DS212: Open source 2-ch oscilloscope and signal generator

Buy one: www.banggood.com/custlink/3GG...
Or a much better one: www.banggood.com/custlink/vDG...
Or give money to me: / marcoreps
After seeing their 'side projects' TS100 soldering iron and ES120 screwdriver, I finally got a pocket scope from miniware aka minidso.com. Is it as good as my previous experiences with their products suggest? I'll put it through its paces and take it apart to find out. I'll also try to modify its open source firmware to add another waveform option to signal generator.

iconic listening to a faceless German voice extolling the joy of examining fine engineering.

[@jonny393]

Scope called DS212...so he ofc has to play Azalea Banks "212" in background in the beginning xD gut gemacht :D

[@reps]

Aha, I thought noone would notice :)

[@agumonkey]

I knew it was suspicious.

[@35mmMovieTrailersScans]

You're a menace to my financial stability! 3 times that I've seen a video of yours and immediately rushed to buy the subject of it. Great channel, don't stop.

[@amayachannel4517]

Same

[@DoctorCalabria]

Same here. Just bought the DT71 tweezers to complete the DSO and Screwdriver troika.

[@tobystewart4403]

Marco, if you were to make a series of tutorials regarding the proper use of the Oscilloscope, you would significantly improve the condition of mankind. Bis bald.

[@DazzaDirect]

hint HINT, ;-] please ;-]

[@transkryption]

tutorials on anything really... how to clean a room... how to avoid malnutrition at university... all güt !

[@kyatto7708]

I betcha guys enjoy his calming voice

[@aneeshprasobhan]

gay

[@andrewwilson8317]

Yes!, getting myself one of these. Oscilloscopes such a major part of my fault finding,testing and diagnosis work.

[@alliefdxproductionservices5856]

I would love to see this company do a benchtop scope with the same design philosophy. I mainly work with audio stuff, and it'd probably be so much more useful than a lot of the cheaper bench scopes that end up on a lot of audio workbenches.

[@marcus_w0]

OK.. gekauft. I love the way you did this "mini-review"

[@ernestboston7707]

That looks cool, I think I can now justify getting my first oscilly-scope.

[@AlphaBobFloridaOverlord]

Marco - you are a very bright man! Thanks you for sharing your insights. My DS212 is on its way, I'm very excited. Any additional tutorial information for people starting from zero would be appreciated.

[@manickn6819]

Nice work. I don't need one but its good to know whats out there and how it performs. Thanks for adding some good info to the community.

[@gregzambo6693]

THANKYOU ! Your channel is excellent, and this is the best. I just bought one.

[@johnleach7879]

Even allowing for Toby's comment, below. I'M IN LOVE!

[@leozendo3500]

Love your video content as always. Your channel would probably gain much more subscribers soon.

[@ryanmason9141]

Volvo!! I just ordered this scope. Thanks for the review

[@oturgator]

Curve tracing would be super helpful.... Thanks for the video!

[@mborowski2010]

Thanks for putting this out there. I'm buying a real desktop 4-ch oscilloscope but I was also wondering if there was a open source project yet. I will buy this for that reason to modify and build from it. And it would be great to take to work and find problems in the equipment at my print shop. So many times one of these would have saved me from hours of trying to find the problem.

[@oliver1224]

Very good video.. I've got this pocket scope.. had it for a while.. still very happy with it.

[@briancrane7634]

Marco your videos have noticeably improved the human happiness factor in Texas...

[@WaltonPete]

I've seen a few of these around but it's good to get an honest opinion - looks like a neat bit of kit, handy for when a full-sized scope isn't practical.

[@juancarloslincangogallegos3978]

Pete Allum a (

[@kentvandervelden]

Open source, cheap, and looks great? Wow!

[@tonysfun]

Another great video again! Thank you for doing this for the benefit of everyone by sharing what you know! I hope you will continue and I'll wish you Happy New Year 2018 !

[@modfabcom-au9909]

I really enjoyed that Marco and of course nowwww I WANT ONE!!!!!

[@spencermoon1371]

YOU ARE THE MAN! NICE ONE MARCO

[@BrunoPOWEEER]

Yeah I have 3 scopes here but I always wondered about this little one, portable, descent quality, open source, accessories.. I may give it a shot too, thanks for the info mate!!! Your channel is AWESOME!!! =]

[@cannaroe1213]

Did you try it and was it any good? I'm shopping for my first scope :-/

[@greenthizzle4]

canna roe yeah I'm curious too

[@matthiasmartin1975]

I love the look of the GUI elements - reminds me of the ancient X Athena Widgets (Xaw).

[@RodrigoVzq]

I would buy asap. I love this chanel. Cheers from Argentina 🇦🇷

[@mononix5224]

Loved the video, keep up the great work ♥

[@kimfucku8074]

Looks very good and the price is very interesting!

[@d3xdrive]

Now these guys need to focus on making either an awesome open-source hot air gun, or an open-source desoldering tool. :o

[@_who_cares_1123]

Hates a tip: If you want to move the cursors for a loger distance just press the s wheel and spin it left/right to scroll faster

[@heyarno]

This reminds me a lot on my DSO203 that I bought many Years ago.

[@sicks6six]

surfing just took on a whole new meaning

[@AliasUndercover]

I really wish I had a use for a scope now.

[@alexm7056]

This is cheaper one and huge step back from 5 -year older DS203! DS203 is using slightly older generation of ARM CPU (Cortex M3) but it gets help from separate Latice FPGA to handle acquisition from external 40MHz ADC (schematic is here: www.minidso.com/forum.php?mod=attachment&aid=MjM0MHxhNmQzODAxZHwxNTI0ODU2MTYyfDB8NjY2). While, a shown, this DS212 has a single STM32F303 doing it all. Cortex M4 with FPU has a couple 5MHz ADC units built in. But continuously running ADC peripheral at this speed in STM32 is basically useless, DMA gets so loaded that you barely can do anything else. So what you do in this case - is loop sequence of three steps: , , . Which, if done effectively, provides robust UX. But internal ADC is crap anyway I consider DS212 a very good demonstration of STM32F303 capabilities. Well done! Kudos to the development team demonstrating great expertise in STM32 (like they do in all of their other products). To be noted - the same controller have been used in many quad-copter flight controller boards as well, new designs however already using STM32F7 (what is like 4x faster than F3)

[@1959Berre]

I just bought a vintage analogue scope in perfect condition. But this one is one my list. 1MHz range is rather limited.

[@Crazy--Clown]

Amazing!!! Last time I used one of these it was called a CRO 😊😊

[@elgringoec]

Yep, that's all I've got, still.

[@arthurdent8091]

A great video. Very informative. I would have liked to hear the price at the time of production, but this is a minor matter. Overall excellent.

[@mohammedlokhandwala8294]

Hi, How does the output compare with traditional oscilloscope in terms of accuracy?

[@aimeiz7637]

Grat video & product. I have just placed an order on Ebay.

[@RobWhittlestone]

Great video! I don't need one but would love one anyway!

[@vgamesx1]

5:48 It can play snake? SOLD!

[@andrewdronsson9028]

Yesss! A scope without snake cannot be professional one. :-)))

[@nicknicolosi1]

lmao, right? Old Nokia times hahaha

[@stonecold7945]

Hi and nice R & S scope

[@christopherbishop4339]

Two videos in a week? It must be Christmas!

[@drdfx159]

Thanks for the review. I've seen your review of the DSO112a as well. Which one do you hink is better? Can one use both the signal generator and the scope functionality on this one simoultaneously? Thanks!

[@notofinterest]

tnx for review. i'll order it.

[@sendark001]

You’re so funny and clever. Hats off

[@PetterBruland]

I do not need one, but you made me want it really bad :-)

[@AJB2K3]

How does it compare with the DS102 and DSO Quad scopes? ouu uses the 303 instead of the 103

[@davidillyes8510]

Blesse you! :D

[@schnibie1991]

Great Review i always thought about to buy one but I chose to buy the rigol ds1054z instead.

[@GONZOFAM7]

Perfect for my synth.

[@steventaylor6294]

Great voice over.

[@Anvilshock]

Ooooh, nice filter!

[@JohnoScott]

Great review (bless you)

[@josephthibeault4843]

Nice little unit

[@bloguetronica]

Not bad for the price! The function generator is not very well characterized in the specs, but I guess it works at 20MSa/s and has no reconstruction filter. The 10MHz maximum in square wave mode and the 20KHz maximum in sine wave mode are giveaways.

[@avejst]

Thanks for showing 👍😀

[@VEC7ORlt]

All it needs is protocol decoding and I'm sold, but I'll buy it anyway as having a cheap scope to lug around in your toolbox is a must, for checking stuff like I2C, etc. I also wonder should I get this or DSO Nano 4ch.

[@AJB2K3]

What gen DSO Quad Nano? I have the first gen which suffered from noise. (Still present after the firmware upgrades.

[@aterack833]

Next one needs to allow wave generation from SD card using a certain type of audio file (some rate or something that lets it actually generate it)

[@MCsCreations]

Wow... Really nice!

[@daskasspatzle2396]

G'sundheit ;-) Geniales Gerät, gerne mehr davon :-)

[@ozzymandius666]

There seems to be a model DS213 out now, 15Mhz Bandwidth.

[@mariusjansen3528]

Great Video!

[@GlennHamblin]

Very cool. Thanks!

[@elgringoec]

Interesting find! Makes me think somebody could develop an oscilloscope which could use a smartphone as the display via Bluetooth or Wi-Fi.

[@EverythingYouDoIsABalloon]

Ez Marco, thanks for your informative review. Would it be possible to tell me whether any of these mini scopes have 'Roll Mode' for the display, apart from the DSO112A model please? I need a cheap little scope to view CV modulation sources in my modular system and some of the cycle times will be over a minute or even longer - Is this what you need this feature for? It seems odd that the 112A has this feature and none of the other more expensive models appear to have it.

[@shrimpbynightbythomas8212]

Nice new toy!

[@RoboCNCnl]

Cool stuff

[@megavolt1978]

You the best!!! GOOOD )) More please about self modification this model ..... Please )) Thx )

[@pinkponyofprey1965]

There is nothing in this video I don't like So I hit thumb up and subscribed! :D

[@dimitris470]

Nice one. I will look it up, but does it have any digital filters?

[@Arek_R.]

You just made me buy this scope and soldering iron, was going to get their screw driver as well but it's out of stock xD

[@reps]

a little bird told me that there might be a successor of the screwdriver soon ...

[@Arek_R.]

Good, will wait. Have you tried running TS100 at higher voltages? Will it reduce lifetime of the tip/heater much?

[@gerdbaier9437]

does the probe have a x1-x10 divisor switch? and do the probes need to be calibrated?

[@claycoates5056]

thank you

[@krazyrican1v325]

what is the max AC voltage this thing can accept?

[@cesarjorgemurillobarientos1813]

Very good

[@kjamison5951]

Sweet!

[@omerk8403]

i like this company well

[@drojf]

First time I've seen IAR embedded workbench in a KZbin video...

[@daslolo]

Can it calculate the total harmonic distortion of a signal? And have you tried adding new functions such as real time logging to an external UDB HD?

[@nickhubbard3671]

5:29 Gesundheit! Thanks for the video!

[@fulontos]

Hey man, quick question. How did you compile the code you edited?

[@Ard-War]

Dang, no variable speed for the encoder? I wonder how long it'll last if it need *that* much rotation to move the cursor/offset :| Time to -hack- modify the sourcecode? :D

[@LoganDark4357]

Just use a dremel to spin the encoder :)

[@tanjiro3285]

My favvvv vido on ytb😁

[@devrim-oguz]

Change the Squar to Square while you are in there xD

[@reps]

If you catch those 2 frames after the code editor, you'll see that indeed I did :)

[@nslouma]

Yes, another one. Now have some sleep, Marco!

[@djruido1]

Awesome gadget

[@voytekfid7734]

5:28 Bless you :)

[@TheJellyfishdude]

man the stm32 is everywhere. even in my drone racing flight controllers

[@DirtyRobot]

Most of the innovation and push for better architecture has come from the quadcopter community. We needed to run more code faster for real time applications.

[@superdau]

They are really old actually. It's annyoing that Arduino picked the AVR atmega. The STM32 line is (and was for a long time) so much more capable for the same price. The hobby community definitely helped making it visible though.

[@jonathanglass]

Hi Marco. I have just received my DS212 but I can't find a way of making it trigger on pulse. It only seems to have rising and falling edge triggers. Do you have any suggestions how I might add this feature as it is incorporated in the DS203 predecessor. Regards Jonathan

[@user-xf3gw6fo2n]

Actually, this source of design is not so opened well: no schematic, Chinglish manual, just only source code... I feel the probe design seems to have some issues with the front-end circuit as well. I had do extensive research of these open-sourced oscilloscope, and try to match those marking appeared on Macro's video. Following is my findings, please correct me if any errors. Part Marking Pkg Description U1 HC4053 TSSOP16 => High-Speed CMOS Logic Analog Multiplexers and Demultiplexers U2 HC4053 TSSOP16 U3 8061 SOT23-5 => SGM8061 500MHz, Rail-to-Rail Output CMOS Operational Amplifier U4 8061 SOT23-5 U5 STM32F303 VCT6 => ARM Coretex-M4 CPU U6 25Q64FV VSOP-8 => 3V 64M-BIT Serial Flash Memory with Dual/Quad SPI & QPI U7 5239B MSOP8 => LED 3 or 4-channel constant current driver U8 SL6GH SOT23-6 => SGM3204 Unregulated 200mA Charge Pump Voltage Inverter U9 4VZM SOT23-5 => HM1134 300mA Low Dropout CMOS Voltage Regulators (3.0V output) U11 8061 SOT23-5 => SGM8061 500MHz, Rail-to-Rail Output CMOS Operational Amplifier U12 8061 SOT23-5 P.S. Wish somebody could try to reverse engineer the design and make it really opened! Regards, ttc

[@Pyrlixx]

And now it would be great if i could connect my PC/Tablet/Whatever to it and get the readings on a bigger display.

[@LoganDark4357]

Make a GitHub issue and it will probably happen

[@zanpekosak2383]

If they implement USB type C is should be perfectly feasable.

[@ScoopexUs]

What do you think about the NeverMindTheBrandName DSO328, and can you recommend me a DSO that will trigger to a synthesizer waveform and display the waveform full-screen (menus off)? I just want something to press a synthesizer key, tweak the synth, and see what I'm doing to the waveform. I know only (various brand names) 203, 212, 138 and 328 model numbers.

[@ScoopexUs]

Obviously I couldn't have

[@mouseminer2978]

Does this one has xy mode so it can be used as curve tracer? Thanks

[@avejst]

Thanks for sharing :-)

[@OB1canblowme]

Not that experienced with oscilloscopes, so, is it possible with the right attachments to measure up to Cat III voltages and do non invasive current measurements? Looking to buy, as a Christmas gift, a replacement for my fathers Fluke current clamp that borrowed and lost in my teens. So i thought that instead of a Fluke current clamp that only can do one thing I'd buy him a DS213 with the right attachments so he can use it when he's troubleshooting fixed single or three phase installations as well as when he is working on cars, snowmobiles or computers.

[@swandonovan]

is the ds211 the same thing but without the gimmicky encoder wheels?

[@pirateman1966]

Well, that was refreshing...

[@Motorman2112]

2:06 reminds me of my Rigol.

[@Bianchi77]

Nice video, thanks :)
