Back in the workshop for a day this week doing some 'proper' technical work using screwdrivers and soldering irons.
The task was to take the Emotiv toy EEG headset which uses a wireless link back to the recording software and modify it so that a proper high quality EEG electrode cap could be used wirelessly, thus freeing the participant from being fixed to the chair by the umbilical cord of electrode wires.
The caps we are using for this are supplied by EasyCap who also provide complete and detailed instructions for ripping the guts out of the Emotiv headsets and hooking them up with their caps.
For once the instructions are actually written by someone who knows what they are doing and are clear and easy to follow. A couple of very minor points of deviation from what actually turned up with the kits, but nothing that can't obviously be worked around so long as you are looking ahead.
The Emotiv wireless link only provides 16 channels, but it'll be interesting to see what the researchers can do with that now they can put their participant in the real world instead of strapped to a chair in a cubicle.
A simple job satisfyingly finished. Nice to get back to dealing with physical stuff.
