DocuCam Laptop Document Camera
Have a webcam on your laptop?
Have, or have access to, a 3D printer?
Now you have a document camera for teaching!
Inspired by John Umekubo's pocket document camera, this holds a mirror to turn your laptop webcam into a document camera for teaching. This is a from-scratch customizer design that will let you adjust the mirror angle to fit, including temporarily flipping the mirror out of the way to use the webcam as a webcam.
Choose the size that best matches the thickness of your laptop monitor lid. For example, if your lid is about 6mm thick, choose
DocuCam-5-7.stl because 6 is between 5mm and 7mm. If you want to customize more, you can download DocuCam.scad and use the Customizer feature of OpenSCAD, or even modify the code and remix it into something new!
Not sure how thick your monitor lid is? Print the monitor lid gauge and slide it over your monitor. The number next to the smallest gap that fits is the best fit. For example, if that's the gap labeled "5", chose
DocuCam-4-6.stl to print.
You can also print the mirror holder (DocuCam-Mirror.stl) separately from any of the clip sizes (DocuCam-Clip-4-6.stl and so forth). (The mirror holder is the same in each of the complete sets.)
The only downside is that the mirrors are sold in sets of 60, so you really need to make lots of these and give them away to all the teachers you know who are desperate for a document camera.
What you show will be in mirror image unless you use some extra software. See John Umekubo's blog post for more information: https://johnumekubo.com/2020/09/07/the-pocket-document-camera/
If you have suggested improvements to the design, I'll be pleased to look at merge requests at https://gitlab.com/mcdanlj/docucam
