Raspberry Pi Camera
We're now offering this widely used mini camera-and-computer in a tiny box (the "Zero W" model) with a pre-flashed SD card that turns this into a ready-to-use WiFi enabled camera.
Just plug it in using a Micro USB cable (or battery pack) and it'll create a WiFi network called "00-PiCamera" -- password "publiclab" -- which you can log into from your phone or laptop. You'll quickly see streaming video, be able to take photos, timelapses, or videos, do motion triggered capture, and more.
Buy this kit and assemble the parts yourself (pretty easy) or pay $5 more to get it pre-assembled.
Includes SD card, 5MP camera, and power cable. Add on a lightweight battery pack for portable power!
