A project true to the series title, Weekend Projects, our latest offering, 10-Rail Model Rocket Mega-Launcher, is a true weekend build but will actually save you time in the end. Instead of launching model rockets one at a time, or trying to time multiple stations to launch simultaneously, this project is designed to launch 10 rockets from one “mega launch” switch! Once armed, you can fire the rockets individually, but there’s something extremely rewarding about watching many rockets ignite within seconds of each other.


A fairly complex circuit (most powered by a 12V sealed lead acid battery usually are), the “guts” of the circuit are visible, mounted on clear pieces of polycarbonate. This “clarity” aids in educating young model rocket enthusiasts, allowing you to trace wires and point to respective diodes. So a cubby, for example, will not only have the satisfaction of pressing a launch button, but of seeing how it works.

This project will also introduce some new components to our arsenal of Weekend Projects parts, namely the DC voltage regulator, which as the name suggests, regulates a specific output voltage, in this case 5V. Watch the video below for more tips on assembling your 10-Rail Launcher, and to see the launch in action. This project is ideal for rocket clubs and will add an amazing “wow” factor to any launch event!
