[sdiy] semi-OT - RF or IR link

[Toby Paddock]

Any ideas for a SIMPLE and CHEAP transmitter/receiver to make a wireless 
controller? I'd like to get rid of the umbilical cord on my triaxial 
accelerometer. It would be more fun to wave around without the dangling cable. 
(Next time I'll use the ADXL202 that Harry mentioned because it has analog and  
PWM outputs. PWM might be easier to go wireless.)

I think it would be handy as a generic controller interface, like for a ribbon, 
hall sensor, photosensor, bendy shoe sensor, hand capacitance sensor, pressure 
sensor, breath controller, knob & switch box, or even analog keyboard if it was 
accurate enough.

As a minimum to start with...
3 analog 0-5v channels, 0-20Hz or so
1 digital channel for a gate switch
10 foot range, not line of sight, but not outdoors
stand-alone, no pc

Maybe ignore the cool ID code stuff that would allow more than one to be used 
at once. At least to start.

http://www.futurlec.com/Radio.shtml If I was smarter, I'd convert it to serial 
data and try these. 

It just seems like there should be something to make it easy, with all the 
wireless sensor / wireless mouse / bluetooth / wireless everything / robotics 
stuff that's going on.

Thanks,
