Ecotech Reeflink USB Power Conversion

My Ecotech Reeflink was working happily until all of a sudden, it wouldn't power on. No lights at all!

A quick poking around showed that the large black IC on the board inside had failed (responsible for converting mains AC voltage to 5 volts (0.8amp peak).

Seeing as though I bought it second hand and essentially had no warranty anyway etc, I decided to convert it to being USB powered!

Parts Needed:
* Soldering Iron
* Solder
* Snips of some sort are handy to cut off the parts we need to remove/clean up etc.
* This 3D print :)
* Pololu usb07a board
* Some wire (something like 26awg silicone wire is good)
* 2x M2 nuts
* 2x M2 4mm bolts
* [optional] Double sided tape or glue (for re-attaching the rear sticker! The original glue doesn't cope well with being re-attached) - could just remove the sticker too.

Steps:
* Note; some pictures on the internet show a large black heatsink over the input power section - mine didn't have this (perhaps why it failed! haha). Switchi
