I also color printed the picture used for the lithophane and glued it to the back of the panel.

To get the lamp to work I used the following parts and hot glued them inside. There is a recess for the LED:

I used a 27ohm resistor based on using the above parts from adafruit.

Otherwise use a resistor of appropriate value (Use http://ledcalc.com with the parameters from your sourced LED, voltage source @ 5V). Make sure your circ
