Each time I try building one of these things I get a little bit closer to achieving a solid heliostat design. This one still needs some improvements, but it does at least work well enough to try it out in the sun. I will post more on it in the near future, but, for now, here are some pictures to get the ball rolling.
Each of the 6 1ft^2 mirrors is adjustable. This way, the light can be focused on a smaller target. I originally planned on adding 12 mirrors total, but I decided to keep it at 6 for now while I try things out.
For now, I’m only shining the light through a medium sized window.
This picture doesn’t really show it, but the reflected light does a good job of lighting up the room. Standing in front of the light beam feels just like standing in front of the light from the sun.
