Ha van rajta RCA vagy Jack bemenet, akkor azon keresztül lehet neki beadni a füllhalgató kimenet jelét egy alkalmas készen is kapható kábellel.

@@bzoli5706 A TPA3116 blutuszos Jack bemenetén keresztül lehet hallgatni az internet rádiót. Telefonom kapcsolódik a Wifihez és az meg összekötve jack -jack vezetékkel és szól az erősítőn keresztül (hangszórók) a zene. Köszönöm a választ.

Megnéztem, de nincs rajta ilyen kimenet. Talán azért, mert a többség, hogy olcsóbban vegye krokodil csipeszes 1:1 kábeleket kap hozzá. Csinálj vagy szerezz egy jó jelalakú 1kHz körüli négyszöggenerátort és azzal be tudod állítani. A régi szkóp jele is tökéletes.

@@bzoli5706 Köszönôm a választ!

I am a teacher and I use it in a school, and it gives some extra protection of the screen.

The triangle wave is symmetrical, but our signal is asymmetrical, called sawtooth.

I will try to show it somehow, but now here is a short list of the IC-s and their tasks. 74HCT14 oscillator and inverter for counter resetting from IC 138 output "7" 74HCT393 2x4 bit binary counter as 3 bit 0-6 counter for column addressing, X deflection 74HCT138 Decoder from 3 bits to 8 outputs, activates the cathodes of the display columns, deflection X LM324 Quad-OpAmp as a 4-piece comparator for ADC function, Y deflection 74HCT86 Quar.ExOr always only the largest of the comparator outputs is high and drives the anodes of the display rows through 270 Ohms, Y deflection

This is a small-resolution screen digital oscilloscope model. The signal comes from a function generator.

@@bzoli5706 Very COoL! Thank you for the reply. Cheers from So.Ca.USA 3rd House On the Left

When switched to SN ON, the radio does not produce any hissing noise when there is no transmission. SN stands for 'squelch', which is used to suppress the background noise when there is no signal. I don't understand the 2nd question. 😞

Дякую за позитивний відгук, радий, що моє відео було корисним.

Thank you for your feedback. I'm glad that my video was helpful.

Köszönöm, ha szétszedted és lefotóztad elküldhetnéd a képet!

In my opinion, the video is not meant for reading out the technical specifications. That's what the product's linked webpage below the video is for.

@@bzoli5706 but product web page dont say nothing about vertical sensibility, only current sensibility... that info is missing from web, and if you already have, you can measure his voltage sensibility, but only if you want

There is no FPGA! MCU GD32F407VET6 + ADC MXT2088

I don't think that the Microcontroller can do all the work for a 10MH dual channel DSO. ​@@master_codings

I am very glad that you found my video useful. Thank you very much for your feedback.

Спасибо за просмотр и отзыв. К сожалению, единственный способ попасть внутрь устройства - снять экран, нагрев его, как это делается на мобильных телефонах.

@@bzoli5706 Спасибо за ответ. Понятно. Ремонтопригодность = 0. Устройство не ремотируемо - одноразовое. Но за такую цену чего хотеть? Я начинающий радиолюбитель в 53 года. 🤓 Выбираю недорогой осциллограф. Предпологаю использовать для безтрансформаторных блоков питания и датчиков автомобиля. Хочу 2 канала и цену до 100€, если сожгу, чтоб не жалко. DSO2512G - 78€: имеет видео выход, но слабые характеристики. У DPOX180H характеристики выше, но цена 122€. И ещё понял, что очень много зависит от щупов, их можно (нужно!) покупать хорошие (дорогие) - они не сгорят... Спасибо Вам за ответ.🤝 Доброго зоровья!👍

@@user-jy4gs1zw1b Все ремонтируется и греть экран не нужно. Это бред ) Мне пришел прибор с отслоением стекла от корпуса , пришлось разбирать и приклеивать стекло заново. Стекло пластиковое и держится оно на каких то клей соплях )) i.postimg.cc/d3hzLj7Q/IMG-2264.jpg

Привет земляки!Китаец закрылся от мира - невозможно с ним связаться! Тот сайт что в инструкции полная лажа там все еще firmware V1.86/V0.6 И нет обратной связи! На том сайте есть ссылка на baidu диск, наблюдаю примерно раз в неделю обновляется дата файла прошивки Там уже V1.98/V0.8 версия.

Китаец постоянно допиливает ее. Но скачать с baidu еще та проблема нужен китайский номер для регистрации на сервисе! У меня только европейский. Кто сможет пожалуйста скажите китайщу пусть добавить Аналізатор спектра FFT!!!

I also like and have Siglent SDS1024X-E with logic analíser extension. And a four-channel portable Micsig is my second favorite.

Thank you very much.

Köszönjük. Nem volt sok idő az elkészítésre és ez egy nagyon sokat tudó szerkezet, a gépkönyve 355 oldal. Típusszám alapján találtuk meg mi is.

Thank you for your approach. I used the clock because it was the simplest signal source requiring X-Y mode, and many things were easier to demonstrate on it than with the Lissajous curves.

can't do this on a digital scope: ruclips.net/video/4gibcRfp4zA/видео.html

First of all, you need a microcontroller. I recommend the At89S51 and 52 types. And you also need a programmer, either a USB one that you can plug into the on-board programming 10-pin connector, or one like the TL866, into which you can insert the IC. The easiest way to write a program is with the Mikroelektronika C 51 IDE.

What do you mean in this sentence? "A No Dees and K No Dees 🤭 best stick to your fine british accent."

watch the video near the end. the computer generated voice cannot pronounce Anodes and Cathodes

Dear Allan, Thank you very much for responding and clarifying the issue with the TTS pronunciation in my video. I wouldn't have realized this on my own, and even after consulting several AIs, they couldn't pinpoint the problem either. Interestingly, the TTS incorrectly pronounced embedded terms like "MHz" in the script but correctly when isolated. I managed to fix this in the video by editing it. However, I didn't notice the mispronunciation of "Anodes" and "Cathodes", partly because I know the script by heart and also because English is not my native language. Regrettably, as far as I know, it's impossible to modify a video once uploaded to RUclips. I would prefer to correct these words if I could. Could RUclips's own editor offer a solution? I'll look into it. Again, thank you for your helpful feedback. Best regards, bzoli57

Sorry, but I can't imagine what you ask from me. :-(

Szia. Köszönöm az érdekes megfigyelést. Itthon most csak a nem beszélőset tudtam tesztelni egy tápegységgel és biztosan 6000 countos. Viszont kapacitásmérő üzemmódban az ujjaimmal szorongatva modelleztem a kondenzátort és ott tényleg 9999-ig mért mielőtt méréshatárt váltott.

I'm not a big believer in remote diagnosis, but since it's Christmas, I'd like to help. I would like a more detailed description of the problem. The first 10 LEDs work fine and then everything goes dark? Is there still power consumption? Is the 555 giving the clock signal? Do you have any instrumentation to measure the circuit? What happens if you press the pause button for the first 10 seconds?

@@bzoli5706 thank you for your time. No, everything turns on; time, leds change each second, buttons work to change time, etc. however, after approximately 10 seconds, it turns blank. I then give the power source a jiggle and it comes back on, for another 10 seconds….

@@gugzy could you make a non-public video about these phenomena?

@@bzoli5706 turns out it was my power supply. All is well now. Thanks for your support.

Elkérheted, de miről akarsz írni? Nem tudok spéci kérdésekre válaszolni.

This SAFT battery is for the RAM card seen in the video, it must have been used elsewhere, but I don't know those places. Tadiran cells were originally used in an 8080 industrial control board.
