DIY peephole cameras and wearable timelapse recorders, anyone?

The Raspberry Pi is one of the most versatile gadgets around
— hands down.
You can use this single-board computer to make a full PC or something as strange
as an internet-controlled
car horn
. Really, the more you play with it, the more you discover. For
example, with the Raspberry Pi camera module, which is available for all
versions of Pi, you can get to work on a number of creations. Below are four
bizarre but useful Pi camera projects that are useful and simple to

Peephole camera


You want to keep your home secure, and may even go to
extremes with that, but chances are, most people would find a video camera on
your door to be too intrusive. So what’s the alternative? A DIY Raspberry Pi
peephole camera, of course. This is a great project if you travel often and
want to check up on your property, or if someone approaches your door while you
can’t answer it.

Surprisingly easy, this is a great way to start
experimenting with your Pi’s camera. Raspberry Pi aside, you’ll need an 8 GB
memory card, a Pi camera module, and a few cables to connect the power and so
on. Fortunately, this camera uses one of the most popular guides to make an HD
video surveillance camera, designed by Christoph
, which you’ll find referenced in many Pi camera experiments.

Car dashboard camera

A car dashboard camera, also known as a “dashcam” for short,
is a smart investment for your vehicle. You can use it to backup what you want
to say in court if needed, and you can also relive some of those awe-inspiring
road trips you might have taken. The best part: you don’t have to buy one, but
can make your own for a fraction of the cost.

Instructables user Vijay Guna, for example, created a smart
dashcam that’s completely automated. It switches on when you start your car,
stops when your switch off the engine, and records videos in segments of 30
minutes. The videos are stored for a month and then automatically purged.
Better yet, you can check the footage anytime with an Android smartphone.

The project shouldn’t cost more than $100, and you can see
the step-by-step instructions here.

Wearable timelapse

Thanks to today’s technology, you can record your life and
log every aspect of it if you so wish, and the cheapest way to get started with
it is through a Pi camera setup. One popular DIY-er, Noe Ruiz, came up with a
wearable Pi Zero camera, and you can see how to make it in the video below.

If you’re not familiar, the Pi Zero is a $5 miniaturized
version of the Raspberry Pi. It handles all the basic functions that a
full-fledged Pi would.

Instant Polaroid-like


The days of the Polaroid are in the past, but you can’t
argue against the fact that some of the charm of picture-taking was lost once
we went digital. These days we rarely snap photos to print out, jot notes on,
and send on their way.

With a bit of magic, also known as a Raspberry Pi, the Pi
camera module, some cardboard, and a thermal printer, you can make the art of photography
personal again. Of course, a thermal printer doesn’t use the same quality of
photo paper or have the same quality of printing, but it’s good enough when you
consider it’s printed out almost immediately. See the original instructions here.
