Ive found that my photosensitized boards are quite sensitive to light, so much so that I can only have one small bulb on in the other side of the room, which makes it very hard to see.

I was thinking of getting a 1W red LED and mounting it on the ceiling above my workbench. This won't expose the boards will it?

yea yea, i know you and your PNP blue sheets :roll: . Im sure they work great but I like phototransfer a lot :lol:
 

Sure, but you have to make sure your cellophane blocks all the wavelengths your board is sensisitve to. How do you verify this? You don't. You buy a $5 safelight The same goes for the red LED. Make sure it doesn't produce sensible wavelengths... buy a real safelight

Talk to any photographer who does his own darkroom work, you'll get stories on how they tried to paint light bulbs, enclose it in red plastic boxes... It always ends up smelling funny :lol: The red LED's a less dangerous option, but still no match for the "real" thing in my humble opinion, which is just a bulb painted the right way and guaranteed not to smell or produce toxic fumes.

You bet! :lol:

How big is this thing? Do they make these in the UV variety? I like UV LEDs for my own little circuits, a few 1W would be way cool at night in my room

Sure arn't cheap :lol: , there are probably cheaper/better ones around though.

Found this interesting as a looked through them;

Good idea, makes it easier to heatsink I guess.
 

You and me are in the same boat. It seems to be economical, and best of all NEAT!

Ever since switching, I managed to put two 0.2mm wide tracks together with a 0.5mm spacing in between them. So far, I have only used a quarter of a transparency, and that $1.50 is lasting me a while.

now I can CRAM without mistakes.

anybody want my used wax? :lol: j/k
 
The red LED works wonderfully!

I can actually see what Im doing. It even looks cool when all the lights are off, sort of like a submarine :lol:
