Multi Purpose Usb Lead

Ok I thought it was time to have a new hardware project.
I've just started to use giz remote so I can control my Gizmondo from my pc and I'm finding my battery runs out just as I'm doing something interesting and I'm having to reach for my external battery pack to keep things going.

Now the ideal thing would be to have the Gizmondo charging from the same usb output as it is connected for active sync. One lead for both jobs.

Now I must stress at this point that I have stated in the past that It was not a good idea to charge the gizmondo from a USB port because a fully discharged Gizmondo needs 0.6A whereas the USB standard is 0.5A. This is true so I am only advocating using this lead to keep a charged or partially charged Gizmondo topped up. Most modern USB ports will shut down safely if more than 0.5A is taken. If this happens to you, unplug the Gizmondo and charge it using your wall adapter for a while before plugging it back into the usb.

Ok that said, here's what you need:

1 x USB lead with standard USB A plug on one end and mini B usb plug on the other.
1 x maplin dc jack 3mm x 1mm power plug part number AQ86T (£0.79)
1 x maplin dc power adaptor lead part number AQ81 (£1.29)
1 x soldering iron and solder
1 x blunt knife

There's two ways you can do this. You can cut and resplice the cables together or if you're careful you can strip and expose the cables without cutting which is what I shall describe here.

Take the USB lead and strip out a 2cm piece of insulation about 20cm away from the mini B end. I advise using a blunt knife for this so you don't cut into the inner wires.

Next strip a small piece of insulation out of the red and black wires and tin with solder. I melted mine off with the iron.

Next take the dc power adaptor lead and cut, strip and tin it to a length of about 20cm.

Now solder the white stripe wire of the dc power adaptor lead to the red usb wire and solder the black only wire of the dc power adaptor lead to the black usb wire.

Insulate both connections with insulation tape and then wrap a few turns of tape round to finish off neatly.
