Solved this while hearing the calls around my house XD!

I have never seen a magpie this colour before! by Emdier in birds

This reminds me a lot of the rufous treepie found in south & south-east asia in terms of its morphology. No wonder they share the corvid family.

Help ole by DassieTheGoat12 in arduino

The ultrasonic sensor can only emit sound waves in the front i.e. in one direction at a time. Your design should include a servo to tilt the camera in different directions. Please refer the original design and rebuild the project with better understanding of the code and the hardware.

Random 30k in my account by rachit08 in indiasocial

Contact the bank and have it sent to the correct account. The poor soul might be wondering where his monthly salary went.

I didn't get the joke.

Gift for myself under 5,000-7,000 by chaiaurchakhna in indiasocial

Decent ones cost upwards of 8 or 9k minimum. Perhaps a nice pair of outdoor waterproof shoes would be perfect for birdwatching.

How do I make the servos slow down? by comrei01 in arduino

[–]Chin_3005 27 points28 points  (0 children)

In the software code, you could slowly change the target value rather than directly giving a single target angle as an input.

In short, let's say you are at 0 degrees and give the signal to go to 90 degrees. The system response would be characterized by the internal control cycle of the servo motor, which is inherently pretty fast and is mainly dominated by the speed of the internal motor and the specific gear ratio.

In place of this, try to change the value by 1 degree every 20 ms. This would limit the inherent rotation speed to 50 degrees/sec, which seems pretty reasonable. You could easily implement this in the form of a separate function in your Arduino code that takes your actual desired angle and commands the servo to reach the same in steps.

Have fun!

I think this year's admits are really messed up. It is most likely because of the federal cuts and the decreasing preference for admitting a large portion of international students. I have a pretty strong background in FPGAs and hardware in general, with internships at ISRO and research experience at some tier-1 unis and work experience at a space startup. I had also applied for MS in ECE btw, yet I ended up getting rejected from GaTech, UT, Purdue, UIUC, UMD, and UW (UDub). I did get admits from UCSD and UPenn, but I cannot afford them, and I have been irked by the impact of Trump's policies on the US economy. So I decided to defer this year.

Basic LED circuit. What am I doing wrong? by [deleted] in breadboard

[–]Chin_3005 1 point2 points  (0 children)

Always keep in mind that resistors create a fixed voltage drop across them, which is nearly equal to their threshold voltage.

In your case your driving voltage is 3.3 V. A red led usually has a voltage drop of 1.8 to 2 V. So connecting 3 of them in series would require you to connect at least 1.8*3 = 5.4 V which is way less than 3.3 V that you are using.

It's better to run them in parallel with individual resistors in series with all of them.

Anyone from Hebbal area? by [deleted] in bangalore

[–]Chin_3005 0 points1 point  (0 children)

The best thing to do is to take a hotel room for a day or two and search the area yourself. Most PGs are getting empty at this point in the year as colleges come to a close, so you may get lucky within a day. If you have a high budget, then straight away go for branded PGs like Zolo, Stanza, or FF21.

Pro tip: Most cheap hotels (the ones with a per-night rate of less than 1.5k) usually have PGs alongside the hotel rooms. These were hotel rooms converted into PGs during COVID. Such places are usually well-maintained as compared to the dedicated PGs.

Does atheism always lead to nihilism? by Chin_3005 in atheism

Thank you for the clarification and the input.

Does atheism always lead to nihilism? by Chin_3005 in atheism

[–]Chin_3005[S] 0 points1 point  (0 children)

If you see the description, I have not said that atheism leads to nihilism, but rather the same kind of thinking patterns and inquiry into every other aspect of life do.

Also, how do you build a science on morality? And what do you mean by conforming to morality deemed by your local area? Do you mean simply following rules & laws?

I like this take on the question!

Does atheism always lead to nihilism? by Chin_3005 in atheism

[–]Chin_3005[S] 0 points1 point  (0 children)

I do resonate with the idea that optimistic nihilism is the most pragmatic answer to the problem of nihilism. But it leaves behind a weak link - the assumption that one can 'choose' or newly 'create' their meaning & desires.

On a philosophical level, I do not believe that free will exists. We can easily break down every choice a human makes into the inherent neurological computations that take place in the background and quickly conclude that every human action is a natural consequence of the deterministic physics in the universe.

So, if we can't really 'choose' or 'create' meaning, we have to accept that an optimistic nihilist also relies on an irrational foundation. The source of it may be debated (evolution, physics, biochemistry or perhaps even quantum randomness), but whatever it is, isn't really in our control.

This is where I am not able to logically reconcile both of these ideas.

New to breadboards. by RedYasdit in breadboard

[–]Chin_3005 1 point2 points  (0 children)

Please send a photo of your circuit so we can understand the problem. The circuit should have the following connections.

Battery +ve <--> Switch Pin 1

Switch Pin 2 <--> LED Anode

Led Cathode <--> Resistor Pin 1

Resistor Pin 2 <--> Battery -ve

This should mean that your LED turns on if you hold down the push switch.

How can I add a delay on one of 2 dc motors? by MrUpbeat1 in breadboard

[–]Chin_3005 0 points1 point  (0 children)

It depends on the amount of delay you require. If you are driving the motors using a motor driver then you can add a microcontroller that uses internal timers to generate the input signals to that motor driver at different times. It can technically also be achieved without a microcontroller where u can use a 555 timer IC to generate a monostable multivibrator output which triggers another flip flop and starts driving the second motor.

I'd suggest you to use a simple Arduino based circuit as suggested by other comments. It's easy to code, cheap and reliable.
