1. Software installations required on the remote users computer
2. Using SBHS website
3. Performing a Step test experiment remotely

Pre-requisite

1. Introduction to SBHS and
2. Introduction to Xcos.

These are available on the spoken tutorial website.

Pre-requisite

Scilab can be downloaded from

• sbhs.os-hardware.in/downloads OR
• www.scilab.org

Please note that you will need Internet connectivity to install Scilab.

Or download a portable Linux version of Scilab from links mentioned in the previous slide.

• are written using Scilab 5.3.3
• and is the recommended version.

A higher version of Scilab will work equally well.

However, code modified in a higher version of Scilab cannot be re-used in the lower version.

Now, the next step is to download the experiment Scilab code.

In the address bar, type os hyphen hardware.in

This is the website for opensource hardware.

It will download the Scilab code.

Here it is.

Extract the content of this zip file on the Desktop.

The contents inside this folder, will be discussed at a later part of this tutorial.

• from where one can gain access
• to do remote experiments on SBHS.

An activation link is emailed to the user after the form is submitted successfully.

The link received in the email, should be used to complete the registration process.

Note that the activation process may not be immediate.

It may take a few minutes.

Enter Password

I will enter my username and password.

A slot is the time duration in which you can perform an experiment.

In our case, a slot lasts for 55 minutes of every hour

Book future slot option will always be available.

It will allow two non-consecutive slots to be booked, each day.

The slot booking part is over.

Let us now run a simple Step Test experiment, downloaded from the website.

Do not move any of the folders from their location.

If the directory structure is changed, the experiment will not execute.

If you want one experiment to be copied elsewhere, make sure you copy the common files folder, too.

However, make sure the common files folder is always outside the experiment folder.

Open the file config

This file is used to do the proxy settings.

• You are inside IIT Bombay OR
• You are outside IIT Bombay and using an open network.

For example, at home or using a mobile internet.

• You are outside IIT Bombay and using a proxy network.
• For example, at an institute, office etc.

Change the other details as per the proxy network which you are on.

Save and close this file.

Note that the first time execution of this file will take a minute to open the SBHS client.

It will show various parameters of the experiment like

• SBHS Connection,
• Client Version,
• User login and
• Experiment status

Green dots mean that the sbhs client can connect to the server.

It also shows that the client version I am using is the latest.

User login and Experiment status is red because I have still not logged in and the experiment is not running.

type username

type password

click on login

Type your username and password.

This username and password is the same you used to book a slot.

Click on login.

Ensure that you login on the booked date and time, with correct login details.

Expect the message Ready to execute Scilab code.

If so, open the file manually inside the Scilab editor using the File menu.

It should also open the file in Scilab editor.

Click on Open a file.

Choose the file stepc and click on Open.

The working directory should be StepTest.

If not, it has to be changed using the Change Current Directory option available in File menu.

Type the command getd space dot dot slash common files and press Enter.

On the menu bar, click on Execute option and then click on File with echo.

If the network is working properly, it will open an Xcos diagram.

If it doesn't, it will show error on the Scilab console.

Double-click on each block to change its parameters.

I will put the initial value as 30, final value equal to 45 and step time equal to 300.

Similarly, I will set the fan to be constant at 50% which is the default value.

To execute, click on the Start button on the menu bar.

click on show video

Click on Show video option.

It will give a live video feed of the SBHS you are currently accessing.

I will pause this recording for some time and then resume again.

It will have a folder named after your username.

Read the log file name as year month date hours minutes seconds dot txt

Use this log file for further analysis.

In this tutorial we learnt-

• What are the software installations required to do a remote experiment on SBHS
• How to use the SBHS virtual labs website
• How to use the python based SBHS client application
• How to execute the Scilab code of an experiment

It summarises the Spoken Tutorial project.

If you do not have good bandwidth, you can download and watch it.

• Conducts workshops using spoken tutorials.
• Gives certificates to those who pass an online test
