Assignment:

* Watch the relevant KiCad tutorials available at [http://spoken-tutorial.org/ http://spoken-tutorial.org]
* Reproduce the layout of astable multivibrator using '''Oscad'''
* '''Oscad''' uses Kicad for '''PCB''' layout creation
* Footprint editor in '''Oscad''' = Cv'''PCB''' in KiCad
* '''Layout editor in Oscad = PCBnew in KiCad'''

| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.176cm;"| Here is an assignment for you.

Watch the '''KiCad''' tutorials on PCB design available on our website.

Reproduce the layout of '''astable multivibrator''' created there, using '''Oscad'''.

'''Oscad''' uses KiCad for '''PCB''' layout creation.

'''Footprint editor''' in '''Oscad''' is the same as '''CvPCB''' in '''KiCad'''. Similarly, '''Layout editor''' in '''Oscad''' is '''PCBnew''' in '''KiCad.'''

So the procedure to create PCB layout in Oscad will be similar to that of KiCad.

== Data Acquisition using Scilab ==

Data acquisition systems (DAQ or DAS) typically convert analog waveforms into digital values for processing.The components of data acquisition systems include: Sensors, Signal conditioning circuitry, Analog-to-digital converters, Digital to Analog Converters etc. A DAQ hardware interfaces between the analog signal and a PC. The hardware could be in the form of modules that can be connected to the computer's ports (parallel, serial, USB, etc.) or cards connected to slots (PCI, PCI-Express, etc.) in the mother board.

Most of these DAQ hardware work only on Microsoft Windows environment and they require the use of proprietary software and drivers. Here, using a set of Spoken tutorials, we teach you to access these DAQ hardware '''in Linux''' using a FOSS tool called '''Scilab'''. We have used Ubuntu Linux 10.04, kernel version 2.6.32-24. The version of Scilab required is 5.3.0 or higher. This is done with the help of '''HART toolbox''' Scilab. The DAQ hardware used in these tutorials are one among : Advantech PCI 1711, Measurement Computing PCI DAS-1002, Measurement Computing PCI-DDA8/16 and USBDUX FAST.

This tutorial will benefit students, teachers, professionals, entrepreneurs and enthusiasts who use DAQ hardware. At present, these tutorials are useful for over 100 DAQ cards listed in the [http://comedi.org/hardware.html COMEDI Hardware list]. However, this list is growing in number.

The prerequisite for learning these tutorials is the knowledge of Scilab and knowledge of Linux - shell commands etc.

The Spoken Tutorial effort for Data Acquisition using Scilab has been contributed by Rakhi R and Abhishek Pawar from IIT Bombay.

== Data Acquisition using Scilab ==

Data acquisition systems (DAQ or DAS) typically convert analog waveforms into digital values for processing.The components of data acquisition systems include: Sensors, Signal conditioning circuitry, Analog-to-digital converters, Digital to Analog Converters etc. A DAQ hardware interfaces between the analog signal and a PC. The hardware could be in the form of modules that can be connected to the computer's ports (parallel, serial, USB, etc.) or cards connected to slots (PCI, PCI-Express, etc.) in the mother board.

Most of these DAQ hardware work only on Microsoft Windows environment and they require the use of proprietary software and drivers. Here, using a set of Spoken tutorials, we teach you to access these DAQ hardware '''in Linux''' using a FOSS tool called '''Scilab'''. We have used Ubuntu Linux 10.04, kernel version 2.6.32-24. The version of Scilab required is 5.3.0 or higher. This is done with the help of '''HART toolbox''' Scilab. The DAQ hardware used in these tutorials are one among : Advantech PCI 1711, Measurement Computing PCI DAS-1002, Measurement Computing PCI-DDA8/16 and USBDUX FAST.

This tutorial will benefit students, teachers, professionals, entrepreneurs and enthusiasts who use DAQ hardware. At present, these tutorials are useful for over 100 DAQ cards listed in the [http://comedi.org/hardware.html COMEDI Hardware list]. However, this list is growing in number.

The prerequisite for learning these tutorials is the knowledge of Scilab and knowledge of Linux - shell commands etc.

The Spoken Tutorial effort for Data Acquisition using Scilab has been contributed by Rakhi R and Abhishek Pawar from IIT Bombay.
