Video Title: Review of the New Bus Pirate 5

I’ve occasionally thought it would be useful to have a Bus Pirate for quick-and-dirty peek/poke and protocol analysis of modern communications over busses like SPI, I2C. I’ve hesitated because the Bus Pirate 3 is distinctly long in the tooth, but the Bus Pirate 4 “upgrade” can’t do as much as the Bus Pirate 3.

When the Bus Pirate 5 was announced a few months ago, it seemed to be a definite improvement - so I took the plunge and ordered one. It has just arrived, rather late due to a manufacturing cockup. Kudos to the supplier for being open and honest, and offering alternatives. If only all manufacturers were like that.

Anyway here’s the box. Not very pretty, but hey, I’ve never thought Apple’s “delightful box and unboxing experience” to be worth much. I just want to use whatever’s in the box.

So, here it is connected to my computer.
    <video of bus pirate, cable, monitor: 15s>
Oh dear dog, those blinkenlights. Got to find a way of turning those off ASAP; they are so bright they are making it difficult to see the BP5’s screen.

Oops, need to do a bit of configuration to udev. Don’t know what would be necessary on Windows, since I’m not clever enough to know how to use that safely.
    <video of finding and typing in configuration: 60s>

Let’s see what it can do. Need to use LED mode, obviously
    <video of typing a few commands: 60s, including correcting typos>

It works!!! I can change the colour of the LEDs and turn them off. Isn’t that pretty, and good value for money.
    <video shows lights changing: 15s>

OK, back to the starting mode. Aargh. Those blinkenlights have rematerialised. Must Turn Them Off ASAP.
    <video of using help command, finding config, trying it, turning LEDs off again: 60s>
Back to starting mode, and they stay off. Excellent!!!

It looks like I can use it as an oscilloscope, so let’s see how good that is. The specification says it is a 500kS/s scope with a maximum 5V input.
    <video of paper specification: 15s>

Now my edge generator has a 5V 50ohm output impedance with a 250ps risetime, so if just connect it directly to the Bus Pirate inputs with dupont jumper leads, the overshoot will damage the input. To avoid that I need to use an inline 50ohm terminator, which controls overshoot and reduces the voltage input to 2.5V.
    <video of attaching pulse generator and inline terminator and getting the scope working: 180s>

Yes, that too works!!!!

Hey, this really looks good. I can recommend it to everyone

<Fade to black>

Overall that contains around 450 words, so speaking normally at 60 words per minute would take 9 minutes. But realistically I’m not a good speaker used to reading a script, so the ums, ahs and gaps might extend the talking head time to 12 minutes. The video of the operation and results are likely to take an extra 8 minutes, since I’m probably not going to be very good at talking and simultaneously operating the equipment. I’ve also got to reattach connections, and move the camera between shots, so that will probably add 1 minute. The mandatory Google video adverts will add 120s. All in all that is maybe 20 minutes long.

I reckon that video would take me 30 minutes to shoot on a smartphone, and at HD resolution it is the odd 1GB or so.

So, what do you think? Should I do it?

Which of these channel names do you think would be most appropriate?

For the avoidance of doubt… None of the above applies to content creators who take the trouble to edit the footage, who create a table of contents under the video, and who do more than simply open boxes. Unfortunately such content creators are very much in the minority.

I imagine a Jerry Walker style intro section - and a clean-starched-shirted presenter 

[thm_w]

I wouldn't over think it. Name doesn't matter to me.
The rough script you laid out looks good, screencap some use of the software and show the board up close and I will definitely watch.

You underestimate the filming time, IMO.

I don't know Jerry Walker, but it wouldnt be a clean starched presenter.

As my daughter once said with a strong tone of incredulity, "I didn't know you had an iron!" . I pointed out that I had owned it longer than I had owned her.

I might even wear a 50yo T-shirt, but I could sell it for a surprisingly large amount of money. FFI, spelunk in the TEA thread

No, that time is about right.

Everything that would be in the video is explained above.

Here's a picture of the board, with blinkenlights.

I too ordered the Bus Pirate 5 (I once bought a Logic Analyzer designed by Ian Lesnet, so I knew the BP5 was going to be a decent device for the low cost!). I, too, didn't understand the LEDs and felt they were unnecessary, but in real life, admittedly, it does look intriguing with the LEDs pulsating! - And there's a chance they could be handy for quick status details if they are programmed for that.

In terms of features, I wish its adjustable output voltage feature was not linked to the logic input voltage level since many (say) 3.3V logic circuits require a different supply voltage to run (e.g.) 5V.

The main reason I was more interested in BP5 than previous versions is that it's using the RP2040, which has a quite decent C/C++ SDK that I'm familiar with. I'd be interested in maybe adding some software features someday.

Regarding videos, I can't comment on what's good or not in terms of content, sometimes it resonates with viewers, sometimes it does not (I create the occasional video, but generally niche stuff, I do not turn on ad revenue etc, so that hopefully any viewers don't get adverts). However, on a practicality thing, personally, I find it hard to talk to the camera without many um/ahs, so I only know of two solutions:

(1) Keep the video very short (for me, that's about 3 minutes max!) to reduce um/ahs to a tolerable level
or
(2) Edit the video. With the bonus that the edited video can be reduced in length to remove additional uninteresting bits at the same time.

Here's some general stuff that I've found helpful, it's just a personal opinion of course; I'm sure plenty would disagree:

(a) No need to say what's in the video if it is obvious. For instance, no need to read out lines of content, if that detail is already being displayed on the screen.

(b) Worth taking plenty of snapshots at the time you take the video, in case you later need to fill some speech space with photos (perhaps some of the video recording was no good or blurry, so at least you have a photo to replace the video for that section)

(c) Regarding demonstrating to a spec, while that's interesting to some, personally, I'd be interested to instead see real-world examples (if possible), e.g., seeing how BP5 is used to capture I2C from a real sensor.

(d) A wall of test equipment (some Youtubers do that!) is hard to work into videos because it seems like visual clutter. It is nicer to see the testbed in more detail instead, covering the entire video frame size.

An example of unedited video. Plenty of errors, like the important part of the mobile phone display is off the screen at times. But at least it's short (3min 37 sec), so viewers do not have to put up with um/ah irritation for long either.


An example of edited video (mostly all um/ahs gone, but also importantly all boring bits removed, and as a result the video is  short at 3 min 20 sec).

[SiliconWizard]

That's funny, but I still think that anyone who makes the effort to shoot videos and upload them, however clickbaity or worthless they are, is still eons better off than the ones who are merely consuming said videos.

AI auto-generated videos aside, there's definitely something to that sentiment, in that for sure it's a tough thing to do, no matter how terrible the result might look to everyone else. Some skills take ages to learn. I cannot do 'off-the-cuff' videos, I have to prepare a bit, whereas for others it's maybe more natural.

Some things are subtle. For instance, while I absolutely need to write notes or a script, what's written doesn't always flow well in a video. A script to be spoken aloud can sound different from what would read better in a forum or blog post, so some thinking is needed on the fly to decide what to skip out from the script, where to pause or emphasize a bit, etc.

Another issue is that preparing a script might still not be good enough for flow. Most decent videos will be story-boarded first, so that's yet another step that would ideally be learned to identify what messages to convey in the video and then the best way to get there.

Execs, when key-note speaking at conferences, apparently, allocate a whole day per slide that they talk over. So, just 5-slides-worth of video should really take up an entire full week of prep! Just not feasible for a typical YouTube video.

I hate blinkenlights, marquees, and anything similar that distracts from the content.

The status details are pretty well (and clearly) defined on the LCD screen next to the connector, and also on the VT100 display. As they stand, I'm not aware of then being useful for anything other than eyecandy. I expect that writing your own C code could make them more useful.

In terms of features, I wish its adjustable output voltage feature was not linked to the logic input voltage level since many (say) 3.3V logic circuits require a different supply voltage to run (e.g.) 5V.

My attitude is that the programmable voltage is useful for the IO voltages. I would normally use an external PSU for an external device, but if I can power that device then it is icing on the cake.

The main reason I was more interested in BP5 than previous versions is that it's using the RP2040, which has a quite decent C/C++ SDK that I'm familiar with. I'd be interested in maybe adding some software features someday.

I suspect if I wanted to do something like that, I'd first try to export the datastream up the USB to a PC. If I want to do post processing, I want a decent environment where I don't have to use C/C++ except for poking registers. "Decent" implies statistical processing, filtering, graphing, (etc) and not being constrained by whatever time/space is left available in an MCU.

Regarding videos, I can't comment on what's good or not in terms of content, sometimes it resonates with viewers, sometimes it does not (I create the occasional video, but generally niche stuff, I do not turn on ad revenue etc, so that hopefully any viewers don't get adverts).

or
(2) Edit the video. With the bonus that the edited video can be reduced in length to remove additional uninteresting bits at the same time.

That is clearly unfashionable, and not something valued by today's audience. Evidence: all the new videos pushed at you on youtube.

The most important thing is to get close to livestreaming the "real life experience" of using it. That means the video cannot be shortened or edited. Clearly that is the case, as evidenced byall the TV shows like "Big Brother", "Love Island", "Gogglebox", etc - which clearly captivate the new generation. Curiously, those were largely anticipated by the famous 1968 production "The Year of the Sex Olympics", and to a lesser extent the 1976 movie "Network". FFI, see gurgle.

The old rule of thumb of taking an hour to post-process a minute of broadcast video is so "last millenium".

That's all so last millennium. Off-the-cuff opinions and instant on-the-spot reactions are so important to keep the action and money flowing - just look at all the "front page" videos on youtube. If I don't follow suit, I'll lose out.

[shabaz]

You could fight the power! : ) Network was a great movie. I've not seen Year of the Sex Olympics but just saw on Wikipedia that it was written by the author of the Quatermass movies, so I will definitely try to watch it at some point.

What people find interesting is inexplicable for sure. I have difficulty understanding how kids enjoy watching Youtube videos of people playing Minecraft, for hours on end. Sometimes making them watch something completely different works and absorbs them though, but their natural instinct will be to watch Minecraft : (

[Sredni]

My suggestion to you is to work on the thumbnails. Boobs work great.

No, seriously, I have put up a few horrible demonstrations of a simple circuit that have close to zero views (I have four 'subscribers' and I know them by name :-) ), but the ones which have a piece of paper with formulas scribbled on it as a thumbnail are close to have negative views.
The ones with the scope, or some electronic gear in it get a few dozens views from random strangers, probably by people who think there could be something imteresting to see (and by the time they find the skip button on the screen the video has ended and the view number has increased by one).

Work on your thumbnails.

[hans]

I think it very much depends what kind of video style you want to chase.

30min for such a format sounds to me like a low-budget shoot with minimal edits. That's OK, but it wont attract masses. Given that YT has quite a hefty watch-time threshold to get monetized, I wouldn't expect to make any money from it unless you're upload with a regular schedule for months to years.

I've certainly thought about doing something similar, but still haven't found the inclination to do so. The trouble for me is I'm a perfectionist and I absolutely cannot stand 'mistakes'. I know that those quirks are the things that people will love and attach to. But I also want the things I say make sense and match with what's on screen. I disagree that uploading 'anything' is better than just consuming.. uploading misinformation is probably worse. Mistakes aside

So given those things, I wouldn't expect such a video to be a quick 30min shoot. You want to prepare your technical work. You need to realign camera gear. You wrote this script. You need to get a good film environment: good sound, lighting, framing, etc. You have to shoot A roll, and if really dedicated, B-roll. You need to piece together this puzzle in editting to make a visually entertaining video, up to whatever standards desired. Certainly I don't have time to "watch" a video with poor audio or long pauses to show trivial information. I hate to say it, but for that reason I don't watch many EEVblog videos start-to-end anymore, because of time. There is simply so much entertaining channels that can squeeze fun stuff <15min.

BUT, as I eluded before with the stuff I've done before , you've got to start somewhere and then build up.
I certainly wouldn't plan on the first video being some kind of endgame. Start simple.
And I don't run a YT channel myself, so: [/my 2 cents]

[tggzzz]

you might want to look at the old masters like Oprah and Jerry Springer to get maximum audience

Certainly not! I have standards.

Several sets, actually, so I can choose between them

[coppercone2]

[tszaboo]

Don't overthink it, just make it. You are probably going to get less than 100 views, and it could take a year of constant release with disappointing results before your channel would get any traction. And by that time you either learn how to do videos, or you give up. Use a very good quality microphone, people will instantly leave if the audio is bad. Or if you have a foreign accent like me.

[Bud]

No shaking camera FFS.

[rsjsouza]

But... But... But... I though you thought all Youtube videos were useless?!?

Jokes aside, just release something out to the ether with good audio, good lighting, a camera sitting on a tripod so it doesn't shake, a good video editor and plenty of time to acommodate shooting the video and editing it.

After releasing a few videos and re-watching them, make a decision on the direction and style you would take.

Good luck and welcome to the marvelous jungle of youtoob.

How about MoreUselessVideos?  It seems your script doesn't include any actual testing. When doing a review, I work according to a test plan (crafted to verify the instrument's specifications and beyond) to go through the functionality and limits of a piece of test equipment. For an oscilloscope that means a couple of days work for doing just the tests. Along the way the testing also provides a good feel of how the instrument operates and where the UI is good or bad.

[shabaz]

Regarding camera on tripod, although I agree, just to play devil's advocate, some manufacturers prefer short product reviews to be done with a mobile phone, slightly shaky being OK, because that's 'keeping it real', i.e. seems a more authentic genuine review, than a polished presentation. Perhaps that works well for short 'how-to' videos sometimes, for particular single features, or a quick 'unboxing' (I don't usually watch those, but they are occasionally helpful to get a quick overview of what's going to be supplied with the product).
Also, sounds superficial/cruel to say, but this is also why, even for official videos, they prefer to choose someone that they believe looks average rather than good-looking.

Why the "  "?

It seems your script doesn't include any actual testing. When doing a review, I work according to a test plan (crafted to verify the instrument's specifications and beyond) to go through the functionality and limits of a piece of test equipment. For an oscilloscope that means a couple of days work for doing just the tests. Along the way the testing also provides a good feel of how the instrument operates and where the UI is good or bad.

It doesn't have any testing. It is an the feeling of unboxing and getting it to work. I'm trying as best I can to fit into the zeitgeist of modern youtube.

Mind you, I'm having trouble with the config experience being real-time and staying within the set limits. Currently I've spent several hours pissing around with the udev filters, without success. I've had some suggestions on the BP5 forum, but so far they haven't panned out.

There are two USB interfaces, one text the other binary, and it is pretty random which one minicom (terminal emulator) connects to. The workaround is to connect the terminal to /dev/ttyACM0; presumably the binary interface is /dev/ttyACM1.

While the syntax of the udev rules seems simple, I haven't spotted an explanation of the semantics and how that maps onto USB hierarchical structures. Once upon a time I might have bothered to learn that, but the attraction of learning yet another scrotty little Domain Scripting Language and underlying structures doesn't appeal to me.

[nctnico]

Where it comes ACM interfaces, the best thing to do is make a udev rules which makes a symlink in /dev to a device entry you name yourself. So (for example) the text interface is on /dev/bp5-text and the binary on /dev/bp5-bin
What the rule is based on (USB interface) or a unique device feature depends on what you want and/or which unique features are available.

If you have multiple devices, you may want to add numbers but that is the next step.

[shabaz]

EDIT: Please ignore this message, it's not a solution (it won't work when additional ttyACM's from other devices are present).

I'm using Windows normally, but gave it a shot, this is currently working for me (with Ubuntu):

I plugged in the BP5, and typed (a wide screen is needed, otherwise it will truncate the grep'd result on the right side!):

Code: [Select]

udevadm info /dev/ttyACM0 | grep ttyACM1
I made a note of the line containing DEVPATH= and then typed:

Code: [Select]

udevadm info /dev/ttyACM1 | grep ttyACM1
For me, the two results were:
/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2/1-1.2:1.0/tty/ttyACM0
/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2/1-1.2:1.2/tty/ttyACM1

Then, I created (as root user) in folder /etc/udev/rules.d a file called 97-buspirate.rules:

Code: [Select]

# BP5 udev rules file
#

SUBSYSTEM=="tty", ENV{ID_VENDOR_ID}=="1209", ENV{ID_MODEL_ID}=="7332", MODE="0666", DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2/1-1.2:1.0/tty/ttyACM0", SYMLINK+="bp0"

SUBSYSTEM=="tty", ENV{ID_VENDOR_ID}=="1209", ENV{ID_MODEL_ID}=="7332", MODE="0666", DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2/1-1.2:1.2/tty/ttyACM1", SYMLINK+="bp1"

Then (still as root user) type:

Code: [Select]

/etc/init.d/udev restart
Then, un-plug and then re-insert the BP5, so that things take effect.

Since I don't know how to use minicom, I did (as root user)

apt install screen

Then, as a normal user, type:

screen /dev/bp0

The Bus Pirate text menu appears. To exit screen, press CTRL+A, then press \ then press y

I didn't see the VT100 colors, but I think that's a problem with my terminal settings, I was SSH'ing in to the Linux box from a Windows PC, using SecureCRT. Ordinarily I will use it with Windows, and in that case, MobaXterm displays the colors. SecureCRT doesn't for reasons I've not got to the bottom of, but at least there is the MobaXterm workaround.

EDIT: p.s. the LEDs are slowly growing on me! : ) Working in a dimly-lit room, it looks like something alien..

if you must do it full time specialize in one thing really well . know your subject better than the average viewer.
do you have a voice for radio or a face for television?  then welcome to the entertainment industry.
 if not, don't give up your day job IMO.
if like Me posting the odd yt video is just for the fun of it, not for profit hobby.

[tggzzz]

know your subject better than the average viewer.
do you have a voice for radio or a face for television?

Knowing the subject better than the average viewer doesn't seem like a difficult hurdle to jump.

I think I have a TV/radio face/voice. Besides, the evidence is that it isn't important.

This is not going to work. As soon as you plug a phone in or any other device that registers as an ttyACMx, the numbering will be off. You'll need to look for some kind of sub-device ID and use that for matching. So vendor id, model id and sub-device number should be used for the udev rule to make it universal. That way no matter which ttyACM the BP5 is assigned to, the symlinks will always work. You can also include the serialnumber (if the USB device has one) and have specific devices attach to specific symlinks.

That was my presumption as well.

I haven't seen any definition of the mapping between what tools tell me is on the usb bus, and what can be put in a filter. So what would be suitable filters, given

usb-devices output is

You can try to look up the ACM devices from the BP5 in sysfs and trace back to the device driver / bus instance they belong to. From there you might be able to spot a useful discriminator to seperate the text and binary interface.

Well, I have spent too much time trying and failing. Yes, I'm profoundly ignorant of USB and udev, and have absolutely no inclination to change that. Fundamentally this information should be supplied by the manufacturer. Since this is a new device, I will cut them some slack - and wait until a usable workaround is announced.

If it doesn't appear, then I'll point it out. I'll probably be one of many doing that.

I'll just use /dev/ttyACM0 and call it a day.

[shabaz]

I didn't think of additional ttyACMs, good point.. I can't find a way to do it either : (
I could only come up with this not-so-great workaround. I have tested by inserting another ttyACM device, and it seems to function OK (replace 'screen' with minicom etc), and save with 755 permissions or similar. I'm not very good with bash so I'm sure this could be improved a lot. It assumes that the lower ttyACM value out of the pair will be for the text console, this seems to repeatably be the case with my BP5. Currently it checks just for ttyACM0 to 9, it's really ugly:

Code: [Select]

#!/bin/bash

PORT="none"
for i in {0..9}
do
  if udevadm info /dev/ttyACM$i | grep -q 'Pirate'
  then
    echo "Pirate device found at /dev/ttyACM$i"
    PORT=/dev/ttyACM$i
    break
  fi
done

# execute screen on the port if it was found
if [ "$PORT" != "none" ]
then
  screen $PORT 115200
else
  echo "No Pirate device found"
fi

if you must do it full time specialize in one thing really well . know your subject better than the average viewer.
do you have a voice for radio or a face for television?  then welcome to the entertainment industry.  if not, don't give up your day job IMO.

As someone who's made > 200 technical videos as part of his job:  early on I made the very deliberate decision not to appear on camera, despite many, many, many people telling me that my audience needed to see my face in order to "engage" with me or to keep their attention.  I told them that if the content itself wasn't engaging or interesting on its own, seeing my face wasn't going to make it any better* ....   

https://www.youtube.com/playlist?list=PLKxVoO5jUTlvsVtDcqrVn0ybqBVlLj2z8

There are successful video creators who appear in person (Keysight's Daniel Bogdanoff or Johnnie Hancock, and of course Dave) and others whose face you rarely see (Alan, W2AEW).  So I think there is room for both types of videos: you have to choose what works best for you.

* For better or for worse, it is actually my voice in all of the videos.  I don't have the budget to hire a voice actor

[Sredni]

Nice presentations.
I agree, the face is not necessary if your content is good.

May I ask you what you use to record these videos?

[vk6zgo]

I imagine a Jerry Walker style intro section - and a clean-starched-shirted presenter 

I don't know Jerry Walker, but it wouldnt be a clean starched presenter.

As my daughter once said with a strong tone of incredulity, "I didn't know you had an iron!" . I pointed out that I had owned it longer than I had owned her.

I might even wear a 50yo T-shirt, but I could sell it for a surprisingly large amount of money. FFI, spelunk in the TEA thread

So this is just a "cunning plan" to sell a collectable  t-shirt?

[pdenisowski]

May I ask you what you use to record these videos?

Almost every video I do is "narrated / animated PowerPoint" which I record using Camtasia.  Quite frankly, I probably use < 5% of Camtasia's features:  the "editing" is just me cutting out the parts where I made mistakes.  I'm assuming that most other screen recording tools would also work.

I do occasionally make "live action" videos and edit those with Camtasia as well.

Not really; it is too fragile, and I could only just squeeze into it.

Eminently fleabayable, though.

There is a picture of it in this forum, but people have asked me not to post it again

[TERRA Operative]

My advice... lol

You need more light for the camera. Nope, even more.... Still more... Keep going.... Do your eyes hurt yet? Ok, add some more.

Also, get a good microphone. Good audio makes sub-par video quality look better, but crap audio will make the best video look crap. Ain't the human brain weird?


Now, turn on the camera and start talking, keep retaking the video until you get bored, you don't have to do it all in one take. Then chop 90% of the crap away in editing, add a SHORT intro logo if you prefer and upload. Oh, don't forget to up the colour saturation juussttt a little, especially if your lighting is crap.

The next one will be better, I promise.

You need at least two Bird wattmeters in cascade, plus a CB radio you can key up and say "Aaauuudddio!"whilst you watch them "Bird Watts".

Well, if you want to follow the lead of the two best Youtube channels in the world, you'll need an annoying Australian accent like me and Dave.

Dude, the magic of youtube is in the clickbate. Keep the same style and upload regularly. By the way, you nail it with the names, like ¨MyTimeIsMoreValuableThanYours¨ its simple hilarious.

What an excellent clip; well worth disinterring it

I've been a fan of the Peter Principle as long as I can remember.

My first two promotions were meaningless. My next promotion was also meaningless, but I argued unsuccessfully against it.

Apart from that I've been able to engineer situations where hierarchy was more or less irrelevant. In one particularly fun and good job, I had my formal boss formally working for me.

Another very useful principle: obtain your "drop dead money" https://www.urbandictionary.com/define.php?term=Drop%20dead%20money

[Sredni]

"...and so, we had this guy - terrific guy - who was a computer guru, and could do anything he wanted with computers, and we promoted him. We put him in charge of the sound effects in all our new videos. And that's where he showed all his incompetence..."

For sure having enough on the side to be able to think coldly about your current employment situation is a huge plus. The things we are able to do to keep our current situation, out of "fear", are sometimes very, very dumb in hindsight.

There is an interesting corollary to what he says about inappropriate promotions, that I've seen people from numerous organisations report, and its inappropriate lay offs. In a lay off many of the very best people saw it coming, and found a way out before the event. Doers tend to make enemies, so many of the most valuable people get laid off by people they have pissed off. There is a third interesting group, though. which is talked about less. They were relied on heavily by people all over the place, but didn't have a single role that in itself made them so valuable that they survived the lay off. Yet it was clear to most people that they were the most valuable in the organisation. Without them things go very badly down hill.

Yep I concur on all points. Same experience. That means that quite often, during lay offs, the idea that companies take advantage of this to get rid of the "dead weight" is a false one. I've seen people making "lists", and that was never pretty.

It is from a 43 year old novel (set in '63), so that's not surprising.

Besides, I'm nice - which will be surprising to a few people.

How can I start as a new YouTube video creator? Would you mind sharing some more information. Have a very good day!

Have something to say that is worth other people spending their lives watching. Avoid "me too" and "I'm here" content.
Have something that requires moving pictures; if not then write a blog.
Edit edit edit. Remove all "ums" and "ahs" and "talking heads". Speed up the boring bits.
