Modding my MK802 IV

Originally from June 2013

Well I call it modding, but <5 minutes doesn't really make a mod...

However doing it resulted in a 8-10 fold increase in wifi throughput, so well worth it!

You can see the finished article and the device opened up...

If you want/need to do this, open it up from the HDMI connector end - carefully with a "precision" screwdriver, once you've got it started it should come off easily - I didn't break any tabs taking it off... Also take the SD card out before starting...

Pic 3 shows the tools I used.

Now take the board out of the case, you'll see a red and a black wire (I think the red wire is Bluetooth, but not sure), its stuck to the back cover with some metal tape and some translucent yellow tape.


I used the scissors to make a small incision in the bottom of the case where the ventilation holes start, and clipped off a small area of the tabs from the top half.

The cable then neatly fits through the hole... I also made a matching slot in the foam so I can easily transport the unit.

Don't be tempted to fold the metal tape over on its sticky side, this seems to shield the effective part of the antenna, and results in even lower throughput (<.5Mb/s when I did it!).

Download speed is now 20-25Mb/s, upload is still under .5, but importantly latency to it from another Android (running Fing) is less than 10ms, with 0-1% packet loss compared to 30-40% before the "mod".

I wonder if getting an external antenna for it to "cover" the wire is worth it?

Also wonder if I should take the metal tape off - could this effect upload speed?

Why oh Why is it so difficult to find a new Ski Jacket? My old C & A one - about 14 years old - was great, but last season should probably have been its last.... So lets look around in the sales shall we, see what is available - up to the same price as paid for old trusty (~£100)... 

Oooh, there are LOTs of jackets in that price range, some REALLY good names too - Helly Hensen, Dare2B, Columbia, Navica, etc...

So I've had two delivered so far supposedly £200 jackets down to ~ £40 - what a bargain!!!

First one - a Navica Meribel - the zip seems to be terrible - tiny little teeth, one-way zip, no storm flap, and L is too small for me. Apart from that I quite liked it.. But...

So 2nd is a Dare2B jacket - again nice on first look, Storm Flap and decent sized teeth for front zip, but no pit zips, and the sleeves don't seem to have anything to stop snow going up them, AND only one-way zip...

Now, its probably just me, but one of the main things I look for in a jacket is a good 2-way zip, with storm flap.

The problem with buying on-line is that it is really tricky to work out if this is the case with a jacket. Most of the pics show the jacket closed, with the storm flap snugly closed, if fitted. I don't want to order yet another one only to send it back... So it may be time to unearth old faithful again... <Argh> </Rant>

For what its worth, my (1) prediction for tech for next year...

Having done a load of Christmas shopping from Tesco, Argos, and Amazon: we are going to see the wide scale roll-out of Google-Glass like technology to warehouse and customer service staff. Many of them already use headsets to communicate with co-workers and their stock system (some use voice activate menus which clumsily talk back to them asking for options - I heard one operative at Argos say to her headset, "Menu, log off" (and some other stuff), when she had to quit working on the collection desk to go and serve me at a till.

I can see massive benefits to these sorts of users to Google Glass type interfaces...

2DIS - What does it mean?
#2DIS  

Having sparked a little controversy with my post about Dimension(s) in TARDIS, and having watched Flatline - the best episode of the current run, so far, IMHO - last night I have to ask what do the DIS in 2DIS stand for?

IMHO it has to be 2 Dimension*s* In Space...

So time for another poll:

What does the D ins 2DIS stand for?

Like a lot of things xkcd...

This is impressive:

More DriveBender #drivebender  

Following on from my earlier post: https://plus.google.com/102221067073073008496/posts/DecsgvkQX8e

Following a, so far, short trial on non-production Windows 2k12 VM, colour me impressed. There are a few things I wish it did, but none that I need it to do which it doesn't.

I have been able to stitch togetether, isci, FC, and NAS attached storage into one pool: 

-> To remove drives (through the interface) and retain all files available.
-> To shutdown the backend storage (for a firmware upgrade) - the pool switched into read only mode - though not all files were available (as 2 out of 3 drives were taken out).
-> When the drives were available again I was able to re-merge them into the pool with no loss of files.
-> To force remove a drive from the pool and keep the files on it intact for viewing outside of DB (so no loss of data if DB stops working!).
-> To mount drives used in the pool with their own drive letter, so you can access files which are on the drive directly, even when they are in the pool!
-> Set up duplication - so that no file is stored only once on the array - though I'd like to be able to direct these duplicates either to be distributed across the array (this may be the way it does it) OR direct them to live on specific drives.
> Set up limited tiering - only 2 tiers - 1 landing zone (1 disk where files get written initially) and 1 Storage zone (the rest of the pool - once the landing zone is "full" (defined by % used/free) or at certain times of day   DB moves the files off to "slower" disk... I'd like to see this extended so that regularly accessed files are kept on faster disk...

On the whole a very good product - Wish I'd known about this product 18 months ago - would have made my life a LOT easier...

Trialling DriveBender

To stitch together various odd bits of storage lying around into one target for backups... It seems to work REALLY nicely - currently have Fibre Channel, iSCSI, and NAS (SMB) drives in one pool.

The NAS is the most interesting bit - I can still access the NAS share from another PC while it is being proxied by DriveBender, if I add files in the right place they can then be seen by DriveBender...

If I remove the NAS drive, files are taken off of the NAS and distributed across the rest of the storage as part of the removal routing...

I've yet to work out a way to keep the files on the removed drive, but that may be down to the duplication algorithm... Not yet sure if it does real tiering though...

Kudos to my Dad +Roger Owen who originally made me aware of this!
