So a bit of a break from fixing computers. @rubber_jonnie had me interested in CRT TVs after not getting a great signal on one of his projects, so I decided to do a bit of Googling and ebaying and found a 4” mini crt for less than £20.

It actually peaked my interest because of the way is the CRT worked, essentially like one of those projection TVs maybe? The tube fires in at the bottom but displays a reasonable picture on the front, you’ll see what I mean in just a mo.

So a couple of pots, phono socket, power socket, bits a wire, a 12VDC power supply and a C64 later, we have:

A Sony Watchman?

More legible than trying to use a Sinclair flat screen telly. :-)

It’s from an old video intercom system I believe from doing a bit of googling.

That's a neat little thing, looks a lot smaller than my 5.5" B&W.

I seem to recall Adrian Black looked a a similar CRT not so long ago, I think he may have had a zap from the anode too!!!

Yes I’ve found his video but not watched it yet. I’m hoping not to have to venture close enough to get too many zaps :lol:

I watched Adrians video about this screen and it was quite informative, especially about picture adjustment, which I shall try out later on.

Oh and I've seen which bit not to remove, unless you like getting electric shocks :lol:
