Building A NAS That Really Looks Like A NAS

January 20, 2023 by 18 Comments

Building your own network attached storage (NAS) for personal use isn’t all that difficult. A single board computer, a hard disk and a power supply in an enclosure is all the hardware you need. Then, choose from one of several open source NAS software solutions and you’re up and running. [tobychui] decided to notch things up by designing a NAS that really looks like a NAS. It’s tailored to his specific requirements and looks like a professional product to boot. The design features dual 3.5 inch HDD bays, a small footprint, is low cost, compatible with a variety of single board computers, and can handle high data transfer speeds by using RAM and SD card for buffering.

Not only has he done a great job with the hardware design, but he’s also developed a companion software for the NAS. “ArozOS” is a web desktop operating system that provides full-fledged desktop experience within a browser. ArozOS has a great user interface and features a lot of networking, file, disk management and security functions. He has also developed a launcher application to enable over-the-air (OTA) software updates.

Assembling the device will need some planning and preparation, even though most of the hardware is off the shelf. You will need a SATA to USB 2.0 adapter, a SBC (Orange Pi Zero, Raspberry Pi 4, Orange Pi Zero 2, etc) , three buck converters — one each to provide 12 V to the two hard disks and a third to provide 5 V to the SBC. You’ll also need a 12 V / 6 A or 24 V / 3 A external power brick, or a USB-C 65 W GaN charger with a triggering module to set the desired voltage and current.

There is also one custom power distribution board which is essentially a carrier board to mount the buck converters and connectors for power and USB data. For the 3D prints, [tobychui] recommends printing at the highest resolution for a nice finish.

The off the shelf SATA to USB adapter will need to be taken apart before it can be fixed to the 3D printed SATA adapter plate and might pose the most challenge during construction, but the rest of the assembly is fairly straightforward. Once assembly is complete, [tobychui] walks you through installation of the ArozOZ software, mounting the drives and making them accessible over the network.

Have you got your data backup act in order ? If not, it’s still not too late to make it a new Year’s resolution. And if you need help figuring things out, check out New Year Habits – What Do You Do For Data Storage?

An Epic Quest To Build The Perfect Retro Handheld

November 26, 2019 by 15 Comments

It’s a good time to be a fan of classic video games. Most of us carry around a smartphone that’s more than capable of emulating pretty much everything from the 32-bit era on down, and if you want something a little more official, the big players like Sony and Nintendo have started putting out “retro” versions of their consoles. But even still, [Mangy_Dog] wasn’t satisfied. To get the portable emulation system of his dreams, he realized he’d have to design and build it himself.

The resulting system, which he calls the “Playdog Blackbone”, is without a doubt one of the most impressive DIY builds we’ve ever seen. While there are still some issues that he’s planning on addressing in a later version of the hardware, it wouldn’t be an exaggeration to say that there’s commercially available game systems that didn’t have half as much thought put into them as the Blackbone.

Which is, incidentally, how this whole thing got started. The original plan was to buy one of those cheap emulation handhelds, which invariably seem to come in the form of a PSP clone, and fit it with a Raspberry Pi. But [Mangy_Dog] quickly realized that not only were they too small to get everything he wanted inside, but they also felt terrible in the hand. Since he wanted the final product to be comfortable to play, his first step was to design the case and get feedback on it from other retro game enthusiasts.

After a few iterations, he arrived at the design we see today. Once he printed the case out on his SLA printer, he could move on with fitting all of his electronics inside. This takes the form of a custom PCB “motherboard” which an Orange Pi Zero Plus2 (sorry Raspberry fans) connects to. There’s actually a surprising amount of room inside the case, enough for niceties like dual speakers and a fan complete with ducting to keep the board cool.

Unsurprisingly, [Mangy_Dog] says a lot of people have been asking him if they can buy their own version of the Blackbone, and have suggested he do a crowdfunding campaign to kick off mass production. While he’s looking at the possibility of resin or injection molding the case so he can produce a few more copies, on the whole, his attention has moved on to new projects. Which frankly, we can’t wait to see.

If you’re interested in slightly more modern games, we’ve seen a number of handhelds based on “trimmed” Nintendo Wii’s which you might be interested in. While they might not have the sleek external lines of the Blackbone, the work that goes into the electronics is nothing short of inspirational.

Golf Practice Made Easy With Robotics

September 20, 2018 by 11 Comments

When you think of sports, you usually think of something that takes a lot of physical effort. Golf is a bit different. Sure, you can get some walking in if you don’t take a cart. But mostly golfing is about coordination and skill and less about physical exertion. Until you want to practice driving. You hit a bucket of balls and then you have to go walk around and pick them up. Unless you have help, of course. In particular, you can delegate the task to a robot.

The robot that [webzuweb] built looks a little like a plywood robot vacuum. However, instead of suction, it uses some plywood disks to lift the balls and deposit them in a hopper. The electronics consist of an Arduino and an Orange Pi Lite. A GPS tells the robot where it is and it develops a search pattern based on its location.

Portable Guitar Amp – Is That A Linux In Your Pocket?

March 5, 2018 by 18 Comments

When it comes to music production and audio engineering, Linux isn’t the most common choice. This isn’t for lack of decent tools or other typical open source usability issues: Ardour as a highly capable, feature-rich digital audio workstation, the JACK Audio Connection Kit for powerful audio routing, and distributions like Ubuntu Studio packing all the essentials nicely together, offer a great starting point as home recording setup. To add variation to your guitar or bass arrangement on top of that, guitarix is a virtual amp that has a wide selection of standard guitar effects. So when [Arnout] felt that his actual guitar amp’s features were too limiting, he decided to build himself a portable, Linux-based amp.

[Arnout] built the amp around an Orange Pi Zero with an expansion board providing USB ports and an audio-out connector, and powers it with a regular USB power bank to ensure easy portability. A cheap USB audio interface compensates the lacking audio-in option, and his wireless headphones avoid too much cable chaos while playing. The amp could theoretically be controlled via a MIDI pedalboard, but [Arnout] chose to use guitarix’s JSON API via its built-in Python web interface instead. With the Orange Pi set up as WiFi hotspot, he can then use his mobile phone to change the effect settings.

One major shortcoming of software-based audio processing is signal latency, and depending on your ear, even a few milliseconds can be disturbingly noticeable. To keep the latency at a minimum, [Arnout] chose to set up his Orange Pi to use the Linux real-time kernel. Others have chosen a more low-level approach in the past, and it is safe to assume that this won’t be the last time someone connects a single-board computer to an instrument. We surely hope so at least.

$10 Orange Pi 2G-IoT Released To Compete With Pi Zero W

April 11, 2017 by 76 Comments

A new single-board computer by Orange Pi has popped up for sale on AliExpress. The Orange Pi 2G-IoT is designed to compete with the Raspberry Pi Zero, and if specs are anything to go by they have done a nice job.

There are a lot of options for extra small single board computers these days and there’s a growing list at the lowest price points. Let’s call it the sub-$20 cost range (to quell the argument of shipping fees). We have seen C.H.I.P., the Raspberry Pi Foundation released the Pi Zero W (an update to the Zero line that included WiFi and Bluetooth), the already available Orange Pi Zero (which was featured in a project on Monday), and now add to that list the unfortunately named Orange Pi 2G-IoT.

The 2g-IoT is sporting an ARM Cortex-A5 32bit clocked at 1GHz with 256MB DDR2 RAM. It’s nice to see 500 MB of on-board NAND to go along with an SD card slot for larger storage. It also has a CSI camera connector, WiFi, Bluetooth, an FM Radio and GSM/GPRS with a sim card slot on the bottom. It is pin compatible with Raspberry Pi’s almost standardized GPIO layout.

All this for $10 is quite impressive to say the least, especially the addition of GSM/GPRS. Will it kill Raspberry Pi Zero W sales? We think not. While the Orange Pi’s are great little computers, they don’t have the community support that is afforded to Raspberry Pi products making for less support online when you run into a problem. That’s if you can even get the thing running in the first place. The Orange Pi’s website has not yet been updated to reflect the new release. However if you are interested in getting one for yourself right now, head over to your favorite Chinese electronics supplier.

Orange Pi Releases Two Boards

November 7, 2016 by 134 Comments

A few years ago, someone figured out small, cheap ARM Linux boards are really, really useful, extremely popular, sell very well, blink LEDs, and are able to open the doors of engineering and computer science to everyone. There is one giant manufacturer of these cheap ARM Linux boards whose mere mention guarantees us a few thousand extra clicks on this article. There are other manufacturers of these boards, though, and there is no benevolent monopoly; the smaller manufacturers of these boards should bring new features and better specs to the ARM Linux board ecosystem. A drop of water in a tide that lifts all boats. Something like that.

This week, Orange Pi, not the largest manufacturer of these small ARM Linux boards, has released two new boards. The Orange Pi Zero is an inexpensive, quad-core ARM Cortex A7 Linux board with 256 MB or 512 MB of RAM. The Orange Pi PC 2 is the slightly pricier quad-core ARM Cortex-A53 board with 1 GB of RAM and a layout that can only be described as cattywampus. We all know where the inspiration for these boards came from. The price for these boards, less shipping, is $6.99 USD and $19.98 USD, respectively.

The Orange Pi Zero uses the Allwinner H2 SoC, and courageously does not use the standard 40-pin header of another very popular line of single board computers, although the 26-pin bank of pins is compatible with the first version of the board you’re thinking about. Also on board the Orange Pi Zero is WiFi provided by an XR819 chipset, Ethernet, a Mali400MP2 GPU, USB 2.0, a microSD card slot, and a pin header for headphones, mic, TV out, and two more USB ports.

The significantly more powerful Orange Pi PC 2 sports a quad-core ARM Cortex-A53 SoC coupled to 1 GB of RAM. USB OTG, a trio of USB 2.0 ports, Ethernet, camera interface, and HDMI round out the rest of the board.

Both of Orange Pi’s recent offerings are Allwinner boards. This family of SoCs have famously terrible support in Linux, and the last Allwinner Cortex-A53, that we couldn’t really review, was terrible. Although the Orange Pi Zero and Orange Pi PC 2 are new boards and surely software is still being written, history indicates the patches written for this SoC will not be sent upstream, and these boards will be frozen in time.

If you’re looking for a cheap Linux board with a WiFi chipset that might work, The Orange Pi Zero is very interesting. The Orange Pi PC 2 does have slightly impressive specs for the price. When you buy a single board, though, you’re buying into a community dedicated to improving Linux support on the board. From what I’ve seen, that support probably won’t be coming but I will be happy to be proven wrong.
