Another great video! A wonderful explanation of what the code is doing, instead of just the syntax for a line of code. I learned soooo much. Thank you!
Excellent brother, finally someone who actually explains the limitations (especially bandwidth limitations) of an Arduino-based oscilloscope. I was trying to answer this on my own, and I had the same approach, I estimated a bandwidth not greater than 10KHz. Is nice to see people out there seeing the same budget limitations, and I kinda love having them because it lets me earn knowledge by baby steps and not just trusting my sources. Greetings from Colombia
It's amazing learning through youtube and you find videos where I'm not trying to actually build and oscilloscope just trying to understand how to interpret a waveform on audrino and the serial thing is a huge bonus. I also learn that since I'm measuring ac voltage, 480hz is plenty
Can you do it again using an STM 32 and a small display like they use in the DSO138? The reason I ask is because I want to use something like the DSO138 in application specific projects, where it would be a no brainer use. A rotary or toggle switch would set both horizontal frequency, vertical position and sensitivity, With only a few possible choices depending on what was being tested. I can do all the analog stuff myself, and know how to generate interrupts and run subroutines on switch closures to program the vertical and horizontal channels but I wouldn't know where to stuff the digital data into, or even access, the memory of the DSO138 to force program the horiz sweep or vertical offset and sensitivity.
I ended up with a Keysight DSOX1102G which seems to be getting the job done but I'm not really too terribly happy with it. I'll keep this in mind if I end up ever buying another.
Supercool! All your videos actually! D'you have the code for the windows app?! I'm very interested as to both it's functionality, as I've programmed a lot of MCU's but no actual windows software...
Hello! I don't know if you will answer but what if my project is about speech recognition and I used another app for it. Then I connected the app to the arduino. Can this oscilloscope measures the output?
This is awesome! I have got all the tools I need to do this as well, but one question: Can you tell me the name of the programm that you used to plot the graph? Thank you very much, have a good day :)
This is great info and facts on adc bla bla, but your audio microphone limiter (compressor) Attack setting needs a faster setting to cancel out those annoying fluctuations in sound.
It should run on any Arduino since I used only basic functions, but I can't guarantee it since I can't test it myself on other models. As to a Pi, I would assume they have similar functions that you could just use instead: Basic serial should be ubiquitous. The project release is in the description of the video "Homemade Arduino Oscilloscope - Open Source Release" on my channel.
@@simplyput2796 Thanks, I found your link on that other video on your channel. Based on that video, and I'm doing some guessing here, it looks like the Unity Game engine is a framework / library (possible c#) in the Visual Studio environment. VS does not run on any Linux, VScode (a separate Mediocre Soft product) is available as .deb, .rpm and as a tarball for Linux distributions. On first glance the Linux packages are binaries for amd and x86 platforms so it looks like my Rpi hopes are dashed as they are an arm platform.
It's limited by the processing power of the controller, the maximum speed of the controller's serial port, and the latency of the analog-read pin, so if you have a controller where all three are stronger, then you would get a better oscilloscope bandwidth definitely. Almost all the processing is done on the PC: All the controller is doing is reading and sending over the raw number. So it should work with everything.
It is refreshing to listen to someone who thinks and communicates clearly.

Very interesting. Keep up the good work, and hopefully your channel will start getting the views it deserves.
im sticking this video into my favorites
Nice video, thanks for taking the time to make and share this.
Very impressive. Showing my lecturers this in college. I think you can teach them by the way they reacted
Awesome mate. Great video and clear explanation.
Very straightforward exposition. Thanks!
14:52 "Apparently someone is mowing the lawn... in the middle of the night."😅 Great video, thank you!
Brother, that is amazing sharing knowledge. Very interesting. Keep up the good work
Cool dbz poster 👌🏻 awesome video

Wow....Mind Blown..
The Rigol 1054z is a great scope that is relatively inexpensive for what you get. ($350)

great video, funny and informative.

Hey, guy, thank you, for your great explanation and for share your knowledge .. great channel.. I'm subscribed
Great Stuff
Good work
i love you man. you ar ethe best
Where are the subtitles?

muy bueno! me sirvió
What is the aplication and full code
Have you published links to the Unity game engine code and will that run on a Raspberry Pi ?
It should run on any Arduino since I used only basic functions, but I can't guarantee it since I can't test it myself on other models.

@@simplyput2796 please do include the link. I didn't find it yet !
What about if try it in a faster controller, like an esp32?
It's limited by the processing power of the controller, the maximum speed of the controller's serial port, and the latency of the analog-read pin, so if you have a controller where all three are stronger, then you would get a better oscilloscope bandwidth definitely.

But I do still like your material
You humans think you're so smart. : )
Good video but his voice is so accidentally condescending
