Jim K writes in to share this fun-looking project, a DIY handheld projector. Similar to the larger homebrew video projectors we have covered in the past, this one uses the screen from a portable TV screen to make a handheld micro projector. It probably won’t nearly as bright or sharp as a commercial one, but it looks like a ton of fun to make, and I can think of all sorts of awesome things to do with a handheld projector that could be stashed in a backpack…

Before anyone complains about the image quality the device produces, please allow me to say that I own that model of Casio TV, and I do believe Jim K’s results look about 10x as good as the stock display’s!
I tried to make one of these. Finding a good, even light source is very difficult. Using a flashlight like that is terrible, it gives very poor results.
I had a Sony Watchman back in the 80s. I was playing with a big ‘ol 4″ lens unit from some sort of projector. When I positioned it in front of the watchman in a dark room, the image projected on the wall. So I made a stand for it on my nightstand with the Watchman facing upward and the lens above it perfectly distanced to have a crisp large image on the ceiling in a dark room before bed. Sure beat trying to watch a TV on a dresser.
I like to physically carry a means of projecting- further democratization of access to display of media.
The fourth image is from the BBC comedy series Yes, Prime Minister and is of the Honorable James Hacker played by the brilliant Paul Eddington.
Gotta love a good image pun…
