Medium Format Pinhole Lego Camera

After making the Lego conversion of my old Polaroid 95a, I decided to tackle another Lego challenge: a medium format Pinhole Lego Camera. I had several goals for the lego camera:
1. First, I wanted to make sure that the film advance knob only turned one direction.
2. Secondly, I wanted to have a film counter in addition to the red window.
3. And last but not least, it would be nice to have some sort of viewfinder.
Originally, I was going to build the camera in Lego Digital Designer, so I could share better instructions with the blogosphere. I still might do that, but until I get a computer that can run that software better, you will have to survive with just my photos. Let's get started...
Here is the main Lego Camera assembly:

There are a couple things to notice. First, notice that the top of this part is covered by the smooth sided Legos. This is done so that the lid of our camera doesn't stick to the "lid" we make later. Second, note the spring "shock absorber" at the top center. This piece pushes a block into the gear to keep it from turning backwards. There is only one piece that will have to be fabricated. There isn't a Lego piece that will fit perfectly in a 120 spool so we will have to fabricate our own. A Dremmel and some sand paper should do the trick. Here is the before and after photo:
This is the part that will be turning the spool.
Next, attach the following piece to the bottom of the assembly:

The two pieces at the bottom pivot to hold the medium format spools. The circle hole in the center is where our pinhole will be located.
Turning this piece over gives you a look at our shutter system. By moving the slider back and forth, we open and close the shutter. The animation below shows what I mean:

Here is what it looks like put together:

You can see that I lightproofed the inside, and added the pinhole.
Now it is time to build the lid of our lego camera. Nothing to fancy here:

You can see the red window as well as the top of the lid that has been light-proofed with tape. Here is the top view:

Now all that is left is to add some Lego Type to decorate it a bit:

This view gives you a better idea of how the film counter works. Basically, when you advance the film, this knob turns about an eighth of an inch. To make it accurate, I loaded the camera with film, and used the red window to see what frame I was on. As I got to a new frame, I marked the paper. It isn't completely accurate, but it is pretty close. There is always the red window if I want to double check. I also count the number of clicks from turning the knob. It takes about 23 clicks to advance one frame. You can see my viewfinder also from the last picture. Pretty basic: you just look through the hole and the square masks off an estimate of what you will be shooting towards.
I am hoping to post some photos from my first roll of film later on this week. Please let me know if you decide to build your own camera out of Legos, or if you have any questions about my design.

Please post some photos! This looks awesome! I still remember when I was a kid 30 years ago, I made a pinhole camera out of a milk carton. Way cool!

very nice indeed.. i’ll be interested in the pics.
i’ve begun to make a pinhole camera from hardening plasticine (polymer ‘clay’), but lego is cooler.

Very, very cool. So what if some people think it’s a waste of time? They probably spend their free time watching network television…
I built, demonstrated, and wrote up the principals behind a pinhole camera for my 8th grade science fair (about 30 years ago now). To my utter surprise, that simple project won third prize, and my little booth had three times as many visitors as I expected. I suspect that today (as 30 years ago) a lot of people treat cameras as “magic”; pinhole cameras are a terrific way to demystify photography and teach some elementary physics.
Plus, dammit, they’re fun.
Bravo.

Excellent hack! Pinhole cameras are still useful. A good pinhole camera can capture wide short focus shots that are not possible with a lens camera and the ghostly effect is an added bonus.

Thanks everybody for the positive feedback! I posted some photos from the first roll of film. Here are some links:

Wow, can I get a Leitz pinhole (20mm/1.0 Blummilux) lens to adapt onto one of these?
Fantastic job! Love the photos.

This is wonderful. I am blown away by your creativity and inventiveness. Thanks so much for sharing this creation. This is fantastic.
Posted by: David at October 10, 2005 01:45 PM
this is great. can you add length to the “lens”/bellows to play with zoom and focal length by adding legos to make a longer zoom lens?
this is a great project. drawings please…

hi! my boys and i love your camera and would like to try to build one, too. (my boys are 6 & 9 years old.) could you send a bit more detailed instructions about how you built the main assembly? (the boys are great at building bionicles & other legos and are awed by the idea of building a device like a camera.) thanks!

Betsy, I would love to help you out, but it will be a little while before I have more detailed instructions. If I knew this post would be getting the traffic it has, I would have made better instructions before I posted it. Anyway, tell your boys, that instructions are in the works. I bought my Lego collection at a garage sale for my son. He is only 2 now, but he will grow into them! In the meantime, I feel like a nine-old-again…

Hi, great stuff!! I have a photography class and our teacher said that we will later build a pinhole camera, so it will be a great time to put this in practice!
Oh, could you please put a isometric view of the fabricated piece, to make it easier to understand.

Posted by: danasaki at October 11, 2005 02:27 PM
I have read some of the conversations going on about this camera on other sites and have one point to make. It doesn’t really matter if the Lego people don’t want us to say Legos. The consumer decides the brand, not the company. Ask the experts. It is one of the first rules of branding. A company can do their best to influence the consumers perspective of the company, but in the end it is the public that makes the final decision. FedEx along with the brand guru’s at Landor realized this, and took advantage of it. It would have been silly for FedEx to try and insist that everyone call them Federal Express. Sorry if this is getting us off topic.
Now more on topic.
danaskai, Megapixels don’t really come into play here since this is film (medium format) and not digital. However … you should check out Adrian’s equally cool digital pinhole camera. As far as I know, it is the world’s first.

THIS CAMERA IS SOOOO FREAKEN COMPLICATED WAT THE HECK U EXPECT PEOPLE TO UNDERSTAND WAT EVER YOUR WRITING…..BAD BAD BAD U DON’T KNO HOW TO EXPLAIN PLEASE??????????

A quien le sobra tanto tiempo como para hacer estas cosas?? que me de un poco
Posted by: diseño paginas web at October 26, 2005 10:15 AM
I think that is Spanish for “Who has that much free time?” I get that a lot.
Cristal, Better instructions are on the way, but that isn’t going to make it much less complex. If you decide to tackle the project, I will try and help you as much as I can!
Francesco, I have thought about a 35mm version, but haven’t thought of a way to make it work yet. One of the challenges is the smaller size, because Legos are kind of clunky if you try to make something very small. I think it could be done, though.
Thanks everybody for your support and comments! I love hearing from you!
