Get all those weird endoscopic thoughts out of your head*. This USB Snake Scope “is a handy pipeline inspection and surveillance tool to help examine places that are hard to reach.” Powered by your computer’s USB port, the water-resistant camera head has two adjustable white LEDs for illumination and a 54° viewing angle f/2.8 lens with a 6 cm to infinity focal distance. Its 1/6″ CMOS VSA sensor (640×480 pixels) can take up to 30 fps videos, and also has a snapshot function. This flexible borescope’s cost ranges from $49 (but from a UK supplier, so shipping could be a tad expensive) to $74, and you also get a clip-on magnet for retrieving ferrous metal objects.
