Time
Narration
00:01 Welcome to the spoken tutorial on Using Single Board heater System Virtual labs on Windows OS.
00:08 In this spoken tutorial, we will learn about: * Software installations required on the remote users' computer
00:15 * Using SBHS website
00:17 * Performing a Step test experiment remotely.
00:21 As a pre-requisite, watch the following tutorials- Introduction to SBHS and Introduction to Xcos.
00:29 These are available on the spoken tutorial website.
00:33 I am recording this tutorial on a Windows-7 32-bit Operating System.
00:39 Ensure that Scilab is installed on your computer.
00:42 Scilab can be downloaded from sbhs dot os hyphen hardware dot in slash downloads OR www dot scilab dot org.
00:56 Please note that you will need internet connectivity to install Scilab.
01:01 All SBHS experiment Scilab codes are written using Scilab 5.3.3 and is the recommended version.
01:10 A higher version of Scilab will work equally well.
01:14 However, code modified in a higher version of Scilab cannot be re-used in the lower version.
01:22 I have already installed Scilab 5.3.3.
01:26 Now, the next step is to download the experiment Scilab code.
01:31 Open a web browser.
01:33 In the address bar, type: os hyphen hardware dot in and press the Enter key.
01:42 This is the website for opensource hardware.
01:46 Click on the project SBHS.
01:50 On the left hand side, click on Downloads.
01:54 Click on the download link for SBHS Scilab codes for Windows.
02:02 It will download the Scilab code.
02:04 Save it on the Desktop.
02:07 Here it is!
02:09 The file downloaded will be in zip format.
02:12 Extract the content of this zip file on the Desktop.
02:16 To do so, right-click on it and choose Extract Here.
02:23 The contents inside this folder will be discussed at a later part of this tutorial.
02:29 Now, let us see the SBHS Virtual labs website.
02:33 On the left hand side, click on the link Virtual Labs.
02:37 This is the interface from where one can gain access to do remote experiments on SBHS.
02:46 A first time user needs to register once, by clicking on the Login/Register option.
02:55 After this, a form has to be filled and submitted.
03:00 An activation link is emailed to the user after the form is submitted successfully.
03:06 The link received in the email should be used to complete the registration process.
03:12 Note that the activation process may not be immediate. It may take a few minutes.
03:18 I will now login with my registered account.
03:22 I will enter my username and password.
03:28 After a successful login, a user has access to Book Slot, View/Delete Slot etc.
03:36 A slot is the time duration in which you can perform an experiment.
03:41 In our case, a slot lasts for 55 minutes of every hour.
03:47 After clicking on the Book Slot option, the client will have two choices.
03:53 One can either book Current Slot or a Future Slot.
03:58 Book Now option will appear only if the current slot is vacant.
04:03 Book future slot option will always be available.
04:07 It will allow two non-consecutive slots to be booked, each day.
04:12 I will click on the Book Now option
04:15 You will receive an acknowledgement, with your booking details appearing on the top side.
04:22 The slot booking part is over. Let us now run a simple Step Test experiment, downloaded from the website.
04:31 Open the folder you downloaded and saved on the Desktop.
04:36 You can see that there is a StepTest folder and a common files folder
04:45 Do not move any of the folders from their location.
04:48 If the directory structure is changed, the experiment will not execute.
04:53 If you want one experiment to be copied elsewhere, make sure you copy the common files folder, too.
05:00 However, make sure the common files folder is always outside the experiment folder.
05:07 Open the common files folder. Open the file config
05:13 This file is used to do the proxy settings.
05:17 Do not change the contents of config file if you are inside IIT Bombay OR
05:24 You are outside IIT Bombay and using an open network.
05:29 For example, at home or using a mobile internet
05:34 Change the contents of config file if you are outside IIT Bombay and using a proxy network.
05:42 For example, at an institute, office etc.
05:47 Put the value of use proxy as Yes with Y capital.
05:53 Change the other details as per the proxy network which you are on.
05:58 Save and close this file.
06:01 Open the StepTest folder.
06:05 Locate and double click on the file run
06:09 It will open the python based SBHS client application.
06:13 Note that the first time execution of this file will take a minute to open the SBHS client.
06:21 It will show various parameters of the experiment like
06:25 SBHS Connection, Client Version, User login and Experiment status
06:32 Green dots mean that the sbhs client can connect to the server.
06:38 It also shows that the client version I am using is the latest.
06:44 User login and Experiment status is red because I have still not logged in and the experiment is not running.
06:54 It will also give you an option to login.
06:58 Type your username and password.
07:03 This username and password is the same as you used to book a slot.
07:08 Click on login.
07:11 Ensure that you login on the booked date and time, with correct login details.
07:16 Expect the message Ready to execute scilab code.
07:21 Switch to the StepTest folder which has the experiment files.
07:26 Double-click on the stepc file.
07:29 This should open Scilab automatically.
07:33 It should also open the file in Scilab editor.
07:37 If it doesn't, click on the File menu. Click on Open a file
07:44 Choose the file stepc and click on Open
07:50 Switch to the Scilab console.
07:53 Type the command getd space dot dot slash common files and press Enter.
08:03 Switch to the scilab editor.
08:06 On the Menu bar, click on Execute option and then click on File with echo
08:14 If the network is working properly, it will open an Xcos diagram.
08:20 If it doesn't, it will show error on the Scilab console.
08:25 Using the step test Xocs diagram, we can set the experiment parameters such as Heat and Fan.
08:34 Double-click on each block to change its parameters.
08:39 I will set the heat to vary from 30% to 45% after 300 seconds.
08:46 I will put the initial value as 30, final value equal to 45 and step time equal to 300.
08:59 Similarly, I will set the fan to be constant at 50% which is the default value.
09:08 Now let us save and execute the xcos diagram.
09:13 To execute, click on the Start button on the menu bar.
09:18 If there is no error, it will open a plot window.
09:22 It will consist of three graphs, Heat, Fan and Temperature from top to bottom.
09:31 Switch to the SBHS client.
09:34 It shows the values of current iteration, heat, fan, temperature and time left for experimentation.
09:44 It shows the log file name it has created for this experiment.
09:49 Switch to the browser. Click on Show video option.
09:56 It will give a live video feed of the SBHS you are currently accessing.
10:01 This is a real experiment and will take some time to complete.
10:05 I will pause this recording for some time and then resume again.
10:11 After sufficient time of experiment, the graph obtained is as shown.
10:16 I will stop the simulation by clicking on stop button available on the Xcos window.
10:24 Close the SBHS client window after the experiment is over.
10:29 Now, switch to the experiment folder and open the logs folder.
10:36 It will have a folder named after your username.
10:40 Open this folder and locate your log file.
10:45 Read the log file name as year month date hours minutes seconds dot txt
10:54 Use this log file for further analysis.
10:58 Let us summarise.
11:00 In this tutorial we learnt, What are the software installations required to do a remote experiment on SBHS
11:09 How to use the SBHS virtual labs website
