(edit, added Eclipse pictures)
As a break to reading about XAML data binding in Windows 8 Metro applications I decided to make a solar observing telescope for the upcoming Eclipse around 5:30PM here at my Mom’s home in Los Angeles.
I raided the Christmas supplies for a couple elongated toilet paper rolls. One slightly less in diameter than the other. I created a shim between the two with some thick packing paper to keep the tubes relatively aligned. Then I cut a viewing hole at the bottom and used a couple rubber bands to hold a piece of paper on one end and some aluminum foil on the other. I pierced a pin hole in the aluminum foil. I may attempt a darker paper on the viewing end.
Fun. Didn’t take that long to construct, and it’s not every day you get to experience an eclipse. Next time I want to get a long piece of PVC.
I found a couple useful resources out on the ‘net.
