I was just wondering: Is there any possibility besides modding the controller of teh keyboard and building/using a bluetooth controller to convert a USB-keyboard to bluetooth?

Well, for a while there was Wireless USB but that proved to be a technological disaster so wireless USB dongles never took off.

This was the closest thing I could find.

But it emulates a PRINTER, not a KEYBOARD.

There are some cool PCBs at sparkfun.com. Look at the bluesmirf to get some ideas. It is not remotely trivial from my research.

Been looking into this myself and theres quite a few possibilities if you would like to make serial keyboards work over bluetooth or design a keyboard around a bluetooth module from the start, but 'converting' USB over bluetooth really adds unwanted complexities to the mix especially if you want the device to run out-of-the-box on any system through bt HID.

Wow! Thanks for that link.

I would still prefer a dongle that could convert ANY USB keyboard to Bluetooth.

Im pretty sure such a device does not exist.... Simply because USB is a bit of a resource-hog it would take some serious hardware and batteries to do this. Im not familiar with hasu's HHKBt but my guess is that hes relying on the PS/2 backwards compatibility on the board and is sending that over to the PC. Like i said, something like thats very doable.

Is there any Workshop or HowTo available on how to do such a mod with a PS2 Keyboard?

I think this is very possible, I was able to find this: http://www.aten.com/products/productIte ... l_no=cs533

and this: [youtube]http://www.youtube.com/watch?v=RTEKN1UO8cc[/youtube]

I'm actually thinking/planning on building something that could possibly do it. I've already ordered my first component to just experiment with. I'm building it using an Ardruino Uno, and if that's successful, I would love to go even smaller and embed it into a nice case of some sort (most likely going to have to build this custom).

Great link!
Looks like we have just what we're looking for. Once you open it up and fit the business end inside your keyboard.

$59 each plus $14 for non-US shipping. But 25% off if you link an article you've written about the device? Wouldn't mind exploiting that for a group buy. I could use a few after my first!
