Where to start with EEG, without hardware?
Hi. I have problem because I saw few films and read few blogs about EEG and BCI. I would like to start with it (You know Iron Man, control a small car or drone, play game like pacman only using only brain). But I have some problems:
1. I have not enough money to but Cyton (Now I try to save some money but I do not earn in $ so it will take some time to save enough)
2. I don't know if I can build it by myself. I have some experience in electronic but probably not enough - is there any bootcamp about it in Europe?
3. Is there any good and easy resources to start without equipment? I know that it will be not as good as do something on my own data from my brain but it will be a good start I guess
I would be really glad for any answer/help. Thank you

Damis, hi.
Apologies for the delayed response. My suggestion would be to purchase the Ganglion, as it is less expensive than Cyton. However if you want to explore building a budget EEG using DIY components, there are a number of articles on using a sound card approach.
https://www.google.com/search?q=audio+card+eeg
Note that computer sound input interfaces typically have a high pass filter associated, such that all frequencies below a threshold (such as 20 Hz) are filtered out / removed. (EEG frequencies are in the range of 1 Hz to around 40 Hz). So any EEG trick with such interfaces must use some kind of workaround, such as (1) removing the filter components on the physical sound card. (2) some type of modulation (AM, FM) that gets the signal out of the filtered range, etc.

Than you so much

Wow, thank you so much
Also, note that a major portion of BCI is signal processing, which you can do with artificial data. For example, you can see http://www.bbci.de/competition/ for a couple of datasets to play around with. For a good theoretical overview, this Youtube series might be useful:
