At this point, we’ve seen more Raspberry Pi Network Attached Storage (NAS) builds than we can possibly count. The platform was never a particularly ideal choice for this task due to the fact it could only connect to drives over USB, but it was cheap and easy to work with, so folks made the best of it. But that all changed once the Compute Module 4 introduced PCIe support to the Raspberry Pi ecosystem.
If this impressive NAS built by [mebs] represents the shape of things to come, we’re more than a little excited. On the outside, with its 3D printed case and integrated OLED display to show system status, it might look like plenty of builds that came before it. But pop the top of this cyberpunk-styled server, and you realize just how much work went into it.
At the heart of this NAS is a purpose-built carrier board that [mebs] designed based on the KiCad files the Raspberry Pi Foundation released for their official CM4 IO Board. While not much larger than the CM4 itself, the NAS board breaks out the board’s PCIe, Ethernet, HDMI, and USB. There’s also a header for I2C, used primarily for the OLED display but naturally expandable to additional sensors or devices, and nine GPIO pins for good measure.
Of course, that alone doesn’t make a NAS. Into that PCIe port goes a four channel SATA controller card, which in turn is connected to the hard disk drives that are nestled into their respective nodes of the printed case. A central fan blows over the electronics at the core, and thanks to clever design and a few cardboard seals, pulls air over the drives by way of intake vents printed into the sides.
If you’ve got a personal website that needs hosting or a few hundred gigabytes of files that could use a centralized storage location, the Raspberry Pi’s small size and extreme energy efficiency make it a compelling server choice compared to that curbside Pentium 4 box you’ve been trying to find a home for. All you need is something to put in.
Of course there’s no shortage of Pi case designs ready to be extruded from your 3D printer, but we recently found ourselves particularly taken with this unique one designed by [Ken Segler]. It’s not only small and sleek with a dash of futuristic flair, but it includes a front-mounted two inch 240 x 320 IPS display that connects to the Pi over SPI. At the minimum that gives you a way to see all those beautiful boot messages on startup, but with a little code, it could provide you with various system statics and status messages at a glance.
While the LCD is clearly the star of the show here, the case also has a few other nice features that make it worthy of your consideration. The magnetically attached fan filter on the the top, for one. The stacked layout that puts the Pi directly above the SSD also makes for a relatively compact final product.
One thing to note though is that [Ken] is using Power-over-Ethernet, meaning there’s no spot for a dedicated power jack on the case. It’s an easy enough feature to add into your own build, but naturally not everyone’s network is suitably equipped. In that case, beyond the normal annoyances of editing STL files, it shouldn’t be too much trouble to add one in without having to literally hack your way through the printed plastic.
The Logitech SqueezeBox was a device you hooked up to your stereo so you could stream music from a Network Attached Storage (NAS) box or your desktop computer over the network. That might not sound very exciting now, but when [Aaron Ciuffo] bought it back in 2006, it was a pretty big deal. The little gadget has been chugging all these years, but the cracks are starting to form. Before it finally heads to that great electronics recycling center in the sky, he’s decided to start work on its replacement.
Thanks to the Raspberry Pi, building a little device to stream digital audio from a NAS is easy these days. But a Pi hooked up to a USB speaker isn’t necessarily a great fit for the living room. [Aaron] didn’t necessarily want his replacement player to actually look like the SqueezeBox, but he wanted it to be presentable. While most of us probably would have tried to make something that looked like a traditional piece of audio gear, he took his design is a somewhat more homey direction.
The Raspberry Pi 4 and HiFiBerry DAC+ Pro live inside of a wooden laser cut case that [Aaron] designed with OpenSCAD. We generally associate this tool with 3D printing, but here he’s exporting each individual panel as an SVG file so they can be cut out. We especially like that he took the time to add all of the internal components to the render so he could be sure everything fit before bringing the design into the corporeal world.
While the case was definitely a step in the right direction, [Aaron] wasn’t done yet. He added a WaveShare e-Paper 5.83″ display and mounted it in a picture frame. Software he’s written for the Raspberry Pi shows the album information and cover art on the display while the music is playing, and the current time and weather forecast when it’s idle. He’s written the software to plug into Logitech’s media player back-end to retain compatibility with the not-quite-dead-yet SqueezeBox, but we imagine the code could be adapted to whatever digital media scheme you’re using.
Projects that turn the Raspberry Pi into a low-cost Network Attached Storage (NAS) solution are very common; all you need is the right software, the Pi itself, and some USB storage devices. But unless you particularly like the “Medusa” look, with loose cables running all over the place, you’ll probably want to put the hardware into a suitable enclosure. Unfortunately, that’s where the somewhat unusual layout of the Pi can make things tricky.
Which is why [AraymBox] came up with this unique “capsule” enclosure for the Raspberry Pi and two USB-attached hard drives. Every effort has been made to keep the outside of this design as clean and streamlined as possible. The asymmetrical loops of wires that we so often see on other projects are gone, with everything been brought inside thanks to some clever wiring. This enclosure looks like a professional product, and if you’re willing to put in the effort, you can have one to call your own.
The good news is that the 3D printed enclosure only has four parts, albeit rather large ones, and none of which require support material. So it should be an easy print even on a relatively low-end machine. Of course, you’re not going to get that futuristic metallic look without a little work. You’ll need to do a considerable amount of sanding, filling, and paint work to get that kind of a surface finish. Then again, that rough “just printed” look has a certain cyberpunk appeal to it as well.
But the printed enclosure is only half the battle. Inside, [AraymBox] has soldered the USB to SATA adapter cables directly to the Raspberry Pi to keep things tight and compact. A micro USB breakout board was then used to add a power connector on the back of the device where the Ethernet and USB ports are, solving the issue of having one lonely USB cable coming out of the side of the case.
Back in 2018, [Paul-Louis Ageneau] created a 3D printed network-attached storage (NAS) enclosure for his Raspberry Pi. The design worked well, the Internet liked it when he posted the details on his blog, and all was right with the world. But of course, such glories are fleeting. Two years later that design needs updating, and thanks to the parametric nature of OpenSCAD, he’s been able to refresh his design for another tour of duty.
In our book, this is as much a cautionary tale as it is a success story. On one hand, it’s a testament to the power of CAD and desktop 3D printing. That a design can be tweaked and reproduced down the line with only minimal hassle is great for folks like us. But it’s also a shame that he didn’t get more than two years before some of the parts he used in the original NAS became unobtainium.
The main issue was that the integrated USB hub he used for the first version is no longer available, so the design had to be modified to accept a similar board. Unfortunately, the new hub is quite a bit wider than the old one. Resizing the entire case isn’t really an option since the Pi has to slide into it, so the hub now bumps out a bit on one side. He’s added a printable cover that cleans it up a bit, but the asymmetrical look might be a problem for some. While fiddling with the design, he also changed around the cooling setup so a larger fan could be mounted; now that the Raspberry Pi 4 is out, it can use all the cooling help it can get.
2020 is a year of reflection and avoiding regret, and one of the biggest practices we all know we should do better is back up our data. Inevitably there will be a corruption or accident, and we mourn the loss of some valuable data and vow to never let it happen again, and then promptly forget about good data retention practices.
I believe life is about acquiring memories, so it makes sense to me to try to archive and store those memories so that I can reflect on them later, but data storage and management is a huge pain. There’s got to be a better way (cue black and white video of clumsy person throwing up arms in disgust).
Nice Cloud You Have There; Shame if Something Happened to It
The teens of the century saw a huge shift towards cloud storage. The advantages of instantly backing up files and using the cloud as the primary storage for all your devices is appealing. It’s now easier to transfer files via the cloud than with a cable. With Google Docs and WordPress we have our most important documents and writing stored as database blobs on someone else’s servers. Facebook and Google and Flickr record all of our memories as photo albums. Unlimited storage is common, and indexing is so good that we can find photos with a vague description of their contents.
With the risk of data leaks and privacy violations occurring daily, it’s also safe to say that some of your files should probably not be stored in the cloud in the first place. So, how do we do it well, and how do we get in the habit of doing it regularly?
It’s safe to say that most of us have at least one Raspberry Pi hanging from a USB cable someplace, silently hammering away at some unglamorous task that you’d rather not do on a “real” computer. With as cheap as they are, it’s not like there’s a big concern about where it sets up shop. But if you’re like [Jeremy S. Cook] and want your $35 Linux computer to be a permanent member of the family, then his tips on turning an old PC into a gloriously overkill Pi NAS may be of interest.
The main component [Jeremy] salvages from the old Lenovo desktop PC is, obviously, the case itself. Stripped of its original components, the case gives him plenty of room to mount the Pi as well as a couple of hard drives and a powered USB hub. To prevent the bottom of the Raspberry Pi from shorting out against the metal computer case, he designed and 3D printed a mount for it. Everything else is held down with hook and loop fastener, making it quick and easy to move things around and make adjustments.
While it might not be strictly necessary, [Jeremy] also took the time to salvage the computer’s old heatsink. Being far too large to fit on the Pi as-is, he ran a line down the back of it with his mill and snapped it in half. He uses a bit of thermal tape to hold the bisected heatsink onto the Pi’s SoC, with a couple pieces of electrical tape to make sure it doesn’t short out on anything.
