Last year I built a compressed air rocket launcher which was featured in MAKE Magazine. The rocket launcher is a heap of fun and my kids love it. The rockets themselves are made from paper and masking tape and are surprisingly strong and robust. So strong in fact that you can tape a “spy” camera to one and shoot it off and get some great aerial footage as I did in this Instructable.
One of the drawbacks of the design is you need to have a wire attached to the launcher and then trigger with a switch at the other end whenever you want to launch a rocket. The wire has to be long as you don’t want to get too close to the rocket when it goes off, and it always seems to get tangled and twisted.
To alleviate this I decided to add a remote control to the launcher and get rid of the wire altogether. After a little searching I found this remote control on EBay. It only set me back a couple of bucks and works like a charm.

This Instructable is really just a guideline on how to wire one of the remotes up as I couldn’t find much at all on the net.
I hope it also gives you a few ideas on what you could hook one of these remotes up to.
Step 1: Things to Gather
1. 2 X 9V battery clips
3. Remote control and receiver – try eBay
4. Project box
5. Wire connecting terminal (terminal block)
6. Heat shrink
1. Soldering iron
2. Wire snips
4. Small Phillips head
5. Small Screwdriver
