Full Graphic Smart Controller case with Brightness & Contrast adjustment knobs

This is a remix of Pablo's case http://www.thingiverse.com/thing:213852 with added holes for one or two potentiometers.

I created a small pot knob using http://www.thingiverse.com/thing:41274 and added a shaft.

Insert the pot knobs put the washer on the other side (glue if necessary), align the small cross on the bottom of the shaft with your pot before putting the top on the case.

To add a potentiometer to control the backlight brightness do the following:

1. Desolder the smd restistor called RBL
2. Drill three small holes as shown in the photo (I used a 0.9 mm bit make sure not to drill through the nearby tracks)
3. Insert the 10 KOhm pot (103) and solder the central leg (wiper) to pin 2 on the LCD.
4. Solder a 100 Ohm resistor between LCD pin 4 and leg 1 of the pot.
