$20 Document Camera

thingiverse

I'm a kindergarten teacher who's determined to crack the code of distance learning. To succeed, I need to stay connected to my students' work in real-time. That's why I'm eager to explore document cameras as a solution - they'll give me an unobstructed view of what my students are doing during our online classes. This print is made from PLA, a material that's easy on the budget and perfect for educational projects. One design centers around an HBV-1805 Camera module, which costs just $15. I labeled it as a 5MP case by mistake - the HBV actually has a resolution of 1MP. Despite this, it's plug-and-play, recognized by computers as a camera, and works seamlessly with Zoom. You can find this camera on Amazon at https://smile.amazon.com/gp/product/B07QV3PPTB/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1. I also designed another camera around the OV5640, which boasts a 5MP resolution and far better image quality. It costs approximately $30, including shipping from Bangood, and can be purchased at https://www.aliexpress.com/item/33044806307.html?spm=a2g0o.cart.0.0.777d3c00z3pXOz&mp=1. To assemble these cameras, you'll need a 2M x20mm bolt and a 2M nut, as well as a USB extension cord and a standard classroom whiteboard. Alternatively, you could opt for the laptop camera, which costs around $3 but has very low resolution. The .stl file for the laptop camera housing is listed above for your reference.
