Alien Isolation Tracker Build

This is my build of a mostly 3D printed replica of the Motion Tracker featured in the game Alien: Isolation. As you may know from previous posts I really enjoyed this game and the visual style was awesome. I really wanted to have a go at making one of these, but I never quite got round to it. I made a 3D model of it, did a test print, but never took it further. Then many months later someone asked me to make one for a convention they were going to.

Sadly I didn’t take any photos of the build process, but if I ever make another one I will do a step-by-step of it. It’s not very complex though.

It’s mostly 3D printed, then sanded down and painted. The illumination is from a very simple LED battery circuit running from a simple 9V battery. The coiled cable, carabiner clip and toggle switch on the side I bought from Ebay along with the white and red LED’s I used.

The screen is reverse printed on acetate from a design I made myself based on the screenshots from the game. It’s illuminated by a simple diffusion trick, the mean “screen” area is filled with white LED’s, then crumpled up translucent plastic bags to diffuse the light from them.

When I made this I didn’t really have much experience with doing complex electronics, so the lighting circuit was all I could manage. If I did this again though I’d definitely consider wiring in a soundboard to get the power up sounds and the bleeping from the game on there, there’s plenty of room for the necessary circuitry and speakers.

    Hello. I have tried to contact you countless times by different methods to ask about the Alien Isolation wristwatches. When are you going to make them I would KILL to purchase one. Thanks

      Hi Scott, thanks very much! I won’t ask you to kill anyone just yet (but saving your details just in case). I will be doing a new batch of watches at some point, I’ve saved your email so I’ll drop you a message when it’s time.

    Haha thanks Tom. Naturally, I was only talking about killing Xenos, I never specified Earthlings 😉

      Hi Lucia, can’t say for sure, I’m working on a new batch now but I’m not making any promises as to when it’ll be ready. I’ll add you to my list!

    Wow! A masterpiece. I would love to create one myself. Alien Isolation is by far my favorite game, and it causes one to get attached to things like this motion tracker. Is it possible to get the print files? Or if you ever post to thingiverse, let me know! Thanks

    Hi there, I was lucky enough to be able to purchase one of your Amanda Ripley watches, which I am very happy with.

    I was wondering if perhaps you are going to make this motion tracker commercially available as well? Or perhaps you would be willing to sell only the print files so I could have the main body printed and do the rest myself?

    Or perhaps you would be willing to sell a print of the main body so I could finish the kit?

    Please let me know.

    Kindest regards,
