DIY - USB Load Tester

[@jimmygerilius8494]

I've never seen someone use a soldering gun the way you do, and make it look so simple. I remember having and using a soldering gun some 40 yrs ago, and burning insulation as i would try to solder/splice wires. And yet you solder @5:36 with ease and skill. Outstanding job for doing this with what you have. Someone once asked me "What's the best knife to carry and use", and I would answer..."The one you have with you, is the best one to use". :) Nice job on the DIY, and editing of these videos that you make, and your sense of humor works perfect! Thanks, JimmyG

[@kushalbhaskar4401]

Your videos are always an amazing experience to watch..... so much hold, so much funda on the subject...OMG...

[@gabrielantiligando9905]

Yeah your actually Very good in electronics. I learned alot from ur prev video!

[@thebookofwhitewalkers4610]

great video. For easier work you need a more precise soldering device. Try a mini TS100 and a Daniu PX988.

[@DrZipZwan]

Hello, amazing video as always!! So well explained and there are always stuffs to learn as in all of your vids ;) I will realise this tester, but not sure when, lol Btw, I learned a great info, always use thick cables, for phone charging and other stuffs, now I get why fast charging of my phone is not working as supposed! I did like you, throw away cheap testing cables, and created my own cables with thick wires :) only minus is, there are less flexible, but who cares, they gives good measurements!! Keep the great work ;)

[@diegorambo2569]

Nice Sorin. It would be awesome if this USB test loader could measure the capcity of an powerbank in maH..

[@AmitGupta-tt9ky]

Which soldering iron you use can you please make video on DIY soldering iron

[@davidmarkwood7314]

Defo making one. Just found your Chanel and loving it. thanks for your time and keep up the good work

[@ionpopescu111]

Sorine, salutare. Sper că ești bine și sănătos. Mulțumesc pentru postările tale foarte utile și instructive. Ași vrea să te întreb, dacă am doar un voltmetru de cel cu două fire groase, cum să unesc cablul cel galben din schema ta?

[@Sorin_DIY]

Salut. Daca ai voltmetru cu 2 fire groase, se conecteaza altfel. firul galben al voltmetrului (sense wire) se conecteaza in locul firului rosu gros din schema.

[@stevenA44]

I've been wanting one of these so I might just make this. Thanks.

[@etow8034]

A lot of work for something that you can buy off the shelf for under $8.00usd. If anyone needs a good USB load tester get the RuiDeng LD25/LD35 that measures up to 5A and 7A or HD25/HD35 that has the built in QC 2.0, 3.0 trigger.

[@Aslan1666]

Nice job. Can i use potentiometer instead of those power resistors to achive different resistance to check 19 volt or 24 volts?

[@Sorin_DIY]

no. potentiometers can't handle 1A.

[@owenmcpro]

Nice, I was looking for something like this, I'm gonna make it to test my 18650 batteries

[@electronic7979]

Excellent video.it was useful to me.thank you so much.

[@GregOnSummit]

what did you do to enable fast charging?

[@Sorin_DIY]

I added the data wires between the input and the output.

[@Newb1eYou_]

i might make that next month thank you sorin!!

[@MyHaY112Gameplay]

Salut , sper că ești român! Ador videourile tale, keep up the good work man!

[@omkharde2325]

Can u please provide circuit diagram for this

[@Sorin_DIY]

hi. I've added the schematic in the video description.

[@tmburns4]

Awesome video! Complete beginner here, trying to decode your schematic: is there really nothing attached to the negative lead of the voltage meter? Or is that the current meter? My voltage meter has three wires for the voltage and two thick wires for current.

[@Sorin_DIY]

hi. the thin black wire is for powering the volt/ammeter. but if you power the volt/ammeter from the same source that you measure, you don't need to connect both black wires. the volt/ammeter will take the supply negative from the thick black wire. but if you supply the voltmeter from a different source than the one you measure, then you connect both black wires. the thin one to the voltmeter supply voltage and the thick one to the voltage you want to measure.

[@CrazyCoupleDIY]

You are a gem

[@-bru-NO]

Loving your videos. You should buy a proper soldering iron and use flux or rosin core tin!

[@neutronpcxt372]

It is a proper soldering iron. Look at the chain comments up there. Edit: Never said it was appropriate though.

[@-bru-NO]

You have little to no experience soldering SMD or small TH components, do you? that's not a proper soldering iron. Not much to explain, really, even though he likes it, he can do 100 times better with a proper pencil-like iron and good flux, I guarantee you. No need to go for Weller or Hakko irons, i'm not an etilist, but that gun iron... ughhhh

[@neutronpcxt372]

I do have experience THT soldering. It is a pain in the ass with a big tip. I personally have a TS100 and a Daniu PX988, and they are so good for the money. I never said his soldering iron was adequate for the job though. I'm just saying it is one, a Russian one too haha.

[@turkeyphant]

Can you use this to test pd power supplies?

[@Sorin_DIY]

yes

[@njfulwider5]

Neat little load tester and a GREAT Idea!!(New Subscriber here!!!)

[@annrezarcade7985]

what was the tolerance resistance of your 4.7ohms load resistor?

[@Sorin_DIY]

I don't remember the tolerance, but the resistance was very close to its nominal value.

[@AndreaArturoGiuseppeGrossi]

Great videos!! I love them! Also because you put math & good geeky science in it! Yeah! :-D

[@johnnynethanel3142]

Could the resistor 10w 5ohm change with 10w 10ohm?

[@Sorin_DIY]

yes but it will draw 0.5A

[@johnnynethanel3142]

@@Sorin_DIY How 'bout 5w 10 ohm?

[@Sorin_DIY]

at 5W the resistor will be very hot.

[@navisb8345]

Super thanks brother

[@db6178-jm]

Sorin, you're funny :)

[@earumamaadu]

How to connect data wires and where to connect? I don't understand

[@Sorin_DIY]

the data wires are just 2 simple wires, connected from the 2 data pins (middle pins) of the USB connector, to the 2 middle pins of the USB port. they act just like an extension for the data pins, from the USB connector to the USB port.

[@imtaufiqmehedi]

Which one can i use, 20w 100 ohm or 20w 4.7 ohm???

[@keithking1985]

Use the 20watt 4.7omh the other resistors are limiting the led current!! that's all.

[@keithking1985]

But 5volts over 5ish omh's is round 1amp. If there is a switch that can make them parallel you will get 2amp's load. Very handy👌

[@keithking1985]

That was a great video. Very clear instructions. I'm going to make this load I already have the parts. I think I'll subscribe too.. this isn't the first cool video if seen of yours.👏👍👍

[@francescotiboni397]

Awesome project

[@frenchcreekvalley]

Nice job!

[@neutronpcxt372]

First off, are you French by any means? Because your accent makes it seem like so. Also, did you build your own soldering iron? Seems quite powerful.

[@MkwRa]

he is romanian

[@neutronpcxt372]

Thank you for the answer.

[@Sorin_DIY]

hi. I use an old soldering gun from the '90. it's Russian made. I like it because it's very powerful and efficient.

[@johanponin1360]

doesn't sound like french accent at all

Baaaa de cand e ciocanul ala de lipit??

[@Sorin_DIY]

din anii '90. de ce? pentru ca e cel mai bun. a fost cumparat "de la rusi".
