I wonder if Functional Near-infrared cerebral spectroscopy[1] could be used instead of an EEG to make this work, it might be a lot easier, and cheaper... you could sew it all into a hat. Apparently the main thing you need is a Pulse Oxygen Sensor.[2] [1] https://openfnirs.org/ https://openfnirs.org/ [2] https://www.analog.com/en/products/max86141.html https://www.analog.com/en/products/max86141.html

If you want to target alpha oscillations, fNIRS is not sufficient, it measures oxygenation changes in the blood, which is a delayed metabolic response to brain activity, changing on the scale of seconds. EEG oscillations instead reflect real-time neuronal electrical activity, changing on the scale of tens of milliseconds. On the plus side, you can also sew EEG into headbands, there are a lot of wearable devices under development.
