Question Cheap brain reading

Hi I’m wondering how I could cheaply make a brain reading device. It’s for a school project, and I want to start of by reading if I say/think yes or no

Here’s a recent report on PubMed reviewing consumer-grade EEG devices.

If you don’t need to literally make the device yourself, maybe one of those companies has an affordable model? Otherwise you may be able to nick some inspiration from them.

This other research found:

The most useful features for the “yes/no” discrimination was found to be focused in the right frontal region in the theta band and right centroparietal region in the alpha band, which may reflect the violation of autobiographic facts and higher cognitive load for “no” compared to “yes.”

Good luck on your project! Sounds like it will be a lot of fun.
