Hi,
Looking at Suneater 3, it seems to me that the photo diodes are used as a
voltage divider. If you substitute the photo diodes for photocells you
would get the same result, a voltage divider. The voltage swing won't be
large for small angels but still worth a try. I use photocells in bi-cores
and it works fine. Give it a go.
