Picture of RC Rocket Launch System
This instructable will show you how to make an RC launch system for your Estes rocket, which can be operated with a TV remote. What it does is it allows you to press the center button on your TV remote, and it'll automatically launch your rocket. In this way it is basically a wireless version of the standard launch controller. But this is not all it does. You can use the up and down arrows on your remote to set a delay, and you can use its count-down feature to ignite it like a time-bomb. It works with just about every TV remote, and uses standard rocket igniters.

1. Clip alligator clips to igniter.
2. Plug 9v battery into Arduino.
3. The screen should say "0 delay"
4. Press up and down on your remote until it says the exact number of seconds you want it to countdown from.
5. When ready to launch, walk away from the rocket (without worrying about how far the cable stretches) and press the center button on your TV remote.
6. It'll countdown from the number you chose (displaying the countdown on the bottom row of the LCD) and your rocket will be up in the air!

Here is a poor quality video showing the device activating an igniter. Just imagine that the igniter is inside a rocket.

Step 1: Supplies

Here are all the supplies you'll need:
1 Estes Launch Controller
1 Arduino
1 5v Relay
1 LCD screen (for displaying countdown)
1 IR receiver diode
1 NPN transistor
1 10k resistor
1 diode
The IRremote library

Step 2: Remove Controller Back

You should hopefully know how to do this. Flip the launch controller over, and remove the screws on the back. Then take off the back.

Step 3: Open it up even further

Now you will open it up to see the inner workings of it. I don't think that Estes condones doing this, but who cares? Look at the pictures and pry the pictured panel off.
Very nice, was working on a rc rocket launcher myself for the RC contest, just not in the cards time wise. Yours is very cool, nicely done!
