[PD] [PD-announce] cheap AVR/HID sensor board

[Rua Haszard Morris]

[Correct me if I'm wrong, I'm not too sure about this but] I think the USB-HID device is a lot faster/more responsive than the USB-serial interface used on Arduino. The advantage I see is that it's cheap, easy to build/understand, relatively responsive, and the you don't have to write or get a driver as it's a class compliant USB-joystick (i.e. semi-reliable folks like MS, Apple, linux do that for you). Though you do need to be able to interface with a joystick at software, but PD can do that with [hid] (?), and I believe there are other software utils to convert joystick motion to MIDI (aseqjoy ?).

That's my limited understanding.. I haven't built mine yet :)

have fun
Rua HM.

I think Martin made this because he thought the Arduino was a bit 
overkill. It does seem a bit funny to convert a EUR 30 board into 
something that a EUR 5 board can do ;-)

The circuit diagram is pretty simple, if you can't etch it I think you 
could still build it in an afternoon.
