explains about the inertial tensor matrix. today vinod came. Nithin me also there. The bluetooth module needs to be configured or the bluetooth module is not working? It pairs. So, our assumption is it should work. Again, the only way to really make sure things are ok on the ANDROID and the ARDUINO side of things is toread the thesis make notes etc etc.

12th dec

Eye problem. Woke up at 6 couldn't see clearly, eyes watering continuously. Slept for 15 minutes same problem. Then with drops slept for an hour. Still same problem. Went to the doctor, and, found I had an allergy cum infection etc etc So, didn't go to coll and give keys to Nithin. I have to go on thirteenth. The VLSI exam is on 18th and the M&I is on 21st. Help me Shri amma Bhagwan.

http://code.google.com/p/amarino/downloads/detail?name=SensorGraph_02.zip must work the problem there was this. We should've done this-

int sensor=A5 //pin name for Bluetooth TX to the ARDUINO RX
in the loop
void loop()
{
Serial.begin(9600);
}

 Never realized that this was to send the data value from arduino to android. Sry.
Tomorrow, am writing and understanding the code of the amarino app from the thesis for six hours 6:30 to 12:30. By 1:00 will leave for home. By 3:30 will start unit 3.

to configure your bt module you have to connect rx to rx and tx to tx, then you can use the serial monitor to turn your bt into command mode ($$$).

in normal operation mode pins must be rx to tx and tx to rx.

Dec. 9th

Have started work on matlab simulation. Using keyword patch to generate five circles that act as wings of our Penta- Copter.  Also working on doing the re exams. So will be a bit long. Will go to college tomorrow. Told Nithin that we needed multilead wires. Nithin understood that it was just normal house copper wire late at night. My fault. Anyway tomorrow shd work out ok.

Dec 8th

http://www.zilogic.com/contact.html this place can help with the ARM kit to work. The cost of the course is ridiculous at 12500Rs. I just need to find out if the place can make our kit work.

Went to ECE-B gettogether for PT'S and Shiwani's B'day. Started at 12:05 and really screwed up as in drove for 1 and a half hours on a half hour road. To a place called Triana on Lloyd's road. Discovered the difference between RK salai, Lloyd's road, G.N. Chetty road, Gemini flyover, went to marina. Was in a state of constant tension. Luckily, thankfully, I had friends like Santosh who told me to wait at the Indian Bank on the Music academy junction and guided me to the place(I was about to leave.)

Anyway, what that meant was that a day was not spent on the project. When I returned home at 7:15 I realized that we needed multilead wire to solder on to the Bluetooth module. So, there wasn't much use in going to college. Then, another problem

 

Why weren't we able to get the data transferred from our mobile to the ARDUINO2560. This can be understood by understanding what variable we want to display on the serial monitor.

 

 

 

Dec 7th

Today, did a host of things. The things that we did were the following i.e. me and Nithin. This guy Vinod chose not to come. Did not tell me why.
Today was weird. I had a bath and was about to start when I didn't realize where I left the penta room keys. I was searching for ten minutes. One of the most frantic searches that. Then, I realized that I really needed to go to college. This was at 6 42. Then, I ran to the bus stop. Finally, I realized that the bus had left. Then, I came back home, went about a frantic search for the key. I emptied the table. and found it wasn't there. I had serious issues. I was trusted with the key. And then, I... this really happened... I found the key in my wallet. So, it was safe. And, I'd missed the bus. And, there was a missed call from Nithin. The guy reached college at 8. And, then I started for college.  In the middle of when I was driving, he phoned and told me that we might need an SD/Micro card. I was halfway through to college. Luckily, we didn't need it. Drove to it. I found out the cell phone I was given was an S-6312. Because there was no charge on the cellphone for the penta, used mine. It turned out to work. I took home the AT91 board to work, and Nithin wanted to put the software, AMARINO app on the penta cell phone, but he didn't use his own id and made me use mine. This was not strange.
Over in college the following was done.
3. Meanwhile, make sure that the HC-05 module works. i.e. see about what this guy talked about- Suriyanath. He was the guy who said that you could program the HC-05.
4. See that the HC-05 module works with the given mobile phone.
 5. Install all the stuff required for the AMARINO app to work. i.e. just make it work. see if I am able to get the readings at the end of it.

7. solder the Bluetooth module onto the arduino board. THIS did not work out too well. We, Nithin and me tried soldering the thing together. It did not work. The wire kept falling off. It was, I thought that it was because of the use of the wire i.e. it was thicker?? than the stuff on instructables.com.

I got the AT91SAM7S board from Ma'am. The amarino app etc. was installed on my cell. Not on the pentacopter Cellphone. Nithin gave me the sheath for the solder rod. The guy is wow!!.

1. Make the motion model of the pentacopter. This will be done on Monday. Not after following Andrew Gibiansky's blog. But the intech paper that I found.
 2.  Write the motion model of the pentacopter in C.
1,2.a. is derive the moment of inertia of the pentacopter.
1,2.b. is find out the mass of the individual things.
1,2.c. is find out whether the weight measurement machine is still there.
1,2.d follow the steps given in the intech textbook. See. how things work.

9.  See if the AT91SAM7S works on the software available online at home. i.e. ask ma'am's permission to get the at91 board home.
This and CT's lectures will be done today. At home. Apart from that, am also writing the sops and finishing the college applications.

Set of things to do.
Another thing that I have done is get the HC Verma Concept of Physics-1 from L.V.Renga.  1,2.a. should be solved.  Should start on two things today.
1. Watch CT's lectures again. Make notes again.
2. Get AT91SAM7S to work.
Spoke to Suryanath and found that you need to use multilead wire to get the Bluetooth module RX,TX, VCC and GND wires soldered.
3. Solder the wires onto Bluetooth module.
4.  Write the motion model of the pentacopter in C.
 

plan for 7th december

It's the sixth today. Am going to review on all the goals that I have set. Right now, spoke to nithin, he said he 'might try' to get the sheath to solder as mentioned on the blog on as mentioned on November 3rd. Will upload a pic once he brings it. or not. It's 7 0' Closk now. It might not be possible for him to go at night. What are the long term goals.
Well, I started on the matlab implementation of a model. Will hopefully finish it tonight.
1. Make the motion model of the pentacopter. This will be done tomorrow after following Andrew Gibiansky's blog.
2.  Write the motion model of the pentacopter in C.
3. Meanwhile, make sure that the HC-05 module works. i.e. see about what this guy talked about- Suriyanath. He was the guy who said that you could program the HC-05.
4. See that the HC-06 module works with the given mobile phone.
5. Install all the stuff required for the AMARINO app to work. i.e. just make it work. see if I am able to get the readings at the end of it.
6. See and document what I understand from the Cyril Stachnissji's lectures. i.e. what is the next step from there?
7. solder the Bluetooth module onto the arduino board.
8. Compute something like this.
 Initial percentage fo the battery=100%
Final percentage of the battery =x%
((100-x)/100)(1/time taken)= discharge rate of the cell battery while having Bluetooth link with the penta.
9.  See if the AT91SAM7S works on the software available online at home. i.e. ask ma'am's permission to get the at91 board home.
10. Start implementing the control loops for each part in C.


Seriously, if any of you guys are reading this, a like would be appreciated!

Phoned Nithin, he said he got the solder sheath, which means I have to pack the soldering rods in the bag. Both. Done.
