 I finished making the rocket launcher and it works as designed -- it puts out about six volts of electricity when I push the launch button.  However, it failed to launch a rocket.  It could be that the batteries were worn down or it could be that the rocket ignitor needs more power.  Also, the LED I installed does not light.  Maybe I wired it in backwards.  The LED is not required for the launcher to work, so I will consider this part of the project done.  I will try to fix the problems in the next project. I finished making the rocket launcher and it works as designed -- it puts out about six volts of electricity when I push the launch button.  However, it failed to launch a rocket.  It could be that the batteries were worn down or it could be that the rocket ignitor needs more power.  Also, the LED I installed does not light.  Maybe I wired it in backwards.  The LED is not required for the launcher to work, so I will consider this part of the project done.  I will try to fix the problems in the next project.

 +[20 September 2013 Update].  I fixed all of the basic design issues with the launcher.  I added some posts so I can use any external battery power source.  The LED was replaced with a bigger one that works.  Finally, the switch was replaced with one that works.  Now, everything works as designed and the launcher will actually launch a rocket.
