simple wireless transmitter and reciever to call an elevator

I live in a high rise building that is about 30 years old. Unfortunately the 2 elevators which service my floor are completely retarded and seem to be completely un aware of each other as they sometimes will both open when called or not stop on floors or other obscure behavior.

In general this is not too big of a problem since eventually they do come to my floor and take me where i need to go. During peak travel times, however, I can wait for the elevator to get to my floor (out of

20) for as long as 5 minutes before it gets there.

knowing this, i have even gone in the hallway, pressed the button, gone back inside, brushed my teeth, come back out, wait a minute and finally see it arrive.

being somewhat technically savvy and in need of a fun project- i would like to install a simple receiver inside the button panel in the hallway and have a small fob in the apt. ideally, i want to be able to "press" either the up or the down button from my apt so that i can call the elevator in advance before i get to the panel. i don't have too much interference- perhaps 40 feet max with 4 walls in between.

i have never done any wireless projects but envision a simple 2-button transmitter and a receiver which will momentarily short the same circuit that the button does when it is pressed. in a perfect world, the receiver would be powered by some circuitry already in the panel and the fob would be like a car alarm fob or a garage door opener type of transmitter.

Any help (including parts i actually would need [with weblinks]) is much appreciated.

Well, how about walking down the stairs?

Healthier and faster...

Not if you can't climb the stairs. Not everyone is in good health and has two good legs.

You are looking for a high tech solution to a simple problem.

Here is a better idea:

Push the elevator button and lean a broom against the elevator doors.

When the elevator arrives, the doors will open. The broom will fall down, into the elevator.

The elevator doors will be unable to re-close because the broom will be laying across the threshold, blocking them.

Finish brushing your teeth and the elevator will be waiting for you. Remember to take the broom with you, and tell no one what you are doing.....

Well, uh, the OP mentioned "peak travel times"... what's to keep a manager from picking up the broom and throwing it out?

Andy comments: Nothing, if the manager finds out what's going on....

If he happens to come up to that floor and the broom falls down, he'll just think some careless person left it there....... and set it outside. Then the OP will know that he has been discovered.... And change to another method..... He's smart.... He can adapt.....

It's a heck of a lot more likely to work than having an amateur whose never built anything taking apart the elevator and putting in some claptrap electronics stuff, and maybe being billed for the repairs when it is discovered....as well as vandalism, violating a lease, and I don't know what-all.....

No, a broom is good. Maybe a walking stick.... Remember, it will only be used for a minute or so, so he can get to the elevator before the doors close and it goes away......Heck, he can tie some cowbells to the handle so he can hear it fall.......It ain't rocket surgery... :>)))

... we are, of course, assuming the manager doesn't read this newsgroup... :>)))))

Brilliant! So even if the elevator comes down from another floor, and is full of people, someone would just put put the broom back outside. You're right... it's a broom, not an EMP shock rifle or anything unusual...

Highly unlikely. Unless the manager got his MBA after getting his engineering degree... my cousin did that...

Wow, a city of 340 people? Neato!

We have no traffic lights, no police, no jail, no liquor stores, and only one cemetery. Situated on the shores of the third largest lake in Texas, this idyllic wilderness setting is home to an amazing diversity of wildlife, including the legendary Texas redneck. In fact, in 2000, the Texas wildlife association counted approx 340 nesting rednecks, secure in their wild life.

Does your house have wheels, or is it propped up on cinder blocks ?:-)

Well, our local school had a car wash to raise money to buy a new trailer hitch for city hall....

And Jeff Foxworthy's birthday is a school holiday. All the city services shut down, and the gas station doesn't open back up till the mayor runs out of bait......
