Micrometer.
Vernier caliper may also work.
Either under $30US.

I don't believe anyone uses vernier calipers anymore. I've got a Helios
dial caliper made a long time ago in Deutschland, but nowadays a caliper
with a LCD is probably a lot cheaper.

I do.

I haven't got a LCD one, but a magazine sends me one every year.
Ok, it's made of plastic, but it works fine, and is accurate enough for
me, seeming to be within about .05mm

I'd like an LCD one of course.

You should shell out the $20 or whatever then (or $100 and get a
Mitutoyo or other brand name with a bit better "feel"). I use mine all
the time- for rough (0.001") width, diameter, inside diameter
(rougher) and depth measurements. A micrometer is useful for precision
measurements, but less necessary for an EE.

Unfortunately, $20 is quite a lot of money at the moment :/

I don't have any real need for it - I've got a 0-25mm micrometer, and
the plastic caliper fills in for the rest.

I don't have any tools that can maintain that sort of tollerance anyway,
so my need is less.

Mm.. 'kay. Hope things get better fast for you.

You don't have a file? ;-) Just double-checking lead pitch etc. is
worth a lot by times.

True.
I don't really have that much that I need to hold accurate tollerances
for anyway.

The file is a much underestimated metalworking tool.

BTW, speaking of tapes.. I read that the company that made Irish and
Ampex tape has closed. Looks like everyone has been going to CD-Rs.

No tears here about that demise. I haven't used Ampex tape since 1969, in
Korea. We switched our three 12-track recorders to 3M tape because Ampex
sandpapered the heads.

This old war horse finally went CD-R and CD-RW about a year ago. CD-RW is
wonderful for PC HD backup. Can't bear to let go of my Teac 4010-SL r/r deck
though. I bought it in Thailand in '71, used it until '81 or so, and then
packed it in its original box. It's been used twice since then. Every once in
a while I pull it out to show to some kid as an antique.

What wire gauge, if one at all, do metricated industrial countries
use?

France, Germany, Russia, China, for example.

There is an IEC standard, IEC 60317-0-1, which specifies a range of

metric diameters for enamelled copper winding wires.

Wire diameter in mm.
0.05 0.1 0.15 0.5 0.75 1.00 2.00 mm, for example.

If they carry american wire sizes they are
also declared in wire diameter in mm.

Ohhh... I assumed anyone serious would be using a Mitotuyo ? digital
LCD
vernier caliper anyway. We certainly have one.

I'm trying to figure out why they would be called vernier when they have a
LCD display.

To distingush it from a micrometer caliper at one end of the tool
spectrum, and a monkey wrench at the other. ;-)

Cheers!

You can get low-end LCD calipers in the US for the equivalent of about
GPB8 plus tax. For GPB1 (<$1.99) I think you'd get some stamped or
plastic item that would only be good to 0.01".

No, they are metal, and claim to measure to 0.001 inch, 0.02 mm. I've
checked mine against a good micrometer and it's as accurate as I can
read the vernier. YCCMV, of course.

Who still makes audio recording tape? I thought Ampex was the last.

Whoa! Right now I have four shoeboxes of old Morse-code tapes sitting
on the workbench waiting to be carried out to the trashcan. Should I
advertise them on Ebay instead?

Depends. Some tapes (reportedly mostly from the 1970s) disintegrate. A
couple of years ago I had no trouble playing my tapes from the late 1960s,
but...

I'd attempt to hawk em on ebay before tossing them. Maybe somebody can

do something with them regardless of condition or relevance of code
practice. It doesn't make sense to just cart them to the dump without
trying.
