Remote control of gate, suggestions

Hi guys,

An easier question this time. This place I have recently bought out in
the sticks has a 12v gate opener in one of the sheds. I have tried it
and it seems to work OK, but there is nothing else to go with it.

Anyone now of kits of the following bits??

Key ring transmitter
12v Receiver with relay
Programmable, 10-digit key pad with relay for friends to use.

I have it hooked up with a 12v battery and a small solar trickle
charger, but I have to get out of the car and hold a button down and
that is not the whole idea. <vbg>

I can control the stop on open and close with limit switches to drop
power to the opener.

Any suggestions will be gratefully received.

Mount the button on a post that you can reach from your car window? ;-)

Radio shack has a key-ring remote, but the receiver is 115V. I suppose you
could hack into it and run it from 12V; it's just a receiver and relay.

Good Luck!
Rich

Thanks Rich, I'll check it out.

Buy a wireless doorbell at the hardware store. Hack a relay into the
chime and use it to control the motor. Put the door button on your
keychain. Usually both ends are powered by batteries, so you will
have to change the battery periodically.

Buy a remote door lock kit at an auto parts store or car stereo / car
alarm shop. It will come with a nice keychain transmitter and the
receiver is guaranteed to work on 12 V DC.

Linx http://www.linxtechnologies.com/index.php?section=products&category=oem_products
sells such things, but it will probably cost more than the above
options.

A little harder. The wired kind used to be sold for garage door
openers, but I don't know if they're commonly available anymore.
Most of the links online are for wireless, and it'll be hard to
find a wireless garage door transmitter that matches a wireless
doorbel or a car door lock kit.

You might be able to adapt something that is meant for home
security system use. alt.security.alarms might be a place to ask
about this.

Suggestion: Keep the button, or replace it with a key switch, as a
backup in case the radio link isn't working. You might even rig up
a connector so that +12 V can be supplied from your vehicle in case
there is a problem with the battery.

I can control the stop on open and close with limit switches to drop
power to the opener.

Suggestion 2: If it doesn't already have one, you might consider adding
a circuit breaker (not a fuse) in the motor circuit. This protects the
motor in case a limit switch fails or the gate gets iced shut or stuck
in the mud. Auto parts stores will have 12 V circuit breakers up to
30 A; RV shops will have ones that go higher than that.

Standard disclaimer: I don't get money from any of the companies
mentioned above.
