Since my order for more Raspberry Pi’s came in for the rest of the projectors, I needed to do a real test! I had some old left over black shear fabric that we used to have as curtains. I ran a line, hung the shear, and fired up one of the projectors to see how well it worked. It worked really well but for the projectors “black” level is still a little too visible. There may be some settings I can adjust or lighting tricks I can try to blur the edges. But I Amarillo pretty happy overall.
