Teardown Tidbits: D-Link Power Line Adapter

A quick 10 min video which touches on the interesting bits found in a teardown of a D-LINK Power Line Adapter. (DHP-308AV).

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

[@matt.604]

His rapid mumble speech doesn't help either

[@cadbury204]

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

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!

[@dosgos]

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.

[@AnnaVannieuwenhuyse]

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

[@1kreature]

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

[@piconano]

Every teardown is an adventure in real art.

[@VideosGonzalo]

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

[@1kreature]

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

[@EngAlperDemir]

Very informative, thank you.

[@BGTech1]

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

[@mckryall]

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

[@mckryall]

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

[@terminatorcyril]

I almost understood nothing but this was very interesting to watch

[@eugene3d875]

Awesome format. Love it. Very invormative!

[@Muonium1]

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.

[@AnnaVannieuwenhuyse]

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

[@user-bx7ow7wy8o]

Agreed, I was about to suggest that too!🙂

[@atmel9077]

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.

[@BGTech1]

The datasheet for the Broadcom chip is available on the internet

[@seanwagner6870]

excellent video, very interesting device to tear down

[@AdamChristensen]

Thanks! ❤

[@adamcordingley2572]

This was awesome! Thanks.

[@wimwiddershins]

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...

[@ronaldredman8122]

junk box for the win.

[@NiHaoMike64]

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

[@spacewolfjr]

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

[@electronupdate]

Experiment discontinued, no further information.

[@spacewolfjr]

@@electronupdate aye (Happy Canada Day btw)

[@objection_your_honor]

What branch of engineering to become a mixed signal chip designer?

[@spicemasterii6775]

What's the data rate?
