The video, hosted by Deepak Ajay from Upside Down Labs, provides a step-by-step guide on how to record bio-potential signals using the Backyard Brain Spike recorder and biometric hardware. The video covers the recording of ECG, EMG, EOG, and EEG signals.
The process begins by visiting the Backyard Brain website and downloading the Backyard Brain Spike recorder software. After installation, the software is connected to an Arduino board, which is then connected to the biometric hardware. The hardware is used to record various bio-potential signals, including ECG, EMG, EOG, and EEG.
The video demonstrates how to adjust the settings of the software to record these different signals. For instance, to record ECG signals, the software settings are adjusted to a band pass filter for recording with a frequency of 4 Hz to 40 Hz. The same process is applied for EMG signals, with frequency settings adjusted to 74 Hz to 740 Hz.
For EOG signals, the video demonstrates how to adjust the settings to a signal of 2 to 10 Hz. The video also provides a demonstration on how to record EEG signals, with the software settings adjusted to a frequency from 4 Hz to 14 Hz.
The video concludes by emphasizing the potential of these bio-potential signals in DIY neuroscience and bio-potential recording.
