Whether you work with CAD design software or edit videos, keyboard shortcuts can really speed up your workflow. Dedicated macro keyboards take this even further by moving the most frequently used commands to individual buttons. While these keyboards are widely available both as commercial products and as DIY projects, they usually are restricted to a predefined set of functions like media controls. There are some exceptions: The Elgato Stream Deck is a keyboard with a cleverly integrated LCD touch display behind transparent buttons. Each button can be configured to have different functions and icons depending on the application you are currently using. Considering the high cost of these devices I set myself the goal of creating a cheaper DIY alternative that is fully configurable.
