DIY Electric Art (LED Poster) -- Has someone made one before or is this just too easy of a DIY?
You can purchase the regular poster on websites for like $6. It seems to me like all they do is add a couple LEDs and an on/off switch and pump up the price to ~$120. Seems a bit like highway robbery to me.
Anyway, I just thought these LED posters were cool and would like to try tpo make one, but I am a bit unexperienced in the use of LEDs and resistors and the sort. Any help out there?
