"Smartphone Projector 2.0" is a cardboard projector. You can magnify photos and videos on your smartphone up to 8 times and project them on a wall.


Brightness is not good because it is a type that does not use electricity. Also, of course, it is not equipped with a function to correct distortion during projection.


However, "Smartphone Projector 2.0" has the advantage of having a design like a retro projector or magic lantern. It's not suitable for important presentations at all, but in some cases it makes you feel better when you get together with your friends on holidays to see the photos. Also, if you project an old movie, you may be able to enjoy a certain atmosphere.


It's made of cardboard, light, and doesn't require a power source, so you can take it anywhere, but you need to maximize the brightness of your smartphone screen. Also, it is not clearly visible unless it is in a pitch-black place, so it is for people who can prepare such an environment.


It is sold on multiple sites including the developer, but only a few companies such as the British mail order site FIREBOX support delivery to Japan. The price at FIREBOX is £ 19.99. A separate shipping fee of £ 5.83 to Japan will be required.


The "Smartphone Projector 2.0" also has a set with speakers that runs on four AA batteries. It seems that it was made in response to the voice that it is difficult to hear the sound from the speaker when the smartphone is set in the projector. It's for people who want to watch videos and movies online.


Isn't it just a matter of using your own Bluetooth speaker? It's not surprising, but it may be a good option for those who want to stick to unifying the design.
