I grew up building and launching model rockets. Many evenings and weekends were spent huddled over a model rocket, getting it ready to fly, and sending it to the clouds. My father-in-law and I are looking to launch some rockets this summer with my kids and I want to create a better launch controller than what comes with the standard Estes launch kits.

Using Onshape, I've created a rugged box with a panel inside that holds launch controls. There will be a switch to power the unit, a switch to test continuity, and the launch button.

Using TinkerCAD Circuits, I created a simple setup that I've been able to test and make sure the system sees the proper currents at each stage.
