The Pi is still sort of "bleeding edge." If you have an Arduino (or access to one), I'd suggest working through the Digital LED Strip Tutorial. This might help narrow down whether it's a problem with the strip or with the code on the Raspberry Pi.

I finally got my rig working after wrestling with power issues! I had forgotten to connect the ground pin of the GPIO port and all of my issues there after came from running the Pi off of battery power.

I have a question about the code though. Is there a way to make it display the image over a longer period of time? I almost need to be jogging to display a picture at its correct proportions.

I got some great photos using this rig last year, but it felt very cumbersome to carry a laptop around just to switch up and run the script on the raspberry pi. Could anyone guide me to some information about making a physical toggle button on the raspberry pi to switch the script? I saw this on youtube, but it's all in german and i'm not really sure what terminology I should use when googling around.
