Building Your Dream Cyberdeck: Beginner Tips & Lessons Learned —a collection of notes from my first proper cyberdeck build. Full tutorial otw
cy·ber·deck /ˈsaɪ.bɚ.dɛk/
a portable, often custom-built computing system centered around a single-board computer (SBC), designed for modularity, experimentation, and personal control over hardware and software. Prioritizes user-defined purpose over mass-market design constraints.

Like many of you, cyberdecks have been all over my Instagram feed lately. As someone who is studying computer science and likes to dabble in ECE, the idea of a pocket-sized calendar device was the perfect excuse to finish this personal project that I’ve been wanting to build for a while.
The first decision you will probably make is selecting your SBC, or single board computer. My main advice is the following: don't listen to the people who say that Raspberry Pi is the only way to go; the best SBC is usually the one you already have access to, especially for your first build. I currently have an abundance of Orange Pi One Plus boards, and for a simple system like this, it works pretty well*
One assumption I had going in was that any real hardware project requires soldering, and I was prepared to try to brush up on my rusty soldering skills. So far, I haven’t touched a soldering iron. If you buy/already have a board with pre-soldered GPIO headers, USB peripherals + plug-and-play displays will cover a surprising amount of ground. Soldering is a skill worth learning eventually, but it is definitely not the barrier to entry.
The operating system turned out to be the most involved part of the project. One nice thing about SBCs that boot from removable microSD storage is that the OS becomes completely modular: instead of repartitioning or reflashing a drive every time I want to evaluate a distribution, I keep multiple preconfigured cards and swap them. Each card is effectively a self-contained system image. I ultimately settled on Armbian*
On the operating system side, I started building my own mermaid-inspired Linux distro, but I realised pretty quickly that if I wanted to finish in 1/2 weeks, that was probably not the most viable idea. That, however, does not mean that MermaidOS would be off the table in the future.

The installation itself was straightforward. I downloaded the Armbian image on my MacBook Pro, inserted a microSD card via an SD adapter into the built-in card reader, and flashed it with Balena Etcher, which handles image writing and verification in one pass. The genuinely difficult part was mechanical, not digital — I spent close to thirty minutes trying to extract the microSD card from the adapter afterward because I had pushed it in too far. The spring mechanism only needs a gentle press to engage and release. File that under lessons you only learn once.
For the display, I went through my old project boxes and found a compatible Arduino LCD from a previous build. It’s worth auditing your existing parts before placing new orders; nearly all of the components for this project came from hardware I already owned.
Power is handled by a standard USB power bank, which is by far the safest and best approach for powering a cyberdeck. For anyone concerned about bulk or aesthetics, plenty of cyberdeck designs hide the bank inside the enclosure with an internal compartment or sliding drawer.
At this point, the software is running, and the electronics are mostly sorted. What remains is designing and building the enclosure. I’m excited to share the final build as well as a full tutorial coming soon!
*Orange Pi One Plus: an inexpensive board with an Allwinner H6 with four ARM Cortex-A53 cores, 1GB of RAM, and Gigabit Ethernet. The notable omission is onboard Wi-Fi, which matters less than people assume(a USB Wi-Fi adapter costs a few dollars and works on most Linux distros). I will say, if you are building something more complicated, which I would not recommend for a first build, a Raspberry Pi 4 with 2–4GB of RAM would be near the top of my list purely on the strength of its documentation and community ecosystem.
*a Debian-based distribution built specifically for ARM single-board computers. It’s lightweight, actively maintained, and ships proper kernel and bootloader support for boards like the Orange Pi that mainline distributions often handle poorly. Since this build doesn’t need a heavy desktop environment, a lean distribution that boots fast and idles low made the most sense.
