Assembling and Testing the 20€ DSO138 oscilloscope

The DSO138 is a 20€ digital oscilloscope kit made by JYE Tech. This video describes the assembly process and shows the first test of the finished device.

You the first person I know that got instructions from a Chinese kit.if I needed a scope I would do like the other guy and buy it already assembled, great job on yours video...

Nice video! Can you make a video on the practical uses of the DSO138 oscilloscope? I want to see how it is used in actual electronics trouble shooting. Thanks! :)

Thanks for the video ! This little device looks very intersting for the price !

Hi, maybe some one knows how to do this. in the instructions says "Serial output of waveform data. This means captured data can be saved and displayed by PC. For example, this photo shows a captured single byte (0x35) sent from a serial port at 115200bps. This photo shows the same waveform displayed on PC using Gnuplot."
do you know how to get the picture on pc?

I got mine from China. Come fully assembled and works great.

If you use it on battery, does it have "low voltage" warning as the battery draining?

Warum packen die nicht gleich alle Bauteile als SMD auf die Platine ? Das wäre viel besser als diese Fleißübung.

can i buy something from you? if so, how and can you ship to u.s...plz let me know...

As someone who has written several handbooks/instruction manuals, there is no such things as idiot proof. There's always a bigger idiot out there somewhere.

Said before but this is NOT the Mini :(

May I ask where you bought that?
Don't buy one from BangGood or a 3rd party from Amazon, I got screwed both times. Both were counterfets. First one seemed legit until I couldn't get the damn thing to work. I went digging around and found out the from JYE Tech that the circuit board was different then they put in their kits and the firmware was older and told me it was a counterfet. I then contacted BangGood and they told me they get them from JYE Tech. JYE Tech's sales support said they never did dealings with BangGood. The second one from Amazon I didn't even bother try putting together and trashed it since the instructions were photocopied and the JYE Tech logo was wrong it said "JYE Tach".

I got the whole story about it on my blog, comes in handy to point out a counterfet and how dealing with the saler went nowhere.
