Re: [time-nuts] Lady Heather's Window, font size
I have found it difficult to find out from within a Windows program how big or small a particular font is rendered. Windows has a function called TextWidth (and TextHeight) that does not work correctly for all fonts. It seems to be video card driver dependant too, as the same fonts look different (and have different size) on different video cards. I wrote a small VB program that you can use to find out if windows is lying for a particular font. It's at http://www.ko4bb.com/VB_Projects/TextWidth/TextWidth.exe This programs sets the size of the colored background to what windows says the font takes. You can see some fonts work well, and some don't. I have found that most of the time, Windows returns a size greater than is actually used. That can be useful if you use these functions by letting you choose fonts that work.

Re: [time-nuts] Lady Heather's Window, font size
Hi Brooke, Windows' error in the response to TextWidth is not a function of fixed versus proportional spacing, bitmap versus scalable font. I have not found a hard rule. Simpler fonts tend to be more accurately reported, but that's not universal. Experiment with my little program on different computers, you will be surprised of the differences. This came about because I tried to emulate a TTY screen and make the window exactly 80 characters wide, while offering the capability to change the size of the window. I have not been able to do what I wanted and at the end, I only selected one font which worked consistently over a few sizes, and I simply offer the user a few selections rather than let the user scale the window continuously.

Re: [time-nuts] Lady Heather's Window
Morning John, Just loaded up your build of Lady Heather on a XP Pro (SP3) machine. Runs just fine and the graphing is readable but the upper text portion is so tiny that it is un readable. Tried Brooks trick of changing the default DPI to 125 but it has no effect on the LH program. Any thoughts as to what I can do so I can read the text portions.

[time-nuts] Some pics of the Datron 491x DC reference cell
I've uploaded some photos of the Datron 10 volt cell and reference board, as requested by a few members. I've kept them full-resolution so you can see fine detail. But, that means they are about 3 mb each. The schematics for the cell board I previously posted are also still on the FTP site. DatronCell.jpg is an image of the entire cell board. The reference board is piggybacked on it. Note the thermal shield around the LTZ1000, and the completely shielded sections on the board. Those contain the digital circuitry. The cell board itself goes into a shielded enclosure along with the other three cells and the output buffer amp. DatronLTZCloseup.jpg is exactly that, a closeup of the LTZ with thermal shield removed. The interesting detail here is the mounting. Note the cutouts on the board to provide thermal isolation. This board is also very thin; I didn't measure it, but it's on the order of 0.5 - 1 mm thick. DatronRefCloseup.jpg is a closeup image of the rest of the reference board. The ref board is permanently soldered in place on the cell board, so I can't show the back of it. The ftp login is: ftp ftp.quackers.net login: f...@quackers.net password: (none required) Or, directly from a browser. I know this works for Firefox, I haven't tried it with anything else: ftp://f...@quackers.net:f...@ftp.quackers.net/ Some of you are also waiting for the schematic for the LTZ board itself; I'm recreating it now (since I lost it) and will post when ready. -- Bill Ezell -- They said 'Windows or better' so I used Linux. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
[time-nuts] Some pics of the Datron 491x DC reference cell
I tried to access the photos... got to an empty pub directory... Cutouts in a circuit board around a reference chip are usually more to relieve mechanical stress from the chip package caused by the PC board expanding/contracting/warping. This stress can affect the refereence voltage more than you might expect. Malone does this on his little Xicor X6008C voltage reference boards. (BTW that chip has been discontinued). That is why I prefer his boards over the other one that is available on Ebay that does not cut out around the ref chip.

Re: [time-nuts] Some pics of the Datron 491x DC reference cell
Bruce, good hint, I think you are right.. Then it's a custom specific R array, metal foil technolgy (S105 or similar) from Vishay, perhaps oil filled. Makes it very difficult to read the circuitry and design a replacement with discrete resistors.

Frank Frank The core circuit probably doesn't differ too much from the positive reference circuit shown on the LTZ1000 datasheet. It certainly wont be identical to the negative reference shown on that datasheet which has the heater pins reversed (as shown it will cause a large current to flow in the parasitic shunt diode connected across the heater resistor). NB use the latest datasheet which has a corrected schematic showing the location and polarity of the parasitic diodes.

The TO-5 can resistor networks used 50 mil x 50 mil (50mW) and or 150 mil x 50 mil (100mW) resistor chips wire bonded to the header pins. Either 8 pin(2 different pin circle diameter options) or 10 pin variants were available. Other than the resistor chip specifications (TCR, pwer dissipation, etc) there's not much else.

Re: [time-nuts] Lady Heather's Window
Ah, I should have mentioned that. You need to run it on a desktop that's at least one 'standard size' larger than the window, or my graphics library will halve the size of the window, which renders the text unreadable. The text is still pretty cramped when running normally, but it's not a standard Windows font -- it's a hardwired 8x8 raster font that's part of an ancient platform-independent graphics library I wrote back when the Win95 Chicago beta came out. So unfortunately there are no real options for improvement there without rewriting a bunch of code to use actual Windows fonts. One thing that would help is running it in fullscreen mode, which I forgot to enable. Grab the newest build at http://www.ke5fx.com/tbolt/setup.exe and add an -f option to your Windows shortcut if you want it to start in fullscreen mode (or just use alt-Enter or the maximize button to toggle fullscreen mode after running.)

Re: [time-nuts] Lady Heather Question
The DOS version had a bug that caused it to ignore the /2 altogether (it hardwired the COM port back to 1 after parsing the command-line arts). That's fixed in the Windows build. Mark: the Windows source code should still be able to compile for DOS at your end, if you change the #define back. If you'll switch to my copy (and switch to .cpp compilation) it would be easy to keep them in sync. -- john, KE5FX -Original Message- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com]on Behalf Of Magnus Danielson Sent: Sunday, February 01, 2009 2:31 PM To: Richard W.

Re: [time-nuts] Lady Heather Question
I use the normal Win32 device-communications API (via CreateFile/ReadFile). Same serial-interface module that I wrote to talk to Prologix GPIB-USB dongles.It should support any COM port number you give it. The graph ends up looking a lot neater with 10-second updates than with 1-second updates -- I wonder if that should be the default. The PPS and ref traces in particular seem to break up a lot at 1-second timescales. -- john, KE5FX -Original Message- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com]on Behalf Of Magnus Danielson Sent: Sunday, February 01, 2009 4:18 PM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] Lady Heather Question John Miles skrev: The DOS version had a bug that caused it to ignore the /2 altogether (it hardwired the COM port back to 1 after parsing the command-line args).

I think a more flexible fashion of setting size would be a good thing. The preferred fasion is always being able to do standard resize by dragging the edge, but saying x*y size at command line kind of works. Yep, the code could support arbitrary x*y sizes, but he has several groups of related parameters that are tied to the discrete size options -- and also, I can only go into fullscreen mode in standard VGA/EVGA resolutions. So I probably won't put a lot of work into that. Left as an exercise to the reader, as it were. If I hack Mark's code too extensively, it'll be hard to catch back up when he posts new updates. Avoiding the shrinking should be the main thing to do then, in this case it hurts more than it helps. Yes, that's true in all cases, really. It just confuses people. When I first wrote this code, there were some severe performance penalties associated with odd scale factors on many systems, so halving the window size in the event where the desktop area wasn't big enough to accommodate its client area seemed like a good idea. I also didn't want users running with a downsampled window without intending to, since that's like running an LCD at a resolution other than its native one, only worse. The half-size window is a pretty good clue that things are configured suboptimally. I'll probably just fix the problem with a readme file, since there aren't any easy hacks that work well in all cases where the desktop resolution is too small for the window. Forcing fullscreen mode in those cases would also be an option. Oh...
