Re: [neonixie-l] Re: Nixie driver chips

2018-01-23 Thread Terry S

My suggestion would be to contact your friendly TI applications engineer. 
The good ones live to track down this kind of thing, even for hobbyists. 

When I was maybe 13 years old, I contacted TI and they sent me samples of 
the SN74143 to build a project out of Popular Electronics.  And yes, 
they created a lifetime customer. I've done literally millions of dollars 
of business with TI.

Yes, I am sorely tempted by the RasPi. I am considering using MQTT, and I 
will need a server. That might be my excuse to get one...

ESP have way more code space, but come with their own restrictions. 
Still my go-to at the moment though.

I looked at the ATTiny recently for a very small form-factor device, but 
then the ESP is also small and has WiFi, more GPIO and more flash.

2018-01-23 Thread Dan Hollis

Why is it perfectly ok for people to use libc, ncurses, pthread, pcre,
opengl, etc on linux but using an i2c library on arduino is somehow
verboten?

As I stated before, this is the exact same derangement infecting many
in the amateur radio hobby. It turns off a lot of people wanting to get
into radio.

We should be welcoming people to the hobby, especially for the small
subset interested in obsolete display technology.

"pity about the arduino"?

We don't need this elitism and exclusionary attitude.

We should be happy people are taking interest in the hobby at all.

It seems that people have very strong opinions about what MCU (is there a
better term?) they like to use in projects. In particular there are some
strong feelings against the Arduino and the use of libraries. So maybe we
can air our opinions in this thread (in a civil manner! No personal attacks
please, and bear in mind that language can be tricky to interpret at times,
especially if English is not a first language - mods, feel free to close
this down if you think it is open to abuse or not appropriate for this
group).

My own feeling is that libraries are one of the strong suits of a platform
like the arduino - they allow me to focus on what I am trying to achieve,
rather than having to re-invent the wheel (though, obviously, there is
nothing stopping me re-inventing the wheel if I feel the need!). I am a
professional software developer who has written code at all levels - OS
code, libraries, compilers, assemblers, embedded systems, device drivers,
distributed systems, enterprise systems, databases, network protocols,
GUIs, web sites and even applications (though that isn't my strong suit!)
There are probably some areas that I haven't touched. I enjoy it all, but
life is too short to constantly write this stuff, and those who do so full
time generally do a better job of it.

As far as Arduinos go - they are cheap and easy to program and I use them a
lot for prototyping (actually I use the tiny WeMos D1 mini pros now). I
even have one clock that is an Arduino shield, though you wouldn't know it
- its form factor is not that of your average shield. As a testament to its
flexibility, this allowed me to easily extend both the software and the
hardware to better suit what I wanted.

And yes, I have moved on to other hardware, but I still use all those
Arduino libraries.

Surface mounting seems to be another contentious topic. It seems that I
have embraced it whole-heartedly, though I started down that route because
the interesting chips I wanted to use where all surface mount.
Aesthetically I think through-hole components suit Nixie tubes better, and
I like to see the circuitry exposed, though that is also a preference that
I know some others very much disagree with.

Truth is, I want to use it all!

Sorry, my choice of the word hate was intended to be somewhat tongue-in-cheek.  
 I'm relatively tech agnostic in terms of projects, although as a relative 
latecomer, I cut my embedded teeth on the Arduino, so I'm somewhat partial to 
Atmel tech.  In the past though, I've done stuff on the Arduino, and then 
burned it directly onto a compatible Atmel 8-bit chip to place on a board.  I 
haven't actually done of my own PCBs yet though, so I'm still a piker.

 

Hats off for your use of assembly, I haven't done any assembly since my 
Commodore 64 days, but am hoping to get back into it at some point.

Re: [neonixie-l] Re: Nixie driver chips

2018-01-23 Thread gregebert

I wouldn't design a clock without a full datasheet; this looks like a 
totem-pole output driver, and the internal design of a chip that can do 
that at high-voltage is not trivial.

I looked at the offerings from Supertex, and their 64-bit push-pull driver 
IC can only run up to 180V, which is marginal for nixies.

Maybe TI did a custom IC for plasma displays (guessing here, based on the 
SN part number prefix), so a full datasheet may not be publicly available.
The funny thing here is when I do a parametric search for SN75151 on 
ti.com, it pre-hits to SN751518, but does not offer-up a datasheet. So I 
think there's something on their website, but not for public access.

This is the same elitist attitude that continually hurts amateur radio. 
All the old pharts offended by SDR and digital. Not to mention the 
seething rage when the FCC dropped the requirement for morse code.


We should be accomodating to newbies in the hobby, not trying to drum them 
out with better than thou nonsense.

Re: [neonixie-l] Re: mason jar numitrons

Sorry, my choice of the word hate was intended to be somewhat
tongue-in-cheek.   I'm relatively tech agnostic in terms of projects,
although as a relative latecomer, I cut my embedded teeth on the Arduino,
so I'm somewhat partial to Atmel tech.  In the past though, I've done stuff
on the Arduino, and then burned it directly onto a compatible Atmel 8-bit
chip to place on a board.  I haven't actually done of my own PCBs yet
though, so I'm still a piker.

Hats off for your use of assembly, I haven't done any assembly since my
Commodore 64 days, but am hoping to get back into it at some point.

Yes - you can run them at lower currents - you may start to get less uniform 
brightness at some point, but you could PWM them

Typical spec is 55-60v forward voltage,. max current 10-15mA

I've seen the "filament" style LEDs in decorative bulbs and been
intrigued about just such a project.

Glad to see someone followed thru!

[neonixie-l] Thanks: My one-tube-clock

Hi,

I'd like to thank all the folks on here that patiently answered all my 
questions, plus the countless resources on the internet that many people 
have selflessly provided. A year ago, the only thing I knew about 
electronics was how to use a soldering iron. Now I know enough to be 
dangerous (and to actually build my first nixie clock). I settled for a 
one-tube clock, because I found that I used my testbed for that, so I could 
light up the various tubes I have been buying. I can also use it to 
condition cathodes and display digits one at a time so I can test them or 
take photographs. In the spirit of giving back, I documented the project 
at https://hackaday.io/project/28220-one-tube-nixie-clock.

Here are some photographs:







And a video:

Thanks - Paul

RE: [neonixie-l] Re: Nixie driver chips

2018-01-23 Thread Andrew Jardine

Hi Gaston,

 

Thanks for this but this is the same pinout that I have.

The diagram looks as if it’s part of a TV manual, there must be full datasheets 
available somewhere!

These chips are readily available, cheap, run on 5v and are fast!

They really seem like ideal nixie drivers.

If I can’t find any full datasheet then I’ll try some experimentation.

 

Thanks again,

Andrew

Hi Andrew...
   Here is a link to a place where a piece of the datasheet is.

http://radiocom.dn.ua/image/data/pdf/SN755870.pdf

Be patient as it takes some time to load it.
Regards

I can find a pinout and that's it.
These chips seen cheap and readily available new or from old TVs

Nice! Reminds me of these Fixie (read: fake Nixie) displays I saw a
