Solar Projector
A post over at TWTM got me thinking about the wonderful solar projector SK made back in ‘03. He had great fun with this:
He was thrilled cause he could see the sun spots.
He eventually used K’Nex to build a huge stand for the binoculars and a holder for the large white board. The sun is projected through the binocular eyepiece onto the white board, and you use both the binocular focus piece and the distance between the binocular and the white board to bring everything into focus.
The spots, black, can be seen on the sun. Over several weeks he tracked where the spots were and he was actually able to watch them move across the suns surface.

We got the idea out of one of the Reader’s Digest Science books, probable How the Earth Works. It was really easy to put together, and the only tough part was focusing it all, and remembering that the eyepiece had to be toward the sun.
It was awesmone to see the sunspots.
