[Ronja] Ronja parts from Science Museum in London

[Jakub Sykora]

I see the lens could be used as these are fresnel lens, but I don't know 
how to use the retroreflector as it only transmists signal back to the 
same direction it received. Maybe for high quality aiming these 
monsterious lens :]
This could be such fun to test. I heard about implementing some easy 
morse code beacon with ID of the watch-light in mediterinean sea as this 
light was occupied by a radioamateur. The beacon was readable in 
distances over 80km.
