The only question is why?
In our school we could choose a topic we like and make a big work about it. I liked to create a small CSP-Tower (http://upload.wikimedia.org/wikipedia/commons/5/50/PS10_solar_power_tower_2.jpg). But for the creation of an heliostat would have meant much work and many hours for a friend who could have done those heliostats.
We decided to track a laser beam instead of the sun and we did those changes. I hope to get some expirience out of this project that I can realize later other maybe more complex things.
Isn't my project just a galvanometer (just without the lenses)? If I bought that I almost had no work. So I could call my aim 'Make your own galvanometer'.
Unless you have an uneven track, not clear why you need a vertical-axis mirror, unless that is part of the experiment?
It was mainly an option to develop the system if I achieved the first aim.
Unfortunatelly (bad time) I go to holiday on Saturday. I'd like to order the needed components tomorrow so that I can start shortly after my vacation.
