If you've ever had the idea of buy a projectorSurely you have noticed that, despite the fact that there are very good options at quite attractive and cheap prices, the truth is that in the end you need to connect them to a computer. It should be noted at this point that, in some of the cases, there are certain projectors that have a USB port from which they can read video and play it back.
Of course, the idea of a projector with the option of playing video or multimedia content directly from a pendrive or other type of external memory is really interesting, although, surely as good maker, you will want to give your project much more mobility and at this point is precisely where a simple Raspberry Pi can help us enormously.
Create your own smart project just by integrating a Raspberry Pi Zero to the system.
The idea that has moved the creator and developer user of this project is to literally get integrate a minicomputer within the projector itself. On this occasion and due to the scarce space available, the user has decided to integrate a Raspberry Pi Zero, although it is certain that, with another option, it could be possible to integrate a superior model in terms of connectivity and above all benefits.
As you can see in the video right at the beginning of the extended input, perhaps the most complex part of all is getting the projector modified to install a USB hub With which to expand the possibilities of the Raspberry Pi by adding several adapters where, as expected, Bluetooth and USB dongles are not lacking.
The final result of the entire project is simply amazing since it is possible to have in a fast and very simple way what we could call a computer equipped with a projector where there is room for all the operating systems you want to install depending on what you want to use your new smart system for.
