The original PlayStation debuted in 1994. You probably still have one in your closet somewhere. Well, if yours is not working and you want a project, you can turn it into a clock, just like Twitter user @Rurue0111.
All you have to do is remove the electronic components from the case and add a clock motor inside. The good thing about the PS1 is that the disc cover is already the shape of a clock face.
The dot-matrix numbers here were painstakingly added using a drill. It even lights up when you hit the power button, which looks awesome at night. What time is it? One. PS One.
