Picture story

A small EL-foil with the converter. The converter needs 5V DC. I´m using a PWM output to adjust the brightness. 
The scale is designed with Corel Draw and printed out on an overhead foil. 
One of the mini servos. As smaller, as better. Approx. 7 EURO each. 
The scale glued on the EL foil. 
Testing 
My new small CNC machine, controlled with a 12 years old PC. 
Milling one of the five plates. 
Here you see all the milled plates. 
The scale was laminated to guarantee the electrical isolation. 
The mounted servos. On the upper right corner you see the opening for the converter.
