haha! i am just starting up. will see how the journey goes. thanks for the heads-up about analouge circuits

>1. The motor demo didn't work for me (Firefox on Android). Nice to say it was made by Claude.

oh! i did tested on firefox with different devices on my laptop. but not in actual android phone. thanks for flagging it

>2. Voltage isn't like gravity. It's literally called potential. Voltage is the water being high up on the mountain. Gravity is the gravity, which was kinda the point of the analogy, no?

yeah! my bad. i might have wrote few things when i was just reading up and writing as i am trying to internalize what all these things mean

>5. PWM wasn't explained right here. You can most certainly vary the voltage without PWM, and it's not just any old modulation you want. You want a binary output so your transistors don't go linear, and you can control the average power. PWM is easy for linear scaling. But you could presumably use other modulations.

there are probably 10 more ways to make voltage dance - and i only read about two. one is resistors and other is PWM.

>Would be good to understand what the power chain is to make sure nothing blows up.

The blog has link which points to exact wiring instructions including adding buck converter. again! the purpose of this blog is not to explain every bit in detail. it's about what i have learned - because before doing all of this - i had zero clue about everything


I don't think you understand the point of PWM then which is ok. A resistor wouldn't provide runtime control of the power going to the motor, unless you had a programmable resistor which would likely explode from the current induced heating. And that's fine, because everybody just uses PWM, but if you do a follow-up I recommend investigating why the motor is connected and controlled in the way you did it.

yeah! voltage is not gravity. i might have wrote that in my flow.

i think AWS is using pgactive to sell "Aurora Postgres Global" https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide...



Incredible. How does that work? I thought Nitter was completely neutered a while ago.


Nitter worked by signing in with special "guest accounts" that I think were given to fresh downloads of the mobile apps.[0] Last year, X fully disabled that functionality, which left most Nitter instances broken. At that point, the developer publicly abandoned/ended the project.

The couple of instances floating around that still work are, to my knowledge, forks of the original Nitter that have been upgraded to work with a pool of manually created X accounts, which is a relatively expensive and fragile approach that most instances probably aren't up for taking.

I have been on HN since last 10 years.

This community has inspired me to learn and build stuff – just for the heck of it.

I just wish you folks all the happiness and strength in the world.

Happy Thanksgiving ♥
