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...

Well the Python version of the top URL has been uploaded to AMINET on 01-08-2013...

Now the big gun that complained about my fun Python upload and voted it down can see that this was a serious attempt ae viewing "Hello World!" in extra large xharacters.

This is the result in Python...

It is ONLY uploaded to AMINET and that is where it will stay.

If you want it then use the pointer inside code section.

Remember to change the BIG_TIME.py.txt file on AMINET to BIG_TIME.py...

Designed around a Macbook Pro OSX 10.7.5 for the Classic AMIGA platforms and works on Debian 6.0.x and PCLiuxOS 2009 using Python versions 1.4.0 to 3.3.2 inclusive...

Although the description in the AMINET readme below is for an AMIGA environment it does not take a genius to adapt it to the other platforms...

Boy was this difficult to get working in a single Python script...

ENJOY...

This is the AMINET readme file:-

Short: A Big Digital Clock Python Script. Author: wisecracker@tesco.net (Barry Walker) Uploader: wisecracker@tesco.net (Barry Walker) Type: dev/src Version: 1.00.00 Architecture: generic; m68k-amigaos

Distribution: Public Domain, Emailware.

============================================================================

Architectures: Classic AMIGAs, E-UAE and WinUAE.

MINIMUM Requirements Are:-

    68EC020 CPU and 2MB RAM total, example, a standard A1200(HD).
    WinUAE Version 1.5.3 minimum. 
    Standard OS3.0x install or better.
    Python Version 1.4.0 or higher.
    (Also, OSX 10.7.5, Debian Linux 6.0.x and PCLinuxOS 2009.)

History.

01-08-2013. Version 1.00.00:- Original upload to AMINET...

This is dedicated entirely to the AMIGA community and AMINET and will not be uploaded elsewhere.

To install just download the "BIG_TIME.py.txt" file and rename it to "BIG_TIME.py" without the quotes. Drag this file into your AMIGA PYTHON: volume and...

From a minimum of Python Version 1.4.0 prompt:-

>>> exec(open("PYTHON:BIG_TIME.py").read())<CR>

And away you go...

This code is/was designed to work in all versions of Python from 1.4.0 to 3.3.2 on at least the platforms shown in the Architectures: section.

It was developed entirely on a Macbook Pro OSX 10.7.5 and finalised using MEmacs for the AMIGA.

This is just a simple DEMO to show how to generate large digits in Python and put them to use as an _AT_A_GLANCE_ digital clock.

It starts up by generating all of the characters available for the DEMO for five seconds then goes into the clock proper.

As this code is multi platform AND multi Python version then it is issued as GPL2...

>>> exec(open('/home/G0LCU/Desktop/Code/d2b.py').read())
>>> a=78
>>> type(a)
<class 'int'>
>>> b=d2b(a)
>>> print(b)
b'N'
>>> type(b)
<class 'bytes'>
>>> text="\x00(C)2012, B.Walker, G0LCU.\xFF"
>>> len(text)
27
>>> type(text)
<class 'str'>
>>> newtext=t2b(text)
>>> len(newtext)
27
>>> print(newtext)
b'\x00(C)2012, B.Walker, G0LCU.\xff'
>>> type(newtext)
<class 'bytes'>

It requires NOTHING special at all to work and can be run like above or imported from the correct "Lib" drawer/folder/directorfy as:-

>>> import d2b

And when imported called as:-

>>> d2b.d2b(some_number, optional_some_other_mumber)<RETURN/ENTER>

>>> d2b.t2b(some_ASCII_string)<RETURN/ENTER>

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.)

Create replica of the existing directory structure with only specified extension files. (Python)

2012-11-16T08:30:31-08:00

Python recipe 578303 by Achal Rastogi (bioinformatics, biology, directory, fileextensions, replica). Revision 2.

The program creates a replica of existing directory structure with specified extension files only. The program maintains the directory-sub-directory architecture while executing. User has to provide two arguments, First the path of existing directory,whose replica has to be created and Second, the path of directory, where the replica has to be created. This program is developed to fetch files with ".pl" (perl) extension, while maintaining the directory-sub-directory architecture. User can modify it, with his/her interested file extension, like ".txt", ".doc", etc.

A Crude Baby Alarm For Standard Text Mode Python And Linux. (Python)

2012-08-02T18:05:29-07:00

Python recipe 578232 by Barry Walker (alarm, audio, baby_alarm, linux, sound).

This is a simple audio monitor that records about 1/2 second of sound then immediately plays it back in a continuous loop.

If you are testing with a laptop's, (etc), internal microphone be aware that acoustic feedback might occur...

This could be a use for your now aging netbook... ;o)

Amplitude Modulation - Tremolo, Was:- An Audio/Sound Snippet For Linux... ;o) (Python)

2012-01-21T14:18:28-08:00

Python recipe 578013 by Barry Walker (amplitude, audio, demo, linux, mod, modulation, sound, tremolo). Revision 2.

This IS for the big guns as well as the amatuer...

I am always being told that too many comments inside any code is bad and that professional coders are clever enough to work out what a program does without comments...

So here goes! This snippet of code hits /dev/dsp in Linux and has no comments as to what it does. Make sure that /dev/dsp is available in your Linux install - if not then install oss.compat from your repository.

It needs Python 2.6 minimum, but may well work on a much earlier version

Don't run the code first but have a go at working out what it does and see if you are correct... ;o)

You can email me if you think you are/were correct:- wisecracker_at_tesco.net

Bear in mind I don't think this has ever been done before by hitting the /dev/dsp __directly__.

NOTE:- NO imports are required at all!!!

It runs for about 7 seconds before exiting...

Another BIG PLUS for Linux.

(I have a feeling poeple on here might like this, possibly even vote it up. ;)

Answer now at the bottom of this page...
