Electric Switch from Receiver?

[Dan]

Anyone ever try to trigger a relay directly from the receiver?

I was hoping for a circuit that would allow me to connect the servo
lead directly to a circuit board and trigger a relay with out using a
servo and switch.

Thanks, Dan

Here is a link to a french circuit :

http://club-contrex.ifrance.com/club-contrex/Commut_01.html

It's a 2 way module you plug to the receiver.
It requires a proportionnal output on your receiver.
Loads are controlled by relays.
Each way can work 2 ways : impulse (load "on" til stick forward) or memory
(stick forward->load on, stick forward again, load off).

Sorry, but I won't have time to translate that page for you. If you know
basics of electronics, you should be able to reproduce it.
All components are easy to find; some schematics are smaller but require PIC
programming...
This circuit is very reliable, too.

Hope that helps.

Here's one that I adapted from a design for a glow plug driver on
Brent's R/C Electronics Page:

I use it to operate solenoid valves that fire pneumatic cannons, but
it can have other uses. Such things can be bought ready-made as well.

Not direct from the receiver, but theres one on the web
that takes the motor lead from the R/C servo board,
adds a capacitor and then ties to the relay. The circuit
only needs one or two parts besides the board from
the servo. If you can't find it, I'll look it up. Old servos
are easy to find these days.

Hobby-lobby.com sells an on/off type of motor speed control that plugs
right into your reciever servo output jack. Might work for you for about
$30.
