Doom is known as the game that can be played on just about anything. Watches, phones, calculators, and other weird stuff. It can pretty much work on anything that has a screen and even things that don’t really have “screens”.
Twitter user Foone got noticed on Twitter after getting a video of Doom to display on a pregnancy test… but it wasn’t playable. After enough curiosity, they now have Doom playable on a pregnancy test stick. Yes, the little thing you pee on to see if you have to sacrifice the next 18+ years of your life can now be used to kill demons.
Yesterday I had a lot of retweets and reddit posts and such for playing Doom on a pregnancy test.
But as I explained then, it wasn’t really PLAYING on a pregnancy test, it was just a video being played back, not an interactive game.Well, now it is. It’s Pregnancy Test Doom! pic.twitter.com/Nrjyq07EVv

So, here’s how they did it. They bought an Equate digital pregnancy test and replaced the screen with a small 128×32 pixel monochrome display. They also had to replace the microcontroller as the CPU can’t be reprogrammed.
“The existing CPU can’t be reprogrammed and the existing LCD can only show 4 things, so I had to replace both to make any changes. And the current version doesn’t even fit into the shell! (although I’m certain it will when complete)” said Foone in a Twitter post before getting Doom up and running.
After enough tinkering, Doom is now playable with a keyboard. It’s not using any of the actual pieces within the pregnancy test to run it but it is literally *on* a pregnancy test stick. Sadly, you can’t pee on it to play Doom. That said, Foone is working to try and get a keyboard that works by… peeing on a pregnancy stick. So, that’s neat I guess.
