Is connecting a red and black wire really a hack?

its handy to know the basics are covered, keep it up guys

seriously? we go from building a couple of robots that’ll do it like…. robots to cutting two wires and soldering them on. i think this should’ve been put on a hackaday links because it can be helpful, but you know someone had a choice between this and a “serious” hack

“It’s a fairly simple hack, but a useful one.”
The fact that this isn’t a horny robot is not lost on Vince.

I have a question, though–what about the voltages? I’m not the sort that messes with electronics at all, but I do know that if the power levels for the USB-out and the PSP-in are different that it could cause problems. I’ve had both a discman and a bass amp fried by my brother and his idiot friends plugging stuff into them that weren’t meant to be (a different voltage-rated AC power plug and a CD player into the input of the amp, respectively). I assume this does work, but how do you know it won’t kill your hideously expensive PSP? Just curious.

It’s a useful hack. Not every hack is going to involve putting linux on something!

I would say though, that the picture looks like it was taken by Roger Patterson (Bigfoot reference).

For it to be USB it has to adhere to the standard, which states that the voltage levels are 5V at up to 500mA(?).

car 12v to psp 5v ???

Posted at 4:19 am on Apr 11th, 2005 by lei

guys. The output for the car charger is five volts and the usb connection is fine.

I know, the camera is shoddy. This is what I get for purchasing a cheap webcam to use. I’d get new pics very soon, my buddy has snatched the cable away before I could get a “good” shot of it.

I’ve tested this on a old cd player I had lying around. It works perfectly. =)

you don’t really need a 5v car charger to do this. all you need is a spare usb cable and the terminal that plugs into the psp supplying the 5v. You can get this at radioshack for about 2 bucks.

He doesn’t use the circuit in the 12v –> 5v car charger anyway. it wouldn’t make sense.

So why buy the $15 car charger when you can do without it?

Posted at 11:46 am on Apr 11th, 2005 by Eric

This is useful if you have a spare usb cable and adapter cable lying around.

If you don’t, might as well buy a REAL usb cable charger for the psp. $15.

for eric:
so what your comment is “we don’t need additional circuit to transform the voltage or protect our psp”, it’s unecessary to waste the money… right?

thanks for your opinion.

Would a motorola razr car charger work? the phone uses a usb plug to charge it.

Posted at 9:25 pm on Apr 14th, 2005 by max

The USB voltage is correct (5v) for the PSP, but I just looked at my AC charger, and it’s rated 5VDC @ 2A …. 2amps… USB can only supply 500mA.. So you plug that sucker in and you then dont have a computer because it fried the 5V rail. Sorry, no sale. Word of advice, go buy the right one. Don’t make this piece of junk.

Posted at 4:28 am on Apr 17th, 2005 by Matt

This just saved my butt.
How would I have been able to put off going to bed without a psp power supply?
thnx, keep it up.

Posted at 3:26 am on May 31st, 2005 by collinmel

hey one question how can i adapt a usb connection to charger a nokia cellphone, i have tried the same thing u have listed but i have had no luck, i got the LT to turn off once, and the phone just beeps and five seconds later it says “not charging” i have tried to disconnect some wires, but no luck. i would apriciate any advice to keep me going, i don’t want to give up and just order one, so any help will be good.

Posted at 7:07 pm on Jul 12th, 2005 by rul

i have a cd player charger that fits into the psp socket, but it’s 6v. would it still matter even though the psp is 5v?

Posted at 12:24 pm on Jul 22nd, 2005 by takumi

matt is right.

for this to really work without destroying anything expensive, you need a 5V@500mA to 5V@2A transformer. It might be expensive and it’ll be a real hassle to find one, but the coolness factor might be worth it.

btw: the psp should have a REAL usb port so that you could charge it with that. i’ve forgotten the name of it, but it’s the kind you use for printers and scanners. The one that they sell you is hackish.

Posted at 1:32 am on Aug 7th, 2005 by has_hacked_chargers_before

Some of the comments for this hack show exactly why it’s needed – i.e. people have NO IDEA when it comes to power.

The car charger is rated to 2A, the USB port to 500mA. All that will happen is that the PSP could possibly draw more than the USBs 500mA – at which point the PSP may start questioning the the power supply, turn off, or give a warning. You can’t fry the motherboard.

Just because something is ‘rated’ at a certain amperage, doesn’t mean it will draw that full capacit 100% of the time. Do you think you brand new shiny power supply rated at 450W is upplying that much to the motherboard the whole time? No – it probably won’t reach that at any time. if you load up your computer with as many accessories as possible, and ask it to perform multiple task you might come close for short bursts, but not continuously.

Hey i made a charger-usp plug all in one….. i took the charger plug and connected the black and red wires together then i took the usb and connected the red and black to the charger and the male usb….. then connected the green and white wires together….works fine…great ideia…..thanks hack a day……i tested it on my mp3 player (philips micro audio jukebox) and it works perfect! i am sooo happy….

Posted at 4:52 pm on Sep 27th, 2005 by jonathan

what are you talking about?

btw i am trying to make a battery pack inside of a N64 game. If i use 6v of AA batteries (4) and a 1000k resistor shouldn’t it work? Please email me @ souldierofwar@gmail.com

Posted at 1:22 pm on Oct 30th, 2005 by dave

the usb wire has a red green black andwhite wires and charges wire doesnt so its not working

Posted at 10:31 pm on Dec 26th, 2005 by nate

it works on my psp

Posted at 11:13 pm on Dec 26th, 2005 by nate

why dont u just hook up a 9 volt battery to the car charger using headphone wires .. that way u dont have to hack off the end and can still charge it even without having a usb port around … and btw some digital cable boxes have usb ports which are also good for charging

Posted at 2:22 am on Dec 30th, 2005 by andrew

I am putting a 5.2v car charger from an old cell phone to use as a charger. It output 5.2v, ~900mah (roughly) will the >5v fry my psp?

Posted at 8:14 pm on Mar 30th, 2006 by DartH_Poo

Thank you for the idea. Well I didn’t use a usb cable, I used 2 chargers. One was a jvc adapter. I used the plug that connects to my psp. then i used a model cnr-4000 ac adapter. I used the plug that connects to the wall. it output dc5v. I cut both cables in half, and reconected the 2 I needed. I was afraid it was going to blow my psp. But guess what? it worked, and i’ve been using it for about 2 weeks now with no problem. If you need pix, email me hexagram85@sbcglobal.net so I can prove it to you.

Cheesie

Posted at 2:57 pm on Apr 2nd, 2007 by cheesie

oh and where can i find a 5.2 volt in car charger to do it?

Posted at 2:59 pm on Apr 2nd, 2007 by cheesie

You only need the plug and cord from the car charger..
You can also do mobile charger with 4 AA chargeable batteries and then solder a usb connector to em ect..

Posted at 10:43 am on May 3rd, 2007 by asdasdasd

what happens if the plug which goes into the ciggy socket is the problem?
i have the cord and the adapter…please help.

i made this and my psp just switches off?

Posted at 10:07 am on Jul 28th, 2007 by aero9

it will only fry the rail if you conect the green and white cables together my advice is that when you make this mod cut the green and white cables off so your olny left with a red and black cabe which makes more sense really if u think about it…!!!!!

ps oh by the way it frys because the green and white cables shoundnt touch or it will short circuit and fry ur usb rail compleatly hope i help…..

it did not work with my psp

Posted at 10:42 am on Dec 1st, 2007 by psp man

what should i do with the white and green wire email me at gadgetman94@hotmail.com thank for your help

Posted at 10:47 am on Dec 1st, 2007 by Aaron

Guis, first excuse if my english is not so good, second, use this with no fear, the output of the PSP AC Adapter is corect 2000mAh/2Ah, that means that the battery will charge faster and nothing else, actualy the USB Charger is safer because it does not have the power (Amperrage per Hour) to stress the battery pack, so in the end the USB Charger (Homemade or not) is better for Battery Life (Charge Cicles) than the Sony AC Adapter, ask any electronist and it will tel you the same thing, A BATTERY LIVES LONGER WHEN IS CHARGED SLOWLY, keep it up, USE HOME MADE THINGS :P.
