This is a very low tech experiment so that I can better understand heliostats.
I do this experiment because of my lack of understanding of heliostats, because of an answer on wikipedia i did not understand and because of a big arguement about heliostats on instructables last year.
Also, there is very little information on the net about how mechanically powered heliostats work.
They were common use over a hundred years ago.
It is snowing today march 9 (usually they have a flower count here in early February!) so this gives me time to put this instructable on as requested.
Step 1: Materials and tools
a tightner for a a clothesline
a crocodile clip
a piece of tie wire
and a protractor picture that I downloaded from the internet
You need a bench drill to drill holes straight into wood at right angles to the surface.
A hand drill is probably not accurate enough.
Screwdriver is also needed.
