Re: [time-nuts] Lady Heather's Window, font size

2009-02-01 Thread Didier
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.

 O Nuts of Time,
 
 I was recently asked to make a big PDF file of the HP AC-4 counter 
 modules manual that I have had on my website for a few years as a 
 series of jpeg files. So I did...
 
 http://www.nixiebunny.com/hpac4/hpac4.pdf
 
 These modules are used in the ancient HP 521 to 524 series of 
 counters. Each module handles one digit. They have four vacuum tubes 
 and either a nixie tube or ten neons in a thermometer arrangement.
 
 I have a 521C and a 522B counter on hand but they are a bit too slow 
 to handle the 10 MHz of modern times, having a maximum counting 
 frequency of 200 kilocycles per second.

A pair of phantastron setups will divide it into range.
Should use up about 3 tubes.

Re: [time-nuts] Lady Heather's Window, font size

2009-02-01 Thread Didier
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.

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.

Thanks

[time-nuts] Some pics of the Datron 491x DC reference cell

2009-02-01 Thread wje
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

[time-nuts] Some pics of the Datron 491x DC reference cell

2009-02-01 Thread Mark Sims

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.   If you can live with that,  you can get a 
packaged 5V / 0.01% reference for $14.50 shipped...  see Ebay item 
250366551770...  the guy that builds them is closing them out...  and he ships 
worldwide.

Bill,

thank you very much for the schematics and the photographs!
Using XP / firefox, I was able to retrieve the files with the given 
special link, and also very easily with the FileZilla Client.

The most interesting part, i.e. the precision resistor circuitry, 
obviously resides on the bottom side of the ref board.

Would be great to get a photo also from that side, as Datron made some 
efforts to get rid of strain and heat conduction effects.

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.

When I used the first datasheet, I reversed the heater as there was no hint,

Yes but they didn't correct the negative reference circuit.
I notified them about that - maybe that will be corrected in the next
revision.

I've located my Vishay brochure on resistor networks from the 70's.
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

2009-02-01 Thread John Miles
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.)  Especially if you use it with /vs, the font
will appear much larger than it does in a window.

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.

I use the normal Win32 device-communications API (via CreateFile/ReadFile).
Same serial-interface module that I wrote to talk to Prologix GPIB-USB

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

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.

 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.   If you can live with that,  you can get a packaged  
 5V / 0.01% reference for $14.50 shipped...  see Ebay item  
 250366551770...  the guy that builds them is closing them out...   
 and he ships worldwide.

 Having failed to get the program working properly on an old 486  
 Laptop,
 I installed it on a more modern machine running XP. When I try to open
 the program I get an error message about Com Port Not Available ??

 How does one select the COM Port ?

 Thanks, Dick, W1KSZ
