What am I doing

What am I doing...

Building, making an EEG is sooooooo difficult, and not cheap at all.
Buying a pre-maid device would be cheaper I guess, and better.
But still, too expensive.
I am not a producer to make such devices.
What should I do.
I want something fun.

This is $300, and it detects your facial expressions. and has 14 sensor within a headset. But it only give a pc version of software.

This is Cheaper. $200, gives a mac version software, but it has only 1 sensor, and more simpler.

I prefer Emotiv, but it is not for mac.
But, it is not my intention to use these pre-made- correct sensor.
My idea is just an idea, to be fun, imaginative.
I guess I should not use these.
