Lm39 it's simpler

I'm not quite sure if it makes sense but have you tried to solder in a bigger display?

What to do if my PC and laptop already have com3 assigned for something else?

How to change the waves forms?

Can you explain how to press the button to record? I don't know how to use the type of button you use, can I use dipswitch instead?

You didnt install a battery on the oscilloscope

Why no one specifies the polarity of the power supply like it does not matter ?????

Some of DSO150 have a trigger voltage dispay at the right down corner. My instrument don't have. How to fix that?

The info was excellent - and - your video style and presentation was perfect !! Thanks !!!

First of all, I congratulate you for the very instructive videos, on the occasion I ask for advice on how to view the trend of the wave of a 220V inverter produced by a photovoltaic panel that charges two batteries with a charge regulator , given that with the oscilloscope, like this one, I have seen that the probe cannot exceed 50 v, I await an answer thanks.

😀😀😀😀😀

Just bought mine yesterday and there's no signal

At 11:37 the signal looks like composite video signal..

Como reseta ele?

I also bought that oscilloscope and the truth works very well. But it is limited (according to the designer) up to 200 khz. Is there a way to modify it so that it works up to 1 Mhz or maybe more?

still seems to have a more reliable trigger than anything by hantek.....

Wait...i have read somewhere if I install update that screen will say "this board is fake" and that is it.Is that true?

I convert vintage Valve / Tube Radios into Guitar Amps, my Oscilloscope broke and because their essential to my process i needed one. It must not break the bank and it must be pretty mobile as i have a couple of benches in different rooms. If your a hobbyist and your doing electronic projects these are a must. Test equipment can be expensive so this was ideal. It's not bad for £22. The 2 channel model is only £44 so i may invest in one of those if i cannot find a replacement CRT for my main one.

Does this pickup pure sine wave? Thanks 🍺

Is it possible to upload with an arduino configured as a programmer?

set up easy

Needs some care

How to factory reset it?

was looking for a manual for this device-this is one of the best to be found!! thank you!

Excuse me. I found it with code

very good job. Where I can find the circuit diagram for this project

Good video but go slower with your explanation so we have time to follow on-screen and voice, remember you know we don't!!

Hey can you share the firmware for this is this is open-source

i want only to record audio in sd card so pleas can u give me shematic diagrame and code

Would this be sensitive enough to test for the outside foil on capacitors? Would be handy if something this small is capable of that.

Shame they didn't have these kits when I went to tech school. We had the analog and digital multimeter kits back in 95-97.

Great video.

Can you give me the pin connection schematic? please? Gmail [email protected] thank you so much.

That's strange. Mine came fully built. Only had to plug it in.

Can I use on a 120v 240v inverter ups. All I want is something cheap to see if this one I got is pure sine or square wave. There is no markings

On my scope of this model, I could not get the waveform SAVE and RECALL function to work either. In my own tests, I found this scope worked well, with reliable functionality, display accuracy and measurements, as long as I did not try ans measure signals much outside if the audio frequency range. I thought it might be useful in a technician's toolkit where they only need to work with lower frequencies. I discarded the cheap, short, unshielded test leads that came with the scope, and substituted an inexpensive scope probe...it was a 1X/10X probe, but the scope gave worse results when the probe was set to 10X, so I only use it in the 1X mode. The things that impressed me about this particular scope: - the user interface and controls and display colors and indications are well thought out and coordinated - unlike pretty much ever other inexpensive kit scope, this one has a much more useful form factor, and the nice case coming as part of the kit is very good I would not call this scope a 'toy'. Its functionality is better than many basic analog scopes, and adds some of the useful features of a DSO.

Why dont u show what your leeds touching ?

Thank you very much!

why so complicated just for updating software? anyway thank u for sharing.

hi could please make a tutorial on this

Better idea is buying Hantek 6022be and connecting it via otg to phone with H scope app. It's only 60$, but it has 2 channels and 20MHz bandwidth.

I was thinking of purchasing on of these to test the foil side of capacitors, this video was well viewing I wll watch this again... thank you for posting this...):

If one has a stlink v2 usb programmer/debugger, you can use the swd interface to program it instead of the uart interface. That way you don't have to solder the jumper bridges

please make a tutorial on this
