If you're making your own PCBs - or thinking about doing so, this UV light exposure unit by Jan Borsky could be quite useful. Controlled via an Arduino-compatible circuit the unit has 450 UV LEDs which create an even light source. There's also an on-board timer that can allow fixed exposures of various lengths. Another use for this project could be to replace the UV LEDs with infra-red ones, and make a huge illumination device useful when shooting night digital photography.
Either way, you can find out more and also download the design files from Jan's website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're prototyping Arduino projects on solderless breadboards, blown the MCU on your board, or making your own such as the exposure board mentioned above - 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 Eleven, KitTen 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!
