UV Led Exposure Box DIY

Here you can find a photo tutorial about the construction of the project!

The electronic parts that you will need are:
- 48 high power uv leds (prefer straw hat)
- 8 resistors 150 Ohm 1/4 watt
- 24 VDC power supply

How to construct.

It is a simple idea.
There are 8 paraller arrays that consists from 6 leds in serries with a resistor (150 Ohm).
We power them up with 24 VDC.

Tests.

After a lot of tests we notice that the best exposure time is about 2,5 minutes.
