This is the most common type of projector that you can build yourself. This cardboard box phone projector doesn’t have the highest quality, but you can complete it for under $20!

Tools: Screwdriver
Difficulty Level: Medium

Consider this LCD projector if you want to build something with quality. There are many parts for the kit that you’ll need to order, but you should be able to get everything you need for less than $50.

Even better, when you’re done, you’ll have a projector that you can use for various occasions. While you’ll need various materials to build this projector, the only tool that you need is a screwdriver!

3. Mini Pocket Projector by raspberry pi

Materials: DLP2000 micromirror, raspberry pi, insulation tape, and audio device (optional)
Tools: Computer and soldering gun
Difficulty Level: High

There’s just something so appealing about having a compact projector. Having one that you built yourself makes it even better. This mini pocket projector is exactly that.

It’ll cost about $150 to get everything that you need, but you will get high-quality results with a projector that you can hook up just about anywhere. It’s a complicated setup, but there’s a comprehensive video that will walk you through everything that you need to do!

What Can I Use Instead of a Magnifying Glass?

Maybe you don’t have a magnifying glass on hand, or perhaps you want to try something different. While a magnifying glass is one of the easiest ways to make your own projector, it’s not the only way.

You can take a stab at making your own with a bottle of water and scissors. Don’t expect the same quality results, but sometimes, it’s simply fun to see what you can make out of different materials!

Can You Use a Sheet as a Projector Screen?

Sure! Ideally, you want a plain white sheet but gray can work too. You want to hang the sheet and try to get it as tight as possible for the best results.

You can also project directly onto a wall, and white or gray walls work best. It’s up to you how much effort you want to put into the screen and what level of results that you’ll be happy with.

How Can I Make a Full HD Projector at Home?

Yes, but the price is going to be much higher, and it’s going to take much more effort. Still, there’s no denying the high-quality results!

Whether it’s a projector or something simpler, making something yourself adds an extra element to the project that nothing else can match.
