Warning - geek alert. The oscilloscope clock

[bobins]

Absolutely nothing to do with French cars, but.......
I'm sure there are one or two people on here that'll be interested in this



I've absolutely no connection with the project, but it does look rather nice

I've supported a few projects on Kickstarter, but sadly this clock is a bit big for the bedside table

That's a very nice clock.

I built one of these a few years ago:



It took a few hours of soldering but worth it.

I've wanted a 'flap clock' (the sort you used to see in banks) for a while; but I like the look of those oscilloscope clocks a lot!

Very retro Elis - I do like that - especially the way you have managed to hide the 5 suitcases carrying the batteries

Just kidding - I think it is great and would go well with my collection of Lava lamps, Plasma Globes, Air Clocks, Borg Lumin Glass and 3D Star Trek mirror!

Haha, I did experiment running it off a small 3Ah lead acid, but it went flat overnight. If you do get one, I highly recommend the case as there area few terminals live at 170V to drive the discharge tubes and they can give you a bit of a nip if you happen to accidentally short them out

The clock kit I built made use of Russian Ni-8 tubes (IIRC). I accidentally bust one of them so I bought a spare set as they are becoming harder to find, not sure if there are many about now.

Someone on autoshite has just bought a boatload from Russia - some miniature ones to make a watch with too.

We own up to having one of these - bought from Habitat, somewhere in the 80s

Not really 'bedside' - it's about 42cm square!

You could do a miniature bedside one using a 1CP1 - I should imagine that there are still some around if you search.

That's a nice clock! definitely need to get myself one of those at some point!

I Don't know much about analogue CRT electronics, but is there ant reason you couldn't use a large CRT from a scrap TV, or do they have to be these specialized small CRT units?

[white exec]

Careful with those CRTs - Nothing like a dose of x-rays next to the bed?

[GiveMeABreak]

True, these days I have my Apple Watch for my alarm clock in bedside mode and frequently change the watch face so never get bored.

There's a difference in the way in which the beam is deflected - the 'scope' CRTs are electrostatic, the TV ones electromagnetic.
It could in principle be done, but it would be much easier to use a Raspberry Pi or the like to display the clock on a raster, per standard TV / monitor practice.
