Warning - geek alert. The oscilloscope clock

Post by 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 :lol:



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

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

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 :-D

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 :rofl2:

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.

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?

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

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.
