This first video is me recording my forearm tremor before applying the electrical neurostimulation. I’ll run a Discrete Fourier Transform over this data to provide a snapshot of the spectrum of my tremors.
Here is a rather longer video of the device in action edited down to leave out the long gaps between the minutes.
Apologies but the video is too large for blogger to upload so here is a link to it on YouTube
Here is the DFT of before:
and here is the DFT after 15 minutes of electrical neurostimulation.
Technical details and how to build your own device can be found here.
