The complete hardware foundation of our Paper-7 picture frame is now openly available on GitHub:
github.com/paperlesspaper/paperlesspaper-hardware
So if you've always wanted to know what the frame looks like from the inside, or if you want to build your own e-paper picture frame: This is your starting point.
Releasing software as open source is now standard. With hardware, it is still very rare, especially when it comes to complete consumer products.

For us, a few things go together:
That's why you'll find the real CAD sources and also the fixtures we use for assembly in the repo.
Details will be continuously updated here:GitHub
You can open, edit, and export all Autodesk Fusion 360 files for your own manufacturing..f3z-files.
For construction, you need a 3D printer for the battery compartment, USB holder, and spacers, and preferably a laser cutter or CNC router for the back of the picture frame (or whatever you attach to the back).
As a frame, you can use a standard picture frame with spring clips or, of course, a completely custom design.
A few ideas of what you can do with the files:
Different types of wood, different sizes, different shapes. The main thing is that the interior fits in.
If you want to display other formats (e.g., 4:3 graphics or special layouts), you can adjust the mat.
The setup is suitable for universities, maker spaces, and workshops to demonstrate Low-Power-IoT + ePaper on a real product.
But also a very honest warning: Unfortunately, this is not a "download STL once and finish in 10 minutes" project, but there will certainly be instructions in the future.
