This is a hacker made in the hacker space in Cairo.
We need a projector in hacker space for Internet of Things build nights and other workshops, classes, and Friday night of hacker movies.
The problem is that we can't afford to buy a real projector, so we did our last "Hacker Scout campaign" at the second-hand Friday market in Egypt, and we found a DIA projector 40 years ago, it was made in western Germany! ! ! .
We bought it for 100 Egyptian pounds = $14.
Here is the list of parts I use in this hack: * any DIA projector should work.
* Any cracked display should work.
* Any device that can display data on the screen you use can work properly.
This step is not difficult, but be careful that it has a tricky part.
Technical Description: all LCD/TFT displays are actually transparent! !
Yes, your phone, laptop, TV screen is just a clear glass and the data is displayed inside.
What makes the screen opaque when you look, because it has some sort of shell made up of multiple parts
Install a layer of plastic lens and metal cover on the back of each LCD screen of any device.
The lens on the back of the screen reflects and concentrates the white LED light from the bottom of the screen to the entire surface of the screen, which makes the data displayed on the LCD visible and readable to the human eye.
Note: Be very careful and gentle when using a brown flexible connector. (
Do not make any adjustments)
Be very careful about the screen itself, and be careful about the pressure of your hands when hacking.
After opening the metal back cover, most things will start falling by themselves and don't force anything.
Step: This monitor I am using has an NTSC/pal TV drive that can be connected to the TV video output connector "yellow connector.
I used the composite video cable used with the Nokia N900 smartphone and Raspberry pi.
Connect the black and reading wires to 12VDC and ground through the adapter.
When the display lights up and starts to display normally, make sure it is transparent and all the useless things will fall off at the back.
I was lucky because the projector halogen light was working and very bright.
Prepare the area where the screen will enter and make sure there is a space for the screen, cable and drive board.
It's easy to know the best place to place the screen, just put it in the same place as the old slide input.
First, enter the screen carefully in the slide hole.
Next connect the yellow video connector and then power on.
After completing all the above steps, turn on the power and you should see the screen LED lens on and you will see the data on the screen.
Make sure the screen is not flipped vertically or horizontally.
Adjust the brightness of the LCD and the brightness of the projector lamp.
Adjust the projector lens focus for the best results.
Resize the screen from the device.
Note: all these photos were taken with room lights on.
