Hackable media box based on the Raspberry Pi compute module: Five Ninjas Slice

Come and fiddle with our Linux-powered toy


Flash happy

I’ve mentioned the HDMI, audio and USB ports, but Slice also has an RJ45 for Ethernet, though only up to 100Mb/s. That’s the Pi origins showing through. There’s no Wi-Fi in the unit itself, but Five Ninjas is bundling a 2.4GHz 802.11n dongle. Power is provided by a 5V, 3A wall wart.

Can be bought with HDD supplied, but if you've a spare to hand...

Slice’s aforementioned remote is good. It uses Bluetooth (or something akin to it) which is easily paired to the base unit. The only disappointment is that the receiver – another wee dongle – isn’t built in, so that’s another USB port gone. Still, it’s very responsive and allows you to control the Slice without pointing at it. I could quite easily wander into the kitchen and, out of line of sight, start music playing.

However, the remote exposes the Slice’s key ‘flaw’, already hinted at by the software. This media centre is built almost entirely from off-the-shelf parts. The motherboard is custom, sure, but it’s essentially a glorified Raspberry Pi. Buy yourself a Raspberry Pi 2; install OpenElec; hook up an external HDD; buy the remote from Alibaba; and you have your own DIY Slice.

Slice skins

You won’t get the very nice metal casing or the fun lighting effects, of course, but the latter are more gimmicks than anything: cute but by no means essential to the device’s operation. If you stream all your media, you don’t even need the internal storage.

Five Ninjas is aware of this and, unlike so many other manufacturers, doesn’t pretend that there’s literally nothing like Slice on the market. There’s nothing here that, say, set-top boxes from Roku, Apple, Google or WD don’t do – other than the lighting effects and the support for a built-in HDD, of course.

Designed to be hacked as desired

They do it more cheaply too, and provide access to online services like Netflix and BBC iPlayer, but offer far, far less scope for messing about with the hardware as you see fit. Indeed, Five Ninjas is quite happy if you re-flash the 4GB storage with another OS and turn it back into a Raspberry Pi. It wants Slice to be considered as hackable as the first Apple TV was.

And I think that‘s why I like the Slice – and why I put ‘flaw’ in quote marks. You sense this is a media player built by unrepentant hardware and software tinkerers to put in their own living rooms and which they’ve decided to give everyone else a chance to own, too.

The Reg Verdict

Five Ninjas has come up with a tasty Pi-powered media playback machine based on open source software. The hardware’s done, but the software needs a little further work and lacks access to many of the streaming services a lot of potential users have grown accustomed to. This is never going to be a mass-market proposition, but if its open source credentials and internal accessibility appeals, it’s worth a look. ®

  • Prisons transcribe private phone calls with inmates using speech-to-text AI

    Plus: A drug designed by machine learning algorithms to treat liver disease reaches human clinical trials and more

    In brief Prisons around the US are installing AI speech-to-text models to automatically transcribe conversations with inmates during their phone calls.

    A series of contracts and emails from eight different states revealed how Verus, an AI application developed by LEO Technologies and based on a speech-to-text system offered by Amazon, was used to eavesdrop on prisoners’ phone calls.

    In a sales pitch, LEO’s CEO James Sexton told officials working for a jail in Cook County, Illinois, that one of its customers in Calhoun County, Alabama, uses the software to protect prisons from getting sued, according to an investigation by the Thomson Reuters Foundation.

    Another terrible launch, but DICE is already working on improvements

    The RPG Greetings, traveller, and welcome back to The Register Plays Games, our monthly gaming column. Since the last edition on New World, we hit level cap and the "endgame". Around this time, item duping exploits became rife and every attempt Amazon Games made to fix it just broke something else. The post-level 60 "watermark" system for gear drops is also infuriating and tedious, but not something we were able to address in the column. So bear these things in mind if you were ever tempted. On that note, it's time to look at another newly released shit show – Battlefield 2042.

    I wanted to love Battlefield 2042, I really did. After the bum note of the first-person shooter (FPS) franchise's return to Second World War theatres with Battlefield V (2018), I stupidly assumed the next entry from EA-owned Swedish developer DICE would be a return to form. I was wrong.

    The multiplayer military FPS market is dominated by two forces: Activision's Call of Duty (COD) series and EA's Battlefield. Fans of each franchise are loyal to the point of zealotry with little crossover between player bases. Here's where I stand: COD jumped the shark with Modern Warfare 2 in 2009. It's flip-flopped from WW2 to present-day combat and back again, tried sci-fi, and even the Battle Royale trend with the free-to-play Call of Duty: Warzone (2020), which has been thoroughly ruined by hackers and developer inaction.

  • American diplomats' iPhones reportedly compromised by NSO Group intrusion software

    Reuters claims nine State Department employees outside the US had their devices hacked

    The Apple iPhones of at least nine US State Department officials were compromised by an unidentified entity using NSO Group's Pegasus spyware, according to a report published Friday by Reuters.

    NSO Group in an email to The Register said it has blocked an unnamed customers' access to its system upon receiving an inquiry about the incident but has yet to confirm whether its software was involved.

    "Once the inquiry was received, and before any investigation under our compliance policy, we have decided to immediately terminate relevant customers’ access to the system, due to the severity of the allegations," an NSO spokesperson told The Register in an email. "To this point, we haven’t received any information nor the phone numbers, nor any indication that NSO’s tools were used in this case."
