Weekend Project: Simple rocket launcher

For years I have wanted to make a simple device to launch a model rocket. This Saturday, my son Tim and I built it at the Makerspace. The launcher consists of a project box with some external connectors for the wires that go to the rocket, an arming switch, an LED to signal that the circuit is good, and a launch button. It took about four hours to make including several mistakes and backtracks.

We tested the circuit and it works as planned. The real test will be tomorrow when we attempt to launch some rockets at the park.
