Smartphones are fantastic tools for showing off our work, watching movies, or even playing games. Their “big” problem, though, is that their screens are rather small. This means if you want it bigger, you must connect it up to a TV or use a projector. Projectors for phones have been on the market now for a couple of years, but most of the decent ones are quite expensive. So, why not make your own?
This video from Matthew at DIY Perks shows us how to build our own “Ultimate Smartphone Projector” from scratch. Matthew first shows us a more traditional DIY smartphone projector. But that type of projector has some issues, which Matthew highlights. Those problems are solved with his rather ingenious periscope-style design.
