Since I learned so much from this forum, I’d like to make contribution to this community.
Here’s the way I made my own version of UV box, little budget and only few parts needed.
First, get these parts ready, 12V/2A power supply, 5m LED string, 1pc of transparent glass and stainless box.
Here’s the picture.
And then pave the 5m long LED string onto side walls, since this is a 25x25x25 cm cubic box, the LED string should pave 4 rows on each wall. Plug in, it’s beautifully lighted.
I just broke the glass before right before taking picture, otherwise you’ll see the prints should be like floating in the air(middle line).
