Word Clock Update #4 and #5: The Display

There are two main parts for this project.  The Circuit Board, and the Display.
The Display is the part that people will see, so you have to try for this to look professional.  There are different ways that you can make a display of letters.  This is just one way:  I will use a frame from IKEA.  They have 9x9 inch frame which is almost 2 inches deep.  Plenty of space for the circuit board.  To get the letters, you can have this cut out of plexiglass or metal, but I will just print them out on transparencies for my first version, where the background is black and the letters are transparent to show the light.  You can come up with all kinds of creative ways to make the display.

The letters on transparencies.  English version

Above you see the LEDs mounted on a cardboard, with dividers around each word, to avoid bleeding light from one word to another word.  There were 99 LEDs used here.  One per letter.  There are letters in the display that are never used, so these do not have LEDs.

Here you see the back of the cardboard structure, where I started soldering the resistors. One per LED.
