    The thing really doesnt beep enough! Why not add a even louder speaker and make it beep randomly when no button is pressed?

    I was hoping he was going to start the teardown earlier, if for no other reason than removing the speaker.

      Yandy it's not a speaker 😉

    There does appear to be a protection PCB in the battery pack.

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    I noticed that - not sure - could have been that the MCU is doing more in different modes, or maybe using internal RC osc.

    The indicator to the right of the frequency indicator appears to be the USB/data transfer indictor

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    Already mostly recorded - just waiting for time to do some high-speed demos to go with it.

    I think the OLED display might be an off-the-shelf part. The connection ribbon is slightly different but the display looks the same as the one on the 360 Lizard Xbox drive flash tool, right down to the amber-top-with-the-rest-blue colour scheme.

  • @tesla500

    I see what appears to be a Kodak motioncorder high speed camera control unit in the background, I'd be interested in seeing a teardown of that!

  • @BarriosGroupie
    @BarriosGroupie 10 ปีที่แล้ว

    Spot on review.
    I get the feeling that the design engineers created the spec over time, rather than leaving it to marketing who should know what field engineers want.

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    I doubt anyone makes converters less than 8 bits these days.

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    Yep - will defintely do that.

  • @TheSpatialTheory
    @TheSpatialTheory 10 ปีที่แล้ว +8

    That looks like the same OLED display used on the SanDisk Sansa Clip series of mini MP3 players.

    • @kyoudaiken
      @kyoudaiken 10 ปีที่แล้ว +2

      This OLED is EVERYWHERE...

    • @TheSpatialTheory
      @TheSpatialTheory 10 ปีที่แล้ว

      interesting, know any other applications?

    • @kyoudaiken
      @kyoudaiken 10 ปีที่แล้ว +2

      A pulse counter for your finger (china, too), MP3 players, cheap watches, etc.

    • @TheSpatialTheory
      @TheSpatialTheory 10 ปีที่แล้ว

      Neat! Thanks!

    • @drkastenbrot

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    Like I said it is NOT a substitute for a real scope, it's for situations where you need something smaller & more portable, like in-the-field testing & faultfinding.

  • @ubuntututorials
    @ubuntututorials 12 ปีที่แล้ว

    It makes me wonder why they used 8-bit converters when that thing has maybe 32 pixel resolution?

  • @t242p
    @t242p 12 ปีที่แล้ว

    The beep drops in frequency from the beginning of the video to the end. have I missed something or is this thing simply not stable?

  • @NickMoore
    @NickMoore 12 ปีที่แล้ว

    I have a hangover and I'm watching this with the volume way down. Another awesome video though!

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    Soft cores aren't always good value, as they use relatively expensive FPGA fabric compared to the optimised, dedicated silicon of a seperate MCU. This is why most FPGA vendors are now putting hard ARM cores on their chips.
    As to using two ATMegas, that's just plain bizarre!

  • @zloben9000
    @zloben9000 12 ปีที่แล้ว

    This product is meant to be used with a LAPTOP for the display and additional features.
    The screen is for demo only.

    • @AureliusR
      @AureliusR 5 ปีที่แล้ว

      That's... entirely useless then. Why not get an actual USB oscilloscope?

  • @Zagroseckt
    @Zagroseckt 12 ปีที่แล้ว

    i have a mouse with an oled screen like that on it.. (majorly burnd in at this point.)
    but i did notice theres 2 micro controlers in the thing. 1 runs the gaming mouse functions and the other simply runs the screen i wonder if there doing that here.

  • @coondogtheman
    @coondogtheman 12 ปีที่แล้ว

    Excellent review mike, You should try to get the OLED display to display things sort of like you did with the outdoor LED screen. And I've seen these OLED screens in buttons on video slot machines and one of my MP4 players has one.

  • @gvvq-pi5ml
    @gvvq-pi5ml 10 ปีที่แล้ว

    Hi Mike have they updated the software yet? I wonder if a DSO Nano Pocket scope is any better, I have one of those, there pretty good for what they are, more for hobbyist..the trigger line I think has to be in the area of the sine wave to stabilize it..ok interesting video from Fred Nr Chelmsford Ex uk

  • @megabytephreak
    @megabytephreak 12 ปีที่แล้ว

    The HWD9288 ADCs are a clone of the AD9288. If you look at the datasheets, all the diagrams (including the performance graphs) are copied out of the Analog Devices version. Wonder how well the ADC performance specs hold up.

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    I will probably hack a proper power switch into this and remove the beeper to make it more useable & keep it.

  • @bytmeh
    @bytmeh 12 ปีที่แล้ว

    Hmm that was not a very nice comment.... He clearly demonstrates an excellent summary of the product and I really value this review. I don't own a scope, but could use one for basic testing - and this has 100% helped me with my decision. Like he said "It's NOT a substitute for a real scope" ;)

  • @TedRobotBuilder
    @TedRobotBuilder 12 ปีที่แล้ว

    Sounds like it would be good to wait for the next version

  • @mikeselectricstuff
    @mikeselectricstuff  12 ปีที่แล้ว

    Yes - looks like it from what can be made out from the Chinese manual

  • @hairypaulmm7wab195
    @hairypaulmm7wab195 7 ปีที่แล้ว +3

    Whatever happened to using a proper battery isolation switch so there is ZERO power draw when the unit is OFF.. very poor design with super annoying beep. They can keep it..

  • @da959
    @da959 11 ปีที่แล้ว +1

    What a cool idea to put a scope in a probe case like that. It's to bad it doesn't work so well. Heck,I'd buy one if it actually worked..

  • @feenixb1o7
    @feenixb1o7 12 ปีที่แล้ว

    What do you do with all your parts? Are they for sale?

  • @mikewhite9178
    @mikewhite9178 12 ปีที่แล้ว

    That writing at the top of the screen really does look like OSCILLOCRAP!!

  • @francistheodorecatte
    @francistheodorecatte 12 ปีที่แล้ว

    only thing this has over old 10MHz analogue 'scopes is the portability. mine is 35lbs of CRT and steel.

  • @IanScottJohnston
    @IanScottJohnston 12 ปีที่แล้ว

    Good review Mike. I think if I had bought this scope I'd have had it in bits already and fitted a quick toggle sw in series with the battery. BEEP BEEP! Yup, beggars belief!

  • @truhlikfredy
    @truhlikfredy 12 ปีที่แล้ว

    When I saw the crapy triger modes, then I saw how long the video is and just wondered how you can stay so calm for so long with that piece of .....
    Suspiciously light chargers, when I opened such things then I got absolutely afraid to plug such things into mains ever again.

  • @ISmellBurning
    @ISmellBurning 11 ปีที่แล้ว

    Excellent mike, as usual.
    Hey, what other interesting sites are you hunting for gear from? >;-)

  • @RandyLott
    @RandyLott 12 ปีที่แล้ว

    It looks good from the outside but that's the only good thing. That beep is absolutely dreadful. Thanks for taking the time and sharing your opinions.

  • @gavincurtis
    @gavincurtis 11 ปีที่แล้ว +3

    They need to start including blood pressure meds and Zen music CD with each pocket oscilloscope sent to Mike for review. Poor guy.
    You want to see lazy programming? Pull code from Volvo modules. Compiled piles of crap. Don't even get me started on Audi firmware.

  • @szabolcsmate5254

    Holding a button down draws 120mA+. Well done. (slow clap)

  • @MrGerbilBrain
    @MrGerbilBrain 12 ปีที่แล้ว

    You forgot to teardown the charger! :(

  • @MrDubje
    @MrDubje 12 ปีที่แล้ว

    It's a nice concept, but the details aren't thought through... nice review, and nice setup behind you, whatever it is with the four monitors.

  • @kevtris
    @kevtris 12 ปีที่แล้ว

    that very yellow+blue OLED display is all over ebay. it's stupidly cheap, only a few dollars. the catch is there's no power supply on it so you have to provide your own (and it had that tab connection).
    The FPGA is amusing. The entire scope could've easily been handled IN the FPGA itself using soft cores and stuff. The code could easily have fit in blockRAM.

  • @gamccoy
    @gamccoy 12 ปีที่แล้ว

    I loved the tear down and the frank opinions. I've gotta say, I'm surprised you even bought such junk as that. If one needs a scope, one buys a proper scope.

  • @f16madlion
    @f16madlion 12 ปีที่แล้ว

    My digital camera by sony drains its battery over a few days, that camera cost over 180 quid the amount of times I wanted to take a photo and its been flat. Its such a crippling completely unnecessary design flaw. I do think you should pop that speaker though ;)

  • @AintBigAintClever
    @AintBigAintClever 12 ปีที่แล้ว

    Plenty of room for a proper on-off slide switch inside, if you remove that buzzer :)

  • @masterfoxxhun
    @masterfoxxhun 12 ปีที่แล้ว

    They are using the most common, and cheapest OLED display that can be found on ebay... I wonder what is in it's power supply/charger :D

  • @donpalmera
    @donpalmera 12 ปีที่แล้ว

    I wouldn't wait for a firmware update... I have a feeling they knock these things up from the parts they can find or recycle, sell them as quick as they can and move on to the next half working product. I don't know how they manage it but they seem to cover everything in foul smelling flux.. even if you order just components :/

  • @williefleete

  • @ForViewingOnly
    @ForViewingOnly 12 ปีที่แล้ว

    Excellent teardown Mike. What a shame the pen scope is such a P.O.S.! Remove the beeper and add an on/off switch in the battery wire and it'll be 25% less of a P.O.S. :-)

    Well considering that horrible QDSO thing Mike reviewed was made out of a repurposed MP3 player, it makes sense.

  • @ndyag100
    @ndyag100 12 ปีที่แล้ว

    its got that creeky plastic feel by the sound of it, i,ve got an old ozifox probe scope, and the specs are lower, at least its got a sold feel to it.
    I could do a tear down on the oszifox probe scope, any one interested?

  • @TheDragothica
    @TheDragothica 12 ปีที่แล้ว

    @1:26 i was thinking, i got a million mini-jacks at an angle, solder alligator clips at the other end = problem solved. But the beeping... it not only looks like, but sounds like a Wii controller.

    I couldn't agree with you more about the TOTALLY STUPID "standby" power consumption of some battery powered devices .I had a camera once that did exacllty the same thing ,drained the batteries when "off" . you could always fit one of those small on/off slide switches on the back I suppose , but you really shouldn't have to ,what a totally stupid design .!!!

    Thanks for the review, I've been looking for a little scope (and cheap) and from watching this I would have thrown it across the room a few times :) Maybe the Chinese are laughing at us and the CD contains the "real" Chinese software updates that make it work flawlessly in Chinese ;) A case of get what you pay for again :(

    lol, even my 10Mhz analogue scope is more useful than that, and it doesnt f**king BEEP. that off state current consumption is ridiculous, as dave jones would say, "you could fly to the moon on that" even my clunky binary watch only draws around 3mA with the LEDs off.

    Windows user complaining about UI, interesting. It's utterly ugly on the outside, so frankly I wouldn't expect them to put much thought to anything in it. If someone doesn't do a decent job on outside and inside design everything else is going to be shit too.

    Software for chinese products is a load of crap.
    Baofeng UV5R ..neat transciever for its price. software ? Useless. ( gladly we do have alternatives like chirp).
    My E-Bike BLDC controller ? Works fine. Software ? Crashes and crashes and crashes, so glad that setting is done "once" in a lifetime of that controller.
    Chinese LED wall software ? What a load of crap and easter eggs. Yes you could buy BARCO LED wall but everybody will laugh at your prices.
