Design sharing

Hello, it's me again. :) So, I've almost finished my modded EEG-SMT's PCB
design. And I have question. I know there is creative commons sharealike
license, so I want to comply to it, where can I share it so everyone would
have access to it and could be found easily, when searching on OpenEEG site
or Olimex site? Should I send it to Olimex or is here some Admin of OpenEEG
site? :)

I know it is not perfect design and I would really appreciate everyone's
fruitful insigh and what could be placed better or connected differently.

*Main features of this mod are:*

   - *easy manufacturability*


   1. a lot less vias (45>) and vias are big none are under parts
   2. used 0803 resistors and ceramic caps
   3. fairly thick routes, ~60% are 1mm thick


   - *the same dimensions and mounting holes (different connectrors though)*
   - *supporting expansion module, (possible up to 8ch, but firmware tweak
   needed, possible change of baud rate, otherwise 6ch are officialy supported
   by the firmware)*
   - *separate power delivery and communication with device*


   1. possible bluetooth module or different UART compatible device
   2. beware, no protection included, if using direct connection to PC it
   is needed for safety to use some RX/TX protection circuit! I will design
   some later...
   3. possible to design, hardware/software (configurable with switch or
   jumper) power/data flow control, hardware with some FET, software with
   firmware mod, detecting if there is voltage on PWR pin in ComMod header


   - *power delivery through microUSB*


   1. beware, no protection included, need for external module if
   connecting directly from power source or through some device (will design
   later)
   2. easy connectibility to generic powerbank; powerbank (battery) =
   protection and stable voltage


   - *using 14pin (Extension Module) and 6pin (Communication Module) IDC
   90° header*


   1. fairly easy to get by, easy to use
   2. using ground or +5V to separate signal cables = less noise


   - *SOP 8 INA ready instead of SOP 16 INA114*


   1. still need to do some research,  that if there is need for changing
   values of some caps, resistors, but everything is set to go
   2. possible to use for example INA128


   - *using cheaper gold plated 3,5" jacks (although less conductive than
   silver plated, these does not corrode) type PJ-327a*


   1. can be bought on aliexpress for amazing prices
   2. Manufacturer's web page
   <http://www.asia-atom.com/en/Pro_view.aspx?ProductsCateID=248&CateID=248&ProductsID=517&showCateID=248>
   3. ...I will test them and maybe I will change them...


PLEASE feedback would be appreciated, I still think, that something is not
ideal in my design...

I will finish my first version tomorrow (28.7. CET) so please stay tuned! :D

Thank you.
