We all have different reasons to make things. If you wish to use a processor
to set the exposure time, I think that is wonderful. I recently spent a few
hours building a punch that could have been bought at Staples for $4. It is
a hobby so there is no need to justify the effort.

I have no enclosure and no reflectors. Just two bare bulbs hung 2.5" above
the board being exposed.
