Raspberry Pi & MediaPi Case

Possibly the best known of the Mini-PCs, the Raspberry Pi has one huge advantage. It is very well supported. However, there are two large disadvantages, IMO.

  1. 1 GB of memory seems insufficient even though the processor has four cores and has graphics acceleration. This limits this Mini-PC’s performance.
  2. Any Pi build seems to end up with a spaghetti of leads.

1 GB of memory seems insufficient even though the processor has four cores and has graphics acceleration. This limits this Mini-PC’s performance.Any Pi build seems to end up with a spaghetti of leads. (OK, my MediPi could be tidier!)

Then along came the Media Pi box. No need for a USB hub and all the leads are neatly contained within a cleverly built box. I bought one designed for the Pi 1 but installed a Pi 2 so the remote does not work, but that was half expected. There is now a newer box for the Pi 2 which, hopefully, overcomes this.

So, if you like the Pi or just want a tidy Kodi setup and don’t mind it being a bit larger than most of the current Mini-PCs, maybe the Media Pi box is for you. It is shown here running with a 2TB 2.5inch spinner, all tidily enclosed within the box, and a tiny WiFi keyboard.

One tip that wasn’t obvious to me. Use a 32GB class 10 or faster micro SD. Build your Pi using Noobs and select both Raspbian and one of the Kodi implementations and you can run both operating systems. Just select which one at start up. You should find that any problems that you hit will be easy to solve in the large Pi community.

However, if all you want to run is Kodi, a smaller and much cheaper alternative is one of the little streaming Android boxes. You just need to add a powered external hard drive and it will play all of your media through your HDMI TV.

The Mini-PC Explosion

16l-boxA new genre, the Mini-PC is rising in importance in the market place. Current machines are supplied with Windows 10, usually installed on an internal eMMC solid state drive. Some can be dual booted with Android but none are supplied with Linux installed. Neither does the Linux community seem to support this segment of the market, yet.

The Mini-PC is based on either the Intel Bay Trail or Cherry Trail chip set, and the so called Atom processors. Intel seem to be using the Atom name to cover a wide range of CPUs aimed at the battery efficient Android market.

Some of the earlier Bay Trail CPU/chip set Mini-PCs are still on the market, at around £70 and provide excellent value for money, IMO. The newer Cherry Trail CPU/chip set Mini-PCs seem to be aimed at the media centre market.

Currently, the top of the range is the Intel Atom x7-Z8750 Processor that can run up to 2.56 GHz. Launched Q1’16, it will support 4GB RAM. The earlier CPUs will only address 2GB and their burst frequencies are lower but most seem very capable CPUs. You pay your money, up to £150 at present, and take your choice. My current system is based on a Quad Core x5-Z8300 running at 1.45Ghz with a burst frequency of 1.84Ghz and plays HD video very well. No, it is not a gaming machine, but does everything that I throw at it very well, using Xubuntu.

The Sumvision Cyclone Mini Desktop

Unless you are a ‘gamer’, why do you still need a desktop PC? Maybe for you, a Tablet or a Laptop will suffice, but for me, I want a full size keyboard and a large screen and do not want to be plugging those in and out of a laptop.

However, desktop PCs take up a lot of real estate, and watts. As a consequence, I’ve been examining other options such as an:16l-box

  • Android box – quiet, runs cool, small but limited in its functions.
  • Raspberry Pi2 – quiet, runs cool, and almost does the job, but wont quite do all I want to do. Raspian, IMO, is a very sound solid operating system though.

My third attempt is with a mini-PC, in the guise of a Sumvision tiny box. It is called a “Sumvision® Cyclone Mini Micro Small Multi Media Desktop PC 2 Windows 10 Full 4K HD H.265 Smart TV Box Cherry Trail Intel Quad Core x5-Z8300 1.84Ghz 2G”.


Gulp. First off, it is not a 1.84Ghz CPU, but a 1.45, which can be overclocked to 1.84, if you want it to run hot. It has a large heat sink underneath, but no cooling fan. This proved to be  a problem.


I have to admit that, for all its shortcomings, I am impressed with this computer. It might have only 2GB RAM and only 32GB of eMMC storage, but it runs very fast under the installed Windows 10. I’m assuming that Windows 10 also carries out some sort of temperature control function, but as I deleted it soon after this arrived, I have not investigated further.

However, I wanted a flexible Linux computer so, after a number of false starts (Emmabuntus, Solus 1.2), I managed to install Xubuntu which ran very fast and does all I want it to do, but wasn’t robust. Initially I installed Xubuntu on an external hard drive, connected through the one USB 3 socket and was surprised at how fast it ran but again, this would lock up regularly. The advantage was that I had a large home partition and could run Win 10 if I so desired, but I didn’t. My second attempt was to install Lubuntu on the internal eMMC drive and use the external drive for the home folder. Once the external drive went to sleep, that did not work well. Later I discovered that this was an overheating problem.Rear View

Thus, Xubuntu on the internal flash. Even with all my regular programmes installed on the flash drive, there is still plenty of room left. Of course most of my data is on the external drive, it runs HD TV Video well and all the usual Linux Debian packages but, again it locked up after a while.

My setup

One problem, that I couldn’t overcome was one that I’ve hit, too many times, with Intel chipsets before (Cherry Trail in this case), in that they are not all well supported in Linux. I couldn’t get the sound chip to work under any flavour of Linux (Intel SST Audio Device (WDM)).

With three USB ports, one of which is USB3, WiFi, and bluetooth, this is quite a versatile PC. I’ve only had to add a USB3 hub, a cheap USB audio dongle and an external drive to get these features to work. WiFi, Bluetooth and the SD Card reader are not working either. That doesn’t concern me but it will concern some. However, it boots to the desktop in less than 30 seconds.


I’m impressed and I’ve reclaimed a lot of desktop ‘Real Estate’ but have yet to get a truly stable system working. Solus 1.2 is almost stable but is easy to lock up. Debian 8 is the most stable, so far, but I have yet to get a clean and fully working install as I can only work as Root for some reason.

Undoubtedly, I’ve invalidated the warranty, but Sumvison does provide a Win 10 image that you can download, put on a USB key and return the Mini-PC to its original state. I did try this more than once and it works well.

In summary a great desktop office replacement, at a good price, that is versatile, quiet, tiny and energy efficient and is much less expensive that an Intel NUC and some of the NUC competitor equivalents, but I’ve yet to get a fully functioning stable Linux distro to install. (I have learned a lot about UEFI in the process. Euck! I know it is secure against root kits, but working with it is just horrible.)


Update. After several attempts, and after climbing the steep UEFI learning curve, I have installed Solus 1.2 which seems to be working in a very stable fashion, word processing and changing video formats which is usually a challenge. I had to reinstall Win10 using the Sumvision download on to a USB key, then increase the size of the EFI partition, then install Solus 1.2 on an external USB3 Hard Disk. It has plenty of space and runs remarkably well. I’m not sure if all the effort was worth it, but I have reclaimed a lot of desk real estate. I have one or two issues with Solus, though, and as I cannot seem to get registered on the Solus forum, this has been abandoned.

Update 2. I think that I am finally beginning to understand this machine, or rather what works and what doesn’t.

This has worked for me, but I feel that there must be a simpler way to get Linux on this computer. Delete all partitions on the internal drive, then install Ubuntu. This will create its own EFI partition, but will not run in a stable form. Now you can install Debian, Solus, Ubuntu or whatever, on an external USB3 drive and it will run in a stable fashion, using the EFI partiton that the first install created. I’ve achieved this with Debian8 and Ubuntu 16:04 so far. But do note, that if, for some reason, the internal drive gets corrupt, it all goes to pot but this can be rectified by booting into a USB distro then using gparted to check and fix the internal drive. This computer will not work well with a corrupted partition on the internal drive, even if you are not using this drive. I do not understand why. However, all my many attempt to install some Linux distro, or the other, on this internal drive has ended in failure (but see below).

My Cyclone is running surprisingly quickly and in a fairly stable fashion, under Ubuntu installed on an external drive, connected through the USB3 port.

Update 3. One Ubuntu install failed and the reason given was that it might be due to an overheating computer. As I have had experience of overheating RAM that took a long time to diagnose, I deployed an old ZX81 trick. Mr Sinclair’s RAM packs would overheat and the solution was to place a carton of mik, from the ‘fridge, on the RAM pack (very 1980s) to keep it cool, so with some frozen ice in a container, placed on top of this Cyclone, I reinstalled Ubunutu. I have given it some fairly heavy work to do and it has worked faultlessly so far, if kept cool. Next, work out a cooling system!

Unless like me, you have suffered from bad tooth ache, that kept you up for a few nights, so with nothing better to do, I had the time to sit quietly and fiddle with all of this, you might want to pay the extra for an Intel PC stick that has its own cooling fan and I assume (?) runs better but will it be any better supported under Linux? I’ve no idea but if you’ve read this far, good luck.

Update 4. I’m convinced that running Linux gives this computer an overheating problem, despite its heavy use of heatsinks.


I tried adding some handy CPU heatsinks underneath and on top.


This seemed to improve the situation, but I still managed to lock up the computer when pushing it hard.

Next was a home made case using an old CPU cooling fan, running slowly, at 5 volts, so it was quite quiet.


I have decided that the most stable set-up for this computer is to use Win10, as delivered, on the internal drive, then run Linux on an external drive. I’ve used a USB3 flash drive for the swap file and UEFI file, now it is under testing to see if I was right about the overheating. Time will tell, but so far, my setup is performing well.


As there seem to be several variants of this computer on the market which, I assume, are all using the same motherboard, this must be an experiment worth pursuing. Time will tell.

Update 5.

I’ve managed to install Xubuntu 16.04, and now 16.10, which run faultlessly, 16.10 on the internal SSD, although with no sound, bluetooth, WiFi nor SD card support. As before, ethernet is fine and a USB sound adaptor has fixed all that I need to fix. Ian Morrison appears to have done a lot of work on the Intel Compute stick, but I couldn’t get his ISO to boot on my Sumvision BayTrail.
There is further advice about running the audio on Bay Trail computers, at 01.org  but this is beyond my current technical competence.
