USB sticks have gotten so small that many people now carry them on a loop with their house keys. You can tote dozens of movies on these simple little gadgets, and soon a concept like the Keyring Camera might enable you to make your own as well.
While video cameras have decreased in size, they are largely too big to fit in your pocket and too delicate to carry without a case. The Keyring Camera project by Alex Trenear-Thomas takes portability and durability seriously with a design that seems impossible to break.
The Keyring Camera visibly comprises a lens, a microphone and a couple of buttons, with no display screen in sight and the rest of its components protected within a hard plastic case. Said case has been sculpted into a carabiner for handy attachment to your belt loop and keychain so you're reading to start recording anywhere.
