FetchTV YX-6936U Boot messages from rs-232 header inside unit




Inside the FetchTV box is a straight 6 pin header, if you look closely at the white writing near it, you will notice the assignments given by the first 4 pins.

The other four pin header has 3.3v and probably other things.

The data needs to be converted from TTL to rs-232 using a max232 chip.  Look on ebay for rs232 translator boards.  In my case the 5 volt rail powered my translator board, I used ground ground one of the tv tuners.

The connection speed is 115200 N,8,1.

As soon as the boot commences, it begins to spit out data.

The full dump is here

Interesting lines from the boot sequence:
BCM74130011
Shmoo Version=3.5
BCM97413B1 CFE v2.21.2679, CFE core v2.12, Endian Mode: Little
RSA encryption


So much like the Tivo, Generation 4.....

If anyone want to share their FetchTV dumps, please paste on pastebin.com and put a link in the comments below.

ATI Radeon 9600XT disassembly, cleaning and repair

Why bother with this junk, an old ATI card which was full of dust.

A complete tear down and wash with solvent was required.  Also the fan was cleaned and reoiled.


Choking

Two small black tabs need to be pushed out to remove the heatsink

Remove the three screws holding the top plastic case to the heatsink


Another three screws hold the fan, the bearing is under the label

underside of the board

All cleaned

Ubuntu tool for finding duplicate files, images, pictures - Fslint

Fslint is great, it can scan several directories and find all your duplicate files, for instance duplicate images or music files.





You can bulk select the duplicates using selectable criteria to get rid of them.

It also does tonnes of other things too like empty directory detection and searching for bad filenames (Samba?)

A must too for Linux.

Farmers retaliation for unjustified coal seam gas extraction in australia

There are many problems with the extraction of coal seam gas in agriculture land.  Farmers end up with ground water that burns and becomes contaminated.

Since the crown owns all minerals, mining companies are allowed to enter anyones land and mine the minerals without permission.

I wonder if one solution of getting payback would be to drill another well into the gas seam, pump air into the seam and then ignite it so the gas "safely?" burns/explodes underground....
