Meet the Nurugo Micro: a digital microscope that combines with your smartphone to let you magnify small objects and take enlarged photos and videos. The device is easy to install and does not require a wire or any additional battery to work. You get up to 400x magnification.
Micro is compatible with iOS and Android devices. It weighs only 3.89 g and measures 0.5cm in thickness. Yet another interesting Kickstarter project.
