Rigol DS2072 200Mhz Bandwidth and Full Option Hack

UPDATE:

You can now generate keys and permanently activate all of the options and bandwidth without any extra hardware. Here is the c code which will generate the keys (it is the most up to code from the thread with a couple of modifications). All you have to do under Linux is place the above code (and fill out the private key value from the forum or use the pastebin link's code) into rigolkey.c. Alternatively there is also a Windows exe floating around on the forum there too which you can use.  

Make sure you have g++ installed and perform the following:
mkdir miracl
cd miracl/
wget https://github.com/CertiVox/MIRACL/archive/master.zip
unzip -j -aa -L master.zip
bash linux (or bash linux64 if running 64bit OS)
cd ..
gcc rigolkey.c -I ./miracl/ ./miracl/miracl.a -o rigolkey

Now run:
./rigolkey [your device serial] [option parameter]

Use "DSA9" for the option parameter to convert to a DS2202 with all options enabled. There are more options available here. The device serial number is located on your about screen, or on the back of the scope. If you have somehow managed to reset your serial number to a default value on the about scree (DS2A0000000001), then use that rather than the sticker at the back.

It is recommended to have at least firmware version 00.01.00.00.03 before entering the licence. Now apply the licence key that the keygen spits out. This is located under Utility>Options>Setup>Editor=ON. Enter the code using the intensity dial and button then hit Apply. It should then say "Option Installed!" if you entered this correctly. You now have all options enabled including 200MHz bandwidth.

 Reboot and your options will remain:

Raspberry Pi Model B to Model A Conversion Cleanup - Part 2

Be sure to see part 1. A lot of the components on the board are now redundant as they are no longer used/connected, so for cosmetic reasons we can now remove these from the board. The easiest way to remove them is to load a soldering iron tip with solder and flood the SMD components. They should just flow away and join with the solder lump on the tip and leave a nice clean finish.

Firstly on the top, you will want to remove the components in the spaces marked red. You can also remove the RJ45 connector if you wish.

First Raspberry Pi Model A 512MB Off The (Re-)Production Line - Part 1

Who wants to wait (or pay highly inflated prices for pre-production run) for the Raspberry Pi Model A, when you can have it now for a low price of $36AUD complete with a 512 MB RAM update?

Cosmetically and functionally the Model A has removed the LAN9512 IC, Ethernet port and the secondary USB port. Under the hood, they have also designed the PCB to accommodate both Model A and B configurations, depending on the placement of a couple of components. In this series, I will be converting the Raspberry Pi Model B to a Model A with 512MB RAM.

Let's first compare the two boards by eye. On this page they have nice pictures of the Model A board. Looking at these pictures and our current board, we essentially want to remove the extra components from the Model B to match the Model A.
