Hello all,
Though I've been interested in the idea of building my own EEG
machine for quite some time now, I've only recently subscribed to
this group.
I initially came upon the idea a few years ago when I heard about the
BrainMaster and the HAL4 devices.
>From what I can gather, these older designs have been replaced by
what is being discussed on this list.
I'd like to get started building one of these machines, but would
first like a little advice on where to start.
What are your suggestions on which one of these units would be the
way to go? I'm a relatively experienced electronics builder (not
designer) and feel I could handle just about anything short of
putting together an SMT-based machine (no experience there, though
I'd like to learn :).
Can I begin to collect parts for some of the building blocks of these
devices that will probably not go through much changes in the future?
I'd like to begin working on something that I can use in one of these
projects later - if the designs have not yet been finalized. An
input stage? Microcontroller component of a design?
Tell me about some of these:
modularEEG - is this the one discussed here and on openeeg.sf.net?
How complete are the plans to build this unit?
RS232EEG - I've seen some plans for this. Is it doable? Are there
board masks availible? I've heard it needs some safety work... Can
I do without?
ComEEG - <shrug>
GamePort EEG - probably not the way to go I'd guess...
TinyEEG - a Handspring Visor module would be a good place for this :)
HAL4 - is this worth building if I could get the plans and parts
together?
Standalone - Looks easy.... Thoughts?
BrainMaster - the old standby?
I'm also curious about the relationship between >openeeg.sf.net< and
this >buildcheapeeg< Yahoo! group. Is the bbs.circuitcellar.com
local.cci.hal4 list totally dead and everybody has moved here?
NETWORK EEG :
Regarding the discussion above [previous messages] about streaming
EEG data over a network... Is is possible to exploit the modular
nature of the project at hand to make possible an ethernet module
instead of the serial? Just add an ethernet driver and maybe use the
existing uController to pump the data there instead of to a serial
port?
A more advanced design could give one of these units a TCP/IP stack
capable of IPv4/6. Webserver? Wireless?
This would be a fine way to add more "channels." Just put two
devices on the network....
Are USB interfaces for these devices in the works?
I'd be interested in doing some design or circuit testing work as I
have access to some test equipment here at the university. I'm
willing to help develop software as well. I am primarially a FreeBSD
user and would hope eventually to see any availible software that
comes out of this project work on this platform.
Much thanks to all! I hope to get started soon!
Cyrus
