Build Your Own Portable USB Battery Pack - SYSTM

[hj576]

i hope i get a quick answer since i need this for my project thats due this weekend

About the first procedure ! like it supplies power via the usb port. but to like charge the battery . Do we just connect it to a 5 volt DC supply like a USB port of computer or laptop ? will that charge the the batteries or we need some oter way to charge the batteries ??

PLZ CAN SOME ONE ANSWER ASAP

I have a computer FAN . its 12V DC with 0.34 A power.if i connect it to this will it run slow or not run at all

[reaper00020]

Screw godaddy!

[moochie80]

u neve showed us how the 9v worked with the voltage regulator damn ...so does it wok with a 9v

[scientificzhon]

@moochie80 voltage regulator works from 5 to 35 v

[clockrdell]

The first method would work better if you used 4xRechargeable AA batteries (typicaly 1.25v per cell at around 40-60%). The second method will get hotter if you use a 9v battery as it has to drop down a higher voltage, and iPods and the like draw around 0.5A (500mah) so a heatsink should be used on the back of the 7805; furthermore the 7805 requires a MINIMUM of 7v input, as per the datasheet specs, only fully charged alkalines work because they are around 1.6-1.7v per cell.

[Tedlasman]

Where r the links? Can I use a 52000 mah lipo battery pack 3.7V with the step up regulator? Who sells the regulator?

[EastCoastJew]

11:02 to cut through all the talking

[conijoo]

"black and red and nigger "

[sonicandvideos]

hi there how about you make a video about breaking a usb car charger and taking it and ataching a 9 volts battery and on the other side the female usb thanks if you do send it to me

[goldenjamesy]

lol i cant believe this guy drops the N bomb at 13:10,.. so casual

[torontoraps8]

lmao i doubt they'll let you take that on a plane..

[Trev811]

great info but still i have to say fuck you cracker you racised basterd

[padly88]

nice idea, i used mp4 build in rechargable li-ion battery, i took it out from mp4 and solder nokia power connector and female usb connector, i get clean 5 volts and i can use it charging sony ericsson phone for about 6 hours! and i can charge usb charger itself with nokia charger :D

[Playswithhimself]

His scenarios are so stupidly specific, it makes me wonder if he has run into these problems. Like powering a snowman sculpture or being stuck at a bar and need to charge your phone.

[junglejim0n360]

why is he showing us how to do it and not telling us what we need

[d4n2y1]

Wich one works with the iPod touch

[irobot2k]

Yak Yak Yak, someone needs a good editor.....good vid though...

[Iph0neAppReviews]

32 minutes WTF!!

[asif3233]

how to fuck ur self?

[jedrickbaek]

I was using 4 NIMH(1.2volts) battery and using the 5 volts regulator.. why it isn't functioning?.. is it because it has low voltage?..

[TheN64Player]

im a bit confused right now

[Gevoreg]

cool jacket hhahahahah

[ce3jay]

If you use 4 Alkaline batteries, total voltage is 6 volts. Best bet is to go with 4 NiMH batteries with a total of 4.8 volts

[mllmTECH]

does the first 1 work with ipod touch 2g ?

[mllmTECH]

skip 2 10:57 to skip talking lol

[xmodmodifier]

BOO LOTS OF TALKING

[travhal]

hahaha he said nigger instead of negative at 13:07

[10andrenieri]

How many days you spent to upload this 32 min video?

[irelands01]

this vid is crap. took ages for you to stop talking and most people wouldn't understand what you are saying - heat shrink tubing and twisted pairs aren't things everyone knows about.

[80sbreaker]

too much fucking talking before any action interesting subject but boring discription

[ckgilligan]

Would a 5.1V Zener diode work in place of a 5v regulator for project 2?

[ogicabp4u]

Everyday people don't know what 'heat shrink' is unless they are an electrician/hobbist. Neither do they know what 'twisted pair' means.

You HAVE TO explain this to reach the audience you are aiming for!

This tutorial is useless unless you already 'know' enough electronics to do this anyway!

[NadTheBat]

@ogicabp4u heat shrink is actually pretty self-explanatory, it srhinks when there is heat

[ogicabp4u]

1. I can't see what you have done against your sweater.

2. It's too small, you need a zoom on that camera.

3. You go on and on about tips and tips much more than explaining the basis of what your doing!

4. Where are the circuit diagrams???

5. On the second project I cant make head or tail of it because I can't see it. How many wires and to where????

Uhh! you need to learn to explain things better.

[zerocks88]

at 13:10  he says nigger by accident

[david96888]

lol yea he says the black and the red are your positive and nigger--negative power cables

[kenl92]

@zerocks88 ya i noticed that too

[irelands01]

@zerocks88 hahahha

[Armaangandevia1]

@zerocks88 lol ya

[koopa315]

@zerocks88 ROFL ROFL LOL thats probaly what he was thinking about

[Playswithhimself]

@zerocks88 yeah, he was talking about the black wire too, what a racist.

[m0terb0nd]

Thanks

[humxa24]

he did not check it with a 9volt in da vid

[humxa24]

i built da second 1 n workin just f9

[shiftctrlhack]

it took 11 minutes of hearing u talk before you even started to show us how to make a usb charger, stop talking so much.

[TechTalkTips]

Their both in sweaters lol

[kylemproductions]

lol... the guy in the sweater is gay

[stephberg]

Both the iphone and the ipod touch need to see voitage on the data pins to charge. Needs to see approx 2.5 volts. with a couple resistors, you could make both the first and second option work, the other ipods do not need this.

[bangity]

man.. can you like show the regulator wiring part closer? This sucks. I don't know which one go to which one

[MLGsharp900]

DOES ANYONE KNOW:

if you use rechargeable NiMH batteries, which are rated at 1.2 volts, can you just use 4 of those with the first type of charger (and maybe throw in a regulator for safety)?

[green929392]

Good But The Guy said N-'i'g'g'e'-r at

13:00 - 13:15

[calibration20]

Yeah positive and nigger

[TheTubbyKid]

Systm,

I Built This and added an LED and A toggle Switch and it worked for a few hours. but Then it wouldnt charge but the light still came on i pulled it part and resoldered iit but still didnt work so i got a voltage meter and 6 volts entered the regulater and nothing came out the output Please help TheTubbyKid

[toastr12]

So will thos work with the iPod touch?

[si1entscorn]

build one and find out numbnuts

[toastr12]

So will it work for iPod touch

[jesperolsen]

Magic! it's charging it! haha

[planbskater478]

what would happen if i used two batteries instead of 3 would it just charge slower and plus would that work for a 30GB i-pod video

[videoviewediter]

which should i use for psp?

[dhcpy]

what's more efficient? the second or the third one? In terms of battery usage.

I mean, in the second, you're using more bateries, say 4 (1.5V*4=6V) and downgrading with the 7805. On the third device you use only 2 bat and upload the voltage with and (also power consuming) IC.

isn't the 2nd device better??

[randomstufdude]

idk but do u any battery just conneted through a 7805 voltage regulator

[Jedum]

and you're not gonna show us how to make the third one?...I mean, making that board and stuff?...

[Jedum]

Uh, ya but where can I get a little pack for three batteries?...I've gotten them from like little remote controlled cars but can I buy them somewhere?...

[TheSeize102]

this was very awesome, im making this ASAP!!!

thanks!! :D

[jamoramajam]

For the sake of scientific accuracy: Current, symbol I, measured in amps symbol A

Electromotive force, symbol E, measured in volts symbol V Resistance, symbol R, measured in ohms symbol omega

[37474748]

good video did an battery box last week :)

[CharlieBurke]

THIRD!!!!

[powshorty302]

THATS CRAZY!!!!

[powshorty302]

FIRST!
