    I have modified it to work with a li-ion battery with mt3608 step-up converter and tp4056 usb li-ion charger. Also, the battery itself has a protection module. Now, it can also output on 9v dc, so I can use it to power other devices. Seems to work without problem. I have not removed R30 and did not use the switch, instead, I have connected a switch directly to the output of the battery.

    lo tengo parado por que he debido de conectar mal algun condensador y no me hace bien las lecturas, la verdad es que soy una persona muy maniosa, se soldar a nivel profesional y estoy muy familiarizado con la electronica, y compraría el oscilosscopio ya ensamblado, por que 2 horas no te las quita nadie de buscar resistencias, comprobar que estén todas, que vienen bien de fábrica, que van en su lugar...

    Good item, genuine by checking the SN. Overall, this unit delivers a good opportunity for those, engaged in amateur radio as a hobby with no access to professional equiment, to take a look at the small oscilloscope in order to understand whether they need a more professional device and to understand the basic principles of the oscilloscope.

    This is a very good small and portable oscilloscope. It is a very good choice for amateurs who are interested in electronics. It is easy to assemble, it took me roughly 1.5 hours to finish everything while I was explaining the whole process for a tutorial video. So, maybe it can be finished within less than an hour. Screen has good brightness and high enough resolution, so it is easy to read it. Buttons click well, knob rotates smoothly. The attached instructions are clear and very easy to follow.
