Hello,
I've got one day off work and started looking for some charging dock for my Touch. After some searching on internet I figured out to do this from Lego.
I've made it in about 2h. It's working, I'ts using normal USB cable so I can connect it to PC or to charger . I used black and red to match my mouse and mousepad colors.
If you would like I can dissasembe it and make some instructions how to build one.
