Energy doesn't FLOW the way you THINK! (Electrodynamics) - Duration: 7:50.How does alternating current even work if the charges never go anywhere?
The answer to this question rearranged all my intuitions about circuits.
Prepare for a mind blow.
This episode was made possible by generous supporters on Patreon.
Hey Crazies.
One thing you cannot do is confuse the motion of charge with the motion of energy.
They are not the same thing.
Let's define them both very carefully.
Electric current, or just current for short, is the flow of positive charge.
Wait wait, positive charge?
Yeah, you can thank Ben Franklin for that.
To the timeline!!
Back in 1748, Ben Franklin stated two things about electricity.
One: Amber becomes negative when rubbed.
And Two: Current is flow of positive charge.
Then, 150 years later, JJ Thomson discovered the electron and we realized we had a problem.
You'd think we'd have adjusted one of Franklin's definitions, but we didn't.
We doubled-down on them instead.
Even though we know negative charge is what moves in a current,
we pretend like it's positive charge moving in the opposite direction.
Human stubbornness will never cease to amaze me.
Anyway, we have to live with it now.
Electric current is the flow of positive charge
and we measure it in amperes, or amps for short.
The energy flow, on the other hand, is best described by something like power.
That's basically how fast the energy is being used
and it's measured in joules per second or watts.
Turn down for watt!
Anyway, current and power are related to each other.
Since current is charge over time and voltage is energy per charge
power is just current times voltage.
It's a relatively easy calculation.
But our original question isn't really about amounts.
It's about direction.
This equation tells us nothing about direction.
But isn't the energy carried along by charged particles?
Won't the current and power be the same direction?
Well, "yes" to the first question, but "no" to the second.
The charged particles do have energy because, well, everything has energy,
but that's not the energy that's powering whatever device you're using.
Let's say, for the sake of simplicity, it's just an incandescent light bulb.
What I'm about to explain will be true of everything,
but we don't want to get caught up in unimportant details.
On that same note, let's power that light bulb using a simple battery.
The positive end has a higher energy than the negative end
so, if you give the charges a path, they'll fall to the lower energy.
That's what an electric current is.
Over time, we know the energy in the battery goes down as we use our devices.
It can cause sheer panic when it's the battery in our phones,
but this same thing happens with the light bulb too.
The energy in the battery goes down as the light bulb emits heat and light.
The flow of that energy is described by something called the Poynting Vector.
No, that's not a typo.
It's named after John Henry Poynting, the guy who came up with it.
It is a pun though because it points in the direction of energy flow.
I love puns.
Anyway, here's the Poynting vector.
E is the electric field, B is the magnetic field,
and mu is just a constant to make the units come out right.
Don't worry too much about it.
That gives us the energy flowing through an area every second.
A common example of this vector is light.
Light is an electromagnetic wave,
a disturbance in electric and magnetic fields that results in a flow of energy.
From a bulb, that's looks something like this.
But the Poynting vector is true for any electric and magnetic fields,
not just the ones you find in light.
What's the deal with those fields again?
Hmm, I guess I can do a quickie review.
Charges affect the electric field and moving charges affect the magnetic field.
These fields are not attached to the charge.
They stay attached to space, while the charge moves.
If no charges are around, the fields are still there.
They're just zero.
A similar thing happens around a battery.
This battery can be thought of as two equal but opposite charges.
Those charges will affect the electric field.
But, according to the Poynting vector, we don't get an energy flow
without also having a magnetic field.
The battery isn't going to lose energy just sitting there.
It has to be connected to something.
Here's the electric field around the battery again, drawn a little simpler.
If we connect some wires and a light bulb, the field will distort a little.
Even though the charge in that extra stuff is balanced,
it still channels the field through itself.
The field in those materials is strong enough to push charge along.
Now that there's a closed loop, the electric field will cause a steady current
and, where there's moving charge, there's a magnetic field.
So now we have an electric field and a magnetic field.
According to the Poynting vector, we get an energy flow.
But this cross product means the flow has to be perpendicular to both fields.
The flow of charge is the same direction as the electric field,
which can't be the same as the flow of energy.
According to Poynting, the energy cannot flow in the same direction as the charge.
Wait, what?!
Exactly!
When I realized this, it broke all my intuitions about circuits,
but here's what everything looked like when I put it all back together.
If we zoom in one of the wires a little,
we've got a strong electric field inside moving the current along
and a little electric field outside.
We also have a magnetic field inside and outside.
Using the Poynting vector, we get an energy flow toward the center of the wire.
The energy comes from the field outside the wire!
Wait! Didn't you say earlier the energy comes from the battery?
Yeah, but it happens indirectly.
Inside the battery, the electric field points the opposite way,
but the magnetic field points the same way.
If we look at the battery the same way we did the wire,
the energy flows out of the battery and into the field.
So the energy the wires and the light bulb gain from the field
is the same amount of energy the battery loses to the field.
The energy flow in this circuit looks like this.
It's cray cray!
It doesn't even matter if it's AC or DC.
With alternating current, or AC, the current just moves back and forth
because the electric field keeps switching direction,
but so does the magnetic field.
If this changes direction and so does this, the two effects cancel.
The energy flow maintains its direction.
Even in an AC circuit, the energy flow is out of the source and into the devices.
How can that possibly be?
Aren't AC generators, like, miles away?
Yeah, but that's totally fine.
Remember these fields are everywhere and affected by all charges everywhere.
The energy coming out of a power source
doesn't have to be the same energy going into your devices.
Conservation of energy just says they have to be the same amount.
If you calculate the amount of energy flow across the surface of this wire.
You will get exactly what we'd expect for the power lost to heat and light.
So how does the energy actually flow in a circuit?
The energy that makes a circuit work comes from the fields around it.
A source of energy like a battery just replenishes what gets used
and all the electric current does is provide the mechanism we need to make the energy flow.
So, are you as mind blown as me right now?

And until next time, remember, it's OK to be a little crazy.
The featured comment comes from "space is where we belong to!" who asked:
Is wind just a little nudge to get the coil spinning?
No no, we're not creating perpetual motion machines.
The induced current actually resists the motion of the coil.
Without the continued push from the wind, the coil almost immediately stops.
Anyway, thanks for watching.

Como Aquaman deveria ter terminado - Legendado - Duration: 5:13.Subtitle: The_legender
Do you think this helmet makes me look stupid?
No.
You
You look totally awesome.
The sea is alive...
with the sound of
Your Death!!!!
Holy Crap!
Oh my dearest, whom I love with all my heart!
now that I had destroyed your house
I must go back and marry the man I originally ran away from
to make more babies
because reasons
or maybe you could just... not do that
You mean stay?
Yeah I mean it took them like what two years to finally find us here.
We could just move inland and they'd probably never find us.
Oh! Okay! Yeah let's do that!
This is a trident!
Don't count the points...
It's... it's a trident!
And you're going to learn how to use it!
Until you do..
Your name is, Shark Bait!
Shark Bait Ooo Ha Ha!
Help him!
He's trapped!
You can't leave him like this!
I'm not leaving anyone!
I'm taking you to jail!
I'm very disappointed in you, son.
I'm gonna need that knife back.
Arthur!
You are being tried for being our mother's first born...
and not caring about our fish ways.
What say you?
I said, What say you?!
I say here fishy fishy fishy!
What the?
Ah! Oh my gosh!
There's too many of them!
What is this place?
It's the ring of fire, Shark Bait!
Shark Bait Ooo Ha Ha!
Hold on! I'm gonna crash us in the lava!
There. Now they'll think we're dead.
Quick! Hide in this whale!
Oh man! They crashed in the lava!
They must be dead!
Well did somebody check the tracking device?
Oh yeah!
Hey it says they're inside that whale right now.
Freeze, Sucka!
Awe Man!
I'm just a dude trying to do what's right.
and if that's not good enough
Then screw you!
If you can take the trident from Atlan's grip...
then you shall be worthy of..
Don't worry. I got this.
What the?!
Because I'm Batman!
Hey hey, Chase! What's up?
Been a long time!
No! No! No! No! No!
I do not accept this!
Well you kept telling that squid monster thing how much you were a nobody...
So I figured...
I'll just take it.
You stole my victory, Bruce!
Hey. What's up?
I'm Batman.
You wanna know my secret identity?
Uh... is it Bruce?
Oh. You heard him say that, did you?
This is outrageous!
You can not wield the trident!
Oh yes I can!
Did you not hear me at the waterfall?
Why are you wearing those clothes?
Did you take them off of a dead person?
Well he obviously didn't need them anymore.
Isn't that like grave robbing?
Oh so if i do it, it's rude.
But if aquaman does it...
It's totally cool.
Yeah!
Just give me back my trident.
The Ocean Master must be stopped!
What for?
Superman can handle it.
Yeah I got this! No worries.
Atlantis! Arise!
Your helmet is stupid!
I knew it!
See?
Justice League bro!
Yeah I thought we started something here.
You can't just be going rogue on us now!
Yeah. Where's Diana?
Where's Flash? Where's Cyborg?
Uh.. I don't know.
Having their own adventures.
Look I'm not going rogue!
I'm having my own origin story.
That also takes place after our team up story.
Nobody wants that!
Justice League, Man!
Hey Hey Aquaman!
Nice one!
You must be so proud!
Se what I mean?
They're devastated!
Could it be that maybe you guys are just a teeny bit jealous?
Whaaaat? No! What! We're not Jealous!
What would we ever have to be jealous about?
That everyone expected Aquaman to be lame!
And I made it look Epic! And Exciting!
No! That's not.. That's great!
Or is it that I single handedly made over a billion dollars?
No!
A Billion Dollars! Congratulations.
So happy for you.
Oh I know what it is.
There's really no need to explore this.
It's because both my parents...
Are still alive.
How dare you!
And their name's aren't Martha.
Ooooh It's True! Oh it hurts!
It's true!
Why would you say that?
I lost both my dads!
We both don't have our parents!
I still have a mom!
Kind of.
But Aquaman has both of them!
It's so not fair!
Yeah!
Permission to come aboard?
AAGH! Too sexy!
EEGH Too Sexy!
AAAGHAAA Too Sexy!

Favourite YouTube Channels, New Art Books, Supplies + More - Duration: 15:50.Hi my loves! I hope you are all well. As the title suggests, today I wanted to
share some of the things I have been loving recently. I've done videos like
this in the past where I've done like hauls and favourites but with this one, I
wanted to have less of a focus on things- like things that you need but don't
really need- and more of a focus on things of real value, or things I
consider to be of real value anyway, and maybe spotlight some talented creators
and I don't know a share some things of real inspiration I think you guys would
love. So to start with, I'm going to do the biggest category and that is
some youtubers that I really enjoy watching.
Now I'm not gonna mention anyone that I have mentioned before, but will have a
pinned comment down at the bottom, just of all of my favourite YouTubers
who I've mentioned in the past and, then anything else that I mention in
this video will be linked in the description along with timestamps for
you to be able to skip along to your heart's content. But we'll start
out with the category on art education. There are so many fantastic
teachers on this platform with their own areas of expertise and their own varying
points of view and approaches and I think it's really important to diversify
the amount of lessons and just the different types of information that we
take in. So I recently discovered this video (literally yesterday) in my
suggested called 'How Social Media is Ruining your Art' and it's by a creator
called Adam Duff and he- I mean- I quickly
realised on discovering his channel, an incredible teacher. He's a really
knowledgeable, also really down-to-earth guy and he has this wealth of lessons on
his channel for aspiring artists and also for any professionals in that field.
'Well you're an artist...'
'You're providing to your audience something of quality. Quality
takes time, quality takes concentration, quality requires trial and error, so if
you are gonna keep up with that rat race then you have a choice. You can either
wait, take your time...'
If nothing else, I think you guys should all watch this
social media video because it rings true to a comment that I get so much on this
channel from people who feel like they're discouraged by the lack of
attention that their work is getting on social media. This video really spoke to
me and I think it's just such an important thing for all of us especially
in this age of making art and posting it on the Internet. Another fantastic artist
and teacher who dedicates their time to sharing their knowledge on this platform
for free is Marco Bucci. He posts maybe once a month but it's such important,
fundamental stuff and broken down in a way that's so easy to digest and so easy
to go and practice straightaway. I just feel like there is so much that you can
learn from him. I know I said I wasn't gonna mention people that I have
mentioned before but I just had to give a shout out to Robin Sealark.
I love her videos, I find her so fun and captivating. She has a real free
approach to art, also a real discipline and a commitment to improving and
sharing that with her audience. 'Now I want to compartmentalize my time better
and make sure I'm being well-rounded in finding meaning in a lot of areas of my
life and making new goals....' She likes to
approach things as a challenge. She's not afraid to pinpoint things that she wants
to change or improve in her art and she really encourages that in her viewers
and I just always find I leave her videos wanting to go and make something.
Jared does some really fantastic gouache and watercolor demos that are so calming
and relaxing to watch that you don't even realize that you're learning as you
go along. There's a level of understanding behind everything he does
which he explains so clearly as he goes along but he's also not afraid of
imperfection and trying things even if he's not sure if that's the way to go.
Now I know nothing about oil painting but this is what I mean when I say that
we need to diversify the sources of information that we have because there
is so much of value, there's so much that is relevant to me on Andrews
channel. He is insanely talented but he's also very open to
sharing the process behind his art and also the journey he's taken to get to
the level of talent he's got right now. You know, rather than that myth of just
naturally being good, you can see the practice and the work that he's put in
and the years. And I also just love his videos
to see all those beautiful landscapes that he surrounds himself in. Another oil
painter, Cynthia hasn't posted in a little while but she has a really great
backlog of videos that hold so much value. She's another one that just seems
so real, so down-to-earth, and also very transparent with her process and the
thought behind her work. '...and that way, you can see exactly what your lights and
darks are doing without the color. Ultimately you still want your piece to
be readable either way so let's do that here, let's take a look at how this
painting breaks down when it's converted to greyscale...' She just strikes me as
someone that has a really kind heart and it also really knows what they're
talking about. Alright, next category is studio vlogs.
I know you guys love seeing behind the scenes of artists and I personally love
seeing how that day-to-day varies so much from one artist to another. Right
I've been watching Joy for ever and I am constantly in awe of the amount of work
that she puts in around her job, her constant innovation and creativity, the
products that she's making, the storytelling, her art style... just
everything she does- I'm just in love! I find her so relatable and hers are the
type of video that I save for when I really need that kick up the butt to get
productive and get some work done. She really spurrs me on to want to make
things. Catherine is another insanely hard worker. I love seeing the behind the
scenes of how she creates and sells her products from coming up with
the concepts and actually creating them and then getting them up for sale,
photographing them... all of that! She's so transparent with that process and I
think that's so useful for aspiring artists and illustrators. She really
shows the realness and the hard work that goes in behind the scenes of being
an artist. Plus she has the most infectious personality, she is like the
embodiment of a ray of sunshine. Okay random fact that's kind of boring but I
love names that end in 'ica', like Erica, Monica, Danica... so I loved Sarica's channel
even before I'd watched her videos. But I discovered her during vlogmas
and she's another one of those people that really draws you in with a warm and
welcoming personality. She's also crazy talented, she mainly does journaling
videos which I know you guys will love, but I also really enjoyed her vlogmas
as well again seeing that behind the scenes of what she does and
how she creates products and stuff like that. Another channel I find really
motivating even though it's in a different kind of art area to what I
would normally be into, that being like conventions and OCs and stuff like
that, is trickywagon. It's another great and different perspective into the
life of a freelancer and products they make and their process and obstacles and
again another really relatable and down-to-earth creator.
Okay the last of my favorite YouTube channels are less art specific but more
channels I turn to for that creative boost and inspiration. It's really great
to consume different media and find inspiration in different places than
just pure art. So the first one is kind of art-related. It is the Baumgartner
Restoration channel. You probably have seen this in your suggested, I've
seen his channel like skyrocket since I subscribed I think he's gained about
200,000 subscribers in like the last month but for good reason. This guy, he
just really carefully and beautifully restores these old paintings he does his
videos just with sound, with the sounds of his studio and the work he's doing
but he also will then re-do the video with a voiceover and you get to hear
just the intricacies of that process I just find it's so fascinating and so
immersive to watch. I just love this channel- the main reason I'm making this
video is because I wanted to mention this channel- I would really
recommend at least watching one of these videos because there's a real art
to it. Okay similar in the creative and
peaceful use of sound is this channel that I can't pronounce. It's a vlog
channel, mainly focused on food I find. There's also a really cute puppy.
But yes, kind of just day-to-day life, no talking, just that ambient noise and- I
don't know- I find it really calming, beautifully shot and great sound
design. Nowness is an interesting one. I don't watch all their videos, I think
they posted every day so some of them are a bit hit-and-miss for me, but I do
like the way they produce their videos. I like just seeing different
artists and different areas and different crafts. I really like
this series that they have that's called In Residence where you get to go inside
of the most beautiful and unique houses and just hear them being spoken about in
a way that's so poetic. The videos just in general are short and artsy and for
some reason, they always just make me feel like I want to create.
And finally, and a little bit of a random one, is fairyland cottage which is a
channel that is kind of about living more sustainably, making things yourself,
respecting and being more a part of nature and relaxing and slowing down and
being more mindful. Niamh has the most calming and warm personality, the most
gorgeous voice and accent, the way the videos are shot is lovely... it's
like a warm bubble bath, watching her videos. Or- I don't know- a hot drink on a
really cold day. Okay, so next we're onto books. The first thing I wanted to
mention is the one I mentioned I think in my 'getting my life together' blog
where I was talking about setting new goals for the year in small achievable steps.
The book is called 'One small step could change your life, the Kaizen
way' it's by Robert Mauer and it's a really concise ,quite succinctly
written, a quick and easy read. Just easy to digest, easy to take actionable steps
afterwards which I always like in those kinds of self-help books and I think
it's a great one for this time of year where we're all looking to
have a fresh start and improve in some way. It's really helped me reevaluate how
I approached my goals and I'm feeling a lot more capable this year and a lot
more hopeful to really take those steps one tiny little increment at a time to
becoming the person I want to be. Okay so JAW Cooper is an artists I'm sure
you all have heard of or at least seen some of her art. She has this beautiful,
fluid, quite natural style that's also- it can be quite almost disturbing, quite
gross and distorted at times. It's just this gorgeous combination of the
grotesque and the beautiful and she recently came out with a collection of
books compiling her recent work. I got this one. This is
Visera. There's a collection of the three books. I really
wanted to get my hands on all of them, this is the only one that I could get my
hands on at that time. And yeah it's just full of really beautiful quality images
of her work, her sketches, some finished paintings and it's a great insight into
her mind as an artist, and it just feels like such an honour to be able to see
that side and be able to see the background behind some pieces of art
that I'm sure you would have seen before. It's a book that I find myself
constantly reaching for when I need that visual stimulation and just a great
snapshot into the mind of an artist- a really talented artist. And in general,
it's just a really beautiful quality art book. So the next book is a book I
received in my PO Box a couple of days ago and this is Book Love by Debbie
Tung. I've already read it front to back, it's basically a collection of comics
about the love of books. I know you guys will love this. Just really
quirky and funny and relatable little comics about bookworms and book life
struggles. The next one is one that's been in my Amazon wishlist for so
long just because it's one that I constantly see being recommended by
professional artists as a kind of guide to get you started in the freelance
world and it's 'How to be an illustrator' by Darrel Rees sent to me by Polo so
thank you so much Polo and thank you for everything! I know I say it a lot but
really, it means so much to have your support. It's been constant and just
unwavering so thank you. And thank you for this, I can't wait to give it a
proper read. I've had a good skim through it and it's just it seems so full of
really useful information so if you guys are looking for kind of a guide to how
to be a professional in this field then I would really recommend this book. So
since we are now on the topic of my PO Box, I will do a few little bits and bobs
I've received over the last few months. It's been a little while since I've done
a PO box unboxing and the main reason for that is with the move and everything
going on, I've got a lot of stuff here there and everywhere. I also would really-
if you do send me anything please give me a way to contact you either
through email or through Instagram because I don't get to show everything
and I would love to be able to send you a message at least to say
thanks. But to start off with, really striking print from Julie Celina,
it's just gorgeous colours, fantastic work. She also sent some of the most detailed
pencil work I've ever seen and this gorgeous original painting of me which
was such a fantastic treat so thank you so much Julie Celina. I will have links as
always to anyone I mentioned in this video, I know you guys will love having a
proper look at these people and their work, so please do go and spread the love
and show them the same support that they've shown to me. Next up is this
really awesome print from Nastasia of an artichoke. I love this graphic style, I
also love the paper that it's printed on. I just- there's something
about the simplicity of this and the use of line weight that just really speaks
to my soul, so thank you so much for this Nastasia! I've got some really cool work
from Faye who was written before so thanks so much for getting back in touch.
Her artwork has just come leaps and bounds since she last messaged me so I'm
so impressed and so proud, it just really looks like she's been consistently
working on improving her art and it really really shows. Even the envelope
that she sent the letter in is beautifully adorned so thanks so much
Faye, lovely to hear from you again. I also received this inktober zine from
Buzzy and a great letter to go along with it. It's always lovely to hear from
you Buzzy so thank you! I love the theme of this zine and just the quality of
work is really something special so thank you! Also got these stickers
from Deandra. These are so cute, you guys have got to go and check out her-
I'll leave her Instagram, I think she has an Etsy shop as well- you've gotta go and
see if you can get your hands on some of these stickers because they're awesome.
And thank you so much for your letter Deandra, I love the little doodles on
here as well. And finally, something I've been really waiting to share with you
guys; I was so lucky to get my hands on Mel Chadwicks little collection of
Porthleven sketches. So this is like a book of postcards made up of some
drawings that she did of the town I believe that she was living in at the
time, I don't know if she still lives there. Mel I watch on YouTube anyway so it was
so amazing to just receive this out of the blue. I'll leave a link to her
channel below. She does great vlogs as well and just beautiful artwork. I love
the style, I love her use of water and line as well so I'm so grateful to
have these. I kind of wanna send them out to people as
postcards but I kind of also just want to keep them for myself. Another cool
thing in here is this 'ten ways to cultivate a sketchbook habit' little
pocket guide where she's got all these little tips illustrated as well. I just
think she's incredibly talented. She also does interviews with creators. Her
channel and her artwork in general are such fantastic resources and I
definitely would recommend that you check her out. But other than that, I
think that is it for this video. If you have any suggestions, any people that you
want to shout out down below, I would really love that. I think would be great
to use this comment section as a place to really share and promote the people
that we think deserve it. And as always make sure you check out the description
for any links to anything you might be interested in. Make sure you go out and
spread the love and I will see you soon for the next video. Bye!

Blue Compass VS Rode PSA1: Mic Boom Arm Comparison + Light Stand + Camera Stand - Duration: 5:35.<music>
Everybody is loving the new Blue Compass and how sleek and beautiful it is.
But, is it better than the Rode PSA1?
I'll show you 3 features where the Compass is indeed better than the Rode PSA1
one of which nobody is even talking about!
But the Rode has one feature that might make all the difference for your setup!
I am Everson and this is Geek Detour.
<tango music>
Hum… how did I let it happen?
I was happy with my Rode PSA1 Boom Arm…
but I was seduced by the new Blue Compass…
then, the weirdest thing happened:
I kept my old PSA1… and even bought another PSA1.
I am a simple man, but somehow I found a good reason to use all three boom arms.
After you watch this video,
tell me in the comments if it makes sense or if I lost my mind!
So let's see which is the best boom arm for you,
beginning with the Blue Compass:
why on earth the box is so big?
Take a look!
Oh, it is because the Compass comes completely straight inside the box.
This is actually good, and less funny…
I mean,
it won't break any monitors.
<glass breaking, woman screaming>
I swear there were a few videos on YouTube, but they disappeared!
On every review I watched on YouTube,
you have people saying that the Compass has a nice build quality,
that the cable management is simpler and better,
and it looks way cooler on camera than the PSA1
and I agree.
But there are other 3 reasons why you might prefer the Compass:
1st: the Compass is taller than the PSA1.
Let me put them side by side and take a look.
The PSA1 reaches further horizontally,
but the Compass goes higher.
So If you use a big monitor, that might be important to you.
2nd: since its base is just a cylinder,
the Compass takes less space on your desk.
I don't know about you, but, man, to me every inch counts!
Take a look how much more space the PSA1 takes for its rotation!
So that's another point for the Compass.
and 3rd: is a feature that nobody is showing!
The beauty of a boom arm is being able to
position the microphone any way you want by just moving it.
Effortlessly.
<"wrong" buzzer>
You shouldn't need to be constantly easing and tightening the friction thumbscrews…
It should remain stable in any position.
So, what do you do if your microphone is too heavy
or too lightweight?
On the Compass, you can fine tune the spring tension using this hidden screw!
It is mentioned on the manual's text,
but no pictures…
My current microphone is the Blue Spark
and the Compass had the springs a bit too tensioned for my taste
So I loosened the screw just one full turn
and the arm balance got just perfect,
even with the friction hinges completely loose.
But there is one thing that I completely hate on the Blue Compass…
and I really love on the Rode PSA1:
the angle you set for your microphone remains the same,
no matter what you do with the arm!
Actually, the entire purpose of the Scissor Arm design
is to keep pointing to the same direction,
regardless of what you do with the arm.
It might look old fashion, but it is incredibly useful!
So, if you need the "parallel motion linkage", the Rode PSA1 is your choice.
And that is why I kept my old Rode boom arm, and even bought a second one.
But I don't use them for microphones anymore!
One of them is now holding two LED light panels
they weigh almost twice the maximum recommended capacity
so, this is completely not-recommended and very experimental.
So far, it is working fine.
And the second PSA1 I bought to hold my camera.
To do that, I recommend using a ballhead.
The super cheap ones are fine to carry a GoPro,
but they can't handle the weight of a DSLR Camera.
The Joby Ballhead for Gorillapod is not that expensive and handles the weight perfectly.
My Canon weighs about the same as the Blue Yeti + Shockmount + Pop filter,
so I know the PSA1 will be able to handle it perfectly for years to come.
I also tried to mount my GoPro on the PSA1… and… well, you can do it
but the GoPro is too lightweight.
To make the arm remain on the positions I want,
I have to add the weight of a powerbank, with velcro tapes.
You might say "why bother?"
"Aren't tripods good enough?"
Well, I have tripods…
but they are not as flexible and fast to adjust
even more if you do lots of overhead shots.
Also, my "studio" space is quite limited,
and now our baby girl is walking all over the house
so we want to use the table more and leave the floor as free as possible.
If you liked the idea,
in the description I will put links for all the items I used for my YouTube setup.
The Blue Compass has a very modern design.
But the Rode PSA1 remains a work horse
that you can use also for lights and cameras.
Which is the boom arm of your choice?
Let me know in the comments and thanks for watching!
