This is a magnifier based on a webcam and a tablet.
You need:
- A tablet (only tested on Android)
- A webcam “Razer Kiyo” or “Angetube Webcam 967”
- An OTG adapter to connect the webcam to the tablet
- A photo camera screw (0.25" / 20tpi) 15mm long (Optional as one printable model is provided. but printed screws are fragile) if you choose “Razer Kiyo”
- A M5x30 screw
- Two M5 nut
The Razer Kiyo is a good camera for the job as there is a ring lightning that keeps the text to read clear in many conditions from low lightning in winter to high reflection in summer.
But it has compatibility issues with some tablets. I found the Angetube Webcam 967 working with more older devices like the Samsung Galaxy View (18.1").
Printing other people models always struggle when you have to source the proper hardware. Let me know if you want other dimensions for the screws.
You also need an app on the tablet allowing you to manually adjust the focus. Autofocus is not confortable. I tested “USB Camera Standard” from Infinitegra on Android. By adjusting the height of the camera, you change the field of view then the magnification factor. If you adjust the height, you then have to adjust the focus on the webcam again through the App on the tablet.
