SwarmTurret V2: Wifi Controlled Foam Dart Turret

The SwarmTurret is a wifi-controlled foam dart turret with streaming video that is fully controllable from a mobile device or desktop browser. I built the first one a few years ago and finally just got around to posting my updates to it.

This build has gone through several iterations but this this latest redesign is easier to build and better. Some of the major upgrades include:

• Reuse of existing plastic blaster shell for easier assembly and less printing
• New belt controlled y-axis for better stability, adjustable belt tension
• Better camera placement for improve accuracy
• Direct x-axis control instead of gears
• Upgrade from pi 4 to pi 5 to allow for faster web server performance
• Integrated power supply with on/off switch
• Other minor improvements
