I would think that USA is big/well known enough and probably the  largest 
user of Nixie for fun devices that a programmer would have implemented  
(easily) a Fahrenheit feature.
 
A feature which would take maybe a couple hours (at most) to add, would be  
smart to open your product open for a wanted item for an entire country.

In the article, the author states that F is not on the IN-19 tube he used 
and that is why there is no Fahrenheit feature.
Personally, I would displayed Fahrenheit after the C reading and simply 
blanked the IN-19.

No-one that I know of in the UK still uses degrees F, except superannuated 
old fogies who still believe we have an empire...

The only thing you need to know is that the BBC and the Queen use degrees 
C... I rest my case... 

...though we use imperial measures for length (but often also metric) and 
distance, speed & area, volume of draught beer and milk (but not petrol) 
etc. simple really.

This is the joy of DIY - use the Elektor project as your inspiration and do 
your own thing based on it.

Far easier - the reason most of us design/build own own stuff is that 
everything else is a compromise - someone else's view of what we want.

30 years ago I used to build my own speakers - now I'm just getting back 
into that as I'm unhappy with paying someone else a lot of money to give me 
not quite what I asked for!

People talk of 1/4 of a %! (That to me is the 'best' one, combining

I see engine capacity measured in kilowatts, but torque in pound-feet.

My favourite mixed one is tyres - for example, P225/60R17.  That's a 225 
millimeter wide tyre for a 17 inch wheel,
with a 60% aspect ratio.  That's just nuts.

Agreed!  As I got into electronics at an early age, I was already familiar with 
the prefixes (pico, micro, milli, kilo, mega, and so forth).  For some
reason, "nano" seemed to get left out for a while (as "pico" did, back in the 
days when a 200pf capacitor would be referred to as a "200mmf condenser").

> Anyway if you want Fahrenheit just remember Tf = (9/5)*Tc+32, simples ;)

I figure people who prefer Fahrenheit probably aren't terribly particular about 
accuracy, so I approximate Tf = 2⋅Tc.

Then again, I like to give my age in hexadecimal.

A feature which would take maybe a couple hours (at most) to add,

And smaller capacitors, less lamp flicker, easy inductive chargers, and all 
sorts of good things.  There's been some research on electrical effects on 
living tissue, and it
turns out that the 50-60Hz range is actually one of the more damaging ones, as 
luck would have it.  400Hz would be a big
improvement in that respect as well.

I've heard objections that 400Hz has a shorter wavelength, and would make long 
distance power transmission more difficult,
but it turns out that doesn't necessarily apply, as much long distance power 
transmission is done via DC these days, now that
high-powered silicon is available to convert between AC and DC.

And half-wave rectified 400Hz makes a dandy nixie power supply - flicker is 
much less of a problem.  (to drag this thread
somewhere back on topic)

Mystery of the small K is solved: The tubes is developed to use in Cyrillic.
In Cyrillic the lower case k has the same shape as the upper case K but is
smaller [ http://www.hts-homepage.de/Suchen.html }.

But what does it matter if you use it as a K in your thermometer ?

Further: The IN-19B has an F, but unfortunately not in combination with ° It
is also missing the %. Up to you to use both the tubes if you insist to show
your temperature in F

That is funny, I once read an old scientific paper where they talked 
about capacities measured in centimeters and I was very confused because 
I am used to SI. Then I remembered the formula to calculate the capacity 
(you know, C = e0*e*A/d) and thought: Hey, they might be using a system 
where the e0 is set to unity, and so it was... ;-)


Jens


I have an old 'condenser' marked in cm [centimetre/centimeter].
One recent doc explaining this early use of centimeter ...
http://web.mit.edu/sahughes/www/8.022/lec06.pdf
"In cgs units, we measure charge in esu and potential in esu/cm. The 
unit of capacitance is thus just the centimeter!"

Agreed!  As I got into electronics at an early age, I was already 
familiar with the prefixes (pico, micro, milli, kilo, mega, and so 
forth).  For some
reason, "nano" seemed to get left out for a while (as "pico" did, back 
in the days when a 200pf capacitor would be referred to as a "200mmf 
condenser").

of Electrical and Electronics Engineers (IEEE)  "There is speculation that 
the value of 50 Hz was chosen in Europe as being an element in the metric 
“Series of Preferred Numbers,” proposed by the French army engineer Charles 
Renard in the 1870s. Indeed, the R10 series, consisting of the following 
rounded values 10, 12.5, 16, 20, 25, 31.5, 40, 50, 63, 80, 100...See so we 
went with metric way back! Now to go and grab my 'yard stick'

This is the one with the SHT21 sensor on the little daughter board?  The NC 
pins are pins 3 and 4, and
the unconnected pads are the ones toward the through-hole pins.  To put it 
another way, the notch (cut
corner) on the die pad on the bottom should point away from the through hole 
pins, and the sensor
opening on the top of the chip should point toward the through hole pins.

I don't have this kit, so I can't take a photo, but if it would help, I can 
make up a diagram showing the placement
of the chip.

There are several makes of the SHT21 one is fitted on a small SMD print, but
an other on has an elongated print with header pins. Further there is a
Arduni compatable and an I²C compatable type.
I am busy to re-develop the original design to extend it with a real time
clock as a reference for shut off the nixies at night a nightly scan of the
nixies to avoid cthode poisoning, a PIR sensor to activate the hv when a
person enters the room or unit at darkness. Fianlly I use the more charming
IN17 instead of the IN14's that have became scarse and expensive. The high
voltage will be derived from the more efficiënt and smaller Taylor supply.
The sensor comes outside the case to get a more reliable read-out (no
warming up by the components inside) or in a 'tunnel' with mechanic
ventilation.

I have attached a phot taken with my USB microscope with the sensor placed,

I shall remove the cap before reflow.

I did to.  I'm in the UK and the only supplier I could find was Farnell at 
a whopping £18.83 but now they are for sale at £2.91.
Depressing as the first I bought I destroyed : (

I think an email to Farnell is in order to find out why the price

Update:  Now working perfectly.  Thank you again for the advice.
I must admit to being hyper nervous about the reflow on an electric skillet 
but it worked.  Not bad for a first effort and a £15 skillet, even if I say 
so myself.
I also got a very generous refund on the two sensors I bought before the 
price decrease from Farnell : )  How good is that!
Excellent customer service.

OT Mixed measure Re: [neonixie-l] Nixie thermometer in Elektor journal

2012-07-04 Thread Charles MacDonald



Distance/length: miles/yards/feet for distance but metres/centimetres for 
building materials (and drawings)


gee, It is just the reverse in Canada, with Km for Distance, but things 
like Plywood still come in 4X8 foot sheets to fit on studs spaced at 18 
inches.


Small things may come in either, but they make the Kids come to school 
with rulers that are ONLY in cm to ensure that they learn that system first.



My favourite mixed one is tyres - for example, P225/60R17.  That's a 225 
millimeter wide tyre for a 17 inch wheel,
with a 60% aspect ratio.  That's just nuts.


That is a work in progress, in the 1960's  Tires were sized line 7.50X14 
(7 and a half inches on a 14 inch wheel.)

Re: OT Mixed measure Re: [neonixie-l] Nixie thermometer in Elektor journal

2012-07-04 Thread Tobias
My preferred approximation from F to C would be dividing by two but
still taking the 32 into consideration...

What I can't quite understand about the Imperial system is why they
decided to go with 3, 12 and 16.
I.E. 12 inches for a foot, 3 feet makes a yard. And 16 oz a pint. On
top of that all the fractions are 2-related. 1/2, 1/4, 1/8, 1/16. Why
not just 10, 100, 1000!?

My biggest embarrassment is to go to a hardware store, stop in front
of the wrenches cabinet and start making mental math just to find out
what is the next bigger size after finding out the one I have in my
hands is a little bit too small! hahahaha

Forget going from square inches to square feet in less than 2 seconds!

Anyway, in Brazil we sell tires just like in USA. Bronze and Stainless
Steel are sized in inches. Mild and special application Steel are in
Metric. Same for Plastics.
All the first big companies came from Germany or Italy (metric) or
England and US (imperial). The country had no regulations at the time
and we got stuck with both! =)
