If you have been patiently waiting for the arrival of the PiEEG shield on the Crowd Supply website you will be pleased to know that is now available to purchase. Allowing you to measure ECG bio signals using the a Raspberry Pi mini PC equipped with the PiEEG shield. Check out the presentation video below to learn more about what you can expect from the new shield specifically designed “to convert Raspberry Pi in to a brain-computer interface“.
Raspberry Pi PiEEG shield
“PiEEG is an open source Raspberry Pi shield that measures biosignals such as those used in electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG). PiEEG is versatile, easy to work with, and compatible with different types of electrodes. Best of all, it was designed to be usable by anyone. To begin measuring bio-signals, all you need to do is connect the electrodes and run a Python script. Applications include gaming, entertainment, sports, health, meditation, and more.”
