Frequently Asked Questions


PsyLink is experimental hardware for reading muscle signals and using them to e.g. control the computer, recognize gestures, play video games, or simulate a keyboard. PsyLink is open source, sEMG-based, neural-network-powered, and can be obtained here.


The main author quit his job to work full-time on this project, so naturally it can only go as far as his funding will take us :) If you like what you see here, please consider supporting this project by donating:


Ultimate Goals

The nature of this project is explorative, so there is not an ultimate goal yet, but I have the following keystones:

Short-term goals and possible next steps are outlined on the "Next Steps" page on the PsyLink wiki.

There's a wide range of possible applications, including:

You can absolutely get your own PsyLink, and there's a special page just for that.


This project is so multifaceted that you can help in a lot of different ways, from pointing out typos or design flaws to contributing code or assembling psylink prototypes. Whatever you find interesting and worth your time :)

Good starting points are:

And finally, just telling your friends about it already helps a lot :)

Why not use Twitter/Github/...?

This project exists in the first place because for-profit companies with centralized services have failed to deliver. For example, the "Myo" was a device similar to the PsyLink, but when the Myo leadership saw a profit opportunity, they abandoned the Myo community and pulled the device from the market.

Just like the Myo, GitHub is a centralized product in the hands of a profit-oriented company, Microsoft. The same goes for Twitter, YouTube, TikTok, Reddit, Discord. These services take power away from the community and give it to corporations, which may simply take away your access to those services (e.g. through sanctions or unjustified bans), add undesirable features (e.g. advertisements, fear-mongering recommendations, dark patterns, demanding private information like a phone number), or just shut down the service entirely.

Therefore the initiator of PsyLink dared the experiment to use services that are decentralized and community-owned. PeerTube instead of YouTube. Mastodon instead of Twitter. Gitea/Codeberg instead of GitHub. Matrix instead of Discord.

The disadvantages are clear: The more users are on a platform, the better the project will spread. But from experience, the author found that if the project is good, it will spread by word of mouth anyway. Organically and authentically.
