Right so currently my pc is running an old quad core Q6600 CPU with 8gb ram and 512mb graphics card and to be honest it’s starting to feel the strain.
Firstly it’s currently used as a family pc but struggles with a couple of different users logged in etc. My eldest child uses for browser based games/Minecraft etc but there will be a time soon when he wants to play more demanding games.
So being on a tight budget I’m going to try and cobble together something half decent that will play games at 1080p.
Now I was initially as previously buy individual components and build one but having used a Lenovo M91p sff I thought to save time and money I would get the tower version chuck in some more memory and a graphics card job done.
After some searching I found some 4GB Kingston memory modules for cheap on ebay.
After this the project stalled as busy with other things when I came back to it I found the M91p came with an i5-2400 CPU but the case and psu was also limiting. Undeterred I carried on searching and found a Lenovo M73 on eBay with an i5-4460 and would also be able to use the ram I had previously purchased. Also liked the fact it already had usb 3.0 ports and card reader. Stuck in a bid and won it for £125 posted.
Now the one of the limiting factors in these prebuilt machines is the psu as they weren’t originally designed for gaming use.
Lenovo M73 – £125
2x 4GB Corsair DDR3 1600 MHz CAS 11-11-11-30 Dual Channel Memory – £35.30
Graphics card – Nvidia Geforce gtx 750ti 2gb – £60
Maplin A26LW A5-V11/A5-V12 OpenWrt Ralink RT5350F Mini Portable 150Mbps 3G/4G WiFi Wlan Hotspot AP Client RJ45 USB Wireless Router
So while randomly browsing a deals website I came across a USB wifi router/hotspot on sale at Maplin for a mere £2.00 and as my tinkering desire took over I decided to order a couple. https://www.maplin.co.uk/p/maplin-3g-n150-wi-fi-router-and-hotspot-a26lw
These devices all appear very similar physically but your mileage my vary on functionality i.e they may have
A restricted bootloader that doesn’t allow OpenWrt images
Limited Busybox shell available by telnet
More complete Busybox shell
Board is marked A5-V12 and chip is an Ralink RT5350F. From my reseach I found other boards are marked A5-V11 so used that as a starting point.
Clock 239 MHz
4 MByte Flash (GD25Q32)
16 MByte RAM (EM639165TS-6G)
USB Host 2.0
10/100 Ethernet switch
Micro usb as power source
For this configuration I used my windows desktop and connected my 2nd network interface to the device.
Default ip is 192.168.169.1 and DHCP is enabled
Telnet is enabled by default and can login using admin/admin
BusyBox v1.12.1 (2011-10-22 23:04:50 CST) built-in shell (ash)

The stock bootloader is minimal/strangled one and needs upgrading and doesn’t allow flashing of OpenWrt firmware via the stock gui.
The easiest way to load a new bootloader and firmware is to download the files from a webserver. I used miniweb after installing I added the following files the htdocs directory
and then run via windows command line
C:\Users\pc\Desktop\miniweb>miniweb.exe -p 80 -d
MiniWeb (build 300, built on Feb 28 2013)
(C)2005-2013 Written by Stanley Huang
Web root: htdocs
Max clients (per IP): 32 (16)
URL handlers: 2
Back in your telnet window download the two files
# wget http://192.168.169.2/uboot_usb_128_03.img
Connecting to 192.168.169.2 (192.168.169.2:80)
uboot_usb_128_03.img 100% |*******************************| 135k --:--:-- ETA
# wget http://192.168.169.2/firmware.bin
Connecting to 192.168.169.2 (192.168.169.2:80)
firmware.bin 100% |*******************************| 3328k 00:00:00 ETA
Next write the new bootloader
# mtd_write write /tmp/uboot_usb_128_03.img Bootloader
Unlocking Bootloader ...
Writing from uboot_usb_128_03.img to Bootloader ... [w]
Now write the new firmware
# mtd_write write /tmp/mini.bin Kernel_RootFS
Unlocking Kernel_RootFS ...
Writing from /tmp/mini.bin to Kernel_RootFS ... [w]
Once all complete reboot
While it's rebooting you'll need to set a static ip on your desktop interface that is connected to the device i.e
Once the deivce has rebooted it will be available via 192.168.100.1 and again telnet is enabled.
=== IMPORTANT ============================
Use 'passwd' to set your login password
this will disable telnet and enable SSH

CONGRATULATIONS you now have a minimal OpenWrt image installed. You can now also upgrade using the sysupgrade function but you need to be aware of the 16MB memory limit.
Please let me know what you are using your devices for and share any custom f/w you've built for it.
As a long time avid fan of HHGTTG I stumbled across a website which had the audio files for the original radio show. In the interests of archiving I have downloaded them to TOP for hosting.I will be adding the links shortly.
Time for part 3 of my DTi servicing guide and this time it’s the oil filter.
My service book states oil and filter changes should be done every 20000 miles or 12 months which ever comes sooner. Personally I do mine every 10000 miles or 12 months.
As I couldn’t be bothered to roll around on the floor to drain the oil via the sump plug I used my 12v pump to empty it. (I will get a pic of the sump plug when I get a chance)
Parts Required: Oil filter – Again I used a Bosch one as it was only a couple of pound more than another brand from eurocarparts *Your new filter should have come with 3 new rubber o-ring seals make sure they are there as sometimes they are missing!*
5l Oil 10w 40 semi-synthetic – Up to you which brand you use I just get whatever ever decent one is on offer at the time. This is the stuff I usually use eurocarparts
32mm socket – This can be had from ebay, amazon, motor factors etc.
1, Run engine up to temperature
5, Once tube is running clear(ish) switch off and remove
8, Use 32mm socket and undo housing in clockwise direction
12, Attach new filter to holder and insert into housing and tighten up anticlockwise to 26Nm
14, Run engine and check oil level again when cold.

So my tv broadband and phone package is due for renewal in a couple of months and it is clear i only actually watch a couple of subscription channels and mainly Discovery. I don’t have sports or movies packages as have no need for them as not into football and 99% of the films are repeats. During my search I came across tv player which looked a good deal as it has exactly the channels I wanted for sensible monthly price meaning all I would need to pay for is broadband from another supplier and there is currently various deals on at the moment. As TV Player is a streaming service I thought I would check the subtitles situation. A quick Google found this post http://support.tvplayer.com/forums/229619-ideas-and-suggestions/suggestions/5458900-subtitles-for-live-channels-as-this-is-the-best-ap the top post by ‘TVP Admin’ from 3 years ago said they are “currently working on it, they also said the same thing in 2015.
So after 3 years of working on it they still can’t provide subtitles? With live tv via other providers Discovery programs have subtitles so unsure why it can not be done via a streaming service (if anyone can shed any light on this please comment below). In this technological age we shouldn’t still need to be begging for accessible tv services!
I have gone into full keyboard warrior mode and dropped and email to the Discovery channel for their feedback.
As an avid viewer i have been looking for other tv packages that can supply your channel as i’m paying too much for chnnels I don’t watch and during my search I came across https://tvplayer.com/ being deaf I contacted them re subtitle availability and I was told “We don’t offer subtitles at the moment but we hope to have this feature available soon.” apparently they have been “working on it” since 2014!. I know live tv shows have subtitles but where do the limitations come in as BBC iplayer etc have subtitles? Is tvplayers delay due to changes needing to be made by yourselves?. It’s very saddening that some providers are dragging their heels with accessible tv services.”
I got a reply from discovery
“Thank you for contacting Discovery.
Our channels are available through Freeview.
Sheena | Discovery Viewer Services | discoveryuk.com”
“Good morning thanks for your reply however it doesn’t answer my question re streaming service tvplayer offering subtitles.
Also Discovery channel is not shown on the freeview channel guide https://www.freeview.co.uk/why-freeview/channels#K02KVJU0jI0qsEYj.97”
“While we are included in these channels, unfortunately we have no say in their production or subtitling facility.
You would need to contact them.
Apologies for any inconvenience caused.
Discovery Customer Support”
So there you have it looks like its a TVPlayer issue rather than Discovery.
