This is a (very) simple tutorial to show how to get your VMU alive and working without a dependency on expensive batteries or requiring a heafty 4x AA battery pack or similar.
This simple hack means you power up your VMU with a just a USB port. This does not allow your VMU to interface with your PC or similar, it just acts as a power source.
If anyone else has any similar VMU power-supply ideas, let me know

Its nothing fancy, but it means I can look after my Chao without using up £10's worth of CR2032s...
