Arduino Wireless Power POV Word Clock

I have made this little gadget for the clock contest.The basic is my previous POV published here.

Step 1: Materials:

3 -5 V DC motor, Arduino pro mini 5V 16Mhz, RTC module with backup battery, IR LED and phototransistor, LED-s, resistors, some copper wire, a piece of coaxial cable, a piece of scrap PCB.

Step 2: Just Do It...

This gadget based on my previous project which is well described. I put pictures here because I think one picture tells more than hundreds of words.

Step 3: The Display

Step 4: RTC Module

Step 5: Photo Elements

Step 6: Coils

Step 7: Final Result

Step 8: Arduino Program

    Hi I'd like to know what gauge the wire is and its size (diameter).

    Hi,
    Actually it doesn't matter. The thing is that the transmitter and receiver coil must have same gauge and number of turns. In my case the wire was 0.3-0.4 mm and the diameter was determined by the width of the pro mini. Approx: 14 turns.

    That is some intricate work. I'm very impressed you must have some good steady hands. How did you manage to make such a beautiful flat coil?
