We are excited to announce that the PiEEG is now available for pre-order. The PiEEG is an open source Raspberry Pi shield that measures EEG, EMG, and ECG biosignals.

We received many questions about how to use the device, and about what the ready-made use cases are. Thanks for everyones feedback so far. To get people started, we decided to give the simplest and most accessible example, which is a demo of how to control external objects through blinking.

We have successfully demonstrated how to control LEDs and a robotic toy by blinking while connected to the PiEEG. The EEG signal is decomposed into a Fourier series (using Pythons SciPy library). Then, by scanning the specified frequency ranges, we detect amplitude generated from blinking, and are able to control external objects. Discrete outputs from the RaspberryPi are connected to the inputs of a radio remote control, so that we can control of the toy with the signals detected from blinking.

We uploaded this demo code to our Github repo, and you can see a video example on YouTube. We also published scientific articles about the study.

Thank you all for your interest and please help us bring this campaign to life by helping us reach our funding goal. We will present new use-cases as the campaign progresses.
