Lighthouse.
I made this little paper lighthouse one afternoon when i had a couple of hours to spare. I designed it in Inkscape before printing on some thin cardstock.
I'm using a picaxe 08 processor to "pulse" a white led every two seconds to give the impression of the light rotating into view and then away.
The picaxe ramps the led brightness from off to full and back again over the space of a few seconds to achieve the effect.




   Cutting the railing was a real pain as it is very thin. 
That's why it looks a bit warped.
I used sandpaper to roughen the surface of the led to diffuse the light and make it more visible from the side.
The chip and led are powered by two AA cells. They both fit easily inside the tower.
