[Mumbai Heritage @mumbaiheritage]

Good evening from Mumbai.
For a moment, this almost feels like Italy.
But those terracotta rooftops, the harbour and the Taj remind you… this is Mumbai.

@MehdiHacks Wow. ISO or ASA also has an equivalent DIN number. Just remembered after seeing this meter.

@MehdiHacks @eevblog Slightly radioactive 😀

At one point NYC had ~600,000 manhole covers from foundries in Howrah near Kolkata.

People forget Howrah was once called the Sheffield of India. In the 50s it had ~90 foundries and 100s of engineering units packed into an emerging industrial belt.

West Bengal accounted for ~75% of India’s metal casting output and supplied a meaningful share of global demand in the 40s/50s when most of Asia barely had an industrial base outside Japan.

India had the industrial base early. Then came decades of permit raj economics, labor paralysis, socialism, anti-industry politics and infrastructure decay.

Today China produces *half* of global casting output with ~20k foundries producing ~50+ million tons

While Indian cities like Kolkata and Kanpur which had a serious head start are now nowhere near the scale of Chinese industrial cities that were far behind them just a few decades ago.

That difference compounds across everything:
- steel
- shipbuilding
- electronics
- EVs
- solar
- machine tools
- chemicals

One country scaled factories. The other debated them.

Howrah could have looked more like Shenzhen or Hebei or Liaoning today: Advanced Industrial clusters, ports, steel, heavy engineering, electronics and supply chains feeding the world.

@richapintoi Unsettling it is!

The number of full-fledged Free and open-source software (FOSS) products and initiatives coming out of the 4th Phase, JP Nagar (Zerodha Tech), must be unprecedented for a team of its size globally.

All of these projects started as a way to solve problems we faced internally and were then open sourced. We use them at scale in our stack, and several large organisations and even government departments globally use many of these tools today.

Read more, check the website in the comments.

"Turning maker dreams into shareholder value".

How does this create value exactly?
Arduino has raised $54M in three seed rounds, with the last one in 2022 at $22M.
These investors weren't going to sell for anything less than the 9 digit $100M+ range, probably $200M+.
Arduino's core business is hardware, at what, 1-2M units a year?
Run the profit numbers on that, minus hardware cost and company staff overhead (Crunchbase says 250 employees?) and other costs. That's not exactly raking it in.

And how much of this business is still goodwill buying of the "genuine" boards? And how much of this goodwill will remain now that it's just another corporate monolith? How many will just switch to the clone boards?

I give this 12 months tops before corporate get the financial KPI's, and they bring in the hatchet swingers and subscription goblins.

@groby5000000 Happened to me a few times. Super annoying 😡

my boyfriend wants to start a company called “just” and manufacture stuff like a refrigerator that’s just a refrigerator or a washing machine that just washes your clothes and their products have no tech and work for at least 15+ years.

The Insta360 Ace Pro 2 action camera comes with Ransomware out of the box. You MUST give them all your private data to register the camera through the app or it won't work.
I'm sick of this crap, don't buy Insta360 or DJI products. And change your profile picture to a Clippy.

Why buy a guitar tuner when you can build one yourself? Using an inexpensive board and a clever signal processing algorithm, this #DIYelectronics project delivers a precise, real-time guitar tuner that’s both technically impressive and satisfying to use.

On a summer day in 1968, a 26 year old man drove to Weybridge to meet his closest friend's ex-wife and her five year old son, as it just didn't feel right to him that she was no longer a part of their circle.
On the way, he composed a song for the son, all about battling on through the heartbreak to make things better.
He originally called it Hey Jules, for young Julian, and over fifty years later we still sing the chorus in a million car journeys around the world.
Hey Jude, just one of so many masterpieces by a man who understands melody like few others.
Happy Birthday Paul McCartney!

If you’re working on an air quality monitoring project and space is at a premium, SparkFun’s latest Qwiic breakout board featuring Bosch Sensortec’s BMV080 sensor might be exactly what you need. This isn’t just a shrunken-down version of existing PM sensors, it’s a serious performer in an unbelievably compact form. https://t.co/DxDNfZlfbS
