Very, very well done vid! Excellent content. I'll put this together during tomorrow morning's coffee. As an engineer, I had thousands of hours of scope and logic analyzer use under my belt. Now, 20 years later, I'll purchase a $400 200Mh scope from Amazon, but not for several months. A few years ago, I watched a similar vid but never followed up in it. I will this time because I actually have serious use for it now. Thanks for producing this vid. It's very timely for me. You really did a good job.......
Hey. Would it be possible to use the Pi Zero 2W ? And can you put out the signal via Composite? I am converting Tiny 5 inch CRTs to portable Arcades and thought if it already has a Pi why not include an Oscilloscope application as well?.

sorry for noobiness on this one ,what whould the main benifits of using the pico ,compared with say a bunch of resisters straight into the headphone socket type of build ?
I'd say few benefits 1) using the mic input you can display the waveform but you can't know exactly the actual voltages 2) the sampling rate of the built in microphone is very limited 3) the voltage range of the built in mic is definitely smaller then 3.3V of pico and therefore you need to use much higher resistors divider which lowers the resolution and quality of the signal visualization 4) if you connect the headphone and something goes wrong... you may end up with a broken phone which costs much more than the pico 5) the pico can also have a wifi module and the phone can display the signal in full wireless mode
Excellent job there, very well done with tons of potential for future projects. Thanks a bunch for the app - I immediately got the paid version and subbed to your channel. Keep it up!
Hi Great Tutorial, can we also check negative signals using this, for example +- 12 v PWM signal, what would be setup on Pico side to measure negative part of the Signal. Thanks
You'd need to use a voltage divider or something similar to bring it into a safe voltage range and for the negative voltage handling I believe there are some chips that can detect a negative voltage but you'd need to get the voltage as a positive value as you'd break the pico otherwise. Then with software you detect whether a pin for negative is high and then take the input of the divided voltage multiply by what it was divided by and then by 1 or -1 depending on sign. At least afaik
Hi, I'm not an expert and would like to know if with this oscilloscope is possible measure also the sine wave of the 220 volt elettric current we have at home ....Thanks

Amazing tutorial, I just loved it. Very detailed. thanks
The limitations of this solution seem to be the very limited voltage range and probably the sample-rate.
How about 2 channel?
What pin are used?

I wonder if this could be made to work wirelessly with the new pico w.
it is working and j am using
@@shauryaaditya169 can you please share the method for PicoW ?

Do scoopy has wifi or Bluetooth

@@halnovemila9698 yep ive got you, i have a spare pi 4 the code should be ok for that to shouldnt it
& how to build 2nd ch for premium upgrade version?

Where is the software?
please what is the maximum voltage and frequency this oscilliscope can measure
Dear sir, I have failed to firmware pico(made in India). Request to make a long video about firmware
Excellent 👌👌👌👌👌
Sir please make a video. To test 555 ic multivibrater usin pico pi oscilloscope
Is it working on esp32 ?
Can i use arduino board instead of rasp pico ?
no.
the potentiometer is 10k or 100k ?
I dont know English very well
Plz tell me what is maximum frequency can i measure using this scope?
What i can use arduino uno on this application scoppy
aurduino wont work.
Nice
فكرة مفيدة للغاية

ruclips.net/video/L8MfcUX7NTg/видео.html at around 4:44, its possible, something about making a floating ground to make that work.

I have only arduinodroid coding app how is that?
Amazing !
What is the bandwidth of the scope 1MHz or higher?
more like ~100 kHz
Why you used a 100k and 1k resistors excactly ?why not 120 or 220...
1/100 of input voltage. for normal value in osciloscope (1/100 of input).
@@orkoteg09 Can you explain more sir ,and thanks
Can I see the sine wave
Awesome.
Post more video bro
Great !!!

Max voltage to be measured
Wow!
A 1kHz scope!
For only $5 plus a $300 'phone.
Hahahahaha, you already have a phone.
@@ElectroniClinic I already have a Tektronix 'scope.
By your strange logic:
cost of 100MHz scope: $0.
@@ElectroniClinic or a $50 amazon fire tablet maybe
What a dumb comment. It is assumed everyone has a phone.
You can probably do a better one with a bluetooth bud and audio oscilloscope app
Plz reply ...
