Just got my kit. I want to learn how to use the osilliscope before I pay more money for a better one. I want to get a fan like you are using instead of a more expensive one to pull away the smoke when I am soldering. I like the cheap fan idea . Thanks for the review.
Great video. Thanks, gonna get it. I wish it was rated at least 1MHz. But yet, for diagnosing switching power supplies and similiar projects is just fine.
As an ex professional bench soldering tech at a board assembly house I respectfully disagree. My old boss would have fired this kid on the spot! I'd be cursing a while reworking that board too. It is far easier just to do it right the first time.
How can i use this to check frequency of power coming from generator? My killowatt meter give me the number but i need to see the wave form to see how "dirty" it is
I came from todays video - followed the link to the pwm and saw the oscilloscope which I searched for on your channel and finally found it ... but that was a lot cheaper: price has gone up by 50% ... I guess result of too many too good reviews cause once the chinese smell a surge in sales the price goes up. But thanks a lot.
I need something to check if the display uses PWM technology, and so the screen will flicker. What I can buy that let me test if any display device I use use PWM?
This should work to see if the output is PWM, but you could also use a multimeter with frequency measurement since you don't really need to see what the waveform looks like, just if it has a switching frequency. Also, if you are able to connect the controller to a display for testing, you can use your phone camera at fast shutter speed (like 1/1000) to see if the display shows up having black stripes. That will tell you that the brightness control is PWM.
I paid the $5 extra for the built one... I think it was that amount... I'm not that cheap... Yes I am with the rest of the stuff I ordered I spent like $130 without including the stuff ice ordered so far. This hobby is going to bankrupt me😭
I'm all for building stuff but when 95% is already done and you can buy a fully built one for the same price what's the point? You can't say you built it and it doesn't save you any money.

Good to learn on.Also good for finding outside foil on caps. Glad you realize this is not a bench type scope and it's limited.
I love electrical engineering 😍

That's so cool! I like to buy dismounted things to assemble them :D
Is it necessary to download the software for this device or not, and does it work well???
It really looks awesome, dude. Really nice!
Thanks!

That's because you're or were a professional on this, I'm not. Cheers.
When diy, you can choose what components to use. I will mostly threw the stock resistors and caps and replaced them with better ones.
Why would you do that?
@@Osama-wj5gn the ones that come with it are cheap-feeling

does that have a power supply that needs to be plugged into the wall? batteries and portability would be nice for using it on the car
thank you sir! ill but this one.. btw your link doesn't work.
WOOOOOW We use it!

Can I use on a 120v 240v inverter ups. All I want is something cheap to see if this one I got is pure sine or square wave. There is no markings
my question is.. if applicble for led tv
signal? like spi flash ic? ...
seams like a good product for 20 $
0:14 Well, you can, just really slowly, and you'll have to graph it yourself.

Could this be used to see amplifier output clipping
Yes
Injust saw you can buy these built for cheaper than the kit that makes no sense
its not USD20 anymore, its price is now USD40 - 50
same DMM !
I guess you don't trust the resistors color code?
No, I prefer to double-check
@@Joyplanes Fair enough.

My god I have to build the unit I never what to buy a product to build
tfs
Beware, literally every one on eBay bangood etc is fake.
Is the link in description legit or another knockoff?
knockoff
@@rsattahip How do you know? The pictures in the comments have jye tech logo.
The link will only take you to the poroduct page at banggood . com
@@Joyplanes And that product is same as in you video?
