Hello there.

A project log for EyesDrive - Steering with eyes movement

That's my first time using hackaday.io for a project of mine. I usually used it to see all those fantastic projects in there.

About EyesDrive, the signal conditioning circuitry is almost complete. I'm designing the last stages with LabVIEW (at least nothing will take fire if I simulate things, or am I wrong?). I'm currently trying to deal with that baseline drift that affects my signal. I don't know if it's made by those crap electrodes or by some "strange-biological-process" in my body that's drifting my signal.

The simulated stage seems to be working, but the signal is almost unrecognizable, and I don't know if it will work in a long time.

Here's a screenshot of the LabVIEW VI: the last graph shows the processed signal, the first graph shows the raw signal captured in a 20-sec span.
