Here is an instructable that describes how it can be built: http://www.instructables.com/id/DIY-E...

This is my first attempt at building a cathode ray tube. I used a Viot VPD3 15 micron pump to evacuate a chamber made using a modified wine bottle. The power supply is a 9kV 30mA NST, the same one that I used in my spark gap Tesla coil. The dark band around the center of the tube is caused by sputtering of the electrodes.

This project is a replication of the work originally done here: http://www.youtube.com/watch?v=813-2a...

Thanks for all the support, guys! This project was featured on Slashgear, Engadget, Gizmodo, Gadgetblog, Tecmundo, Matuk, Zedomax DIY, and Make, as well as on instructables!
