Real-Time ISS Tracker Shows Off The Goods

What hardware hacker doesn’t have a soft spot for transparent cases? While they may have fallen out of mainstream favor, they have an undeniable appeal to anyone with an interest in electronic or mechanical devices. Which is why the Orbigator built by [wyojustin] stands out among similar desktop orbital trackers we’ve seen.

Conceptually, it’s very similar to the International Space Station tracking lamp that [Will Dana] built in 2025. In fact, [wyojustin] cites it specifically as one of the inspirations for this project. But unlike that build, which saw a small model of the ISS moving across the surface of the globe, a transparent globe is rotated around the internal mechanism. This not only looks gorgeous, but solves a key problem in [Will]’s design — that is, there’s no trailing servo wiring that needs to be kept track of.

For anyone who wants an Orbigator of their own, [wyojustin] has done a fantastic job of documenting the hardware and software aspects of the build, and all the relevant files are available in the project’s GitHub repository.

The 3D printable components have been created with OpenSCAD, the firmware responsible for calculating the current position of the ISS on the Raspberry Pi Pico 2 is written in MicroPython, and the PCB was designed in KiCad. Incidentally, we noticed that Hackaday alum [Anool Mahidharia] appears to have been lending a hand with the board design.

As much as we love these polished orbital trackers, we’ve seen far more approachable builds if you don’t need something so elaborate. If you’re more interested in keeping an eye out for planes and can get your hands on a pan-and-tilt security camera, it’s even easier.

It’s 10 PM, Do You Know Where Your Space Station Is At?

I still remember the first time I saw a satellite, I was 12 years old and was camping far away from the city lights. As I gazed up at the night sky, I could actually track satellites with my naked eye as they zoomed across the night’s sky. It was amazing. Nowadays, it’s getting harder to spot relatively small satellites with light pollution from large cities.

The International Space Station (ISS) on the other hand is a large piece of hardware — it’s about the size of a football field, and according to NASA it’s the second brightest object in the night sky. So why don’t we see it more often? Well, part of the reason is that you don’t know where to look. [Grady Hillhouse] set out to change that by building a what is basically a 2 degrees of freedom robot arm that will point you to where the ISS is at any given moment.

[Grady] uses a stepper motor for the azimuth, and a standard servo for the elevation, all powered by an Nucleo F401 development board, and an Adafruit motor shield and slip ring. The structure is made using some Erector set like parts from Actobotics.

He wrote the code from this open source project here. He’s currently cleaning up his code, and says he’ll be posting it up shortly. In the mean time, you can watch a video detailing the build in the video after the break. Or if you can’t wait, you can visit NASA’s web site to receive email or SMS messages on when the ISS is view-able in your hood.
