Check out Paul Beard‘s sweet DIY Holgaroid (Holga + Polaroid) made of the guts of a Polaroid EE100 and foamcore! He writes:
This project has been brewing for quite a while, but came to a full boil when I got gifted with a couple of boxes of Polapan from Bre Pettis, MAKEr extraordinaire.
The camera was a gift from him as well, and I have regretted disassembling it for quite some time (it worked fine but the pictures were pretty ordinary. So it got chopped up).
There are Polaroid backs for Holgas but they cost money, something I have very little of. I do have time and I’m not afraid to fail, so some foamcare, some glue, a fair amount of backing paper from 120 film rolls (not sticky or stretchy like tape, and it’s light-proof) and I made a box to put the lens at the right distance.
So far pictures have been tough to get, as the days have not been terribly bright and 80 ISO film @ 1/100 second is a bit challenging.
But I’ll get some.
