Lil'Leica has paperclips holding up its head like a lantern - on each side. One paperclip bent through experimintation to connect to a small servo superglued to the back of the lens. Between back of lens and servo is a single rgb ledpixel with leads coming out top. I use the original lens motor to control "focus." Arduino nano is the brain and it is held onto the two lantern-hanger paperclips with a tiny rubber band.
The photo is from early on. Current pictures coming soon.
