Re: [neonixie-l] Sperry radar clock now working!

2014-07-16 Thread Oscilloclock 
By "noise canceling", my crazy idea was something like this:

Attach a microphone on the transformer, apply a band-width filter at 900Hz, 
phase delay 180 degrees and output the amplified out-of-phase signal via a 
transducer or speaker mounted on the chassis.

Complete overkill, but could it possibly reduce a bit of the noise if the 
placement were just right?

Even when the laminations and windings are tight, magnetostriction
can produce a lot of sound. A 'varnished' transformer can be potted in
'rubber' to absorb the vibrations. Mounting requirements and wire
sizes are design issues.

 The 900 Hz noise of which Morris is mentioning is 'most likely' being

 caused by physical vibration of the lamination's within one or more
of 
 the transformers, and there is not much that can be done about it, if
I 
 am correct. But I'll wait and see along with the rest of us as to
what

Re: [neonixie-l] Sperry radar clock now working!

2014-07-15 Thread Morris Odell 


Thanks Tom,

The E1T clock is at:

https://www.youtube.com/watch?v=J5I_L4KY4Qo

The video doesn't show it well but there's a little IN-17 nixie on the 
front that displays the number of satellites seen by the internal GPS 
receiver. It was a nice technical challenge but to be honest I don't think 
it succeeds as a clock. We humans are over-experienced to recognise 
traditional clockfaces and digital displays without actively thinking about 
them. The E1T is too alien. Non-nerds don't recognise it instantly as a 
clock as they do all the others I've made and even when it's explained 
people don't see it as a practical clock. 

Thanks for the offer of the transformer varnish etc. I've got a couple of 
other avenues to try (not work related :-) but I might get back to you.

Cheers,

Morris

Thanks for the comment. It's hard to make the hands much thicker. It's
radially scanned from the centre out so adding more scan lines makes the

At the moment it's just 2 lines. I do increase the intensity for the minute

The hand could be several lines starting short getting longer then
shorter again?

Centrifuging could help with potting - ie bucket on a rope :-))

 

Maybe it is an excuse to try some active noise cancelling

Or, maybe you have had your fun and I'll give you two bob for it.

Hi Morris,

Yes I do, I follow you achievments with interest, where can I see pics of
the E1T clock?

Your display sounds complex, a thee phase scanning yoke! Why not just have
an X-Y vector display and drive that directly by the micro?

I do have a mate with a vacuum chamber (actually a commercial pressure
cooker with a vacuum pump) and I can get hold of some transformer varnish
as well. Want to give it a go? You have to bake it afterwards to get the
varnish to go off. Lot of work for a one off.

In your profession I would have thought that you would have access to a lab
with some sinister apparatus for preparation of "specimens" shall we
say...?

No it's a static yoke which is 3 phase delta wound and excited with 
suitable waveforms generated by a micro. It's the original 900 Hz radar 
power tranny that's the culprit.

BTW you may remember me as the fellow who once bought a E1T chassis from

Amazing!
Idea: Is it possible to give the hours hand a broader line?
 
I cannot wait to see extended technical information!

Hi all,


I've got the clock displaying time now. The video shows it upside down on
the bench so it's at a few minutes past 12. That howling power transformer
is a distraction, I'll have to wrap it in some sound absorbing material
especially as I like to add Westminster chimes to my clocks :-).

The next step is to put it all together and tidy it up!

Very nice Morris. The last display like this I saw had a rotating yoke with
slip rings, so if yours has one the power transformer must be a real
howler. It sounds like 400Hz too.

Can't wait to see it completed.
