How can I see my EEG signal in computer?

Hello, I have make a homemade EEG active electrode. Now I want to see my scalp’s signal on my laptop with a free software. So I mean there are no need any extra hardware right? Also which software will be best for this purpose?

Hello @saiful,
Generally signals from an electrode (active or passive) will need to be amplified and converted from analog to digital at least before they can be sent to a computer.

Could you let us know a bit more about what you’ve built? That will make it easier to discuss what additional hardware or software might be needed.
