| 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 Open Source - 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 the 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 are 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 the 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 |
| 11:12 | How to use the python based SBHS client application |
| 11:16 | How to execute the Scilab code of an experiment. |
