Endoscopic cameras aren’t just for surgeons and spies. A compact, flexible, high definition camera can also be a seriously handy (and fun) tool.

This WiFi HD Waterproof Endoscopic Camera is a great addition to any DIY toolkit. It’s super thin and flexible, sporting a 2 megapixel camera and an 8-way adjustable LED light. That makes it great for getting a glimpse into all sorts of dark, tough-to-reach spots. It’s also highly durable, and transmits everything it sees to your device via WiFi. So if you’re facing a clogged drain, an engine issue or just want to see what fell behind the desk, this camera can do the job.
