You can build a sci-fi-looking Linux computer for around $100. 💻🔧 A Raspberry Pi Zero 2 W costs roughly $15–20, and it can become the heart of a portable computer called a cyberdeck. The basic setup is surprisingly simple. A Raspberry Pi handles the computing, a small HDMI display provides the screen, and a wireless keyboard with a built-in touchpad handles navigation. Add a power bank, microSD card, and a case, and you can build a functional cyberdeck for roughly $80–110, depending on the components you choose. But the best part is the freedom to customize it. You can build one to learn Linux, practice programming, connect electronics, run lightweight tools, or simply create a computer that works exactly the way you want. Some people turn them into rugged field computers. Others make tiny handheld versions. The hardware doesn’t need to be powerful to be useful. And building one forces you to understand how computers, power, displays, storage, and software actually work togethe...
