PostPosted: Sun 16 Mar 2014, 05:08    Post subject: Gracias Walter  

Gracias Walter, la verdad es que el nivel de los programas para electronica en Linux esta subiendo bastante.

Yo utilizo Windows unicamente por dos cosas, una es por Orcad y la otra Proteus.

Gracias al nivel que esta cogiendo programas como Kicad y Geda .. Orcad va pasar ya a la historia.

Con respecto Proteus es un poco mas dificil pero en el caso de microcontroladores ya casi no hace falta, y es muy probable que breve tambien pase a la historia.


Echaba mucho de menos poder correr estos programas con Puppy y bueno gracias a gente que se esta tomando el trabajo esto ya es posible.

Asi que espero que se vaya mejorando cada vez mas, y por eso esta abierto este tema aqui ....

Nos vemos... saludos.

PostPosted: Sun 16 Mar 2014, 05:54    Post subject: Con respecto Xoscope  

Con respecto a todos aquellos que quieran montar un osciloscopio con el Xoscope, Rodney Byne en el foro de Ingles nos hace una abvertencia bastante oportuna que tenemos que tener en cuenta.

Rodney Byne nos dice que no debemos superar los 150mv RMS en la entrada de microfono.

Por eso los diodos puestos en oposicion y en paralelo, para proteger el circuito de tensiones superiores a esas.

Rodney Byne nos señala de la tension proveniente de la salida de microfono de +3 V para microfonos electret el condensador de 470 nF nos desacopla esta tension y evita que se nos meta al circuito.

En definitiva un buen circuito para proteger nuestra entrada de microfono y que se puede modificar para adaptarlo a nuestras necesidades pero teniendo en cuenta siempre estas consideraciones.

Saludos.

PostPosted: Mon 17 Mar 2014, 09:23    Post subject: pc audio test lab  

Hola to everyone,

Your friend mister_electronico invited me to introduce myself
on your Spanish Engineering forum page.
We have been communicating for a while about matters
to do with audio and since he is now very busy on
work-related projects, he thought my schema would
also interest you.

In answer to one of his last questions, no I do not ask
any copyright. All my suggestions are gratis to everyone.

My schema, my hobby plan, is to collect together
audio items so far discussed as a pc audio test lab
on anyone's laptop or netbook.

His xoscope pet, his siggen pet, my contribution of Baudline Analyzer,
my contribution of pc mic protection circuit (as above)
and my contribution of a simple pc scope probe for examining waveforms to 5v pk-pk (as below)

I also requested he look at the possibility of writing a pet file
for an audio millivoltmeter design to read 10 to 100mv to 20khz
bandwidth.

This is complicated for him to compile and de-bug, so it may
or may not be possible to achieve.
I hope it is.

Thanks for reading this post and Adios.

PostPosted: Tue 18 Mar 2014, 05:47    Post subject: Hi Rodney  

****Translations at the end *****

Muchas Gracias Rodney por tu esquema. lo de los derechos de autor era solo un chiste yo ya lo suponia.

Este esquema supone un mejor aislamiento entre el circuito de entrada y de salida.

Como te dije lo de hacer un milivoltimetro es un poco mas complejo, por que yo lo hago atraves de un microcontrolador, no se tus posibilidades para poder montar y programar microcontroladores.

Te dije la posibilidad de hacerlo atraves de la tarjeta de sonido, y como te dije la tarjeta no mide tensiones CC, asi que tendria que ser un convertidor de CC a frecuencia , la tarjeta de sonido detectara la frecuencia y la convirtiese a valores de tension.

Pero esto esta fuera de mis conocimientos de programacion, Yo no se como se podrian capturar esos datos en la tarjeta de sonido.

Otro metodo que si se podria hacer seria atraves del puerto paralelo del ordenador, aunque hoy en dia el puerto paralelo esta desaparecido en los nuevos ordenadores.

Pero en los antiguos se podria hacer :

convertidor analogico digital ---- Datos 8 bits --- puerto paralello - PC - Programa C --- programa Gtkdialog.

Pero como te digo los puertos paralelos estan desparecidos en los nuevos ordenadores.

Mi ordenador no tiene ya puerto serie y el puerto serie con el que yo trabajo es un cable USB - RS232.

No he visto convertidores USB - (PUERTO PARALELO) pero puede que los haya.

Rodney cuentame cuales son tus capacidades y posibilidades de como hacerlo.

Nos vemos ... Saludos.

Thank you Rodney for your scheme. about copyright was just a joke I already supposed .

This scheme means better isolation between the input circuit and output .

As I told you to make a millivolt is a bit more complex, I do it entirely by a microcontroller , I don't know your possibilities to build and program microcontrollers.

I told you doing so entirely by the sound card, and as I said the card does not measure DC voltages , so would have to be a DC frequency, sound card detected frequency and voltage values ​​turned to the .

But this is out of my knowledge of programming , I do not know how you could capture that data into the sound card .

Another method that could be done would be if entirely by the computer's parallel port , although today the parallel port is missing in new computers .

But the ancients could do :

digital analog converter ---- Data 8 bits --- Paralello port -- PC -- Progam C --- gtkdialog Program .

But as I say parallel ports are disappeared in new computers .

My computer does not have serial port and I work with a USB cable - RS232 .

I have not seen USB converters - ( PARALLEL port ) but may exist.

Rodney tell me what your capabilities and possibilities of how to do.

See you ... Regards .

Hola Rodney si existe el puerto paralelo

http://www.ebay.com/bhp/parallel-port-to-usb

Lo que tendria que mirar como se deja programar y sobre todo si es bidirecional.

Este podria ser un buen metodo para mucha gente para capturar datos al ordenador de forma simple.

Voy a ver si me hago con uno y te cuento.

Nos vemos

Hi Rodney paralell port USB-parallel port exists

http://www.ebay.com/bhp/parallel-port-to-usb

What would have to look as allowed program and especially if it is bidirectional

This could be a good method for many people to capture data to your computer simply.

I'll see if I get one and tell you.

PostPosted: Tue 18 Mar 2014, 19:13    Post subject: Change of plan to plan B  

Hola,

After reading about your software design difficulties for a
sound card millivoltmeter I have a different idea - so plan B.

No I have two modern laptops without serial or parallel
ports, so please put out of your mind all you mentioned
so far, but thanks for trying.

My new idea is to use the Baudline db scale on left hand side,
only as an indicator with correlation to absolute millivolts.
I have proved here that the db scale is linear so no problem.

The maximum audio level recommended for pc mic safety is
150mv RMS before squaring occurs, therefore I use here
100mv RMS as the highest working test point, which is -18db.
As mentioned previously, -20db equates to 77.5mv RMS which is
the most useful test point for pc audio level comparison purposes.

As you probably know, every 6db reduction is half voltage,
so for example -26db is half 77.5 or 38.75
and -32db is half 38.75 or 19.37 etc etc etc.
It's easy now to correlate the vertical scale to mv and a
two-column scale on paper can thus be made up by the user.
So no essential need in this case for a s/w millivoltmeter.

The next step is proving the correct signal level entering
the pc mic socket, with the mic slider gain setting at about
1/3rd up from bottom and pc mic software boost OFF.

Preparation for setting up and test cables required:
The user must make an audio patch cable from an external
generator to the mic socket.
Or a loop-back cable from pc speaker output socket to mic
input socket with say your internal siggen enabled at 1khz
and "gain" at about 0.39 for 77.5mv RMS sine output.

There should be an extra separate cable, with one end
parallel soldered to the mic jack plug connections and the
other end suitably terminated to plug into a good quality
general purpose multimeter capable of reading low level
AC volts.

I now draw your attention to my web article contribution
in CXI, for a detailed guidance explanation on this subject:
http://www.zen22142.zen.co.uk/Circuits/Testgear/audiotestset.htm

It would be helpful to read the whole article on this small test set,
but please pay extra attention to the section Calibration using
the good multimeter.
As explained, the multimeter reading in average display,
is mv RMS x 0.9
So 77.5mv is .069v.

Finally when the correct reference mic input signal is proved
at .069v on the multimeter, Baudline input gain slider can be
set so the fundamental tone spike tip is at -20db and the rest
of the db scale is thus correctly referenced linearly.
-----------------------------------------------------
If a fluctuating audio signal is then applied to the pc, by looking at
Baudline, the whole dynamic range of audio can be assessed
both in db and absolute mv terms.

I hope all this information for my plan B is understood.

Best regards to all.

Hi Rodney Byne

I have read to post and will analyze carefully, today I had a hard day at work, I've been busy.

But it may have found the solution.

Watch this python program that in theory you read the frequency of the microphone input.

I have not tried, but if it really works could be the solution to millivoltmeter.


To run you have to have the devx-xxx.sfs Puppy distribution corresponding to your file installed or python.

Works by terminal and run:

python Frecuenty.py

See you .... greetings.

********************************

Traduccion:

He leido to post y lo analizare detenidamente, hoy he tenido un dia duro de trabajo , he estado muy ocupado.

Pero puede que haya encontrado la solucion.

Mira este programa de python que en teoria te lee la frecuencia de la entrada de microfono.

No lo he probado, pero si es verdad que funciona podria ser la solucion al milivoltimetro.


Para ejecutarlo tienes que tener instalado python o bien el archivo devx-xxx.sfs correspondiente a tu distribucion Puppy.

Funciona por terminal y para ejecutarlo:

python Frecuenty.py

nos vemos.... saludos.

PostPosted: Wed 19 Mar 2014, 19:33    Post subject: Not understand, which Puppy do I use?  

Re your new idea,
I don't understand this, please explain:

"To run you have to have the devx-xxx.sfs Puppy distribution corresponding to your file installed or python.

Works by terminal and run:

python Frecuenty.py"

After downloading this small file, terminal says
Python: command not found.

To enable this app to work, which Puppy distro
should I be using that contains python?
Is it Precise or Slacko or Quirky or Quirky Tahr?
Those are each on flash sticks.
I am currently in Quirky, so obviously python is not installed.
This stuff is too complex for me, I'm a retired analogue technical
engineer of 68, not a code programmer.

Bye.

Hi Rodney

Forgive me explain better, look I'm currently working with Slacko-5.6 PAE.

As for compiling C programs, C + +, python, glade and more.

I have to get off a corresponding sfs file to my distribution of Puppy in my case this is:

devx_slacko_5.6.0.sfs

So for example if you're working with Precise or Quirky you much downloading this sfs file from the same place where you got puppy version


If you're working with sets and your pupsave eg appointing puppyprecise_save_5.7.sfs

You must download the sfs devx_precise5.7.sfs or something like.


Once you go downloaded, go to Menu > Setup > Load-sfs on fly.

And loads this file. The sfs file place it in /mnt/home

And you will be working.

Then test.

python Frecuenty.py

The program is very simple, only by terminal and the only thing you see is the frequency value that enters the microphone

see you.

My Idea

A quick post because I am working.

My idea is this:


Converter voltage - frequency <==> Frecuenty Program <==> C Program <==> gtkdialog. for presentation

I have not tried the program Frecuenty in the lab, I have not had time, but not very accurate but I do not care, you would make the necessary corrections or hatfware software.

See you.


Traduccion

Un post rapido por que estoy trabajando.

Mi idea es la siguiente:


Convertidor tension - frecuencia <==> Programa Frecuenty <== > Programa C <==> Gtkdialog. para presentacion

No he probado el programa Frecuenty en el laboratorio, por que no he tenido tiempo, pero aunque no sea muy preciso no me importa, le haria las correciones por software o hatfware oportunas.

Nos vemos.

PostPosted: Thu 20 Mar 2014, 10:51    Post subject: Need more help with sfs  

Hola,

Now using the new version Slacko 5.7 for this test.
Help please I am having difficulty here:

Slacko5.7 PPM says this with a green tick in front strings_sfdisc-2.2.1 utils for slacko already installed:

If I try to load the above command on the fly in the white box,
it returns fatal: /root/strings_sfdisc-2.2.1 not found.

PPM doesn't understand the request to get:
devx_slacko_5.7.sfs
Red box says Not Found

What am I doing wrong?

Cheers
