Bigger Boob Tube

Step 5 Focus the Image

The downside to this project is the fact that the CRT is not very bright. Most likely you will only be able to see the image at night, or in a room with no windows. You should turn the brightness setting in your TV all the way up. Some CRTs have screen and focus knobs within the case that you can twiddle. Physically moving the TV back and forth through the box can make the most difference, similar to the way you can use a magnifying glass to burn things. If you find just the right spot you will get the best results. If you have a white wall thats the best spot to project the image onto. I have mine set up so it projects directly onto the ceiling, and I lay in bed as I watch TV. I tried to take a picture of the image but it was too dark to be captured correctly. When I tried to up the exposure time the image became blurry to the point where it was pretty much just a square of light on my ceiling. So sorry no pictures :( Well I hope you enjoyed my very first instructable. If you have any improvements, comments, or questions I implore you to post them.

wouldn't the image be reversed?

Would you be able to make the projection come out the front of the box? if so, how?
