Home Made LED and Diode Tester Auto Voltage / Simple and Useful
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💥

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

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.

@@vijaymhatre2676 Because you can die. The resistors are 10K/0.25W. If you short circuit the resistors get too much power and can damage (in this video at 4:53) P = 230V*230V / 20000 Ohm = 2.645 Watt 2.645 more than 0.25. Nobody guarrantees the resistors no lose them value. If the circuit shorted and you contact pins you can get more than 20-30milliampers and you will be died. If you do not know and do not understand safety regulations and sources of danger you do not use 230V (or more than 40V Voltage) The idea is good, but you should use less than 40V instead of 230V. For example an 18V accu is good for this.

The point is that the electricity is dangerous. More than 40V can cause damage. If somebody use 230V (100-250V) the safety regulations must be followed.

Perfect way to shock yourself or burn wiring in your walls wirh short circuit🎉

Hi dear friend. Wouldn't it be better if you watched the video till the end and then judge?? This circuit does not cause sparks and damage to home or work wiring. You should read about rectifier diodes

20k impedance ! No short circuit but resistors could dissipate both more than 1W. Maybe is better higher power capbility instead 1/4 W
Don't do it ⚠️⚠️😡 Danger, Danger 👈
Wrong 😅

guys, chill out. its only an LED tester and not a Driver... i do use one but with different applications... much more complicated than this circuit

such a bad idea and construction First this is DANEROUS - it is not isolated from the Mains voltage, so a nasty shock - even a fatal shock is possible. The voltage [for 220VAC mains] 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 could damage 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
Don't try at home💀💀💀

Please listen to our dear friend
Нельзя делать устройства с открытыми проводящими элементами, не имеющими гальванической развязки с сетью! А если случайно этот прибор в руках ребёнка окажется? О последствиях задумайтесь! Сколько людей получают травмы и гибнут от таких лайфхаков от непуганых тупых идиотов! Нужно запретить размещать в интернете такую опасную информацию!

Foolish method.
