This novel cyberdeck integrates with the Steamdeck and other compatible USB-C mobile processing devices, to give the user portable access to a full-sized keyboard, mouse, and additional USB devices. The CPC Cyber Cepter integrates a pico-projector as a supplemental display for on-the-go gaming and political resistance.

Technically compatible with Wireless VR Display, via ALVR and the Oculus Quest, though performance is not worth writing about.

CPC-Cyber Cepter is a Comprehensive Peripheral Cluster on-a-stick.
It provides any connected device with a suite of peripherals, like mouse, keyboard, multiple LAN options, wifi-scanner, and external display via pico projector, VR HMD, or traditional monitor.

Since it doesn't have a dedicated computational core, I consider it more of a Cyberdock.


CPC-Cepter is fully wireless and supports a solid connection to Steam-VR via ALVR streaming.

  • VR Integration

    VR Support for Linux is still in it's infancy. I think If I'd set up a Windows partition on my steam deck, this would work much better, but it still works.

    Using ALVR, side-loaded onto my Quest, and installed on the Steam Deck in Desktop mode (, it pretty seamlessly connects and renders a VR environment.

    I'd like to try SumulaVR ( or XrDesktop (, but I haven't had the opportunity yet.

    Here it is, in it's glory!
    The Comprehensive Peripheral Cluster, Cepter

    Check out that CAM lever. It's a Keyblade from Kinddom Hearts. I made that!

    This would look better if I had a proper screen, but I wanted to show off my water-color maps of Elden Ring.

  • Steamdeck Device Mount

    Sp4m09/21/2022 at 03:36 0 comments

    I'd tried a handful of SteamDeck mounting kits, and the DeckMate (even the version I printed at home) stands out above the rest.

    I made my own mount that would connect to the ring-mount, and featured VESA-compatible prongs that I could use for additional accessories, if desired. 

    I printed the support "beams" of the deckmount with a rough texture (called fuzzy skin) in PRUSA Slicer, so it would have a little more friction when clamped onto the rings, and that (plus some rubber washers) seems to hold quite nicely.

  • Ring-Mount Keyboard

    Sp4m09/21/2022 at 03:30 0 comments

    Finally, I needed a way to connect my keyboard and device, so they could be adjusted if necessary. 

    Why do I need to adjust them? Because I like to make things difficult.

    The E-Waste Gods had graced me with a Gen-1 Apple Magic Keyboard. I made these parts to securely affix it to the hilt, using Cam-levered 5mm "go-pro" compatible bolts. It took a lot of trial and error to get the mounts to fit the keyboard properly, but it works just as well as I'd hoped.

  • Projector Box (Pommel)

    Sp4m09/21/2022 at 03:23 0 comments

    I needed a pommel of some sort to help keep the weight balanced. 

    Initially, I just made a storage box that would fit my laptop charger, or extra cables/tools. 

    This was basically perfect, and painfully over-engineered. The "lid" of the box has a slot that lets the box seat easily, without needing maker-beam to attach to the far side of the box. This was good, but I was ahead of schedule, and I was going to VEGAS for a hacker convention (I HATE VEGAS SO MUCH). I had to kick it up a notch.

    BAM! This little box houses a "PIQO" projector that I'd kickstarted a few years back. The projector is mounted inside a free-spinning cylinder that allows for Y-axis adjustment, while all necessary controls remain accessible. The projector also has its own batter, good for about 2 hours, though it can also be powered from the connected powerbank. 

  • Constructing the Hilt

    Sp4m09/21/2022 at 03:09 0 comments

    I apologize. I'd written a detailed and hilarious story about all the work I went through to build this hilt, and how I even considered building in an umbrella holder, but then my network connection pooped, and I lost my work. So this is what you get.

    Starting from the awesome Katana design made by Grzywa on thingiverse, I traced over the mesh, and made my own copy that more specifically met my requirements.

    I cut out material to allow the makerbeam (1 cm extruded aluminum bars) to run through the middle, added a cable channel, and made adjustments to the model to facilitate vertical, supportless printing.

    I built in a cut-out, so I could add this dangerous looking wi-fi antenna that came with my motherboard. (It was too easy to get this on a plane initially).

    This is the most substantial part of the build, and I ended up printing quite a few prototypes before I was satisfied. 

  • The Big Box

    Sp4m09/21/2022 at 02:25 0 comments

    The first thing I had to design was the "Big Box." Initially I made a triangular container, inspired by an awesome Lego Space ship... but it felt both too large, and was too small to house both the power bank and the hub :^(. So for Round 2, I went with a rounded square, and I thought that did the job just right. I sized it as small as I could while still fitting the power bank, and made slots for the hub as well. The whole thing is designed to be printed without supports, because supports are my nemesis.

    I apologize for the terrible angle of this (and surely the rest) of the captures. I barely know how to use Fusion 360.

  • The Practical Use Case

    Sp4m09/21/2022 at 00:21 0 comments

    The Comprehensive Peripheral Cluster was born out of a need to connect a suite of dongled-devices to my various simpler computational slabs.

    My Smartphone, Surface, Tablet and Steamdeck are all compatible with keyboard, mouse, and external displays, provided I've got a way to connect and transport them.

    Hence, the Cyberdock. I say Dock, since the computational power is externally sourced.

  • Cam Lever 2.0

    Sp4m09/21/2022 at 00:15 0 comments

    The first version of my Cam Lever wasn't large enough, or strong enough.

    However, sizing it up was easy, and with the help of some print-on supports, the whole thing prints in one piece, without supports. Hooray!

    I also made a variation that uses a keyblade handle instead of a lever.

  • Building a Cam Lever

    Sp4m09/08/2022 at 13:52 0 comments

    This is my first post, which is weird, because my project is almost done. I have some back-filling to do.

    I think a cam lever is a convenient way to attach and tighten the various bits and bobs to my ring mount, but the "real" ones are expensive. Even worse (or better?!) I can't find one for download online, free or paid.

    This (and the summer heat) smells like an opportunity to make the world better!

    Time for CAD.

    Figure 1. I placed the cam-shaft hole too-far off-center. Can you tell this is my first time?

    Figure 2. I'm self-taught in Fusion360, so there are always weird things that I don't understand. For example, I can't select the circular sketch here. No idea why.  

    Figure 3. Version 1 of the Cam Lever is ready for printing! I'll have to try it out tonight.

    This process took me about 2 1/2 hours.
