Foam Dart Blaster

Product

Overview

The foam-dart blaster is a motorized flywheel toy gun. Rather than a single spring plunger, it uses two counter-rotating flywheels to grip and accelerate each dart, fed automatically from a detachable magazine by a motorized pusher. The result is rapid, repeatable fire as long as the trigger is held and darts remain in the magazine.

Everything mounts inside the Clamshell Housing, two molded half-shells with an integrated pistol grip screwed together. Body furniture clips on outside: a Barrel Shroud / Muzzle muzzle shroud, a Tactical Rail Set of tactical rails for accessories, and a Jam-Clearance Door for clearing stuck darts.

How it works

The heart of the blaster is the Flywheel System. Two brushed Flywheel Motor units spin rubber-rimmed flywheels held in a cage, with a dart guide between them. Pulling the rev trigger closes its microswitch and spins the wheels up to speed; when a dart is driven into the gap, the wheels pinch and fling it down the barrel.

Darts are rammed in by the Pusher Mechanism. A pusher motor turns a Pusher Gearbox, whose reduction gear set and cam convert rotation into the reciprocating stroke of the pusher rod, pushing one dart up from the Detachable Magazine into the spinning flywheels and retracting under a return spring. The magazine is a spring-fed stick that seats in the mag well, holding darts under a follower.

Firing is gated by the Trigger Group, whose main trigger microswitch and safety lockout block the motors unless a magazine is seated. The Control Board switches the flywheel and pusher motors through two MOSFETs from the trigger and rev inputs. Power comes from the Battery Tray, a removable tray of four 18650 cells on spring contacts, distributed through the internal Wire Bundle.
