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)

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...

For MacBook_Pro-Heads Only. Simple LF Audio Oscilloscope Using Standard Text Mode Python. (Python)

For MacBook_Pro-Heads Only. Simple LF Audio Oscilloscope Using Standard Text Mode Python.

SimpleScope_OSX.py

Do you remember this upload from myself on 26-06-2011...

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.)

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.

Pure Fun For Text Mode Python... (Python)

Python recipe 578079 by Barry Walker (apple, demo, display, linux, macbook_pro). Revision 2.

Printing to the screen with a difference. ;oD

Works on almost any version of Python running in a terminal inside Linux.

Simple LF Audio Oscilloscope Using Standard Text Mode Python. (Python)

2011-06-26T21:42:55-07:00

Python recipe 577771 by Barry Walker (anim, audio, demo, display, linux, oscilloscope, scope, sound).

A Linux DEMO to show how to display a waveform using standard text mode Python. The audio device /dev/dsp is used and must be available. Levels are set using the standard audio mixers.

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

This method WILL be used for a program proper and may be uploaded to this site in the future.

SimpleTron3x.py "Game" To DEMO XY Drawing Using The Keyboard In Standard Text Mode Python. (Python)

2011-05-29T14:28:19-07:00

Python recipe 577728 by Barry Walker (anim, demo, display, game, linux).

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.

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.

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... :)
