Radio contol but NOT of models

The cheap solution is a pair of walkie-talkies & a volunteer to be the remote "control system" ;-)

I think, Tony, that we really need to cut out the human volunteer bits of the system as it is! They are the biggest problem and the weakest link! Especially as the in-house system has an 8-way mixer with lots of knobs, bells and whistles for every tom, dick and harry to fiddle with, particularly those not of our group.

I want to cut it all down to just one house input, with presets on it that I can remember, and control everything from wherever I am in the main room, without wires. Having a radio mic, a stick mic, a vcr/dvd player and a video projector is enough without the house system's variables!

p.s. just imagine - up a bit on four - NO FOUR - no thats too much and its on THREE - a sh*t, thats deafened everyone and the amp has blown it fuse - goodnight all.........

The cheapest solution, if you don't need a long range, would be to use a TV Infra Red remote. You can purchase (or build) a little module that will receive and decode the IR signal. Regards, Allen

Dave,

Lots of ways of doing this all with their (dis)advantages including

Hi Dave

I routinely use PICs to interface from R/C outputs to various things e.g stepper motors, lamps etc, it's fairly easy to do.

As you know R/C outputs vary the pulse width from 1 to 2 milliseconds, the PIC converts this into a number between 100 to 200, then a program can do what you want to it, in this case alter the pulse width on an output to feed a resistor/capacitor to give a varying voltage which could be used to vary the input to your FET or Transistor.

Excuse my ignorance, what does the BSMEE stand for?

Bristol Society of Model and Experimental Engineers I suspect !

You suspect well :)
