LED Matrix Wall Answered
THe artist Erwin Redl is very well known for his "LED Matrix Wall"
I went to go see it this weekend, and I wanted to know how it was done, sadly noone there knew :'(
So Im passing it on to Instructables! Help a newb create a wonder in his room!
Now i dont get how it is set up at ALL
i always thought the bottom needed to be connected to a negative...
can ANYONE help describe how this works, as you can see the bottom of the line, is a weight.
im so confused!
Im just trying to power as many LEDS as possible, and this seemed like a better way then my drawing with a white background...
