- Опубліковано 6 жов 2024
- This circuit is one of the simplest and cheapest circuits to test LED, TV backlight, and diode test.
don't forget that there is a risk of electric shock.
when using this circuit, so be careful not to harm yourself and others.
💥This circuit is just an LED tester, not a driver for LEDs💥

سيدي المحترم لكم تحياتي وتقديري على مجهودكم وفيديوهاتكم القيمة التي استفدنا منها الكثير اسأل ألله عزوجل أن يحفظكم واسرتكم المحترمة من جميع شر خلقه وفقكم الله وسدد خطاكم دمتم في عز الله وأمنه ورعايته والسلام ختام
شكرا لك صديقي العزيز
This video is fantastic! The detailed instructions and clear visuals make it so easy to follow along. I've been looking for a simple and effective way to test LEDs and diodes, and this DIY solution is perfect. The step-by-step guide is thorough and leaves no room for confusion. Thanks for sharing such valuable information. Keep up the great work, and I can't wait to see more of your projects!
Thanks❤
Thanks.....😊
很危险的事情，不是专业电工更不要跟随，一不小心可能会做成触电或其他事故！
Better we can use Power Supply or adaptor multi

Thanks bro
From an electrical safety point of view, it is dangerous.
Yes
Hay lắm rất tuyệt vời cảm ơn bạn nhiều chúc bạn thành công trong công việc cũng như trong cuộc sống hàng ngày
Thanks bro
Al fin un probador que funciona. Buena idea. Gracias.
这样做太危险了，一不小心可能会触电或做成其他事故，而且灯泡故障不是经常发生，搞一个“测试器”也要时间和金钱。买一个新的灯泡花几块钱，不要因少失大，误了生命！
Ni idea tienes de lo que dices 🤦♂️ jajajaja
parabéns por este vídios tão bom , gostei muito muito ,vc é um profissional , capacitado , obrigado,
The quality of the image in the middle of the video was excellent. Have you done anything special???
Thank you for your attention to the quality of the video
Yes, the video camera unfortunately burned down and I had to buy a camera with a higher quality
It can test many leds in series but potentially dangerous. So add a fuse for safety.
Thanks bro
Excelente video, saludos
Una pregunta…para corriente 120 ca …cambiaria su resistencia?.. pregunto
Se encenderán más débilmente si pones las mismas. Este suministra una corriente media de alrededor de los 10-12 mA a 230 V porque lleva dos resistencias de 10k (20k efectivos). Si es para 120 te generará alrededor de 5 mA. Si quieres puedes poner dos resistencias de 4k7 o 5k6 para hacerlo similar.
Use the same values for 120 volts
Εξερετικο πολύ καλό το κύκλωμα μπράβο 😊

Thank you for your tutorial Sir
circuit is very very simple
such a bad idea and construction
and some ill-informed comments
First this is DANEROUS - it is not isolated from the Mains voltage, so a nasty shock - even a fatal shock is possible.
The voltage at the probes is over 300VDC
VDC-peak = VAC rms x 1.4 - Vf of diodes
That is a standard well-known equation - this guy says its 0 to 200DC which is nonsense.
While the resistors limit the current - a small current at that voltage is dangerous
Another point is that LEDs have a low reverse voltage rating so this high voltae coud damae a LED. A led tester that can damage the DUT ------ not smart at all
then the construction sucks. The resistors should not be soldered directly to the prongs. And there should be better strain relief. Plus the wires need to be rated for that voltage
In conclusion a bad and even dangerous circuit that is poorly constucted.. It is clear to me that this guy lacks knowledge
