I build and write on products.

Looks simple. Isn’t.
> Each TWS earbud contains:
> Bluetooth audio SoC (RF + DSP + power)
> MEMS microphones (2–3 per earbud)
> Precision speaker driver
> Ultra-small Li-Po battery
> Antennas, sensors, dense PCBs
👉 This is miniaturised systems engineering, not an accessory.

@brahma_4u Was thinking about this today morning. Interesting to discover. So few though.

@prakdadlani What makes a good, better or best mould? Iterations? Operator Craftsman ship?

[Sandeep Patil @ExploreEmbedded]

One client had a QC bottleneck. The production output was high but the QC requirements were stringent. Any misses would result in rejection at client end.
Had done a deep dive and gave a through proposal for solving it with high FPS cams. The deal didn't close but I'm thinking if this should be done regardless.

@brahma_4u Routers, Robots, Volumetric Weighing machines and developing many more products that are currently being imported. We are ODM based out Bangalore and Belagavi. https://t.co/Gvj3rNco5v

@brahma_4u @bhash Why isn't it being done right away? No money in repairs?

[Sandeep Patil @ExploreEmbedded]

@brahma_4u @bhash So what's the plan of action. Test battery. Then do cell level repairs or replace the full pack? Is testing the bottle neck?

[Sandeep Patil @ExploreEmbedded]

@brahma_4u After reading this, I was looking at ECU teardowns. The ECU PCB + PCBA + Base Drivers are very much doable.

Full firmware integration with engines, sensors and actuators with broader ecosystem needs big R&D spend.

@suyogvyawahare @Siddhant__rao what needs to improve on quality side?

[Sandeep Patil @ExploreEmbedded]

@Siddhant__rao @Arjun449344 what simple things do Indian mfg miss out on? Let's keep costs aside for a moment.

[Sandeep Patil @ExploreEmbedded]

@maahirpanchal That India can't complete on high volume products.

[Sandeep Patil @ExploreEmbedded]

@prakdadlani If you need good SDK, extreme low power performance nRF is good. CH is cost effective alternative; more work on SW sude. Have done several BLE products. Happy to help.
Flutter should be quick to cross platform apps. Go native if app experience needs to be top notch.

[Sandeep Patil @ExploreEmbedded]

@prakdadlani We are doing it

[Sandeep Patil @ExploreEmbedded]

@prakdadlani Happy to contribute. I can fly down for these teardowns.

[Sandeep Patil @ExploreEmbedded]

@prakdadlani and other expert members in mould making and plastics: Why there is so much dependency on China for this? What areas do Indian makers need to improve on?

[Sandeep Patil @ExploreEmbedded]

@FI_InvestIndia @grok Zing didn't make it to the AI Summit.

[Sandeep Patil @ExploreEmbedded]

@1shankarsharma had the same experience last time. Won't be surprising at least for 3 more years.
