Seven Bit Colored Analogue Bar Graph Generator DEMO... (Python)

2011-03-17T22:14:52-07:00

Python recipe 577612 by Barry Walker (analogue, anim, audio, bargraph, color, colour, demo, display, linux). Revision 3.

..For STANDARD Python 2.6 and above...

This code will display a horizontal full colour analogue "VU" style meter. It displays green for normal, yellow for warning and red for danger with a critical error beep near the end of full scale, at value 120+.

This version is for Python 2.6 and above and only for the Linux, (*nix?), platform.

It is an "at a glance" display that is in colour rather than having to read say a digitally generated number.

A Python 3.x version can be found here:-

http://www.linuxformat.com/forums/viewtopic.php?t=13443

This has uses "for at a glance" voltmeters, ammeters, data-loggers, anemometers etc, etc...

Watch for wordwrapping etc...

Colo(u)rs Inside Text Mode Python... (Python)

2012-08-21T21:01:57-07:00

Python recipe 578101 by Barry Walker (amiga, apple, color, colour, demo, display, e_uae, linux, macbook_pro, windows, winuae). Revision 2.

A simple DEMO to show how to enhance Python inside a Terminal. This works on Classic AMIGAs, E-UAE, Debian Linux 6.0.0, PCLinuxOS 2009, Windows XP and Vista and WinUAE, from Python 1.4.0 to 3.3A2.

Due to a complaint about my _fun_ upload recently I decided to post this so that the MANY can now find out how to manipulate text inside a Python Terminal window so that it looks much better.

Pseudo-3D effect in text mode... (Bash)

2013-09-10T21:23:58-07:00

Bash recipe 578655 by Barry Walker (3d, apple, bash, color, colour, display, linux, macbook_pro, text).

This is just a simple DEMO to display a pseudo-3D effect using a bash script. It generates a recessed box and a button and writes some thext inside bot.

There are two pieces of code, one for Linux, and one for OSX 10.7.5...

The Linux version also works on OSX 10.7.5 but is harder to see so a near identical version using the default OSX terminal colours was craeted instead.

You will have to split the two code pieces up yourself to run...

A Simple Clock, Well Maybe Not That Simple... (Bash)

2013-07-17T17:40:18-07:00

Bash recipe 578610 by Barry Walker (apple, clock, digital, digits, display, large, macbook_pro, readout, terminal).

Hi all...

Do you remember this little snippet?

http://code.activestate.com/recipes/578079-pure-fun-for-text-mode-python/?in=user-4177147

Well it was voted down, but who cares? I surely don't! So to those that voted this FUN piece of Python coding down, you are now about to see what the aim was.

However although I have subsequently done what I said I would, that is, to create large digits as an _at_a_glance_ digital readout for a project in Python I have decided not to upload it. However I have decided to let this one go as a bash/shell script instead.

It is a nothing but a simple clock, well, maybe not that simple; but as I am into shell stuff at the moment I thought I would share this with you.

The terminal does have its colours changed and the cursor disabled for the session but I expect you big guns to be able to return back to normal in a jiffy.

I am an amateur coder and if that is easy for me then you pros should have no problems.

This code is not like most of my other stuff as is NOT Public Domain...

It is only a DEMO to see what an at a glance display would look like in a terminal.

Move away to a distance and see which of the two time readings you can still read... ;o)

It is for a Macbook Pro 13" OSX 10.7.5 and uses bash imode. It will probably work on most Linux machines too but I haven't tested it...

This is purely a DEMO only and any other special effects, (e.g. flashing colon every second), alram, etc, I have already experimented with and is easy enough to do...

My intention is to use this as a kids level text mode digital voltmeter I am doing.

Enjoy...

A DEMO 6 Bit At A Glance Colouerd Bargraph Generator. (Bash)

2013-01-16T12:26:55-08:00

Bash recipe 578391 by Barry Walker (analogue, anim, apple, bargraph, bash, beep, color, colour, demo, display, generator, linux, macbook_pro). Revision 2.

This code generates a horizontal coloured real time bargraph generator anim for a Macbook Pro 13 inch, OSX 10.7.5, using the default standard Terminal only.

It is UNTESTED on Linux variants but I would like any successful Linux tryers to make a comment in the comments section and tags will be added accordingly otherwise I will assume it does NOT work on other UNIX like variants.

It is a derivative of my 7 bit bargraph generator for Python on this site elsewhere.

The Terminal colours WILL be changed on running but it is simple to return it back to its original state.

Read the code for more information.

Enjoy, (and a Happy New Year)...

http://code.activestate.com/recipes/577771-simple-lf-audio-oscilloscope-using-standard-text-m/?in=user-4177147

Well here is an August 2012 vintage MacBook Pro 13 inch version of it for OSX 10.7.5...

This is proof of concept code for a kids level project I am doing for a MacBook Pro, 13 inch, OSX 10.7.5. A DEMO to show how to display a waveform using standard text mode Python. "pyaudio" must be installed for this to work. Levels are set using the standard audio mixers, (System Preferences -> Sound).

Just whistle a signal of say 300Hz to 3KHz, (normal voice spectrum), using say, the internal mic, and watch a waveform appear inside the X-Y graticule.

Read the code for more information.

This code is GPL2, but, the hardware information is Public Domain.

(I am looking into including Windows and Linux variants too using pyaudio to access the sound system.)

Kids Level Analogue Data Logger, (Transient Recorder), Program. (Python)

2011-07-31T16:14:48-07:00

Python recipe 577796 by Barry Walker (amiga, analogue, anim, apple, arduino, data, demo, display, e_uae, linux, logger, macbook_pro, program, windows, winuae). Revision 2.

This code is kids level Analogue Data-Logger(/Transient-Recorder), using the Arduino series of dev' boards.

It is no where near completion and is a second feeder/feeler upload only.

It is designed to work from Classic Text Mode Python from Versions 1.4.0 to 2.7.2 on a Classic AMIGA, WinUAE, Linux and Windows, (32 bit), to Vista. Not tested on Python for Windows 7, (32 bit), nor Mac OSX flavours as I don't have these OSes.

Linux versions run from a default root terminal for the time being.

The Arduino dev' board IS catered for in the code for the above platforms just thoroughly read the code for more information. It defaults to a DEMO mode so you can see it working...

The test code for the Arduino Diecimila Dev Board is here:-

SimpleTron3x.py.

This code is a FUN program only to DEMO how to draw in a text mode Python shell.

There is an inkey() "function" extracted from a "class" recipe on this site. See code for more information.

This was tested on PCLinuxOS 2009 with Python 3.0.x and Debian 6.0.0 with Python 3.1.x.

This ASSUMES an 80 x 24 Python shell window.

Issued as Public Domain, you may do as you like with this code.

An EM87/6HU6 Magic Eye Valve/Tube Animation DEMO... (Python)

2011-05-15T10:21:10-07:00

Python recipe 577695 by Barry Walker (analogue, anim, apple, demo, display, linux, macbook_pro, windows).

This DEMO displays the action of an EM87 Magic Eye tuning indicator using a standard Python 2.6.x or greater install. It is for at least Windows Vista 32 Bit and at least Debian Linux 6.0.0.

It is for FUN only and shows how to generate yet another analogue display using a default text mode install.

With careful thought and viewing between Code Page 850, (Windows Vista onwards), and Code Page 437, (EFFECTIVELY Linux), one can pick the "graphics" characters to generate some interesting old style text mode displays on screen.

Simple LF Audio Oscilloscope Using Standard Python. (Python)

2011-04-07T17:17:57-07:00

Python recipe 577644 by Barry Walker (anim, audio, demo, display, linux, oscilloscope, scope, sound).

AudioScope.py

I think this might be a first for both Python.

Initially uploaded to LXF, now also here under the MIT licence.

I am building a kids level seismometer and wanted to use standard Python inside Linux.

This DEMO code was my starter idea and looks as though using standard ASCII only might just work a real treat.

I've issued it to LXF under the MIT licence for future reasons.

It doesn't look much on screen except that the waveform(s) shown is/are a basic visual, electrical representation of your voice. ;o)

It is possible to link the earphone socket on this notebook to the mic input and start the Audio Function Generator, elsewhere in this site, in a separate Python terminal and see those waveforms inside the AudioScope.py`s own Python terminal.

This grabs a 1 second 8KB burst, and then displays it onto the Python terminal. The timebase, amplitude, trigger, single shot and others are not included but the main grab and display using /dev/dsp is shown. This can be made platform independent by changing the /dev/dsp to something external like the Arduino Dev Board. This uses STANDARD Python 2.5.x and later and tested on PCLinuxOS 2009 and Debian 6.0.0.

Simple analogue anim and digital voltmeter with alarm DEMO... (Python)

2011-03-04T19:47:37-08:00

Python recipe 577596 by Barry Walker (amiga, analogue, anim, audio, demo, digital, display, e_uae, linux, voltmeter, windows, winuae).

I needed a simple standard Python analogue and digital display along with an overload beep when used as a basic voltmeter.

Analogue readout, for quick glance. Digital readout, for better accuracy. Beep, to warn me of impending doom... ;o)

This was my starter code and works from Python 1.4.x to 2.7.x on MINIMUM platforms, AMIGA A1200, MS Windows ME and Knoppix 5.1.1. It is a stand alone program and the easiest way to start it is to import it as though it is a module.

(I DO have a Python 3.x.x version too and WILL be uploaded here in the future.)

Although this is a DEMO it did access, (home built), HW from various ports on differing platforms.

This module IS needed for it to work:-

http://code.activestate.com/recipes/577588-clear-screen-and-beep-for-various-platforms/?in=lang-python

These simple HW access modes using standard Python code WILL be released in the future.

Clear screen and beep for various platforms. (Python)

2011-02-26T14:26:02-08:00

Python recipe 577588 by Barry Walker (amiga, audio, beep, clearscreen, display, error_beep, error_sound, e_uae, linux, screenclear, sound, windows, winuae).

This little module gives a clear screen and beep for the classic AMIGA, WinUAE, Windows and Linux all in CLI/Command-Prompt/Terminal mode.

It works from Python 1.4.x to 2.7.x; talk about backwards compatibility... ;oD With very little modification it will work on Python 3.x.x easily.)

See the file clsbeep.py attached for more information.

it is saved as clsbeep.py and placed into the Python - Lib drawer or where-ever the modules are located and called as a module:-

>>> import clsbeep

Its usage is:-

clsbeep.cls() and clears the screen. clsbeep.beep() and creates an error beep. clsbeep.both() creates an error beep first then clears the screen.

It is Public Domain and if you modify it to suit other platforms please let me have a copy of your code... :)
