It seems you hook this up to your friend's head, then program them via the STM32F7. Their body becomes your robot. Bwahahahahahaha! I guess you chose the STM32F7 because it has floating point, which means you can make your new robot's movements ultra-smooth and precise.

I'm joking. What I mean to say is... could you please add some detail in the project description so that hackaday peeps can know what this is, what it is supposed to do, and how it works?

Even some links would be a start.

One colleague made measurement system for oil refining machines with similar configuration of ADC and MCU. But i making FreeEEG32 alpha2, and alpha is result of what was working in distinct components of prealpha. Here can be link on previous project FreeEEG32 alpha1 https://hackaday.io/project/20618-freeeeg32-32-channels-electroencephalography and in alpha2 i will fix all bugs which was found in alpha testing. Here how alpha2 can looks like https://github.com/neuroidss/FreeEEG32-alpha2/tree/master/KiCad/out/3d

on base of FreeEEG32 prealpha2 can be organized course of assembling on its base -- brain-computer interfaces

  Are you sure? yes | no
