Homemade DIY Beamer
In this post i will show you how i built my own OH-Beamer from an old computerscreen.
First i had to remove all the backlightning of the screen so that you're able to see through.
The next part was to install the screen and its driver and powersource on the OH-projector
After installing all the driverboard and powersource i had to build a cooling system in order to prevent the screen from getting damaged through the OH's lightsource.
Cool air gets sucked in at the front and flows under the screen right through the driver board.
Two pieces of  black felt decrease the stray ligth from the OH-projector.
Here a example of the image:
