Progress and Accomplishments
This week I was focused on three primary things, getting initial parts ordered so we can start some testing, looking into possible headset 3D files so we can have a consistent frame for our electrodes, and looking into the DSP and software interface skeleton of the project.
For parts we wanted to get the electrodes ordered and out of the way. We ended up going with the supplier for OpenBCI which is Florida Research Instruments.
For the headset, I found the 3D File OpenBCI uses for their headset and am working to get it sized correctly. I am also working on designing a spring loaded mechanism that will ensure electrodes maintain full possible contact with the scalp.
Lastly for the DSP and software interface, I was focused on the microcontroller aspect specifically the ADC->ESP32->Computer interface. I found some solid options on how to do it, and plan to work on it further next week.
Next Week
The main goal of next week will be to finalize plans for the ADC->ESP32->Computer pipeline and start drafting an MVP we can use for testing.
