why not zigabee, it was designed for it

this miricle wireless charging isnt to hard to do, its basically just a loop of wire and electromagnetic induction. might be worth it smile.gif

for home automation i thoght it would be easier to have a bridge to a home PC that has the IO

My electric toothbrush works in a similar way. There is a cone coming from the "docking station" on which I put the toothbrush. That cone contains an electromagnet which is driven with AC. In the toothbrush put over the cone there probably is a coil which converts the electromagnetic alternating field into AC again.

This works well for low power and over small distances.

But I don't like the idea of distributing higher voltages for household appliances that way! What happens with your pacemaker? The liquids in the fridge or even in your body may be electrolyzed. etc.
In times when influences of low-power RF in brains are discussed heavily, it will be hard to establish something like that anyway. wink.gif

But back to Wusb: It would need a significant amount of power to charge a phone which is even only a few cm away from the zaurus. My feeling is that this is in no way possible using the Zaurus' battery.
