FreeEEG32's early history and a cool demo

by Joshua Brewster

Hello once again.

First off, thank you all so much who’ve backed our project already. You’re awesome and your support goes a very long way.

We wanted to show you some of the 19 channel headset data live streaming this week, but we are still waiting on some more footage. Instead, we are going to show you some of the process that went into creating the FreeEEG32.

Dmitry designed this project all by hand in Russia by himself. Since 2016, he’s been working on the project by hand-etching his own PCBs (including hand-soldering the first several of the boards you see advertised), using free samples from manufacturers, and developing experimental but functional setups including ECG, 64-channel Linux boards, and tACS (transcranial Alternating Current Stimulation) - which has since turned into a formal undertaking to help a group of developers in India.

You can see he even came up with his own handmade 32-channel headset design using pogo-pins soldered to grommets sewn into neoprene, which you can ask Dmitry about as a potential low-cost headset option.

Lastly, here’s another video by Dmitry showing off 32-channel, 8-12 Hz coherence being used to modulate an abstract art neural network:
