Window Solar Heat Grabber Blueprint

Photos unclear, Directions also unclear

I recently purchased the blueprints for the Heat Grabber and was very disappointed when they came. The photos are black-and-white copies of what look like really old prints. There is so much black that in some places you really can't tell what is happening. And the directions are certainly not for novices. I'm glad that these "blueprints" are available, but I will have to research this solar heat panel in other places in order to get a clear vision of how to make it successfully.
