Since high school (about 25 years ago) I have always wanted to make a CRT from a Vacuum Filtration Flask. After viewing Nyle Steiners project, I was inspired to give it a try. Below is a photo of the project and the link is to my youtube video of the same project.
Over the next several weeks, I plan on making a new electron gun with a more focused beam. Furthermore, the copper anode in the one pictured has caused a messy sputtering issue. Aluminum or stainless will be employed in the newer version.
Once done, the new video will have both deflection coils activated with a signal generator.
