It's simply that his presentation style is more love or hate than
most. I always suspected that it appealed more to Americans, as they
more often tend towards exaggeration more than other major English
speaking cultures. For me the result is that I can quite enjoy
similar videos by Mike Harrison (mikes electric stuff), but I just
can't hang in there with D. Jones.

It's similar to that American show on 7two called "Mysteries of the
Underworld" or something equally ridiculous. The places shown are
often (though not always) very interesting and historically
informative, but the hyped up presentation
is so bad that I've never been able to sit through a whole one. At
the same time it's been going for a while now, so obviously a lot of
people are drawn in by the hype.

Give it a calm monotone commentary and excessively long cuts and I'd
find it most enjoyable, while 90% of the audience falls asleep.


It sounds like we have quite a bit in common then. I could have written
that. Thanks for the heads up on Mike's Electric Stuff, I'm heading off to
check him out now.

Hi,

most of you know former regular on this NG, David L Jones, who
reinvented himself as a video star with his EEVblog site. I
stumbled on one of his many hundreds of blogs recently - please
take a look.
https://www.eevblog.com/2014/04/10/eevblog-601-why-digital-oscilloscopes-appear-noisy/

The blog attempts to explode a "myth" about analogue and digital
scopes in relation to display noise - particularly that DSOs are
inherently noisier. While I am not sure just what Dave is trying to
prove, some of his
assertions are very dubious. The facts are that an analogue scope
normally has a sharp trace
revealing a great more detail of waveform being viewed. This is
also a direct result of having: 1. Constant bandwidth ( 20,50,100MHz )
plus the same rise time at
all sweep speeds. 2. Continuous vertical screen resolution of around 1
part in a
thousand. 3. Absence of any artefacts due to sampling or quantising.


All this results in an accurate display of any continuous signal,
including random noise. The clean trace shown on an analogue scope
with no input is because there is no noise to be seen. FYI: This might
seem at odds with an input impedance of 1Mohm and
bandwidth of 50MHz which has a calculated thermal noise of almost
1mV rms - with regular peaks over 4mV. The simple answer is that
1Mohm is in parallel with 20pF, so the impedance falls steadily
from 8kHz onwards down to 160 ohms at 50MHz. Thermal noise is
reduced by this to about 15uV rms. The random noise spiking seen in
the traces of the DSOs in the
blog is mainly due to quantising errors plus the discontinuous,
vertical screen resolution of only 200 pixels in case of two of
them. When the sampled value falls between pixels, random toggling
occurs. Lastly, when Dave turns up the brightness on his Tek 2225,
you see
the trace thicken ( due to mutual repulsion between electrons in
the beam ) and also some background pattern appears. The background
pattern is in the CRT's anti glare screen, which
lights up when you do that revealing any imperfections in the
plastic. He should have detached it. Also when he uses the digital
camera, the image becomes over
exposed which again results in trace thickening. The story about
"revealing missing noise" is a furphy. BTW:

In the first few second of this blog on the Tek 2225, Dave seems
to contradict himself. https://www.youtube.com/watch?v=8GR_6QH3uZk




At the end of the day he may make some mistakes (who doesn't) but to
give him credit he's build a large following and has probably
contributed quite a bit to folk learning more and doing more around
electronics. His forum is very active, aus.electronics is dead. :(


** AFAIK, EEVblog Forum posters are predominately Yanks and it's
moderated by Dave himself as the "administrator".

I haven't done a head count but the mix seems pretty even, plenty of
Aussies.

At the moment, I have no great wish to join up and suspect I might
even be barred anyhow. OTOH, David L. Jones can appear here any time
he cares to.

Bah! Just create a nym.


It seems odd that one would find fault and start a post on Usenet
about it.

** Not odd at all, the topic itself is very interesting - Analogue
V. Digital scope performance is red hot, debatable stuff these days.

I still keep my old Philips analog CRO around, it's good for some
jobs.

BTW

Do I detect a hint of " I *heart* Dave " going on ??

Not really he's entertaining and seems motivated by the right things.
My voice is like his, hence me not doing videos....


Heh! A wise man. Wink

Thanks, though actually I'm pretty right for videos. As far as YouTube
videos go I really only check for new videos once a month or longer,
and by then Mike H. has usually put up another one or two, which is
all I need. In fact we're surprisingly in sync, often after a month
or more I'll check his videos and he's uploaded some just a few
hours ago, and after not checking for a couple of months (when I
got his last videos fresh off the press) I notice now that he's
put up a new one only six days ago.

In any case I've got quite a collection of obscure junk to play
with, pull apart, and reverse engineer in real life. Watching
videos about it instead is really just pathetic lazynes. :)

She seems to like that soddering.
I have only watched 10 minute so far but will get back to it.
