altoids PSP recharger

Step 3 Assemble the circuit

once the battery pack is installed and the glue has dried you can break out the soldering iron. It uses a extremely simple circuit and I should be able to discribe it, If you have trouble understanding or I just do a bad job of discribing it and the sketch doesn't help, just tell me and I can go more in depth. Here I go.

The output plug and the LED are wired in parallel (if they are in series, the LED will suck up too much voltage, I learned that the hard way) through the switch and the regulator, Just look at the sketch please

once you're done with soldering make sure there is no way that it will short because the whole thing will be crammed into a pretty small space in the end

ONWARD!!!

i followed all the directions and everything but i am geting no charge out of the jack

if the orange light isn't lighting up on the PSP it probably is charging, but like he said, it is a bit under power.

yea i agree because i heard green leds take less power to light than other colors like orange wjite and blue

that really does not make any sense cause it probably has a circuit that lights a orange led when charging the battery. you need a certain voltage or it wont go. i learned this with a little thing i made up for this. it was a salvaged 4 battery pack. i just snipped a usb charger cord and soldered the wires on the pack. when the batteries started to die, they where putting out less voltage(what happends typically when aa's "die" ) they got below the 5V minimum and it stopped charging. i checked it with a multimeter too. btw, you really dont need to put any kind of resistor on the batteries because 6V isnt really going to hurt it that bad, if you need a longer charge, just go with c or d batteries(both 1.5 volts, just more power)

Yo same here but i used usb instaed of jack

[polo99a9]

me either...

[polo99a9]

no charge in the psp. is it because the regulator that you posted gives out 5V and only 1000mA? didn;t it need 2000mA? just asking.

[awang8]

Umm... Actually it needs 500mA (max) so the reason it didn't charge is because your battery's toast.

[polo99a9]

I don't think that my battery wore bad, because they wore brand new, and i even recharged them. the reason that i said that it needs 2000mA is because of the original psp charger, witch puts out exactly 5v and 200mA.

I was talking about your PSP battery... Anyway i'm more used to MintyBoost style things now...

[xonsniper4]

Why do you need to have a DPDT switch

[awang8]

A toggle switch/rocket switch would be fine I guess...

[466267]

Hey My soldering iron sucks because the tip is broken so how can i solder small metal such as on the switch button etc.?

Get a new tip?

Im confused about this part The output plug and the LED are wired in parallel (if they are in series, the LED will suck up too much voltage, I learned that the hard way) through the switch and the regulator,
