When i first started dealing with electronics i liked the idea of creating my own circuit boards at home. After a lot of searching on the internet i ended that the best way of building proto pcb boards at home is the photosensitive way. So i built an UV exposure box made of wood containing 2 UV philips lamps as shown in the fowlling pictures.

After a lot of tries and not well printed boards i ended that the problem was the light diffusion (btw my Workbench Power supply 0-30Volt 0-3A was printed on this box with very good result ).
