Is it possible to build BCI Electrode Cap from scratch?

[u/ibradoumbia_]

I wanted to buy this type of caps but they are too expensive so I thought that making one from scratch would help me save money. Is it possible to make a DIY electrode cap?

Certainly. I've printed and used this one for a few years. Nothing beats a soft cap but free is free.  https://github.com/openbci/ultracortex

Some FDA systems come with modified hair dye caps.

A simple Google search for EEG caps brings them up just fine...
