Very happy to see you making videos again. They were definitely missed.

That was just LOVELY! It also explains why a lot of these adapters work across brands. They use the same chip.

The most underrated channel, and the worst ever microphone. Thanks for your interesting videos!

His rapid mumble speech doesn't help either

Loved this. Going over the linkswitch datasheet while looking to the die was really interesting. Keep it up. Thank you!

Very informative, thank you.

My neighbor thought he wanted eithetnet-over-powerline until his Asian-made hardware caused RFI problems to me. Oddly enough he soon found out that his RFI emitter was also susceptible to RFI ingress. His expenditures were quickly rendered useless!

Every teardown is an adventure in real art.

Awesome format. Love it. Very invormative!

A neighbor worked on some of the core technology behind this. I don't think he made much money, else he would live in a different neighborhood.

It really seems hit or miss depending on when and where you work or invent 😢

Filtering at the inlet to the fuse panel solves this nicely. It's nice to not be bothered by your neighbors equipment.

The metal layers need to be etched off the newer chips with etching cream to see anything interesting

I almost understood nothing but this was very interesting to watch

I do love your teardown videos, if only because you're the only one I know who regularly deencapsulates chips. I was a bit disappointed to see you using binwalk (because it's the same crappy tool I use) until I saw that this firmware is from 2012. Binwalk can definitely handle that

I also had one of these D-Link devices in the mid 2010s. It never worked very well, I suspect because the sections of house we tried to join together were far apart and only connected at the main breaker

The datasheet for the Broadcom chip is available on the internet

This was awesome! Thanks.

excellent video, very interesting device to tear down

Thanks! ❤

These devices work similarly to ADSL modems, except that they send their signal over power lines instead of a phone lines. They use a similar communication technique called COFDM where the signal is sent over many narrow channels instead of one wide channel. As a result, interference will only take out one or some of the channels instead of taking down the whole communication. Also, I was not expecting the Ethernet chip to use DSP technology, but according to the datasheet, even something as simple as a 100 Mbps Ethernet port uses digital signal processing actually.

Hey can you do a teardown of a teardown on that desk lamp with voice recognition that Bigclive did a vid on yesterday? There's a single chip doing the voice recognition with no internet connectivity at all and using mere milliwatts. I just don't understand how such a thing could be even possible with something so primitive.

It is using very simplified sounds chunks recognition. Speech exists out of vocal patterns, and the chip reacts to very crude distinctions.

Agreed, I was about to suggest that too!🙂

Mod those to send the signal on the phone line and you'll basically get the full bandwidth it's capable of.

More Sir!

Small correction: The hostname is most likely just the lab-bar-15 bit, the colon is a separator, and the rest is the path to the binary...

junk box for the win.

Hey friendo, how's that buried Raspberry Pi? (I'm never going to stop asking, unless you ya'know don't want to answer).
