I wouldn’t sacrifice a working SNES for this mod, but if you have a broken one in your closet somewhere, transforming it into a digital alarm clock is an interesting (and inexpensive) way to give it new life. As you can see in the video, the display can be set using the standard controller. Plus the cartridge is still removable, making it possible to expand on the mod and develop alternate displays.
