think that this idea of eeg/emg/ekg with open source
software and maybe some adaptions to be sensor interface -
could revolutionize the medical market - so his potential is much
more great then we ever though!
so we would definetly do it - maybe even in paralelel ?
what you think ? get more people to work on ti's design ?
but anayway again my feeling is that we can't leave the old version-
we must finish it !
what do you think?
and in any case our situation is very good i feel !
we will surely acomplish alot more then we ever dreamed!
cheers , dude
yaniv v.
p.s. please forward to jeorg , and any other person resposible for
cuirrrent version .
