led reader 56 columns wide. stores messages without computer.
I chose to just show pictures. the actual build is complicated.
The txt is step by step. The real hard part is gluing 300 leds to
the glass and keeping it all clean and crystal clear. This is more
art than electronics. My 'led on pc' makes the build easy but
you loose the artistic affect of the glass. To see in real life is
rewarding. Stay tuned for my 'time square patr1, part2'
An awesome reader that's folded into a square.
Step 1: Many TYPES of Readers

Step 2: Parts of the Displays

Step 3: Displays, Keypads

Step 5: Downloads
here are the downloads for the build
if you can glue the leds to glass then you
are half way finished. Tips on the build are in the .txt
My latest readers are enclosed in epoxy and that makes the
leds POP so the display looks 3d.
