This is a solargraphy camera I designed. The simplest of my designes, great for long exposures.

Dimensions and info:

• Designed for 240x180 mm paper sheets. I used Fomaspeed N311
• It's a panoramic camera — the paper bends in a half-cylinder, so the field of view is around 180° horizontally and 110° vertically. The focal length is fixed at roughly 76 mm
• The pinhole is located in the center of the flat front wall
• For pinhole you'll need a 45x45 mm piece of soda can metal and 4 M3 screws
• The lid uses 6 M4 screws. I recomend adding a layer of sealant on the lid surface to prevent water from getting inside.

All my pinhole cameras share the same pinhole frame and wall mount profiles

Feel free to use it!
