Hi All:
Working at a summer day camp and would like to have the kids experience a "space" program by building a model rocket, going through different phases leading up to launch and recovery. I have designated some of the kids as "mission control" - who will be responsible for launching the rocket. However, I want to be the actual finger on the button to avoid any misfires.
I bought myself a wireless doorbell, thinking I could hack that to allow for my launch trigger - however it seems replacing the speaker with the actual igniter just isn't producing enough current to light the ignitor. Any ideas how I may be able to do this easily?
My first thought is to hook up a relay to the speaker wires, but all that may do is cause the relay coil to act as the speaker coil... I'm befuddled, since I have no electronics experience outside of college physics...
Thanks!
Max
