Step 4Making the frame
Because all overhead projectors and screens got different sizes are there many ways to make a frame. I'll give here some tips:
1) Important is the cooling of the screen. Create enough space between the LCD screen and the glass plate (between 6-8cm). In my design I placed at the left and right side a 80x80mm cooling fan. To create a good airflow, one will blow in and the other blow out.
2) Make the screen hole in the middle.
3) Think about where you can place the power supply, LCD controller and OSD controller.
4) Paint it a nice color.
5) To improve the light reflection place some aluminum foil inside.
6) I placed some gaffer tape on the edges of the screen hole to protect the LCD screen.
7) Place the cooling fans on the frame and connect these wires together.

Looks like a standard fan that you get with most computers.
What power supply did you connect to? Does the power comes from the LCD display or the mains? Could you perhaps show me a photo?
Where did you place the powersupply for the lcd? Difficult to track in the photos.
I have peeled ;) the lcd monitor. Yes, successfully. Tested the lcd on the projector and it works.
I now need to make a frame and get a blackout cloth for the screen.
thanks
