Step 1: Procure components
1- altiods tin (flavor of your choice)
2- a +5 volt regulatora +5 volt regulator (what this whole project revolves around)
3- a dpdt switch or your choice (it should be pretty small)
4- a four AA battery holdera four AA battery holder
5- a LED for indicatora LED for indicator
6- a DC power connectora DC power connector (plugs into PSP)
7- mono phone plugmono phone plug
8- mono phone jackmono phone jack
9- 2 conducter speaker wire
10- various wires for connections
once you have that you're ready to go!
Step 2: Hack battery holder
once it's cut, go ahead and dry fit it, put it in, insert the batteries and push it as far to one end of the tin as you can then super glue it in
note on super glue: when using teh uberglue don't close the tin until it is completely dry or you will end up with the fumes drying onto the walls and you get the cloudy look that are in my pics, and also only glue in well ventilated areas so that you don't die
There I said it Now you can't sue me
Step 3: Assemble the circuit
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
Step 4: Make the connection and go for a spin!
cut a legth of your speaker wire (it doesn't really matter how long) and attach the two different plugs to each end make sure that the polarities work, the inside of the power connector needs to be positive and the outside negative.(I am not responsible for any fried PSPs, OK)
now, that you have the cord, make it look good, take it for a spin! this was featured in a recent MAKE: podcast but if you missed it, here's how,
Put one end of the cord in the chuck of your drill, hold the other end and let 'er rip, when you're done spin it backwards a little ways so that it doesn't coil up.
