I've got nothing against home made stuff like this. People from an earlier
generation used to do that sort of thing quite often. It was also the way I
was brought up and I used to do stuff like that when I was a kid. They're
not as fashionable as they used to be but children's books, comics, and
annuals used to be full of things like this. Without it a lot of the
finished (and expensive) goods we take for granted today wouldn't exist.

I'll admit my Canon A590 isn't the greatest camera. I've spent a lot of time
taking a closer look at it and playing with CHDK raw, and its too small
sensor, soft lens, and JPEG processing could be bettered. But, I've learned
a lot about camera systems in the process and apart from that it's still a
great camera to learn the basics of photography.
