First thoughts:
The Single I got was pretty stock. From what I have noticed, the first generation singles had a nasty habit of blowing up the FET drivers. A number of people have posted pictures of the results and they are not pretty. Which is not good. However the reason for this I think is not enough heat sinking on the chips. So when I flashed my unit to stock 1.2.9 software I made sure to include the following heat sinks on the bottom of the board:
Putting these sinks on gives some bottom cooling to the FET chips which I think will help the life.
Next up is to think about how to boost this unit. The normal way to do it is to add chips, and if your board is like this then you can do it pretty easily:
Note how this board has 8 chips to the left, and a full complement of components on the right. All you need to do (I think) is put chips on, as the 1 volt supply line is ready to go.
However if you're like me your board is more like this:
It is going to be a bit more of a problem.
Note how some components are missing. Especially the big capacitors, the smaller surface mount caps, and of course the FETs. And the FET driver. However the supporting small chips all appear to be there, so if we could mount the other stuff we would be in business. Equally important, the solder is there for the components, so it might be fairly non-impossible to add them. Some of the parts are kind of unique, but oddly enough I have a blown up jally sitting here.....
More to follow as I start working on this. You might be able to add a single chip on the right side, but that will probably stress the FETs out beyond their capacity (ie: They go boom). Edit: You can't. The 1 volt supplies on a single board are isolated from each other; the one on the right runs the right chips and so forth. Therefore there is no 1 volt power unless you were to jumper the pads which would be beyond stupid. :-)
More in a bit.
