Gadgets: Guy runs ‘Doom’ on a pregnancy test and wait, what?

The tradition of running the legendary game Doom on various gadgets and appliances that were not originally designed for gaming is long, but this one takes the cake. 

Foone, a programmer who likes reverse-engineering things and typically works with ancient hardware and software, has managed to run a fully functional game of Doom on an electronic pregnancy test. 

After posting a video of the classic video game running on the tester over the weekend, on Monday Foone upped the ante and released a video of him actually playing Doom on the tester, using a wireless keyboard. 

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

The experience isn’t very pleasant because the pregnancy test has a 128×32 pixel monochrome display (see close-up below), but, amazingly, it works.

I tried zooming in and turning up the in-game gamma a bit, so you can see what’s going on slightly better.

You might be wondering, how the hell is this even possible on an extremely simple gadget such as a pregnancy tester? Well…it isn’t. Foone is cheating a little; he had to replace the pregnancy tester’s CPU and LCD, essentially turning it into a much more powerful computer (still extremely simple by today’s standards, but compared to a pregnancy test or a computer from the early ’80s, it’s pretty powerful). 

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!

Still, the entire exercise is so cool that we had to share. What’s next, Crysis? Fingers crossed.
