How to project an image onto a wall? Closed

Question

Hello,I would like to project an image by enlarging it onto a big wall. However, I don't have a projector (and I can't afford one either). Do you have any ideas?

there is a projection tool that works with a lamp and mirrors that allows you to project the image of a paper support onto a wall. unfortunately, I can't remember the name. to dig...
otherwise, a slide projector remains the best equipment.

You rent a slide projector, or you put your photos in slides and place them in a projector.

Hi

A projector is not very complicated! It's just a few lenses and mirrors installed at the right angles.:

It's tedious, but the result is worth it!
On the drawing you want to enlarge, you need to find the center and cross a horizontal and a vertical line at that point. From this point, you need to create a grid of 1 cm square by drawing lines every centimeter vertically and horizontally.

You need to determine the enlargement of your drawing: 10 times bigger, 20 times.
Well, you need to create the same grid on the wall, with squares of 10 cm for 10 times bigger and squares of 20 cm for 20 times bigger. You can also make squares of 12, 13, 15, etc. However, you never change the measurements of the drawing to be enlarged.

Now that you are at this stage, you reproduce each square and your drawing on the squares on the wall and everything will enlarge. There you go, it's a lot of work. Good luck!!

Hi, I bought (cheaply) a kind of toy to project stars on a wall. Then I asked the person who prints photos from a non-digital camera to print the photos in the size I requested (very small), then I put them in my device and voilà. I recommend getting a toy and good quality batteries.
