[time-nuts] WOT: Identify this movie
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.

Re: [time-nuts] WOT: Identify this movie
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:-) Regards Nigel GM8PZR In a message dated 25/09/2012 07:05:55 GMT Daylight Time, b...@iaxs.net writes: It's a dark and quiet night, and list traffic is way down, so please forgive me for this way off topic request.

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.

Re: [time-nuts] Question on OSA8600 Oscillators
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.

Re: [time-nuts] WWVB PM Receiver
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.

Re: [time-nuts] WWVB PM Receiver
Brooke 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? Regards Paul WB8TSL On Tue, Sep 25, 2012 at 5:18 PM, Brooke Clarke bro...@pacific.net wrote: Hi: So how do we make a receiver to decode the PM format?

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.

Re: [time-nuts] WWVB PM Receiver
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
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) -- These are my opinions.

Re: [time-nuts] Low power timekeeping
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
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.

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.
