Any suggestions on how to build a rotating solar sunflower?
Any suggestions on how to build a rotating sunflower (span of about 3 or 4 feet) to hang on a wall (sunflower will be made of fabric or perhaps a sticker image on foam)? It's in front of a series of large windows, so I'd like it to be solar powered. I was thinking of working with toy motors, but I think the RPMs would be way too fast - I'd like it to move fairly slow, maybe completing a full rotation in about 10 seconds or so. Any suggestions on what type of motor/solar combination (and where I can get these items) would be great. I'm trying to mount these on walls (multiple numbers of them in different sizes).
