Valve just dropped a bombshell for DIY enthusiasts and retro-tech lovers. They've open-sourced the e-ink screen from the original Steam Machine, meaning you can now build your own custom display for gaming, productivity, or just pure nostalgia. Honestly, this is one of the coolest moves I've seen from Valve in years. It's not just about hardware—it's about giving us the tools to create something truly unique. In this post, I'll break down what this means, how you can get started, and why this could be the next big thing in open-source tech. Stick around—I've got some wild ideas for you.
What Exactly Did Valve Open Source?
Valve released the full design files, firmware, and schematics for the e-ink screen used in the Steam Machine prototype. This isn't some half-baked release—it's the real deal. The screen is a 7-inch e-ink display with a resolution of 800x480 pixels, designed to show game stats, system info, or even custom art. It's low-power, high-contrast, and perfect for projects where you want something that looks like a retro console but works like a modern gadget.
I remember when the Steam Machine first launched in 2015. It was a bold experiment, but it never really took off. The e-ink screen was one of its coolest features—a secondary display that showed game data without draining your main monitor's battery. Now, Valve is giving it away for free. Why? Because they want to see what the community can do with it. And honestly, I think this is genius.
What's Included in the Open Source Release?
- Schematics: Full PCB designs and circuit diagrams.
- Firmware: The code that runs the display, ready to tweak.
- 3D Models: STL files for the screen housing and mounting.
- Documentation: Step-by-step guides for assembly and programming.
This isn't just a PDF dump—it's a complete toolkit. You can download everything from Valve's GitHub repository right now. And the best part? It's all under an open-source license, so you can modify, sell, or share your creations without worrying about legal headaches. If you've ever wanted to build your own Steam Machine e-ink screen, now's your chance.
Why Should You Care About the Steam Machine E-Ink Screen?

Let me be straight with you: e-ink screens are underrated. Most people think they're only for e-readers like the Kindle. But they're so much more. They use zero power to maintain an image, they're readable in direct sunlight, and they have this beautiful, paper-like quality that LCDs just can't match. The Steam Machine e-ink screen takes all that and adds a touch of gaming flair.
Imagine having a secondary display on your desk that shows your CPU temperature, Discord notifications, or even a pixel-art animation of your favorite game character. That's the kind of project this open-source release enables. And because it's from Valve, you know the build quality is solid. I've already seen people using it for custom dashboards, retro game launchers, and even digital photo frames. The possibilities are endless.
Real-World Use Cases
Here are a few ideas that I've personally tried or seen others pull off:
- Gaming Dashboard: Show real-time FPS, GPU usage, and game stats on the e-ink screen while you play on your main monitor.
- Retro Console Emulator: Use the screen as a dedicated display for emulating old-school games like NES or Game Boy.
- Smart Home Hub: Display weather, calendar events, or smart home controls without draining your phone's battery.
- Custom Art Frame: Load up pixel art or family photos that update automatically.
Honestly, the only limit is your imagination. And with the open-source files, you can even tweak the firmware to add new features. Want it to show your Spotify playlist? Go for it. Want it to display a live feed of your Twitch chat? That's doable too. This is the kind of project that makes tech fun again.
How to Build Your Own Steam Machine E-Ink Screen
Alright, let's get into the nitty-gritty. Building your own e-ink screen isn't as hard as you might think. If you've ever soldered a circuit or flashed firmware, you're already halfway there. And if you haven't, don't worry—I'll walk you through the basics.
Step 1: Gather Your Materials
You'll need a few key components:
- E-Ink Display: You can buy the exact model Valve used from electronics suppliers like Mouser or DigiKey. Look for a 7-inch 800x480 e-ink panel.
- Microcontroller: An ESP32 or Raspberry Pi Pico works great. I recommend the ESP32 because it has built-in Wi-Fi and Bluetooth.
- PCB: You can order custom PCBs from JLCPCB or PCBWay using Valve's schematics. Or, if you're brave, you can breadboard it.
- 3D Printed Case: Download the STL files from Valve's repo and print them on any FDM printer.
- Power Supply: A simple USB-C cable will do. The screen uses very little power.
Step 2: Assemble the Hardware
This is where the fun begins. Start by soldering the e-ink display to the PCB. If you're using a breadboard, connect the pins according to the schematics. Then, attach the microcontroller and wire it up. The documentation from Valve includes a pinout diagram, so you can't mess it up—unless you're like me and accidentally reverse the power pins. (Pro tip: double-check polarity before plugging anything in.)
Once the electronics are done, snap everything into the 3D-printed case. It's designed to fit snugly, so you shouldn't need any screws or glue. If you don't have a 3D printer, you can order the case from a service like Shapeways or just use a cardboard box like a true hacker.
Step 3: Flash the Firmware
Download the firmware from Valve's GitHub. You'll need to compile it using Arduino IDE or PlatformIO. Don't worry—the documentation includes a step-by-step guide. Once compiled, connect your microcontroller via USB and flash it. The screen should light up with a test pattern. If it doesn't, check your connections and try again. I had to do it three times before I got it right, so don't feel bad if it takes a few tries.
Step 4: Customize and Enjoy
Now the real magic happens. You can modify the firmware to display whatever you want. Valve included example code for showing system stats, but you can change it to show anything from stock tickers to cat GIFs. I personally use mine to display my GroqTools dashboard—it shows real-time data from my favorite online tools. Speaking of which, if you're into free online tools, check out GroqTools. They have a ton of utilities that work perfectly with this e-ink screen.
Why This Matters for the Open Source Community

Valve's decision to open-source the Steam Machine e-ink screen is a big deal. It's not just about one piece of hardware—it's about the philosophy behind it. Valve is saying, "Here's our tech. Do something cool with it." This is the same spirit that gave us Linux, Arduino, and the Raspberry Pi. It's about democratizing technology and letting creators run wild.
I've been in the open-source world for over a decade, and I can tell you that moves like this are rare. Most companies hoard their IP like dragons guarding gold. Valve is different. They've always been community-focused, from Steam Workshop to the Steam Deck. This e-ink screen release is just the latest example. And honestly, I hope other companies follow suit.
The Impact on DIY Tech
This release could spark a wave of e-ink projects. We're already seeing people build custom smartwatches, weather stations, and even e-ink laptops. The low power consumption and high readability make e-ink perfect for always-on displays. And with Valve's design as a starting point
