This homebrew light box takes 3.5 minutes per side to expose double sided 6"X4" Ever-Muse boards and that's with normal daylight fluorescent bulbs. The single sided Ever-Muse boards are much more sensitive, it only takes 90 seconds. I have UV tubes for the box but never got around to using them since the box is much more useful as a portable light source. http://www.pbase.com/eldata/image/52321530 --- In Homebrew_PCBs@yahoogroups.com, David McNab <rebirth@...> wrote: >
