PSP Portable Power





Introduction: PSP Portable Power

I needed a way of charging my psp at work, I work in earthmoving equipment where 12v is not always available. So I made this up from mashing up various other instructables. Don't try this and blame me when you fry your PSP - always test the final product with a multimeter and ensure the polarity is correct before plugging in your PSP.

Step 1: Get the Goods

Bits you will need......

PSP case
Two old garden solar lights (the two AA flavour)
4 AAA Nimh Batteries
5volt regulator link
Shrink tube
Spare wire
PSP Plug

Step 2: Break Stuff Up

Trash the garden lights remove the solar panels and one of the diodes which look like the image shown. Solder wires onto the solar panels, poke the wires through the lid and mount the panels with glue to the lid.

Step 3: Battery Pack

Make up the battery pack, postive to negative to get your 5v, fold up the foil and use it to bridge the terminals, attach the tape nice and tight to ensure good contacts. I used some 9v plugs to make it easier to remove.

Step 4: Solder On

Wire up the diode and resistor as shown in image, make sure they are the right way around (the current only flows one way) before soldering by testing with a multimeter (I had photos on my laptop but my dog ate them), check voltage with multimeter. Put layers of shrink tube on to stop any wires from breaking. Solder on the plug, test and re-test.

Step 5: Enjoy!

    Your dog ate photos on your laptop? How is that possible?

    what does solder mean

    Seriously (no offense)? It means using a soldering iron to heat up solder (a small tube of metal) and wiring electronic components with it.

    you need a switch for power to the regulator. even if it is not plugged in, the regulator will draw current.

    I was wondering if i can use the nokia batteries that give around 3.6v if i am not mistaken and use it directly. An added feature is that it can be recharged with a Universal Battery Charger

    although quite complicated and crude Very Clever! How much would it cost in total?

    pfft.. i bought solar lights at my local walmart for like 4 bucks a piece.. they are dirt cheap...

    Where would you buy them in Australia?

    any 'big box' store or discount store.. i am in canada so i don't know for sure
