BLE on dedicated SoCs: a few µA in idle BLE on ESP32: ~35 mA base current For a battery powered product, that’s the difference between months and days 💡 Always do battery profiling before locking in hardware Want to estimate the battery life for your product? DMs are open.


Today, I had a meeting with two talented founders, I am suprised by the product vision. Product is simple yet very useful and yet nothing like this in market. You don’t need to invent but observation can also generate great product ideas.


When you are building electronic products, the onlyperson who can decode your setup is you.

This has huge scope.

This is the power of YOLO, trained on a laptop for ~1 hour, with a Kaggle dataset. Oh, and just ~100 lines of Python. I can make a startup on this and it took me literally a couple of hours.



Agree! Mathematics is beautiful.

The beauty of mathematics lies in patterns and symmetries.

I believe ancient India was more advanced than the modern world.

We were testing OTA updates on 40+ Zigbee devices and suddenly, every Wi-Fi connection around us dropped. Even our router went offline. 😅

No, we didn’t build a jammer.
But here’s how Zigbee became one by accident.

I really thought we’d be at the top. but not too shabby 😅

There is something healing about watching components find their place. Like each resistor and IC knows where it belongs. Just like thoughts settling in meditation.

🔋 Ever wondered why your battery % jumps from 40% → 10% suddenly? It’s not the battery’s fault, it’s your fuel gauge config. Common causes: • Wrong chem ID ⚗️ • No learning cycles done • Temperature compensation ignored • Poor current sense calibration Fuel gauges are…


We are going to use TI's BQ40Z50 in couple of weeks.

⛽ Many engineers treat a fuel gauge IC like a voltmeter. Big mistake. A real fuel gauge (like TI’s BQ series) tracks: • Voltage 🔋 • Current ⏱️ • Temperature 🌡️ • Discharge curves over time It learns your battery, that’s how it knows 20% ≠ 3.7 V. If your product needs…
