The BOX M3

Whats New, You may ask?

So whats new you may  ask, well there aint much but i did improve some aspects of theBOX M2 mainly in the hardware side of things. Now theBOX is a fully portable device no need of an wall outlet, and in order to house the new power delivery system i had to redesign the whole mainframe of theBOX. also added some quality of life improvements such better way to mount the nvme hat and other additions such as improved air vents , now then lets dive in deeper into theBOX M-3.

(Oh don't mind the different OS on the pictures,  I bricked my custom install while tinkering around , and theBOX was refusing to connect to wifi on boot so I wasn't able to reinstall my custom image and ended up installing the official raspberry pi os for a short amount of time)




The new and improved Chassis

so the new Chassis for theBOX is improved in some ways and just gotten worse in some , as for the improvements it got much more vents for air flow so the Active cooler would be able to pull more air to cool the pi when required, and it would  be able to house the new power supply solution, you guys can check out the 3D files over here (fun fact : everything was designed using tinkercad)

The new PSU

Yes you read it right! Now theBOX don't have to be tethered to wall anymore, now its more of a cyberdeck haha. You may ask whats the new psu?? well i just bought a powerbank and extracted all the components tweaked some aspects of it fit it inside the new chassis, well i initially wanted to go the Geekworm x1200 series USP hats and modify it so that the boards don't have to stack up each other but the modifying a powerbank option was much cheaper compared trial and erroring with the UPS hats, this does provide me with somewhere from 3 hrs to 10hrs of battery back up depending on the workload


What went wrong?

well things did not go as i planned for the M3 of theBOX mostly it was fine but after testing it out in the real world i faced quite a few challenges when it comes to ergonomics first of it was a bit longer compared to the M2 and heavier holding something like that in landscape was not fun when i had to hold it for longer time periods , also in the pursuit of adding more vents i kinda messed up the wall thickness so yea some of the walls were like 1 to 2mm thick not ideal if you wish to take it around places especially when those thin walls don't have any reinforcements.

So What's Next?

so far i have some things planned out for TheBOX M4 , mainly it'll be in portrait mode rather than being in landscape , maybe i can add some sort of accelerometer or gyro sensors to add kind of auto rotation feature like the ones on a smartphone (well i should note that down).
I also have plans to increase the battery Capacity from 10,000mah to 20,000mah and add the rest of the hardwares required for SDR and LoRa (maybe sub Ghz functionalities) well that would be fun to work with, well until then see yea

Building My Ultimate Cyberdeck: The Box  Introduction: Have you ever dreamed of having a completely self-contained, portable computer that you can use for anything, anywhere? I have, and that dream has led me to create "The Box m1," my personal project to build the ultimate DIY cyberdeck. This blog post will detail the initial stages of this exciting endeavor, from choosing the core components to overcoming early design challenges. The Brains of the Operation: The heart of any computer is its processing unit. For The Box m1, I chose the Raspberry Pi 5. While the Radxa Rock 5B was a strong contender, I ultimately opted for the Pi 5 due to its vast community support and robust official software ecosystem. This ensures access to a wealth of resources, troubleshooting assistance, and ongoing updates. At the time of starting this project, the Compute Module 5 (CM5) wasn't available, which further solidified the decision to use the readily available Pi 5. Navigating...

GNOME on Raspberry pi OS

 So this will be my guide to install GNOME on raspberry pi OS  #Step:1 Install Raspberry  Pi OS lite Install Raspberry Pi OS lite (64bit) Using Raspberry pi Imager on to your boot drive (SD card or nvme ssd), I recommend filling in the customization settings. This will allow you to pre-configure settings like the hostname, enable SSH, set up username and password and configure wifi details make sure that SSH is enabled #Step:2 BOOT Install your SD card or nvme ssd to the pi 5 and connect the power supply to boot into Raspberry pi OS lite #Step:3 Use SSH Since it is the lite version of pi OS it does not have a GUI or a desktop environment to make things easier we'll be using SSH to run commands and  install GNOME to pi OS lite if a monitor or other display source is connected then the IP address will be displayed there otherwise use software like Angry IP scanner or other IP scanner software to obtain the IP...

theBOX Software side

which os should be theBOX running? well since the brains of the system is raspberry pi5  the obvious choice would be Raspberry pi OS or Raspbian as it was called but theBOX uses a touch screen for all its navigation and Raspberry pi os was built up from the ground to be navigated with a keyboard and mouse which theBOX lacked while not docked (yep am planning to build a dock for it as well) The issue with raspberry pi os (Raspbian) Raspberry pi os uses PIXEL desktop environment by default which is light weight but no suitable for touch navigation  So I set out to find the best operating system to run on theBOX Raspberry pi has great software support for example for choice of operating system by default you can run Ubuntu, Kali, Parrot ,Alpin linux , Arch linux and many more without tinkering too much Attempt:1 Kali Linux My first thought was to just go with Kali since its the go to operating system for everyone who is interested in hacking or pen testing after Installing Kali o...
