Building LED UV Exposure Unit for under $60 | Alternative Photography, Screen Printing, PCB...

Тәжірибелік нұсқаулар және стиль

This week I built myself an affordable UV Exposure box using LEDs and a plastic box. During short winter days there is not much sun here in Slovenia so it's really hard to work with techniques like cyanotype, salt, albumen, lith & carbon printing… This is why I have decided to build myself a 40x60cm UV LED exposure box. It's not just useful for us photographers that love alternative techniques but can also be used for screen printing, PCB making, Whitening and so on… I designed it in a way that it has two power levels so it can be adjusted if needed. Enjoy!

    Congratulations! It is, by far, the most practical project on this topic that I found on Youtoube: simple tools and materials available to anyone. I think that an extremely simple timer would have made it even more practical. Congratulations again.

    using intrepid cameras you'll be somewhat familiar. their enlarger offerings have a built in contrast adjustment from grade 00 to 5 but their light source doesn't have the proper nanometers to use the 5, requires low 400''s to work properly. this would be perfect. actually looked at these this morning

  • @skyhawk5983

    Great video and here is a PRO TIP: I would highly suggest anyone who plans on building this to spend a few dollars and buy connectors for the LED strips. I have years of experience in soldering but I wouldn't spend the time cutting/stripping 40 wires, tinning each end (80 in total) then soldering 40 connections to the end points of the light strips. This takes time even with experience! If something goes wrong you will need to diagnose which contacts are failing. Do a bad job and you could short out your lights. Buy connectors, they are cheap and you can be done in a fraction of the time. That being said, great video for anyone wanting to save money building an exposure unit vs spending $300+ dollars.

    Just a little tip. If you look at your pliers, you see one side consists of two wedges, while the other side has two, essentially parallel surfaces. Makes very little difference in cutting the wire, but peeling the insulation is different. The direction you used causes squeezing of the insulation, making it to try sticking. Turning the pliers the other way pushes the loose end along easier! Try it!

    This is great! I built one back in college using 24-inch T12 bulbs. It does the job, but it's bulky and ugly and I've been thinking about building a new one that I can build underneath my enlarger table so it's more out of the way. What kind of print times are you able to get with this setup? I've been debating between going with the 395nm LED strips or the 365nm. But the 365nm are crazy expensive. The tradeoff is that many processes are apparently a bit more sensitive to the shorter wavelength light, but I'm not sure it's worth the cost.

    I use my timer on the phone. But it would be a nice upgrade to this setup!
