Today's project, I will create an oscilloscope from a cheap bluetooth headset You will have a bluetooth headset, A smartphone with oscilloscope software Need 2 resistors 100K or 200K and 1K It forms a voltage divider 33V zener diode to protect bluetooth headset The measured frequency is dependent on the quality of the headphones However, if the frequency is below 10Khz, it works quite well I'm not sure the software will work with all phones If it doesn't work, try another software, find the oscilloscope on google play br brIf you like my video, give me a cup coffee Thank you very much brDonate : wwwpaypalcom/paypalme/phdhung brFacebook group : bitly/CreativeElectronic brContact: Magnetron0989821611@gmailcom brPhone: 098982161

i found it hard to see the readings ,how close were the android reading to the real oscilliscope readings?
Comment from : Katie Mcgilchrist

After watching the video and reading tne comments:br(There is NO negativity in my comment fyi)brbrI am compelled to comment on the failure in removing the battery BEFORE any soldering & or modifications I feel no need in explain why one should or should not remove ANY connection of any value of a power source to such device/object "to each their own"brbrIt go without saying i clicked on the video because i AM interested I very much enjoy seeing what people do or get done to work for them brbrIs a good video brDespite any negative feedback anyone may say, your video IS very informative This IS a good idea that can & do & may hold a valuable purpose for person who not have the means or ability to aquire (lack of better word) a bench or lab scope
Comment from : Eric the (not really) Jew

not all phones work, possibly works only on samsung 7 which has a receive bluetooth option, android phones usually are in the transmit mode which cannot receive bluetooth audio i think bluetooth dongle with transmit mode can be used to connect to bluetooth receivers option as in samsung 7, bluetooth headphone is more complicated

Muy bueno pero no hay diagrama del divisor de tensión para poder armar bien el circuito

very Nice going to build one 👍

I cant see you connect zener with 1k to gether or 200k ?!

Why my Bluetooth device mic doesn't give signal even after connecting but phone's mic does

Its not working, i have the same bluetooth, same zener and same resistor, but doesnt work, phone is samsung

Comment from : RATNESH SINGH

So you got it to send a signal to the phone & o'scope app, but the o'scope is free running! That includes your actual o'scope on the shelf Your can't measure anything like that! Do you know how to use an o'scope?! Much more useful if you set the TRIGGER level to freeze the display, to be able to actually see a waveform change over time! That way, your can see changes and make measurementsbrAlso, if zener is going to ground on the earbud, not sure it's "protecting" the circuit You'll need another zener to do thatbrHowever, besides these concerns, I do like the fact that you've shown ppl how to use simple tech to accomplish other things, to get ppl to start "thinking outside the box" so to speak brThanks for that!

Comment from : cristian popescu

Very good
Comment from : Cesar Jorge Murillo Barientos

For ac protection, the zener diode should be connected to the circuit again in parallel but in reverse in two series I think there is a mistake in the project

Nice Im try this but this program can't support blotooth mic

Comment from : Jonny Hoareau

How do I get my scope app to read input from Bluetooth or wired microphone? It only responds to cell phones internal microphone
Comment from : uRealReals

SUPER!
Comment from : Максим Дор

You should use two zener one pointing the opposite of the other Think you didn't use the other one because the microphone was polarized and you didn't detach the resistor that was powering it
Comment from : Thebasicmaker

which resistor is parallel with zener diode? 1k or 200k ?
Comment from : AT Eng

Hi, bro Any input voltage up to 33, in the phone is 30 brWhich is the relation to know the exct voltage? brby example: if i have 5, 9 or 12 volts in the phone is 30 brhow i can measure de voltage or only can measure frecuency?

Can I use a 35 volt zener instead of 33 volts
Comment from : Ahmed Ali

Can I use a 4 volt zenner instead of 33 volts
Comment from : Ahmed Ali

Sir, nice work Can we measured bios ic signals and lvds signal in of lcd tvthankspl reply
Comment from : ND KADAM

SmartScope always choose original microphone on phone is main source, how can you set this app use microphone on bluetooth headset ??? This video is fake

How do you set the app to take sound from the Headset? For me it takes from the phone microphone only, or 35 mm jack wire
Comment from : Jaroslaw Aske

WHY keep the cable instead of attaching it directly to the probe?

What is the peak voltage range ??

It would be Good if you use tvs diode or MOV

Comment from : Paulo Lagoela

Ok, you get the waveforms But I am wondering about the signal mesurements How can you adjust the scale? The signal crossing a tension divisor and a bluetooth volume control how I know if I am looking at 2V, 20V?brIts not a simply 1x/10x probebrThank you about your video

Can u please tell me the connections bro please, I am fully confused
Comment from : sai surendra

Can I use 390k ohm resistor alternative of 200k ,,,, what is the max input voltage
Comment from : sai surendra

Cái này cũng rất tiện mình đã dùng bằng rắc tai nghe kể cả bằng Bluetooth Nhưng nhược điểm của nó là không đo được tần số cao, chỉ đo được 20khz đổ lại thôi, đo xung vuông của TL494 hoặc SG2535 nó tầm 25khz là không thấy xung Nghịch bằng tai le bluetooth thì không sợ bị hỏng điện thoại😀😀😀

Can it measure voltage mains at home which is 220 AC ? or is it for low voltage ??

I lucked out my headset pcb was through hole super easy and my headset handled 5v without any smoke
Comment from : Q&R Electronic repair

Like this as it's totally isolated Not to clear in the video but I suppose the 3z3 is across the small resistor I would be moor tempted to fit a bnc socket to the BTooth adapter Just for interest what's the frequency response?

Comment from : Electron Resonator

Great idea 💡 , but sir instead of only music, explain what you're doing step by step Similar way can you make a video on RF transmitter and receiver module explaining the circuit diagram step by step, but no background music
