👋 Hi, I’m Anil. I work on safety-critical automotive firmware, microcontroller drivers, and functional safety. Outside of work, I’m exploring Linux kernel internals, device drivers, ARM and RISC based systems, networking, and Edge AI through hands-on learning. This account is my engineering notebook—sharing what I learn, lessons from automotive software, and connecting with people who enjoy building systems from the ground up.

Visiting again. #Bosch

Nowadays I spend more time on x than Instagram it seems.

@Ritesh_Yadav_14 Well +1 then.

Never thought I'd be this close to 500 followers. ❤️ Appreciate every single one of you.

@Sousinr +1

Started this account 3 days ago. Today: 150+ followers.🚀 Next goal: 1,000 by the end of the month. Posting every single day. Let's see what consistency can do. 👀

@Ateendriyo Yeah

#Pune peoples: one urgent question. Once it starts raining, does it not stop? Sincerely, A new arrival.

@Mahindra_Auto Does this even make sense?

If you’re in Pune, please stay safe. 🌧️ Looks like the monsoon is making up for lost time by dumping its entire quota at once! 😅

While building a minimal initramfs, one thing finally clicked: The Linux kernel doesn’t magically give you a shell after booting. The kernel executes /init, which eventually starts BusyBox. BusyBox then provides the shell and many of the familiar Linux commands. Tracing that boot sequence made Linux feel much less mysterious.

@TheOneLanceB @smbcapital Interesting observation. It reminds me of embedded software—AI can make you faster, but only if you already know what “correct” looks like. Otherwise, it’s easy to mistake convincing output for a good solution.

IF CLAUDE/AI IS SO USEFUL, WHY ARENT PNLS GOING UP? I just made an important point on the @smbcapital call. You can’t go a day without reading tweets about traders using Claude. For 6 months now, Claude has been the talk of many trader calls. Yet from what I’ve seen, it’s not translating to pnl for most traders. Why? Because almost always, more data and information is NOT the constraint. The traders that outperformed in April did so because of their systems and execution. It isn’t that Claude and AI shouldn’t be used or isn’t at all useful. But AI and Claude can become a distraction AWAY from the actions and changes that actually matter and translate into PNL. If I were a betting man, Claude might have improved workflows for traders, but net, it has probably reduced trader pnl through distraction away from what matters.

I initially thought building the Linux kernel would be enough to boot Linux. It isn’t. You also need a userspace. Building a minimal initramfs with BusyBox was the point where it finally clicked that a booting Linux system is much more than just the kernel.

If you’re starting with Linux kernel development, I’d definitely recommend beginning with QEMU. I first came across it while following @_streetdogg’s Linux videos. Building the kernel, BusyBox, and a minimal initramfs, then booting them in QEMU, made it much easier to understand the Linux boot process before moving to the Raspberry Pi 4B. If you’re getting started with Embedded Systems or Linux kernel development, I’d highly recommend checking out Pyjama Cafe. I found it to be a great resource for building a strong foundation.

@amit_code Congratulations

Today I hit 16.6K followers. 🎉 Two years ago, I started posting with no expectations. Since then, it has led to: → Thousands of meaningful conversations → Incredible opportunities → 100+ genuine connections → $3,000+ earned through X

One thing I’ve realized while learning Linux: On an MCU, I was used to thinking in terms of peripherals and registers. With Linux, the first question is often: “Which kernel subsystem owns this hardware?” It’s a small shift in thinking, but it changes how you approach driver development. For those who moved from bare-metal/RTOS to Linux, was this your experience too?

Before working on automotive ECUs, I never gave much thought to what makes one MCU different from another beyond performance and peripherals. Working with safety-certified MCUs changed that perspective completely. You start looking at ECC, lockstep execution, fault diagnostics, watchdogs, clock supervision, and the Safety Manual as integral parts of the overall system design—not just hardware features which lists additional safety measures required to be implemented by user to meet Automotive Safety standard like ISO26262.

@Punitwts @X Wow, help me as well :)

Less than 24 hours ago, this account was at: • 3.5K impressions • 83 followers By this morning, it had jumped to: • 39.7K impressions📈 • 141 followers🥹 • 496 engagements🤝 That’s the thing about @X : Sometimes it feels quiet… until suddenly it doesn’t. Still early, still learning, still figuring out what works — but this kind of momentum has me genuinely excited. Grateful to everyone who’s followed, replied, liked, reposted, or even just stopped by. You’re part of the early story now 🤝🚀

It was very rough landing by the way. #Airindia

Looking out of an airplane window today, I couldn’t help thinking about the amount of engineering behind what’s happening. Aerodynamics, propulsion, embedded systems, control algorithms, software, materials, manufacturing… Years of engineering come together so we can sit back and think it’s just another flight. #Bengaluru

@jaiswal_adt Agree

@Anil_Embeded depends on person to person i guess

Unpopular opinion: Instagram is the most addictive app.

Ever wondered how a microcontroller switches a high-power load without getting fried? Here's a simple but powerful circuit that does exactly that — using a MOSFET as the bridge between logic and load. Here's how it works: When the microcontroller's output pin (PA0) goes HIGH, it triggers the MOSFET gate through a 220Ω resistor. The MOSFET switches ON, completing the path to ground and energizing the relay coil — flipping the contact from NC to NO. When PA0 goes LOW, the MOSFET cuts off, the coil de-energizes, and the relay snaps back to its default NC state. Two small components do a lot of the heavy lifting here: → A 10kΩ pull-down resistor keeps the MOSFET firmly OFF when no signal is present — no floating pins, no false triggers. → A flywheel diode clamps the voltage spike generated when the relay coil collapses — protecting the MOSFET from a potentially damaging kickback. It's a compact, reliable design that's become a staple in embedded systems — anywhere you need low-power logic to command a high-power world. Simple concept. Endless applications. #EmbeddedSystems #Electronics #CircuitDesign #Engineering #Microcontrollers #HardwareEngineering

@ptrschmdtnlsn It’s fascinating to see how the boundary between traditional MCUs and application processors keeps getting thinner. A few years ago, PCIe on a microcontroller would have sounded excessive. Now it opens up some really interesting possibilities.

Absurd, we're entering a world where microcontrollers have PCIe. I mean, it kind of makes sense, as PCIe gen2 only needs 5 GHz LVDS, and its wifi has a 5 GHz fundmanental, so the packaging is already rated for it. But a 5 Gbps serdes is non-trivial! I really hope it's hackable.
