    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.

    🇦🇷 Llegó bien, solo se retrasó 2 meses en la aduana de mi país (ARGENTINA), fácil de armar, tener en cuenta que la alimentación debe ser de 9 volts estables, sino la lectura es erronea (y esto dificulta la calibración). Así parece ser una buena herramienta para pequeños proyectos!!!! Muy conform!!!!

    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.

    The manual is actually great! Easy to follow, with lots of pictures and helpful explanations. It was a fun little project and worked immediately as described. The display is of good quality and easily readible. The case feels pretty solid, the buttons as well as the control knob are of good quality as well. It is not suited for high-frequency measurements. For the price (~15€) it is a steal.

    kit diy oscilloscopio da montare,componenti discreti,resistori,condensatori,connettori vari,interruttore,deviatore,parti assemblaggio contenitore...taratura finale di due condensatori variabili.Vale per quello che si paga,non è precisissimo nei valori riscontrati(nel mio caso rispetto al tester risulta di 1 volt circa maggiori)ma lo si può considerare come strumentino didattico.molto bello il display.

    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...

    This constructor is simply magnificent. It gathers in one breath in a couple of hours. Assembly instructions are very accurate. There is one drawback, resistors and capacitors + - a couple of kilometers. I bought 1% soldered and enjoy the device. The best whale that collected.

    This little pocket scope is excellent considering the low cost. The unit comes packaged in a box with all the parts required. I enjoyed assembling the kit which is high quality. The instructions are very clear and explain everything and it builds well with no problems. In use the display is very clear considering its small size. The operation of the product is simple and works well and has useful functions such adjusting the trigger point and being able to capture and hold a waveform. The stated
