    This channel is Linux of the diag world. Open source and innovative. I might be wrong, but I think you are the first one to sync mechanical sound with voltage signals (except knock sensor application).

      It is an open source channel, that's for sure:)

      Mekenzi M I’m guessing u probably don’t use Apple products. I’m learning they r very restrictive. My Nexus 6-P allowed me to plug in a thumb drive and download videos onto it. iPad says too much power u can’t do it. I’m also thinking his scopes would work better with Android stuff. Thank u!!

    I have been binging on your videos. I love them so much I have built a few of your gadgets with some success. I completed the stethoscope and indeed it sniffed out some noise from the injection phase. Amazing stuff. Keep up the great work!!

    Thank u for this excellent channel. And to have Martin Loren comment, that is really neat. I’m not real tech savvy. How does my old Vantage Pro compare to the scopes u have made and modified. I like the idea of using your phone or iPad. Sorta like that little u scope from AES wave. Your scopes r two or more channels which make them much more versatile as u can sync other events. I watch and like every video u come out with. Also really enjoyed your dialog with Super Mario. Looking forward to the build.

      I hold 2 Inter-Provincial Trade Tickets and I have never owned a Snap-On screwdriver. Not a fan!
      U-SCOPE is nice and portable and useful. But not comparable to what has been developed by Martin in HScope using ANDROID and squeezing capabilities out of many brands of budget oscilloscopes.

      Martin Loren has a new development HS-ACC which is a simple to build ESP32 and ADXL345 project... more channels so will open door to 2 plane dynamic balancing. I'm building a 3D printable balancing machine based on his work now!

    UnReal, this is Awesome! All I could think of was the fuel injector current ramp, lining up perfectly with the open close event of the injector! Guess I'm building this too!
    The pulse sensor I built works flawlessly!
    These are all AWESOME gadgets your are creating Sir!
    Thank you!

    Awesome channel I’ve been enjoying your gadget videos a lot! I couldn’t help but laugh that you created this tool and THEN try to find a use for it. That’s proper tinkering!
    The thought of using it on a water pump synced to the pulley has me intrigued. Stick a magnet on the pulley and use an old crank sensor to pick up the signal perhaps? Could possibly be used to confirm bad impeller vanes? Might need a known good to compare though as typically all the vanes are worn and not just one or two

      Watch the FFT, the dynamic balancing videos and table saw vibration analysis. Very much related to your water pump.

      there was some housekeeping where some videos were deleted (I explain why in GADGETS#188)
      however, the stethoscope build was not one of the deleted ones...you will find it in GADGETS#52

    i'm just now starting to use the FFT option on my hantek ,from what i gather so far and may be wrong . but it can graph different frequencies ,so if using the FFT math function it might steer you to an appox. freq to test at at. i've got to build one of those to see if i can find wheel bearing noise,or any bearing .with that tool a side by side measurement might tell the defective one,good work on making a useful tool,thanks for the info

    • @theGADGETSplaylist
      @theGADGETSplaylist  5 лет назад +1

      +henry robinson - yes, you're on to something with the FFT function.
      Being able to tell if it's wheel bearing noise, electrical noise, unbalance is what looking for sync companion gadgets for this stethoscope is all about. Success is not guaranteed but we're going to work on it here.
      These are tricky waveforms to capture partly because the injector induction spike is peaking at 80v and the stethoscope channel might be 200 mV

    • @theGADGETSplaylist
      @theGADGETSplaylist  5 лет назад +1

      +henry robinson - Martin has also encouraged me to make more use of FFT in my videos. I've shied away due to concerns of "spooking" my viewers. Similar to sticking with THT soldering and not scaring anyone with SMD work.
      Both are about to change.
      While I'm waiting on components for "companion gadgets" for the stethoscope, we'll explore FFT (which doesn't require parts) more deeply as a tool to extract more information out of the stethoscope.

    Sir, i am planning to buy the loto osc482 model, but i am worry how much voltage the devise will support. Will it be possible to use two attenuators hantek ht201 20:1 in series to test injector and primary voltages around 100 and 400 volts respectively?. thanks a lot.

    • @theGADGETSplaylist
      @theGADGETSplaylist  5 лет назад +2

      +antonio zanabria - good choice!
      Here's a link to the OSC482 manual that I host on my Google Drive if you want an early start:
      drive.google.com/open?id=1cuRcobSXWS9pn0igemzsuK9zE6DrmeC1
      It is a +/-5v oscilloscope and all scopes in that input range with 20:1 handle injector spikes which tend to be shy of 100v
      The OSC482 has +/-50v over protection so with a 20:1 that's 1000v. The scope will overscale but won't damage.
      Never tried 2x HT201 in series. Perhaps I could design and build a 80:1 attenuator video. I'll think about it but I'm not that big a fan of primary work anyways.
      The best detail is obtained through the secondary and I trust you've watched all the COP PROBE and related videos on here...

    • @theGADGETSplaylist
      @theGADGETSplaylist  5 лет назад +2

      +antonio zanabris - As it turns out, this is a question also asked of Martin, so I pursued it further this morning.
      There is NO issue with simply using the HANTEK 20:1 attenuator even with scopes that have +/-5v input.
      The primary induction spikes above 35v are only occasional, do not hinder the capture and pose no threat to the scope.
      Hope this alleviates your concerns, Antonio:)

      I recommend buying just plain OSC482. Then, if you want to use it ANDROID, you purchase HScope licence on Google Play Store. And I recommend you later also get the AUTOMOTIVE MODULE licence within HScope. Each licence about $10 or so...

    'Listening' to the mechanical modules and extract a typical waveform from them, means actually to be able to check if inside things are moving and moving correctly before any other 'invasive' method?

    • @theGADGETSplaylist
      @theGADGETSplaylist  5 лет назад +2

      +Martin R&D - In the case of the fuel injector, it allowed us to confirm the pintle has moved when commanded. It's early days, but I also think this holds the promise of "signatures" where not only did it move, but did it move well...
