Now. A dumb question... do I just copy this to the \Windows\Fonts
directory, or is some other step required?

Now. A dumb question... do I just copy this to the \Windows\Fonts
directory, or is some other step required?

I think I just copied it into the folder that is shown when you follow
Start -- Settings -- Control Panel -- Fonts
but maybe it must also be registered.

See also:

http://support.microsoft.com/kb/314960

Adding New Fonts
----------------
Windows supports TrueType fonts or fonts that are specially designed for
Windows, and these fonts are available commercially. Some programs also
include special fonts that are installed as part of the program
installation. Additionally, printers frequently come with TrueType or
special Windows fonts. Follow the directions that come with these products
to install these fonts.

To manually install or re-install a font:
1. Click Start, and then click Run.
2. Type %windir%\fonts, and then click OK.
3. On the File menu, click Install New Font.
4. In the Drives box, click the drive that has the floppy or CD-ROM
that contains the fonts you want to add. If you are installing fonts from a
floppy disk, this is typically drive A or drive B. If you are installing the
fonts from a compact disc, your CD-ROM drive is typically drive D.
Double-click the folder that contains the fonts.
5. Click the font you want to add. To select more than one font at a
time, press and hold down the CTRL key while you click each font.
6. Click to select the Copy Fonts To Fonts Folder check box. The
Windows\Fonts folder is where the fonts that are included with Windows are
stored.
7. Click OK.

Note On Microsoft Windows NT 4.0, Microsoft Windows 2000, Microsoft Windows
XP, and Microsoft Windows Server 2003, you must be an administrator to add
and remove fonts.

Arie's hint is great. But it'll be lots of typing. If it isn't for doc
purposes but just for mutual understanding there is an easier way. This
Saturday me and my layouter (with him being in Vermont) just could not
get onto the same page with a weird kind of laser diode mounting
(z-bend, then rotate a bit and lay flat over some discretes).

So I sketched it up, scanned that in and zipped it over. Tada! Problem
solved, layout is now done. But the fab people haven't come back with a
quote for hours now. Hope that doesn't spell trouble.

I really like the scanner. Got myself one of those biz-hub style things

Nothing works like quadrille paper, pencil, eraser, ruler and eraser
shield until you get the concept settled. Then, and only then, is CAD
productive, IMHO.


Agree. Except that I don't know what an eraser shield is. Do I have to
feel dprived now?

It's handy effectively having a photocopier within reach too (scan
directly to laser printer). I use it rarely, but it sure comes in
handy when it's needed.


Yep, it does that, too. Just have to hit another button and it copies.
Faxes, scans, prints and copies at a pretty good clip. This has freed up
a lot of space in my office plus I have better redundancy now. It has so
many buttons that I just discovered a new one after over a year: It can
scale copies. Yeehaw. Didn't know that.

An eraser shield is a small piece of stainless steel, about the size of a
credit card and very (0.010" or so) thin. It has various size cutouts in
the steel, some circles, some radiuses, some straight lines, some !
teardrops, etc.. You put the shield over the part you want to erase a tiny
portion of and erase like hell without worry about erasing too much.

I've still got a working electric eraser (both plug-in and cordless) if
anybody needs one. Otherwise they go to the engineering museum when I kick
off.

Nah, that was Teledeltos paper. It was electrically conductive, with a
sheet resistance of something like 10k ohms per square. You cut it with
an X-Acto knife, put a voltage across it, and it solved the 2D Laplace
equation for voltage drop vs position pretty well. I went looking for
some a few years ago--it had been picked up by a British outfit,
allegedly, but they didn't seem to have any for sale any more.

Thanks for explaining. Didn't know that. But I could imagine that the
sharp edges will increase the amount of eraser turds that go all over
the place, where my wife says "look at the mess you made now".

At the university we were forced to use ink pens. The tricky ones from
Rotring or Staedtler that would only work if held at exactly 90 degrees
to the vellum, would leak a lot and dry up in no time. Plus ruin the
occasional shirt. Same during the internships that were mandatory. So
yeah, I kind of got used to that.

Whenever I was working up that uppity genius feeling gravity struck.
There have been times where I had to use a razor blade more than once in
the same spot. The first instance could be somewhat muffled by rubbing a
fingernail over it but the 2nd razor application definitely showed. By
the 3rd there was a hole...

The ME guys had some kind of "cheat vellum" where you could peel off a
layer and it almost looked as if nothing ever happened. Very expensive
though but it did prevent the ink from frazzling out too much. Somehow
many of them had more money than us EEs.

Nothing works like quadrille paper, pencil, eraser, ruler and eraser
shield until you get the concept settled. Then, and only then, is CAD
productive, IMHO.


Agree. Except that I don't know what an eraser shield is. Do I have to
feel dprived now?

LOL, on the contrary, if you don't know what an eraser shield is you
must be a genius working with India ink from the start.


At the university we were forced to use ink pens. The tricky ones from
Rotring or Staedtler that would only work if held at exactly 90 degrees
to the vellum, would leak a lot and dry up in no time. Plus ruin the
occasional shirt. Same during the internships that were mandatory. So
yeah, I kind of got used to that.

I was just kidding, and I wasn't referring to formal drafting. The
premise was that if you can do logic design with an ink pen (ergo,
no easy erasure available) then you must be able to get it right the
first time out, ergo you must be a genius.

There have been times where I had to use a razor blade more than once in

layer and it almost looked as if nothing ever happened. Very expensive
though but it did prevent the ink from frazzling out too much. Somehow
many of them had more money than us EEs.

There's a lot to be said for sketching things freehand. Particularly if
one is a visual/spatial thinker, it helps with the conceptualization
process.

Some years ago, I was responsible for maintaining a rather complex
engineering document management an configuration control system (built
in house). All of the diagrams in my documentation were done by hand on
quad ruled paper. From time to time, management required that an
'official' version be done by the CAD group, but I came to find out that
the IT folks had taken to distributing copies of my drawings to the
various support groups and shelving the CAD versions.

One (new) manager had requested that the CAD group produce an overview
data flow diagram by combining all the individual diagram pages into a
single sheet. It was about 36x48 inches with small (10pt) font labels
and symbols. The story was that as soon as he saw the system he was to
take responsibility for on one page, he quit.

My drawings were 8.5 x 11 sheets with each sheet being the data flow or
E-R for a single event (weekly backup, new version checkout, etc.)
making the system a lot easier to comprehend.

What's that round thing in the top slot, a drop of solder flux?

Here's a photo of the kind of thing:
http://www.danielsmith.com/products~...24+090+010.asp

It's also an inexpensive source of small bits of SS shim stock. ;-)

Hmmm. speaking of solder, Digikey seems to have jacked up their prices
of 63/37 Kester '44' to *double* that of Mouser ($28/lb rather than
$14/lb). Seems a bit much.

Thanks, Arie. Just tried it in MS-Word. Works nicely. Just in case someone
wonders: It doesn't show up as XWave but just two brackets in the font
list, way at the end.


Normally that can be cured using
On the Tools menu, click Customize.
Click the Options tab.
Select or clear the "List font names in their font" check box.

Also, when an administrator installs the font while a user is logged in, the
user cannot use it (Office does not show it) until the user logs out and in
again.

Probably an RoHS thing. As I recall, if they allow *any* lead into their
building, everything they sell is suspect for having lead contamination.

RoHS manufacturers have to be very careful to not allow lead in their
doors.

Absurd.

Many mil contractors are exempt and have both technologies in house at
any given time, and nobody is so retarded as to say that one contaminates
the other.

There is a package for Linux.
"This software package provides a command line tool for documenting hardware
and software designs through timing diagrams. It reads signal descriptions
from a text file with an intuitive syntax, and outputs a timing diagram to
an image file. Notation typical of timing diagrams found in the Electrical
Engineering discipline is used, including arrows indicating causal
relationships between signal transitions."

It is a mainstream Linux package and should be easy to obtain. (It is part
of the Debian distribution). SourceForge should certainly have it.
