Re: Introducing myself / Where to buy PCBs?

Alessandro, 

It looks to me like only their custom board service is going to be
discontinued. It does not affect either unpopulated or pre assembled openeeg
boards.

Anyway, if you are getting the pre-assembled ones:

1. Case and cabling. Most important of all; make sure that the proximity of
the 2 boards does not compromise the electrical isolation of the dc-dc
converter, either directly or via any fixings that are used.

2. Get proper silver/silver chloride electrodes. I wasted a lot of time
thinking I could make some. Get gel and preparation gel too. 

 

I'll probably write some more later (I have some notes somewhere) but got to
run for now..

Thank you all for the useful information. I confirm it's still possible to
buy the boards from Olimex, but I think this would not be possible any more
after the 17th of September (it's written here:
https://www.olimex.com/PCB/). The other good news is the process is now much
more easy than it was described in the guide. Instead of writing the email
you can just buy your PCBs here:
https://www.olimex.com/Products/EEG/OpenEEG/


 

So next steps are: (1) case and cabling, and (2) electrodes. Anything I
should pay particular attention to?

My best,
Alessandro

Hi Alessandro,

Their website suggests that everything is still on sale. Where did your
information come from?

They do say they will be on holiday though from August 3rd - 18th, so will
not be shipping between those dates.

You could get another PCB manufacturer to make the boards, but it would be
more expensive and possibly prone to error. The Olimex ones are known to be
good.

Also, you say you have no hardware experience, so I would recommend strongly
that you buy the pre-assembled and tested boards form Olimex. I have a lot
of hardware assembly experience but I still bought the readymade boards, it
saved a LOT of work (parts sourcing, assembly, programming, testing). You
would also need a programming cable and software...

Good luck & Regards

Paddy

Subject: [Openeeg-list] Introducing myself / Where to buy PCBs?

 

Hello there,

My name is Alessandro, I am 24, I live in the United Kingdom and I have
absolutely no idea is someone is interested in these information.

 

I joined this mailing list because I really would like to build my own EEG
machine (I am a MSc student, my major is computational neuroscience).
Unfortunately I have no experience with hardware. My first question at the
moment regard where to buy my PCB. I know Olimex is listed as suggested
shop, but apparently they stopped selling PCBs at the moment. So, my
question is: sending the specs (ModularEEG BOM v1.1 EU) of the PCB to
another shop would do the job as well?

 

My kind regards to all of you,
Alessandro
