Tutorial: Get power from your USB-Port for self-built USB gadgets

hello everybody

my first video tutorial today I'll be

showing you how do you get the power

from a USB cable or basically how to get

power from you USB port in order to use

it for your own USB experiments or use

be gadgets for example for a self built

fan of course we need a few things for

this so first of all I'm gonna start off

with what we need first of all we need a

luster terminal or chocolate block this

is not necessary but it will make things

waste easier for us and you can already

see that there's a bit of stuff cut off

but we don't care for that for now then

we will also cause neither scissors like

you can see here we will also need a

cross tip screwdriver for the last

terminal if you will use the last

terminal we will need a led of arm for

testing out may we actually get the

power from the PC and of course we will

also need a USB cable right now here we

can see a USB cable with a USB a and

with a USB B connector we will mainly

need the USB a connector arm so yeah let

me just like cut the package off let me

unbox the cable and then let's just

continue through with the main part of

the tutorial okay so welcome back to my

video tutorial right here you can see

that I just unbox the USB cable what we

will need to do next is basically just

take the cable and cut it through at

whatever position we would like to cut

it through arm so I'm just going to take

the half of the cable in this case and

I'm just gonna cut it off in the middle

so let me just grab the scissor right

now and just come through this won't

need too much power for now so yeah

there we go now you have to search the

end of the USB a plaque of the male USB

a plug and then we will have to de

isolate the cable that basically means I

getting the white plastic stuff around

the cable in it just get it off so we

can access the wires inside the USB

cable better to do this you're just

going to take the scissor which I'm just

grabbing right now and you have to sorta

try to cut only the plastic off this

works waste better if you just turn the

scissors around a few times around the

cable a few times just make sure you

don't in any way arm hurt or damage the

wires inside the cable as soon as you

arm wrap the plastic part off you should

be seeing a few cooper wires on as this

process to actually get the plastic off

takes some time just going to pause the

video once again and I'm just going to

come back to you since we cannot see the

Cooper wire inside the cable so welcome

back for the second time within this

tutorial right here you can now see that

we get the Cooper wires inside arm

inside the cable the Cooper Y is only

the isolation of the aware of the cable

and you can also see that this special

cable is also d isolated with a plastic

sari with a silver foil right here so we

will not need the silver foil on the

Cooper wires so the outer Cooper wise in

anyway so let me just cut the silver

foil and the Cooper wires off gr just

try to get these aside um just try to

get these aside basically and as soon as

we cut off all the Cooper wires you can

see right now that my table is getting a

bit untidy but that doesn't care for now

we will have a better view on the four

cables within the silver foil oh there's

no silver foil in your arm cable that's

not a problem either right now you can

see that we get a green white black and

red wire right here the green and the

armed white wire are basically for the

data transport of the USB cable so for

example for game controllers or so and

then the red and the black wire these

two sorry these two wires sorry again

these two wires are simply for the arm

for the energy so we will not need the

white or the green wire in any way today

because we will not do any USB

controller so we're just gonna try to

basically get

power from USB port to enlighten a LED

so I just cut the two green and white

wires off so I can focus on the black

and on the red wire right here

sorry once again okay so we will also

need to de-ice elate these two Y&T these

two wires um you can see that there's

just waste less plastic around it then

on the standard on the white plastic

stuff so do not actually cut the cable

here just put your scissors around it

just really just do a bit of fresh on

the cable and try to wrap it off with as

less force as possible cause else you

will they're just cut the cable off

because it's just that small okay so on

this process might take some time too

because it gotta be careful to not

actually cut the any of the wires off if

you still cut the wires off then you

will just have to de-ice elate a bit

more of the white cable and get a bit

more of the isolation off okay now we

can see that I just cut off the both of

the isolations so once again we can see

that the red cable this is basically the

+5 volt cables and that the black cable

the black cable is big round cable so

let me just connect this to my USB port

on PC um and right now um yeah let me

just connect this basically to the USB

port okay um you can see that I get a

LED in my hand please never use a LED

without a resistor for a longer period

of time because it will just burn

through right now let's see may we get

power from the USB port so you can see

okay there's basically the wrong way of

the LED yeah so let me just turn it

around and it should get really hot okay

you can see that the LED is enlightening

and it's getting pretty damn hot here um

yeah you can see that the LED is

enlightening if you're going to use any

LED then always use some resistor for

example 120 ohm

even though want just use some resistor

because else the LED is simply going to

burn through okay so um if we want to

come back to the chocolate block or the

lustre terminal you can simply get the

two ends of the chocolate block or you

can actually just put the two wires into

the chocolate block and this will make

it easier to connect for the stuff for

example like any engines or other LEDs

or whatever for example what you need

for self-build USB gadget fan arm we

will of course also need the screwdriver

for the lustre terminal I hope you enjoy

my first video tutorial hope you learned

a bit from this and yeah have fun with

your self-build

USB gadgets
