Upgrading the SwarmTurret

A few years ago, I built a Wi-Fi-controlled Nerf turret, but I never got around to creating a proper build guide for it. When I finally sat down to write one, I realized just how many things I would do differently. That realization quickly snowballed into a full redesign—and the result is a vastly improved version of the SwarmTurret.

This new version is not only more powerful and precise, but it’s also easier build. Here are some of the major upgrades:

• Simplified Assembly: I reused the shell of an existing plastic blaster, which significantly cuts down on 3D printing and makes putting it together much easier.

• Improved Stability: A new belt-driven Y-axis adds smoother motion and includes an adjustable tension system.

• Enhanced Accuracy: The camera has been repositioned for better aiming precision.

• Direct X-Axis Drive: I replaced the original gear system with direct motor control for more responsive movement.

• Performance Boost: Upgraded from Raspberry Pi 4 to Pi 5 for faster web app performance.

• Integrated Power Supply: Now features a built-in power supply with an on/off switch—no more fumbling with cables.

• Web App Enhancements: The control interface is more intuitive and responsive.

I’ve published the complete build guide, along with the updated code and 3D printable parts.
