PsyLink P9.2 Labeled Sample Signals

This video shows the calibration process of [PsyLink P9.2](https://psylink.me/p9.2). In the first part, the user records various arm movements and at the same time labels them with key presses, so that a neural network can be trained on the sample data. In the second part (starting from minute 7), the neural network is being used to predict the key presses based on the arm movements, with mixed results. The resulting data set can be found here: https://codeberg.org/psylink/psylink-datasets/src/branch/master/2023-03-05_spelling_out_hello
