Simple 9v usb charger in an Altoids tin

Parts used

Altoids Tin (empty)
5v Voltage regulator-i used a 7805
Female USB port
Wire
Battery clip
Battery

Tools

Soldering Iron
Solder
Drill
A File

Optional

Shrink tubing 
Switch


Note:this is my first instructable please tell me how i did :)

Step 1: 7805 pinning and usb pinning

 on the 7805:

pin 1-positive in
pin 2-negative (ground)
pin 3-positive out



on the usb:
D+/D-      these are data-lines and are not used in my instructable


****EDIT-on the usb the pos and neg are it the wrong spot just flip the position :)

Can it work for galaxy ..??

[James Kenefick]

i used a car charger to usb converter but for some reason it says "charging is not supported with this accessory" what should i do

[frisbeechamp1983]

Could you use 2 9v's? I'll be gone for 10 days, and don't really access to batteries.

[Tanky53]

Do you have to worry about the data transferring wires in the USB? The way i'm thinking is that you only need the power supply wires.

[clzfishing]

Where did you find the female usb port i cannot find one?

[nodoubtman]

i think that doesnt work for a ipod touch 4 G?

thank you!

Does the 5v regulator work for over 9 volts? Could I hook a 12v?

[31mimo]

Yes!

[rryapolov]

Would this schematic work?

[31mimo]

Totally wrong 7805 pinout is 1-input(more than 7V DC) 2- ground 3- output 5V DC

[stratohellsing]

Rryapolov, your 7805 pin usage is wrong.
Left is VOLTAGE IN
Center is GROUND
Right is VOLTAGE OUT (the one with LED should be the RIGHT one).

Cheers

[astrickland1]

no

[joemmm]

does it work for iphone?

[astrickland1]

no

[ugoel]

listen the instructable is amazing as a first 1 but i wud like to know if i cud use dis on my "samsung s5620"

thanks

[PerfectPantaloons]

Genious idea

[dudemanclc]

wow

[PerfectPantaloons]

this completely FRIED my ipad.... I just got a diff transformer to match the input charger levels, and bam a little ozone later and it NEVER WORKS AGAIN!!!

[dudemanclc]

I wrote wow because you spelled genius wrong

[npn-diodes]

Yeah, like Thermiter wrote the picture of the male USB connector confused me totally.
So I changed my text 4 times. lol
You wrote > on the usb the pos and neg are it the wrong spot just flip the position :)
Since you meant the voltage, not the data lines, I think that you mean a female connector, since it will be built in the box, so you show the wrong connector.
But I didn't want to complain since I know from job how much work it is to be 100% correct. So I wanna say thank you. :-)

FYI:
I found the same sites that Thermiter noted.
Please have a look at: http://en.wikipedia.org/wiki/Universal_Serial_Bus#USB_standard_connectors
You already know:
http://pinouts.ru/Slots/USB_pinout.shtml. They say: 1=VCC, 2=D-, 3=D+, 4=GND.
I tried to add the pics from those sites which are most important, but this site doesn't show them in full height and width. If anyone knows how to change this problem, please tell me. ty
This is my first posting. :-)

if you connect 2 9v batteries how long will it charge and will i need cooling

[yellowexample]

 Pretty nice. How much would it charge an iPod?

[Thermiter]

Unfortunately, off a 9v battery, it won't charge for long.  See my above comment.

[Thermiter]

This is a pretty nice instructable.  I made one of these for myself before I read this and I did it a bit differently.  First off, I used 4 x AA batteries because using a 9v only gives you 600 mah or so, AAs give you over 2500.  Also, I used a low-dropout regulator because I knew that the 6v would not be enough for the 7805 (try the LP3873ES-5, it's more complicated to use but worth it).  I'm not sure where you got that female USB, but it's kinda bulky, you could try a different version without the big plastic ears to sleeken the design.  If I were you, I would use a cutoff wheel to cut the rectangular hole for the USB port, because it's a lot less hassle.  Lastly, you should include a link to the instructable on how to force an ipod to charge from 5v DC, because most people want this to charge their iPods, and it won't do that the way you have it configured.  I actually considered writing an instructable on how to make one of these, but if you consider my advice, I won't have to ;)

[Thermiter]

And one more thing I almost forgot.  You should clarify the orientation of the USB pinout.  The picture you have is of a male plug and it's quite confusing.  There's a good explanation here: http://pinouts.ru/Slots/USB_pinout.shtml

Very nice Instructable. Maybe you should add the pinning for the 7805 and the USB-connector because some people are not familiar with those.

[james7193]

 doing it now :) thanks for the tip

[janw]

Yay! Looks great. Super for you first Instructable.

[james7193]
