This is Halo's SPNKR (geddit) rocket launcher somehow constructed as a real and working 'weapon', with rotating barrels like in the game. And it plays the Halo theme.

The rocket launcher itself is assembled out of off-the-shelf pipe and 3D printed components. An Arduino Uno runs the show, hooked up to a Bluetooth module and a laser rangefinder.

Great build, thank you for sharing it. I built a rocket launch controller for my grandson some years ago. It wasn’t nearly as nice or elaborate as Eddy’s, but I did include a 100 uA meter ...

The first stepping stone vehicle would be the "Launcher Light" rocket, with a single first-stage engine, ready for flight by 2024 with a capacity of 150kg to low-Earth orbit.

Launcher Inc., a space launch startup that tested its 3D-printed rocket engines at Calverton, has been acquired by a California space station developer, the companies announced.

Now, 80 years to the week since the last V-2 launch of World War II, Germany again has a homegrown liquid-fueled rocket on the launch pad. This time, it's for a much different purpose.
