Cool project man 🔥🔥🔥

[@nachorodriguezhansen8273]

very nice gadget! just a few comments. if you're trying to measure usb standard devices with different charging protocols you may need to connect the data lines to the different usb connectors and maybe solder the board with thiker wires. And if you want to improve it to a higher level i recommand you to include a mcu to the design and also mesure capacity and othe stuff

Great video as always I especially like this USB Dr. Video since it can be used at more than 5v to test adapter. Is there away to wire it to test amp that is from the power source before a out source is plugged in to the Dr. Maybe thru a switch with a diode????? But if not still a great video, I'll defently be make 1. Thanks again and keep it up!!!!!

[@itz_ricky2825]

11:11 it'll not take more power then 0.75 amps without the data pins if you connect the data pin so it'll communicate to charger or connect some kind of resistor divider between all usb pins(+ve to resistor to both data pins to resistor to -ve)

Hello, I wish you happy days
It is a pity that we live in Iran and we are being crushed under the pressure of US sanctions. No electronic devices can be found due to the high cost of the devices.
I'm so glad you made it

[@kshitiznavediya9470]

That's really bad

[@mgm5457]

Well ... has Iran threatened the US ??? ... don't play nice, bad things tend to happen ... not the average Iranians fault - some power hungry politician probably !!!

Volt ammeter doesn't show the current correctly if you don't use individual power supply for it.

[@Hacktuber]

?????

[@shadowhunterxxx5891]

@@Hacktuber just measure current with a multimeter and your diy device.this module show the current correctly if you connect the red and black wire to the another power source.otherwise because of common ground wire between power supply and ammeter the device show the current wrong value

[@balajisubbaiah]

Either the Volt-Ammeter module from Aliexpress is bad, or the Ac-Dc Apator you used to check the voltage is very bad. 18.9 volts when the slider on the adaotor is set to 12V? That's way too bad man. Even the label on the adaptor shows max 12V.

Basically: The United States since 1979 has applied various economic, trade, scientific and military sanctions against Iran. U.S. economic sanctions are administered by the Office of Foreign Assets Control. Currently, the U.S. sanctions against Iran include an embargo on dealings with the country by the U.S., and a ban on selling aircraft and repair parts to Iranian aviation companies.[1]
The United States has imposed sanctions against Iran in response to the Iranian nuclear program and Iranian support for Hezbollah, Hamas, and Palestine Islamic Jihad, that are considered terrorist organizations by the US. Iranian support for the Shi’ite militias in Iraq and the Houthis in the Yemen civil war are also in contention.
It's clearly the rank and file citizens of Iran that suffer, and for that I feel sorry, but ... the decisions of a government or Dictator often cause problems for it's citizens ... ie: being able to trade with other nations, or as an example buy spare parts to repair things. Since the things that were being built in this Video come from China ... is China being blamed as well ?? don't think so.
So, who are you actually mad at, the United States or Iran who caused the problem ??? kinda like being supported by your parents and then doing something that you know they won't like and they find out ... and they cut you off !! Can you be mad at your Parents for not supporting something you knew would cause them to withdraw support ??
I may not like all the decisions that my Government makes, but I don't know all their reasons either, apparently Iran did something that cause the US Government to withdraw support ... has Iran always dealt fairly ??? only you know that answer.
Lets hope our two Nations come to an equitable agreement for Trade !!
