Make an Arduino-controlled UV LED PCB Exposure Box

If you're etching PCBs at home and using or considering using the photo-resist method with pre-sensitized boards, then Instructables user "relic1974" has the project for you. After experiencing varying degrees of success, they realised a more accurate exposure timing control was required and thus created a fully-automated UV exposure device based around an Arduino-compatible board. His device has a user-controlled timer which activate 63 UV LEDs to ensure a perfect exposure every time. The device and process is demonstrated in the following video (skip to 2:30 to see the UV LEDs in action):


That's another interesting and genuinely useful Arduino-controlled project. For complete instructions visit the project page. And for more, we're on twitter and Google+, so follow us for news and product updates as well. 

If you're moving Arduino projects to your own PCBs, blown the MCU on your board - save time and hassle with our new ATmega328 microcontroller pre-loaded with the Arduino Uno bootloader:

It's the same one as found on our ElevenKitTen and the original Arduino Uno, plus it has a very useful pinout sticker attached to save confusion when wiring it up. So for more information and to order, click here. And we also sell the stickers!
