Some people find a video camera on the door to be too imposing or intrusive. Instead, one Redditor made a “peephole camera” that looks through the little viewing hole of your door. He had a few specific reasons for making it:

  • “My daughter is too short to look through the hole unadded.”
  • “I travel and want to see who’s there.”
  • “I can now check the door when I’m on the can by using Tinycam Monitor on my phone.”

One of the most popular YouTube DIY-ers, Noe Ruiz, came up with a wearable Pi Zero camera, and showed how you can make it.

For the uninitiated, the Pi Zero is a $5 miniaturized version of the Raspberry Pi. It handles all the basic functions that a full-fledged Pi would. We already know that you can turn the Pi into a time-lapse photo rig How To Capture Time-Lapse Photography With Your Raspberry Pi and DSLR or USB Webcam How To Capture Time-Lapse Photography With Your Raspberry Pi and DSLR or USB Webcam Time-lapse photography can really give you a sense of how the world works on a macroscopic level, beyond anything conceivable to the normal human experience of time.

3. Car Dashboard Camera

A car dashboard cam, or “dashcam” for short, is one of the smartest investments you can make for your vehicle. It’s how you can back up what you say in court, not to mention a good way of reliving your road trips. But why buy one when you can make it yourself for a fraction of the cost?

Instructables user Vijay Guna made a smart dashcam that is completely automated. It switches on when you start the car, stops when you switch off the engine, and records videos in segments of 30 minutes. The videos are stored for a month, and then automatically purged. And you can check the footage at any time with an Android smartphone.

Vijay has step-by-step instructions for the whole setup, which shouldn’t cost you more than $100. It’ll probably be closer to $80. Of course, you can instead buy the right dashcam for you How To Choose The Right Dashcam For Your Car How To Choose The Right Dashcam For Your Car As you browse dashcams you may wonder why one would be desirable.

The glory days of the Polaroid are behind us, as we went digital. But we lost some of the charm along the way. You can’t take a photo, print it out immediately, and scribble a note on it. If you’ve ever got one of these, you’ll realize how precious they are. Here’s how to get that magic back.

Raspberry Pi Camera Instant Polaroid

One genius hooked up a Raspberry Pi, the Pi camera module, and a thermal printer. The end result is an instant camera much like Polaroid.

It’s one of the coolest Pi camera-based projects we have seen, with real practical utility. You’ll need some specific materials for this one, like a box that uses a simple latching mechanism and has hinges on the outside. You’ll also need Adafruit’s lock solenoid, along with other items specified in the full guide. But put everything together and you have the most secure treasure box that no one but you can open.
