I put one of these together yesterday with a 32 pixel strip from Adafruit strapped to a PVC pipe. I got something, but the image was not displaying correctly. Then I looked at the test images you posted (thanks for those, they helped connect the dots :)). Based on the resolution, your strip must have been 92 pixels long right?
You must have been traveling at a good clip too? To get results from my setup, it had to really be moving!
I love the POV thing but got intrigued with the idea of a matrix. I read some of the other posts about this and I started putting together a matrix that will be 10x16 from the 5 meter LPD8806 strip I also bought and wondered what it would take in the code to make it display on the matrix?
I ran the strips in a zig-zag pattern and bought the 10 amp unit as well to handle the power required.
I'm new to Python and electronics, so just looking for a push in the right direction.
