postheadericon How-To: DSLR Pinhole Photography

We’ve featured our fair share of pinhole photography projects here at MAKE, and it’s no wonder. As complicated as cameras have become, it seems amazing that photos can be taken with something as simple as a tiny hole in a shoe box. But if you still yearn for all the creature comforts that a modern-day DSLR affords and you want to experiment with pinhole photography, you’re not out of luck. This quick hack turns your DSLR into a rather advanced pinhole camera.

You’ll need to use a spare camera body cap, which is normally meant for protecting the camera from foreign matter entering through the lens port when there’s no lens attached. If you always keep a lens on your SLR, you can use the body cap that came with your camera. But if you store your camera without a lens, you’ll probably want to pick up a spare. Luckily, they’re quite cheap. Simply cut a hole in the center of the body cap and tape a small piece of needle-pricked aluminum foil. The larger the hole is, the more light will hit your camera’s sensor. The tradeoff is that the picture will be more blurry.

Pinhole Photo
What’s great about DSLR pinhole photography is that you can combine it more easily with other photography techniques such as HDR or timelapse for an interesting effect. And if your DSLR supports video, you can even shoot pinhole video. If you shoot any cool photos with your pinhole DSLR, share them with the rest of us! Post them to the MAKE Flickr pool.

Join us Wednesday evening for the fifth episode of Make: Live, our streaming show and tell!

Make: Live 05 – Kinetic Contraptions
Wednesday March 23rd, 9pm ET/6pm PT
Watch at or on UStream
Please join us in the UStream chat or mark tweets with #makelive to interact live with the show.

We also give away a fabulous prize from Digi-Key to one chat member who can solve our photo challenge. We can’t wait to share some of the joy of making with you, live 2nd and 4th Wednesday of the month, on Make: Live.

Featuring the lovely and talented:

Evil Mad Scientist Laboratories – Tabletop Mechanical Pong
Lenore Edman and Windell Oskay show off their tabletop representation of the 1972 video game PONG. They challenged themselves to realize the properties of the game in a physical space using motors, solenoids, and other surplus parts. Discover the subtle nuances and smell the physics jokes by these prolific and delightful makers. Lenore and Windell are also on the MAKE technical advisory board.

Dustyn Roberts – Wind Lantern
Check out our visit with mechanical engineer and teacher Dustyn Roberts. She gives us a tour of the wind lantern, a turbine-powered LED mechanism and circuit from her book Making Things Move: DIY Mechanisms for Inventors, Hobbyists, and Artists.

postheadericon Collin’s Lab: Homebrew Piezo

Piezoelectric materials are about as close to magic as you can get. They turn physical pressure into electricity and can even turn electricity into physical pressure – an amazing sort of bidirectional converter for mechanical and electrical energies. Perhaps even more amazing is the fact that you can easily ‘grow’ your own piezoelectric crystals overnight using just a couple of common ingredients – awesome.

Ever since I made my first contact microphone, I’ve been amazed by piezos and their unique abilities. I was more than psyched to learn I could make my own piezoelectric crystals after finding recipes online. Now I just need to figure out how I’ll put these little guys to good use … feel free to leave any ideas/suggestions in the comments below!
