I rigged up an assistive device.
An electronic magnifier that puts an image from a hand-held mouse-style camera on a (46 inch / 116cm on the diagonal) television screen.
Effective magnification is 20 times.
Magnifiers with small screens at high magnifications show only a small section of text.
My large screen allows multiple words & adjacent lines to be on the screen.
Orientation is easier to maintain.
Pics to come.

Anyone tried an hdmi industrial camera on a lever-arm stand with a suitable lens as an #ElectronicMagnifier - and the image displayed on a suitable tv / monitor?
I can see everything I want on aliexpress - except for the lens.
Which lens is going to let me view around a A4 / foolscap area?
Most of these setups are being used as microscopes with lenses giving around 150X magnification. Far too much for reading a book.
Assistance sought.

Have a cheap camera that is in a mouse-like case.
Connects to the VCR input on the 900mm/30" TV monitor.
Lets call it a mouse camera.
Need to change/modify the lens on the camera.
Need the camera to be in focus at twice the current distance. So ~ 80mm rather than 40mm.
Current lense is maybe 2.5mm diametre.
Expert opinions sought.
Ideas from non-experts too. 😁
