The device is controlled with a simple rotary encoder to set the alarm and a button to toggle it on or off, with custom alarm sounds configurable through a small local web server. The original Reddit post gained around 1,100 upvotes, and the creator may release the source code and 3D printing files if there's enough interest. ## Full article daily.dev links to this article rather than hosting it.
