How to : Convert Nintendo Wii Sensor Bar to USB Sensor Bar

[DuoDynamo]

First of all, thanks for the tutorial.

Is there a way to convert a 10 LED bar to USB without the use of soldering iron and batteries? I heard this is possible if you have a 6 LED bar since it consumes less energy, but my model is a 10 LED one and I don't have the necessary equipment to do soldering work.

I suppose simply removing the extra LEDs isn't going to work; or is it?
