I can't believe you've got a box labelled "crystal microphones" :lol:

Random said:I'm looking at building a UV exposure box out of an old broken scanner - do you have to expose the entire board all at once, or can you do it in a sweeping motion for a longer time?
Also, where could I buy the Bungard Original PCB's?

actually i wanted to ask you guyz about the developers you use. is Sodium Hydroxide as good as the other developers like the universal developer (Sodium Metasilicate). whats the difference between the two
evandude said:It seems to me that laying the board on the table, setting the pattern on top, and then laying a piece of glass or plexiglass on top would be faster and easier than clamps... Not to mention, it would ensure that the pattern lays totally flat against the entire board, not just in the areas where it was clamped...
and a piece of glass or plexi should only cost you a couple dollars at the most, if you don't have one around already.
file down the edges of the board so there are no high spots lifting the glass up.I'm gonna try that. So basically, I will have to hope and pray to god that the glass is strong enough to flatten the transparency.
I just use the glass from my framed photos.Is there any specifications I should look for in glass (other than plexi-glass?) to minimize light exposure time?
I wear sunglasses when I have to look at the light, but for only a second.I got a UV light bulb at home (it isn't your ordinary house light bulb), and it is bright. I'm afraid if I look at it, it will blind me out.
Trial and error will dictate that, for your setup.and what is supposed to indicate that my exposure time is up when I do the board?
