Low cost open-source hardware for biopotential amplification for neuroscience, prosthetics and more
summary
Describes an open‑hardware biopotential amplifier (BioAmp v1.5) designed to be much lower cost than commercial EEG/EMG systems by converting muscle/brain electrical signals into audio-range signals so they can be captured using a computer or mobile device’s high‑resolution audio ADC. Covers use of existing tools (Audacity, BYB Spike Recorder) and earphones for listening/visualizing signals, and points to the project repository (github.com/upsidedownlabs/udlabsBioAmpv1.5).
