    Hi all,

    I've posted this here, because I feel it more electricity related than electronics.

    I'm trying to make a simple crt. At the moment, I've come up with this idea. My question is, is it likely to work? I'm not too sure, as there are a few components missing like the heater, but this is really just a 'proof of concept' design at the moment.

    Thanks,

    Sparky

    P.S. I am aware of the dangers of high voltage, I will be safe.

    Also, every existing design I have seen says that they have used aluminium as the cathode. Is there any reason for this? Does aluminium 'boil off' its electrons easier than other metals like copper?

    Many thanks,

    Sparky

    Yes I have, thank you Bertus.

    Unfortunately, it doesn't go into quite enough detail.

    Be careful that thing does not fill up with electrons!:)

    Sorry, but it just brought back memories.
