[time-nuts] WOT: Identify this movie

2012-09-25 Thread Bill Hawkins
It's a dark and quiet night, and list traffic is way down, so please
forgive
me for this way off topic request. I'm writing a book about automation
and
have a chapter on the future thereof.

I have a dim memory of a TV show or movie in black and white that has
the
teeming billions of earth living in high-rise buildings, each in a self-
contained room. Occasionally, they work by pedaling a machine that
generates electricity for the tower. Their leader exorts them to work
harder through a wall-sized TV set.

Does anybody recognize that scenario? At least one writer has suggested
welfare dormitories for the 50% of workers made redundant by
automation
around 2050. Would like to get it into the book if I had a reference.

Note the use of a time in the future to stay near topic.

Are you sure it is fiction? It sounds like the only place Lance Armstrong will 
be allowed to ride his bike in 2050.

Bill,

Seems to me the movie Fifth Element had some kind of living quarters similar 
to
what you are suggesting sans the bicycle thing.

Re: [time-nuts] WOT: Identify this movie

2012-09-25 Thread GandalfG8
Not sure about your film reference but a Google search on humans pedal to  
generate electricity provides some 200,000 replies with quite a few 
indicating  this is already being done, albeit on a smaller scale, from 
locations 
such as a  Danish Hotel to Brazillian prisons, and with commercial and DIY 
projects aimed  at individuals also available.
 
It seems to be quite a common theme in fiction too so perhaps your film is  
somewhere in those results but I don't have time, spot the doomed  attempt 
to keep at least vaguely on-topic again:-), to check them  all.
 
Amongst plenty of other works of fiction that include this  concept as part 
of the plot, and the IMDB does indicate this one  to be a work in progress 
as far as a proposed film is concerned, is  a book entitled Go-Go Girls of 
the Apocalypse.
Whether or not the work itself is worthy of any consideration whatsoever I  
have no idea, but it deserves an award just for the  title:-)

Sounds like the OP's story was from Harry Harrison's nightmarish novel of

Incidentally I do not know the Lovecraft story mentioned below, do you have
a title? A circular rotating prison sounds like a nightmare from the 20th
century's other great fantasist Borges, who also wrote stories where time
was twisted and stopped, to remain true to the list :)

Hi

I suspect it's going to have the same issues as other ion trap standards.
The first one that usually pops up is the need to cool the walls of the
cavity to absolute zero, so stray heat doesn't speed things up.

[time-nuts] Question on OSA8600 Oscillators

2012-09-25 Thread Ulrich Bangert
Gentlemen,

I have currently two OSA 8600 in my house for testing purposes. One of them
says VAR 02 on the label and has an explanation of the pinning of the
D-Sub connector on it. I wired a cable with that pinning and made my the
first measurements with this oscillator. 

The second oscillator says VAR 60 and is different from the first in that
the enclosure is abt. 2 longer than the first one due too an additional
piece of tubing that is connected with some screws to the original body
which is the same size as the first oscillator. When I connect my cable to
the second oscillator it draws no current from the power supply and no
output signal is available. Does anyone of you have the pinning for the
second type of OSA 8600 available?

The serial # is 822, the supply voltage is 24V and there is additional
information on the label saying

A0320666

and

QNM 58A

which I am not aware for what it stands for.

Thanks in advance for your help

Re: [time-nuts] Question on OSA8600 Oscillators

2012-09-25 Thread Tom Knox

Hi Ulrich;

It was to adapt the BVA to a telecom system. I cannot remember the exact
 pin out. You can easily check by removing that extension. It houses a 
POT and the DB9 to DB9 crossover wiring adapter. You can then see the 
correct pinout since the internal DB9 connector on the main BVA is 
conventionally wired. Email of call if I can be of more help.

Best Wishes;

Hi

So now the question becomes, how well can you track the 100ms after the
second point that the phase reverses? Put another way: How fast do they
*really* invert the phase?

Hi

Given the low frequency, it's not to hard or expensive to do a DSP radio. A 
true FPGA (not a CPLD) would do it pretty easily. You could probably do it with 
a reasonably fast micro controller.  Normally the ADC would be a significant 
chunk of the cost. At 60 KHz … not so much.

There is indeed additional detail in the spec that we had not seen. So I
will do some reading tonight.
However I am still working on the d-psk-r and at least at this point may
have a mod that works. It does on my local home brew bpsk generator even
when I add a great deal of noise. Though the noise added is really a flat
noise nothing like the ugly stuff on 60 KHz with impulse and such. But what
I have is not a very generalized approach.
Whats very interesting and others have mentioned there can be some very
creative ways to approach the BPSK if all you are interested in is getting
rid of the BPSK. You can down convert the signal and sample on a sound card
using tools like Spectrum Lab. Talk about a sledge hammer approach. Its
pretty interesting.
But like you I am curious is there a chip set that does the magic available
from DigiKey for $3.95? Would hope that what ever comes out might have a
phase control signal. Or does this cost an arm and a leg?

Paul,

http://www.xtendwave.com/ is a little bare.  The only mention
they have of the product is:

http://www.xtendwave.com/EverSet.pdf

It does not appear that they have a shipping product today.

I'm not really clear on why it's necessary to change the
modulation before the chipset is even on the market, but that seems to
be the way it is.

Various patent searches haven't turned up much, either, but I
could be missing something.

As for an FOIA request, if someone's going to file one, I'd be 
happy to chip in towards any duplicating fees.  I can also scan
documents if needed.

Hi

As long as you deal with straight overload, an ADC based receiver doesn't need 
as much front end selectivity as you might think. A fairly simple L/C filter 
should be plenty. A tuned antenna probably is going to provide all the 
selectivity you'd need.

[time-nuts] Low power timekeeping

2012-09-25 Thread Hal Murray

I've seen at least one good web site out there discussing pedaling to 
generate electricity for home use.  Here is an example I like:
  Pedal Power Generator - Electricity From Exercise
  http://www.los-gatos.ca.us/davidbu/pedgen.html

But this is time nuts.  Has anybody looked into low powered sources of 
time/frequency?  What would a time-nut do if living off-grid?  (Or just being 
a nut and going for low power?)

Ballpark for a bicycle is 100 watts.  If you do that for an hour a day, you 
get 4 watts averaged over 24 hours.  You could double that by working harder 
or longer, but 10x gets tough.

If I did the math right, tvb's numbers say a TBolt takes 3.25 watts (after 
warmup)
  http://www.leapsecond.com/pages/tbolt/power.htm
That doesn't leave much leftover for lights and such.

How good a clock could you get at much lower power?  I guess I'm looking for 
something (logarithmically) between a watch and a GPSDO.


Solar is another possibility.  I think that just turns into how much space you 
have and/or how much you are willing to spend for solar panels.  (and where you 
live)

Hal,

The Csac takes 115mW, and a good GPS takes another 100mW or so.

The Csac has a 1pps input for primitive disciplining from the GPS.

Turning on the GPS for 5 minutes every hour gives about 150mW total consumption 
with supply losses.

Can't get more stability than that for less power anywhere.

Re: [time-nuts] WWVB PM Receiver

2012-09-25 Thread Gregory Muir
I have had a neat little WWVB receiver hanging around the lab that was made by 
a now defunct company called Elemek out of East Syracuse, New York.  It was 
manufactured in 1979 and consists of a handful of discrete components for the 
RF front end followed by simple CMOS logic and a few analog op amps to provide 
a buffered 60 kHz carrier output, a 100 kHz square wave phase locked to the 
WWVB carrier plus demodulated WWVB time code.

The whole unit is about the size of a loaf of bread and requires 12V at 30 mA 
for operation.  It is quite an interesting design.

This company was in the business of contract development and design services.  
They did some unusual work in the form of an electronic stencil maker, the 
world's first electronic ski binding (!) and a work crew availability status 
system.  I think I see why they disappeared.

The trick to ultra-low power, I think, is to not run the GPS receiver full
time.  If you literally want something between a wrist watch and a GPSDO
then build a GPS disciplined wrist watch GPSDWW.  Let the watch run open
loop until  say an hour then turn on the GPS for a few seconds, adjust the
watch then power off the GPS.   Likely you'd use something better then a
watch crystal but almost as low power

Rather then spend a lot of energy with a heater and oven to stabilize the
temperature I think you can dig a deep hole in the ground like a well and
burry the oscillator and have an ultra stabile temperature for years.
