Homemade DIY BeamerIn 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.
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.
