 Note: the servos in the pictures will look different than the ones in your kit. They are functionally identical, so please don't worry!
+===== Pixy Modification =====
+For these servos to work properly, you will need to make a small modification to Pixy. Unfortunately, it requires a soldering iron and a bit of solder, but the modification is easy and doesn't require much soldering skill.
+The new servos are more efficient and require less power (which is good), but they are more sensitive to voltage drops. The current-limiting resistors (the big ones R18, R20) need to be bypassed. If they are not bypassed, the pan/tilt motion may be erratic (which is bad).
+Locate C25 and C26 on the back side of Pixy toward the right edge of the board. We need to short the two inner pads of C25 and C26:\\

+Do this by placing your soldering iron and heating up the two inner pads of C25 and C26 while adding solder. The solder should easily bridge once enough solder has been added:\\
