This is a really helpful video. I bought one of these but haven’t used it much as the manual is so poor. I couldn't figure out how to get it into lissajous mode. Why do manufacturers of such good products let themselves down by not creating proper instructions? Thanks for making this great unit work for me.
Egy kérdésem lenne ez a rádió összeköthető-e egy erősítővel a fülhallgató kimeneten? Van egy "Bluetooth 5.0 100W+100W TPA3116 Digital Audio Power Amp HiFi Sound Dual Channel Class D Stereo Aux TF Card Amplifier Board" erősítőm. Hogyan tudnám összehozni őket. Én csak amatőr vagyok az elektronikában.
@@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.
Thank you sir. Very useful. Looks great. Id only be worried about durability. I’ve had a different but similar single channel bought on Amazon that died after a year of light use.
Köszönet a tesztért, nagyon jó lett. Egy kérdésem lenne, a szonda hogyan kalibrálható? A régi oszcilloszkópomnál amikor hozzákapcsoltam a szondát megjelent az 1kHz-es jel és ezután csavarhúzó segítségével tudtam állitani. Üdv.
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.
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
Valaki kérdezte az IC-k típusait és funkcióját. 74HCT14 oszcillátor és inverter a számláló reszeteléséhez a 138-as IC "7" értékű kimenetéről 74HCT393 2x4 bites bináris számláló mint 3 bites 0-6-ig számláló az oszlopok címzéséhez,. X eltérítés 74HCT138 3 bitből 8 kimenetre dekodoló, a kijelző oszlopainak katódjait aktiválja, X eltérítés LM324 Quad-OpAmp mint 4 darab komparátor az ADC funkcióra, Y eltérítés 74HCT86 Quar.ExOr a komparátorok kimeneteiből mindig csak a legnagyobbat engedi magas szintre és 270 Ohmon át meghajtja a kijelző sorainak az anódjait, Y eltérítés
Thanks for the video. Good job on describing the functions as I could not find any manual on this FM Receiver. Two questions: When you long press the frequency knob it scrolls "SN ON" or "SN OFF" across the screen. What is SN? Also can you wire a AUX(3.5mm) jack to this board? If so, how will it switch between sources?
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. 😞
Great Engineer SC02 oscilloscope video. I purchased a SC02 to keep with my op-amp breadboard accessories. It seems to function OK. However, the information is limited and the bzoli5706 video is a great help. 😎 Thank you very much.
Frissíteni kéne a szoftverét, sokat csiszoltak rajta. a dobozában volt egy QR kód az oldalhoz. btw simán lejön az előlap egy pici hajszáritó melegítéssel, 4 csavar tartja egyben.
Hello! I upgraded my Engineer SCO2 oscilloscope. Now I have software version: V1.98 (2024/03/04) Search on Google by request: "firmware for the Engineer SCO2 oscilloscope!"
@@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
Thank you very much for this. I have had this scope for a couple of months now but didn't really know how to get started with it. I'm very new to electronics so this video helps a lot.
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!!!
What's your favorite manufacturer for digital, including scopes not shown? I am impressed by the Siglent, though Teledyne and Tektronix are some of my favorite
That was a great presentation. The speed was perfect even for an amateur like me to follow and understand the presentation. Thank you sharing the knowledge, keep up the good work!
The only useful advantage of an analog oscilloscope occurs when observing Lissajou figures - e.g. when tuning clocks, sine wave generators, PLL systems, etc. XY mode for observing magnetic hysteresis or other "one-off" waveforms on a ~$400 digital oscilloscope works even better than on an analog oscilloscope. Displaying a "watch" on an oscilloscope screen is a joke!
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.
Ok, I just built this board today. Now what? Which microcontroller and IDE should I begin with. I can operate the Arduino environment successfully, So I'm up for something new. Subscribe and can follow. is the 8051 something to do here?
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.
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 RU-vid. I would prefer to correct these words if I could. Could RU-vid's own editor offer a solution? I'll look into it. Again, thank you for your helpful feedback. Best regards, bzoli57
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….
I used to have these exact cells on memory boards that, for unimportant reasons, ended up in my hands. I'm not surprised, they lasted ~20 years with an sram, provided that the board was thoroughly cleaned (water cleanable flux is quite conductive). My pet theory is that since they are potted, they are more resistant to moisture ingress than the button cells - though I never sawed one in half to see what they are on the inside.
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.
How hard is it for a director to just search for a video of this happening for real, the version in the movie is so much less exciting than what happens in real life if you do this.
Analogue oscilloscopes often have a Z modulation input which can help give better displays. I think this clock hides the darkened areas of trace by moving fast : the Siglen in large-memory mode catches even this but does not apply it to the persistence modelling. I think you chose variable persistence on one scope and varied the sample speed or length in others, probably to show each at it's best but didn't explore it too far.
