Here is the final project :

• Source code


• Project report


• Installation guide

Our work was over on 9th June but the professor made us stay..

So... At last I announce that OUR PROJECT IS COMPLETE!!!!!!

Here's the screenshot :

These are just some of the initial images ;) ...

Today...
For the first time we saw values change in the monitor with us changing a knob in our hands!!! (instantaneously)
We plotted the graph of the actual and observed readings.. IT WAS BEAUTIFUL!!! Here is the attached pdf file for download.

We made a prog for querying C with MySQL and integrated it with PARAPIN.

Mr. Pandit told us to ponder more on the diode circuit problem he gave us.

Then..
I decided..
The following approaches are available for giving the data to the JAVA-APPLET:

1. To digitally sign the java applet to allow it make connections to other hosts.
2. To use the tomcat server to make the MySql queries for the applet and ask the applet to connect to tomcat server on port no 80. (The applet is allowed to make connection only to port it was called from.)
3. The 3rd approach.. (My original approach :)
   To use AJAX to update the data on the client!!
   The APPLET tag on the webpage has a parameter named PARAM.
   My theory is -
• As the PARAM tag is on the html webpage.. JavaScript will have full access to it.
• JavaScript has full access to make network connections.
• The JavaScript can make AJAX requests to the web server and update the PARAM tag.
• I will make the JavaScript call for a PHP page which will in turn query the MySql Data.

Today we successfully interfaced parallel port buffer through C.

We started the day late as usual.Vidyadhar Kamble, who was to give us lab equipments had gone on leave and was supposed to return on the next Monday. Then the lab was in hands of Vinod who was quite (damn) unhelpful and refused(!!!) to give us equipments till Vidyadhar returned. So, we went back to our lab and asked Mr. Pandit for help. He pulled out a couple of boxes and arranged for resistors, capacitors, LED's and gave us a CRO, signal generator and power supply. The fat guy (IIT final year placed in INTEL doing his final year proj.) had taken all of our earlier equipment and wasn't even working on it.
We then went to Prof. M. B. Patil and got three ADC's from WEL. The WEL lab in charge was Mr. Joshi who was most helpful and gave us a book to photocopy about interfacing the ADC804's and the much needed single strand wires. We soldered PP connector to single strand wires and connected it to the buffer IC. We tested the ckt and it worked like magic. Our only point of concern was the 40mA current taken by the buffer which increased sometimes on connecting to the computer.

Moreover we also made a Tomcat 5 server servlet query a MySQL database.

Today is Sunday.
We decided on Friday that we'll be going to Pune.. We reached Pune at 11 P.M. by bus..

On Saturday..
We brought all our clothes to Pune to use Isli's washing machine to wash our clothes. Turned out his washing machine hadn't been used for 3 months :P . We spent an hour cleaning his washing machine. When Sahil washed his clothes in the washing machine.. and returned after 15 min, the water had turned darker than slum water.(Yuk!). Put his clothes in one more round. Same with Sumit.
Then we went to Deccan road. Had a Pizza for lunch. Sahil purchased 'Men are from Mars, Women are from Venus'. Had some fun at McDonald's.
We came back home, had ice-cream, had chinese for dinner along with Austin Powers I (awesome night!!).

Today..
Caught bus at Kothrud. Sahil had to stand half of the way coz no seats were left. Reached hostel around 2 P.M. had samosas AND went to the department. Was a rough day. Had nice food in canteen.
