Good news. Over the years (yes - I'm rapidly heading into Old Fart territory so be kind 
) I have collected a lot of stuff. I unearthed 5 AdvancerTechnology EMG boards. Although they only have one channel each it will give me some testing capability re facial muscles. The definately want to go with the OpenBCI board due to it's size thou.
But I can start testing idea's.

Many thanks William. I did some work on the weekend with a friend testing EMG pickup on the face. It work reasonably well with single electrodes. My next step is to try twin electrodes. Many thanks to you and Connor for all of your help. Dave

I also have another post here about the Channel options.. If you could help there it would be really great Again many thanks Dave

Many thanks for that. I'll try that tonight when I get home. As Processing V3 has debugging I want to use that feature to really understand the application, and hopefully beable to preset a lot of the values sent to the OpenBCI board. As I do EMG I…

Hi and thanks for that. I am getting errors regarding this line in Datafile.pde 142 setColumnTitles(tsv ? PApplet.split(line, '\t') : splitLineCSV(line)); 146 setRow(row, tsv ? PApplet.split(line, '\t') : splitLineCSV(line)); It does not like …

Many thanks. I have ordered some from EBay. I noticed that you could also get different pin tips so I have ordered some (crown point) that will grip into the skin a little better than a rounded end. Many thanks for the advice. Dave

Many many thanks for that Conor. I brought the board primarily for the EMG capabilities, and it's good to see others are doing the same. Do you know what happens when the muscle is static but tensed? I am in the midst of another project and so won…

Hi Biomurph. Ok I finally got the time to set up the test system (as described by the docs) and was able to see EKG and EMG. One thing that puzzled me re the EMG was that I could see the signal when I clenched my arm, but the signal then died …

Hi Biomurph. Many thanks for your advice. I am still setting up my workbench for doing experiments (So many projects.. so little space ) Not sure about the acronym SRB?. I am planning to use the P and N as differential so to reduce crosstalk. …

*Happy Dance* Just put in my order for 8 Bit Board and Electrodes. Just a little worried re the USPS as I am not sure if they have tracking etc. Being in Australia it's easier for things to get lost in transit.

For my project - definitely EMG. I tried playing around with the Neurosky chip that was in a Mindwave game. Was able to get both the normal and raw data from it. The big issue with EEG is that it's difficult to get a consistent result in an ad-hoc …

Hi William This is an excellent reference I found too http://csl.anthropomatik.kit.edu/downloads/GibertPruzinecSchultzStevens_OZCHI09_HCIwithEMG.pdf With 8 electrodes they were able to get enough information to get an avatar to display the same em…

Hi WilliamMay thanks for the link. I have read that one before. I'm ok with the acronyms like EMG, EOG and fEMG for specifically the facial muscles. Of interest some marketing firms are using fEMG to monitor the watchers reactions to different …

Though maybe a short form board if one is not interested in transmitting the data via Bluetooth, or not interested in logging the data to an SD card. Myself - being interested in EMG and not EEG I would only be looking at returning a single number …
