In case you missed it, Logan has posted several pictures and videos of the heliostat he built for his art project “A Description of the Sun”.
The mirrors are made from Plexiglass, which is how he was able to cut them into circles. This is a very handy trick for anyone who wants to build a heliostat with mirrors that have more style.
Note, if you look closely in the picture below, you can see that he is using the Sun Harvester Shield and Sun Harvester Driver Board. It’s always cool seeing people making stuff using stuff that you yourself have made!
