Good bye sir :-)
Will update you once things get off the ground, hopefully.
Have a great day!

Nostalgia
I really learnt a lot and satisfied my curiosity with discussions with you on different physics concepts.
Dec 16, 2022 08:33
Ah that's totally fine sir :-)
The other day, someone in LinkedIn contacted me saying that they were observing and gained useful insights from physics conversation we used to have, and I think he had joined in our college, probably in my junior batch I think.

Currently, everything is in my drawing note. I'll try to convert things into proper CAD and also design the PCB stuff. I'm estimating to take a month or so to completely finish it and keep it ready to fly. I'll try to update it with you at the earliest about the results.

On the transmitter side, since I'm designing it, I thought of introducing "active" control to the joysticks much like the relatively new active control sidesticks.

Incidentally, I also started learning control theory from a course on mechatronics I took this semester.

@JohnRennie Ok sir. Thank you for sharing your opinion. Actually, it's a personal project done just for my own fun and it isn't part of the curriculum. I was in the decision process before I fully commit. But I'm most probably going forward with the project.
Dec 16, 2022 08:18
But sir, there is a problem with this or at least on my end. Even though I'm certain that this project is something I would really enjoy doing, a part of my brain tells that everything in this is tried and tested, like we already have autonomous flight and will it be good enough if I do it as an engineering student? Of course, there will be lots of learnings, but this minor loop of thought process seems to backfire. Do you have any opinions or suggestions on this?
Dec 16, 2022 08:15
@JohnRennie :/
Dec 16, 2022 08:15
@JohnRennie Nice. It's always fun to have some control over mechanical elements with these microcontrollers. In fact, to be precise, I'm also using ESP32 mainly because of its processing speed and cost.
Dec 16, 2022 08:12
And some kid like desires to include gear retraction system, and of course lights :)
Dec 16, 2022 08:12
I'm planning to build a fixed wing RC aircraft, and design my own flight controller for it by designing a custom PCB. I had few ideas which I thought would be cool to see how it works, like using two digital pressure sensors that can be hooked up to an Arduino and calculate airspeed much like how the usual pitot-static system works. There were some more ideas, like implementing an automatic CG calculation system and checking if it falls within the limits.
Dec 16, 2022 08:04
Yes sir. It was quite a ride. :D
Certainly enjoying it on the whole.
Dec 16, 2022 08:02
@JohnRennie That's entirely fine sir. I'm studying mechanical engineering at NIT Trichy :)
Dec 16, 2022 08:02
@JohnRennie That's great :)
Dec 16, 2022 07:59
How are your Christmas preparations going on?
Dec 16, 2022 07:59
My fifth semester exams ended just day before yesterday, and I've just started my winter break, sir :-)

I'm started to do some personal projects, although I feel they are quite simple.
Dec 16, 2022 07:48
@John Rennie: Hi Sir! How are you? It's been a very long time since we talked before.
May 9, 2022 09:10
Good bye, sir. It was nice to chat with you after a long time. :-)
May 9, 2022 09:06
Ah yes :-)
May 9, 2022 09:04
I kind of feel this 20.04 is booting bit faster and is smoother than 18.04. Not sure if it's my illusion.
May 9, 2022 09:04
Just followed our previous conversation for Grub customizer too.
May 9, 2022 09:03
Yes sir. :-)
May 9, 2022 09:03
@JohnRennie: Everything seems to be working great. :-)
May 9, 2022 08:02
Sure sir. Thank you very much.
May 9, 2022 08:01
I didn't want to clean everything off. :-)
May 9, 2022 08:01
That's why I stopped the previous time.

@JohnRennie Yes sir, Windows seems to start normally. And I'm in desktop.
May 9, 2022 07:59
Sure sir.
May 9, 2022 07:59
In the boot manager, it still shows Ubuntu along with Windows and the flash drive. Are we good to go, sir?
May 9, 2022 07:57
Ok sir. Fingers crossed. :-)
May 9, 2022 07:57
May 9, 2022 07:57
@JohnRennie Now, it's successfully unallocated sir.
May 9, 2022 07:56
😐

May 9, 2022 07:54
@JohnRennie I believe that the 127.5 GB partition here is the one we earlier allocated for Ubuntu, sir:
May 9, 2022 07:50
@JohnRennie :-)
May 9, 2022 07:50
@JohnRennie the power off button was non responsive for some reason. It worked after I went to 'try Ubuntu' option sir.
May 9, 2022 07:49
I'll send in 5 minutes. Things just came back to control.
May 9, 2022 07:48
Sure sir. I'm now having a situation with powering off through Ubuntu. :-)
May 9, 2022 07:48
Ah. Got it sir.
May 9, 2022 07:46
@JohnRennie Wouldn't delete volume automatically remove the partition as a whole? I haven't tried it. I thought proceeding via the installer and using the first option work work out. Sadly it gave a warning.
May 9, 2022 07:44
@JohnRennie :-)
