I think bluetooth2 and 802.11a/b/g/n are, at the moment, the best standards to shoot for. I was reading that various companies in the entertainment industry don't like usb-uwb and wireless-hidef-video and are talking about boycotting them.

I saw that Intel have a new mini-pcie 802.11b/g/n adaptor out, so perhaps a mini-pcie slot gives the greatest flexility.

That's the great thing about standards is there's so many to choose from!

It sounds funny but apparently scientists are already talking about ways to power devices wirelessly. RFID's are a modern example of doing it.
Come to think of, adding a firecracker serial device inside the pocket penguin wouldn't take up much room. Then you could control your house wirelessly without getting off the couch. smile.gif Not sure how many people are into X10 though.

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.

wireless charging? it's been done, by a Cambridge company, who unfortunately seem to have screwed up negotiating with the PDA and mobile phone companies to get this widely adopted.

google for "splashpower".

zigbee is a slow version of bluetooth designed for automation and not bandwidth, better for lowest power devices. nokia have their own version too now.

someone's going to suggest implanting an Iridium satellite phone module next, I just know it!

actually its nothing new at all, i have seen a project from 10 years ago for a model rocket that had a battery and accelerometer in a sealed unit that was charged with this prinicple

actually about that satalight module, there are some tricky things in there and the full implications havent yet been revealed or explored smile.gif

personally i am waiting for the 1 shot ion cannon upgrade before i buy one oyf these things wink.gif

yeah the zigabee is nice, but i am saying if you have bluetooth you may as well just connect to your house over bluetooth and or wifi and connect to the home controller then send commands (http, ssh, some hacked up shell script with nc)

just because not everything in you home will be zigabee connected so you might as well just make it a service on the network and use the home controller as a "protocal routor" at layer 7

just a side note, wireless usb does in no way provide power, it is a comm protocal only

Sure. I think Drake01 meant this as a joke because many phones are recharged over USB.
But an interesting topic anyway.

You got it! I had meant it as a joke and I'm surprised by how much semi-serious discussion was generated. But I suppose I should have expected that with this group. wink.gif
