Nerf guns can be a lot of fun, but what if you want your launcher to shoot 10 projectiles simultaneously? Is so, then look no further than James Bruton’s custom blaster.
His 3D-printed project employs two BLDC-powered rollers to accelerate cartridges of 10 darts each, and allows for quick reloading via a clever manual locking mechanism. The device holds five magazines, for total of 50 darts.
When loaded, an arcade-style button fires the darts, pushing them into the rollers at the same time using a couple of servo motors. Everything is powered by a six-cell 24V LiPo battery, while an Arduino Mega is used for control, and to track which cartridge is in place, enabling the operator to concentrate on getting shots downrange!
