I usually connect it to my "DIY ATmega UV box processing unit" (arduino based). It's a little attachment for controlling the light intensity, has a digital timer, it's also equipped with a backlit LCD screen
Just so you know, when you go to a local PCB fabrication service, they either use Presensitized PCBs or a Laser CNC. This project is only recommended for experienced users!
How To Use It:First of all this gadget only works with Photo-positive PCBs, NOT FOR TONER TRANSFER METHOD !!! I've done the process with my "DIY Arduino Motor Shield", from my previous ible guide. Since summer (school break) just started, I'm planning to post more ibles about Arduino projects with PCBs, I'l show you how I develop my presensitized PCBs on my next ible guide.
Why Use Presensitized PCBs instead of Toner Transferred PCBs?Based on my experience presensitized PCB making is one of the most reliable and efficient way of fabricating precision made PCBs. As we all know from our experience in making Toner Ink Transfer PCBs, there's a lot of broken lines and blotted ink, this is bad since some lines could short the project after etching. The advantage of presensitized PCBs, is the reduction of broken lines. It's so precise, you could make PCBs with lines as thin as a strand of hair!

Tools, Materials & Parts:
- Ultra Violet LEDs (54pcs.)
- Plastic Enclosure (Project Box)
- Old 5v Nokia Cell Charger (any wallwart)
- 3.5 Jack for power connector (Male & Female)
- 2mm Acrylic/ Plexiglass/Glass
- Leatherman Multi-tool
