This tiny 2MHz Oscilloscope has everything it needs to be a real oscilloscope. Adjustable timebase, V/div setting, a lot of trigger and measurement options and freely draggable cursors.

Busted out laughing when I heard: "a nice solid state relay ... haven't heard that one clicking yet."
needs more voltage
Mo powa
This guy gets me
I actually know what it is, but didn't notice or realize the subtility there ahahah
great work on the highlighted-compenent circuit overview
+1 for "a bit of cushioning material" - that's me subscribed!
These kind of product reviews are quite valuable. Getting an opinion, while also seeing how the product operates, really takes the guess work out of a buying decision.
Thanks.
3:40 love the subtle humour
Jye just keeps upping their game. Looks nice for what it is.
i cant believe they fit all that into the ATMega64, didn't expect the little fella to refresh the screen so fast.
Good review of this little portable 'scope. Thanks for taking the time and trouble to prepare this video review.
Added bonus: I was pleasantly surprised to encounter a German with a sense of humor.
Cute humerous, and accurate.
It was valuable to me.
Would have cost $250 several years ago.
I have the DSO112A. It cost me $55. I had to wait three weeks to get it.
It is perfect, but a new scope would have cost me $250.
This is an outstanding review of this O'scope!
Your English is very good!
man you cracked me up jogging with a scope
Dave Jones did it before in some sort muddy Iron Man situation even ... if I remember correctly
LOL looks like a modern day boombox ghettoblaster... just like jogging in the 80's.
These tiny electronics like scopes and the TS80 soldering iron means I can have a fully electronics lab inside my van camper conversion.
The quick boot-up has me sold, just what I was looking for.
Tengo un DSO112A desde hace tiempo. Lo uso para depurar proyectos con Arduino (mucha señal digital y una que otra analógica). Pese a su pequeño tamaño y bajo precio, es un producto sólido (nada se ha desprendido, soltado o decolorado) que cumple con lo que ofrece. Estoy satisfecho con la compra.
I multitask when I watch your videos... I learn and laugh. Rare to find good comedy in tech, and the deadpan humor is an unsuspecting bonus. Sometimes I watch tech videos late at night before bed, and then I'm not ready for your humor, so I start to burst out laughing, waking my wife. Oops!
next: AvE
Electroboom (Mehdi Saghdar) is also a damn hilarious tech channel.
Wow! Jyetech scopes have sure come a long way since their first ones with too small monochrome passive matrix LCD's :D
Thanks, a great vid! I appreciate both the idea of the ECG amp, and the neat Bangood scope.
Love your videos, really glad I found your channel. I hope millions more discover it and subscribe as well.
I have one of these for Arduino related development. I'm happy with it. A "normal" osc is overkill for my needs and take too much room in my desk.
the 2nd ATmega chip might be for the USB interface.
"Solid State Relay...haven't heard that one clicking yet!" HaHa, I love the humour n these videos.
I think I've got one of the predecessors, the DSO15001K. It doesn't have an internal battery yet, but only a 9V input jack. Also no touch screen as far as I know (but already a color LCD, though it's a lot smaller). The problem is: It came as a kit, with the SMD elements pre-assembled, but all the discrete and through-hole stuff you have to solder yourself. And I have it sitting here since about half a year and still didn't get to it (the instructions also talk something about measuring and calibrating the thing during the assembly process). But at least it was only something around 20€, not 70€ as this one is. So that's the kind of money I'd like to spend on a scope (since I won't use it very often), this one is already too expensive for my taste (I bet I could add another 30€ and probably get something much better for 100€ or so). In case I ever manage to assemble this thing, I might even acquire the knowledge to properly test it ;)
just to go at it, that kit it pretty doeable.. just dont hold the soldering'iron to long on the traces, otherwise they will lift.
if you need some guidance there is multiple videos on YT taking yo step by step..
Great video. Thanks for the information and the laughs.
Nice review. I can see this being quite convenient due to the portability.
Thanks for making this video! I bought three of them :)
I have been testing various "mini" scopes and recently got one of these. I thought I might not like the small touch screen compared to the controls of the DSO211, DSO212, and DSO213 models (and they all have different physical controls). But I found the touch screen MUCH more intuitive to use compared to those other scopes where you are forever cursoring to select a menu and then cursoring more within the menu. I did not find it came anywhere close to the 2 MHz bandwidth claim. At 1 MHz a square looked just like a sine wave. And at 2 MHz a sine wave was presented at two different heights with alternating cycles. I would say this is more like 500 KHz usability, maybe less. The particular one I got had a problem where the 50mV and 5V vertical sensitivities were displaying, and showing measurement data, that was double what it should have been. I figure perhaps a wrong resistor value got loaded somewhere, but not sure how and affect only those two ranges. But I know the issue is there, can work around it, and for the low dollars involved, don't want to hassle with the vendor. Also, it came with no manual but you can easily find one online. This might be important because of the tiny hidden battery disconnect switch under a tiny slot on the top. I didn't know about that (who would?) and at first thought there was something wrong. Considering the cost, and if you have no scope at all, or really need a tiny portable one, this is a pretty good value. It's about as low cost as you can go without getting one of those DSO138 kits. Also, since the case is a little deeper than most of the other "mini" scopes, they seem to have a little larger battery and I tested battery life and it was about five hours. Quite good. Unlike the other mini scopes, I could not find a way to adjust display brightness.
About to order it but wanted to get someone's opinion that ones about this stuff way more than me. Made my decision easy. I'm just a hobby guy so it was between this and that cheap 30 dollar one you solder yourself. Which I had worked for 2 weeks then stopped. But paying 30 for that junk or 50 for this is a no brainer
Lol, didn't know German's had a sense of humor. Thanks for making my day...from USA
Nice ! I think im gonna buy this one.. I've been wanting a cheap oscilloscope that i can use to check for overshoot in psu's , and since i dont know much about electronics (just started this as a hobby) i dont wanna spend few hundred dollars on a proper oscilloscope cause i might damage it or something cause i dont know how to use them.. So this one looks like a nice option just to learn the basics on how to use these things :) Good review
You're a braver man than I'm more careful with my scope than with my life.
extra thumbs up for the volvo and manual gearbox. Why isn't the Rigol REPS'd out yet?
Marco says DSO112A Oscilloscope has everything it needs to be a real oscilloscope, then it is what I would buy. He does not actually do detailed test but I take his word at face value. Besides, I am not going to use it for high frequency work, that most people say cheap oscilloscopes fail to perform. Their so-called "reviews" are odd. All they test is voltage and frequencies.
They forgot that an oscilloscope is not meant to measure anything accurately. It is for 'seeing' what humans cannot see. What they need is a multimetre if they need to measure stuff.
They test for frequencies to know whether or not the maker lives up to their claim of 100 MHz, 120 MHz, 999999 THz. And they forgot that serious work requires serious tool. It is like putting the blame on a shovel for not doing an excavator's job! WTF!
How the heck merely testing voltages and frequencies reflect the usage of an oscilloscope?!?!?!?!?! What about real-world usages such as the ability to zooming tight into the very small and weak signals? How about features that are very useful, that an oscilloscope ought to possess?
DS212 seems to be the perfect one as it has two channels and lots of stuff as well. But it is a lot more expensive than DSO112A, and there are only two buttons cum wheels, these are the weakest links.
Wave2 (Same maker of DSO112A) is a two-channel oscilloscope and is inexpensive compared to DS212, but it sucks because it cannot overlay traces. Not helpful to have one top and the other bottom.
Ugh! Chinesium!
ATMega88 could be... display controller, touch controller, USB bitbang interface. 1-3 of those things, I'm pretty sure.
As a African without much money I think this will be my next bday present.
Would have thought they would have used a single ARM STM32 chip (with integrated DAC etc.), but the contents really surprised me...
"biasing the whole human to a low but stable voltage" made me chuckle.
The part about biasing the whole human to a low and stable voltage was funny but it seems no one else found it funny
1:30 Marco! You have an S60R? With the spaceball shifter?!
nice
Interesting all the cheap scopes test use 200-5kHz signals. No more. This one had problem with the 1kHz one.
Hi! Thank you for the review. Just one question, is it possible to show a trigger overlay? I am hoping to be able to compare a CH1 signal rise event with the external trigger event.
I'm adding .. "between painful or deadly" to my personal lexicon.
Love your videos even though I don't understand much of it.
thanks marco, another usefull vid
Like the others I came to watch a video on a scope, then subscribed for the comedy.
Thanks. i already have one. *Can you share to us the squematics that you use for the ecg??** Please. i love the simplified version of an already simple circuit :D
Works great for me with Arduino freeq testing..
Nice R Wave Dude !
Do you think it's possible to use this oscilloscope on brushless ESC and motor for RC car I want to measure the Ripple voltage so I could make a capacitor pack that can reduce the Ripple current
This guy really has some good dry humour :-)
what a nice review, thak you.
Man you have great content but i have one more question. Whats the original circuit of amplifire i dont want to look for specific resistors with high precision
So, this would be good for basic electronics use? I have pretty much budget everything right now (soldering/reflow/hotair station, multimeter) and I just need a decent budget oscope.
Thanks for your review! Any idea how much better can it be than the ds138 at the limit of its sensitivity? Since it is the weak point of these gadgets - I work in audio, milliamps and millivolts is what you usually need to see. Any info would be usefull about this, cheers :)
Nice build on the amp. Can we see the other side? And thanks for that review.
The other side is empty except for the flat flex going to the LCD
Marco Reps no no... the other side of the pcb. So we can see your soldering.
Very nice job that scope, sample rate a bit low for most work, spend some more to get a faster one.
Are you sure there is just an (ok, two) Atmega in the scope? Nothing hidden under the display?
What is suitable to be used as electrodes for the ECG?
Again a very cool video ;-)
Yep, nothing under the lcd. Maybe instead of just grinding off the IC designation they went one step further and put false information on there to confuse people, who knows ... I just used copper sticky tape, that stuff will also be a major player in the next 1 or 2 videos (:
SPFD5408A display can be controlled by ATMega, because it maintains screen buffer, can use 8-bit parallel bus. The IC is inside display enclosure.
You're German but have the humor of an Englishman...love it.
Atmega processor, so a 8 mhz signal limit? Kinda make it useless. Anything below 200 mhz is kind of waste
Is the bigger oscilloscope (the first one you were running with) from Banggood as well?
(You mentioned "it's another affordable oscilloscope from Banggood" while referring to the smaller one...)
I'm looking for a good n' cheap one but prefer the bench top size that is also good for mains..
They do have the RIGOL DS1054Z I think, but it isn't cheap
TIL: H264 is pretty horrible with jerkily moving asphalt.
I believe if you "upsample" your 1080p footage to 4k and upload it like that, RUclips allows for a higher bitrate that should prevent such artifacts, even though the actual footage is still only 1080p. It might be worth a try if it's bothering you, but rest assured: I didn't notice it when watching.
This is ultimately up to the camera encoder bitrate, later re-encodes can't automatically fix it, if this is the case. But you can evade RUclips downgrading for any footage by triggering the generation of high-quality versions of your video: (up)scale to 1440p, bitrate 16000, audio FAAC 384kHz. This single upload will make the 1080p version higher quality as well.
Congrats, you made it on hackaday.
Chip Guy Vids cool! But with one of these product videos? I thought I had better ones in store
Indeed you do have better ones. Maybe they just were triggered by "oscilloscope", who knows.
On the very threshold of humour chip guy.
When will you make a diy heart ?
Looks neat, but... 2 MHz, ouch. Can you recommend something around 10 MHz?
CRT an option for you?
A preferred option ;)
@@reps Returning to this to say that (while CRTs are great) there are (O)LED displays now and obviously this is preferred to get access to a usable scope. 2MHz was not usable in 1976, from which I have a mint Solartron CRT 2-channel oscilloscope that is a very heavy paperweight, useful for no electronics. My need is now 2-channel 50MHz with logging over USB to file, and I find nothing but these big, heavy, expensive, impractical boxes with bad screens and bad UIs that toot about resisting great voltages and currents I never, ever, have the need to measure. Where is the small, simple box the size of the display that does this? Without a doomed-from-the-start rechargeable battery inside so I have to pay again in 3 years. Why is everyone fighting over the niche market when so many could have use of such a box? Audio interfaces are ubiquitous, and all that's needed is some components to prevent idiots from blowing up their laptop and some live sampling software, and it could dispense with the box, dials, and built in screen, and fit in a very small pocket.
great video as always. May I ask where you work?
For a price of 3, you get a 4 channel 100mhz branded scope.. with all the knob, big screen, 4 professional probes and pc software. How exactly is this cheapscope toy good?
Link?
Ehr, more like, for the price of 5.7 of these.
70$ * 3 = 210$ + (import 22% tax & 15€ import fixed costs) = 275$. Got a Rigol DS1054Z for around 300€ at local supplier over a year ago.
Daryl Sargent you can go with "ohnoes" scope, aw I mean owon from eBay which is 150-210€ on eBay in Germany. Add some 18650 instead of the batterydummy (empty) battery case voila
I must indeed congratulate you on getting your 1054z a good 100€ cheaper than anybody else.
And Owon? What kind of fantasy land do prices below 270€ for a basic 2ch version come from?
Oh, crap...hmm, not sure I only need one probe connector :( I guess as they are pretty cheap, I could just get two :)
do a test on the dso shell i think is the best hoby osciloscope
hey we're scope buddies!
what is the screen size diagonally?
Next build an EEG amplifier! :D
Isn't running illegal unless the police are behind you?
I spit my damn beer out, this is funny af!
Towerdog what I like about his humour is that unlike AVE, it doesn’t get to a point where you stop laughing as much
Can you do a review of the DSO 150 also from banggood
With the JH, is it possible to update the firmware ?
ATMEGA 8 bit alone cannot sampling to 20Mhz , I think.
that's why these use an external ADC
v70r or v60r??
Awesome channel, great content, and very informative....I binge watch your channel when I can...but, can you say, "Yippy kayay mother f*cker? It'd be like an homage to actor Bruce Willis.
I want to hear him say, "Now I have a machinegun. Ho-ho-ho"
YES! YES! YES!
I'm sorry, i thought for a second the T-shirt read PNSHR (which i take to mean Penishure). I had to rewind to ascertain myself. Alas, this was not to be the case. On second thought, PNSHR would have more likely meant Punisher. I am now doubly disappointed and am also doubting my sanity.
I do happen to have a punisher shirt too :) (The one with the skull from the movie ...)
I must have been thinking of "Hyperscheisse - The Dimension Beyond" by Penishure. The video must be somewhere on RUclips. It's from pre-RUclips times pretty much, which explains some of the humour, like the parodies of ringtone ads on VIVA, gangster rap parody, etc.
I don't understand why manufacturers don't use screens such as the iPhone 4 screens. they are cheap (under 5$) and good quality dpi.
Probably battery life? Those things suck power like nothing else alive. The battery in this unit wouldn't run that display for very long
ehmm what makes you say that. Where you pull that info from?
Because these low DPI screens are even cheaper and easier to interface with. Higher DPI screens require more bandwidth and might require more expensive interfaces as well, especially mobile phone screens.
A couple reasons:
1. Viewing angles. Generally these cheap screens will be TN panels as opposed to IPS panels. As you turn them off axis, they invert the colors.
2. Touch sensitivity. These cheap LCDs use a resistive as opposed to a capacitive touch screen, which is why they aren't as accurate or sensitive as regular device screens.
NE555 iphone and other smartphone displays are beasts. they require access to the mipi alliance video standart and a dedicated coprocessor of some sort for interfaceing. that greatly increases development cost, whereas this cheap lcd can be interfaced with next to no effort. Apart from that i dont see any reason why you couldn't use "cheap" smartphone displays (they are actually pretty expensive) :)
The GUI reminds me of "ImGUI" by ocornut
"simplified version of an already simple circuit" even that is too complicated for me and i dont understand anything lmao

First I realize you are German yeah we can't hide our "akzent" but then I realize you have the same shirt then me, under the black T-Shirt the blue and yellow one, damit. Warum schreibe ich eigentlich einem deutschen in Englisch?
Also a complete lack of deep memory and fft functions
5:01 penisoidal wave
Lol I like it
This is why you should not give an oscilloscope to Arnold Schwarzenegger.

they now use your video as advertisement, XD
whats that electric screwdriver thing? and is the touchscreen resistive or capacitive?
Touchscreens that can be operated with a plastic pen are always resistive.
well there are pens that can be used with capacitive screens and i wasn't sure whch kind that pen was.
Ha!! His 'Electric-Screwdriver' thing, is a 'De-Solderer'. Heat + suction-pump.
Never ever buy it !!! LOL
