There are a number of hobbyist steno keyboard designs out there, and my goal with the Peridot is to make one that’s easy to build (hence I used basic through-hole components throughout) and open source. How much it will cost will depend a lot on the specifics of the components you choose, but it’ll be vastly cheaper than a professional stenotype. Feel free to make, sell, remix, etc.; this is my attempt to give something back to the Plover community.
What a cool project for a hobbyist keyboard builder! If you make one, feel free to share it on the Hardware Showcase channel of our Discord!
