EEVblog + The Signal Path Discussion

[EEVblog]

Dave talks with Shahriar Shahramian from The Signal Path.
This is an introduction and we talk about being Youtubers etc.
This is PART 1
NOTE: Yes I know the video sucks, wasn't much light in there and camera did what it wanted to do.
Yes I know the audio isn't perfect either, Shahriar is a softer talker than me, so I had to run it through The Levellator to even it out.



This part is about the importance of science, debunking, and pseudo science, and education


This part is about the millimeter wave electronics and 5th generation RF

I am going to buy Dave a cat for his birthday 

[Monkeh]

Thumbs up for flat cats.

(I'm a cat owner, I love cats)

[Bud]

Good engineering discussion in part 3, enjoyed it 

[mtdoc]

Excellent discussion Dave 

Shahriar is articulate and thoughtful. A thinker.  And a true teacher and scientist.

I've watched a few of his videos but never subscribed. I need to fix that.

Once Dave experiences the intense cuteness of an extremely cute cat, he will completely change his opinions of cats.

Scientifically speaking, once the cuteness level of an animal reaches a high enough level, it becomes impossible to not like it.

Animals like cats, foxes (including fennec foxes and marble foxes), raccoons, river otters, red pandas, cheetahs, and Netherland Dwarf rabbits, are able to achieve cuteness levels that are high enough to to distort the flow of time as the universe struggles to handle such a large amount of cuteness from a single small source.
Think about it, have you ever seen a single person on earth who says that they do not like those animals and truly mean it?


--------------------

Anyway, awesome video, and I hope to see more long format videos from the signal path. It is hard to find really good long format content, and really, the signal path and EEVblog, and mikeselectricstuff are some of the only channels where you can find that kind of content that is truly informative, interesting, and enjoyable to watch for the entire duration.

Of all the subjects covered in these 3 clips, THIS one gets the most air??

 


On all the other things mentioned - Good job.  I would love to see more with Dave and Shahriar.

I liked Dave's question about an FPGA equivalent for prototyping RF - especially the state of the art stuff. From my very limited knowledge - it seems that in that world, every blink of the eye costs enormous amounts of money. Not just the ASIC fab, but the design and validation efforts that surround it. The test gear is out of this world expensive and the people to take advantage of it are out of this world too.

As the frequencies increase and more data is crammed into a limited space - the cost to develop requires massive sales just to break even. What are the practical financial limits and is it even possible for new players to enter a market with such enormous financial and talent barriers. Do specialty RF devices have to use a derivative of consumer products to amortize the costs?

In digital electronics - FPGA's started life as a prototyping tool but ended up being a transformative technology that has enabled really amazing things. Designers have been able to dabble in hardware design without the insane expense of ASIC development. Small, niche market devices are easy with amazing compute capability. RF seems like it will remain an ultra-exclusive area for development.

first video, 10 minutes in. Lovin it

My two favorite electronics bloggers in one video. Thanks guys!

Perhaps there's not a 97% consensus among engineers (not even those in Oregon) WRT AGW, let's find out, shall we?

Looks like a bunch of people un-subscribed because of these videos 

[CalMachine]

I thoroughly enjoyed the videos! 

And correlation != causation

And correlation != causation

When I've gotten daily negative subs less than a handful of times in 8 years, I'm petty sure it's these videos.

[TheSteve]

Time to teach yourself to love cats.

But ... why?

Wow.. two giant's  It makes me think of this clip:

Part 1: eBay for repair equipment  prices rising after Shahriar's videos- may very well be the case, i myself went and bought a non-working Agilent signal gen after watching one of his repair videos, and repaired it. If it were not his repair video i would most likely not ever do that. But the video gave me confidence and a fairly good idea on a possible troubleshooting approach for that quite complex piece of test equipment.

[EEVblog]

Looks like a bunch of people un-subscribed because of these videos 

But ... why?      

Several likely reasons:
1) They didn't like the "mini-flood" of three videos in a row. If they simply don't like "interviews" then no way it would have gotten this many unsubs.
2) They didn't like the fact that I hate cats
3) They didn't like my opinions on science, debunking
4) They didn't like my support of the AGW theory

Or a combination of those.
In all cases my care factor is zero 

[Electro Detective]

Zero is a bit too generous isn't it?

I've only watched the first episode but I have to comment on the engineers and deadlines reference. That is so me. I can procrastinate until the cows come home, Bob's my uncle or being trapped as a young player, and then finish a sprint to the deadline and sort of get the product out. Have been doing that since attending university in 1980 really.

Is this really an engineer's syndrome/affliction? Anybody else?

I've found it almost universal in the field. Seems to work at both the individual and group levels.
Would love to see a real study on it.

Yeah, a study, that would be awesome!

I've also noticed (as I'm a bit higher up nowadays) that a lot of engineers look at a problem and try to find a solution that makes them comfortable, instead of thinking about the user. Like, just throw a button up there and they'll understand. I have to remind them (and often also myself) about the user actually using the product. Does it make sense from the user perspective? But often this doesn't fit well with the procrastination syndrome I mentioned above.

I admit my perspective is more from the software side - but my approach has been quite the opposite.  I will sit down with users and get to understand what they do and how they want some new facility to fit in.  I question until I have a high degree of confidence that I am on the same page - and then start asking about specific actions, edge cases, alternatives and so on.  I sometimes opened with my philosophy: "My job is to help you do your job."  This served me well.

2) They didn't like the fact that I hate cats
 

Well, you are wrong about cats.
