Playing DOOM On A Receipt Printer

December 27, 2025 by 32 Comments

Gaming is a wonderful thing. Unfortunately for many of us, work takes up our valuable time, which should be allocated to our gaming. What if there was a better way? Well, printers can print an image quickly, and receipt printers can print a lot of images. This sounds like an effective display for DOOM in a pinch. [Bringus Studios] managed to find such a printer and got the classic shooter running.

Getting the printer’s attached computer, which was only designed for printing the cost of your chicken sandwich, to run Half-Life was far from easy. [Bringus] struggled through the process of swapping operating systems from Windows 7 to Linux just to return to Windows 7 after a painful process of maintaining compatibility between 32 and 64 bit software. Driver issues followed through the entire process just to get anything running at all.

But we can’t play DOOM while at work on a normal screen. The printer MUST display our glorious 480p gameplay. To achieve such a workflow, [Bringus] implemented a script to print out a frame of the display, allowing for “visible gameplay”. Along with some heat issues from the nature of thermal receipts, eventually the printer displayed the glory of DOOM.

Playing games on a thermal printer might be one of the weirdest things you’ve seen today, but what if we could reverse the script a bit and create a printer from something else? Here at Hackaday, we have exactly the thing for you: a printer made from a vintage typewriter!

Home Made Half Life 2 Turret Powered By Pi

January 1, 2016 by 7 Comments

To help expand his inter-dimensional empire, [Solderchips] has decided to build his own Half Life 2 turret. This, he hopes, will automatically track and shoot anyone who hinders the work of Our Benefactors. He’s documenting the process, and has just published his first step: creating a 3D model of the turret and printing it out. The final project will use a Raspberry Pi and a webcam to track rebels and fire on them automatically, especially those with crowbars.

He’s made a promising start, using a papercraft model of the turret to build the 3D model, then modifying it to accommodate the brains (the Raspberry Pi) and the brawns, a couple of small servos that will move the top of the turret around. The next step will perhaps be to add a tilt switch so that the whole thing falls asleep if it falls over. The thing to learn from this project, is that at some point you just have to stop thinking about it and actually make something. This paper model is a big step toward success compared to carrying around the dream in your head.

We’ve seen a few Portal Turret builds and a very nice Wheatley build, but not a decent Half Life 2 turret build, so hopefully [Solderchips] will see this through to completion and release all of his files.
