Introduction: Wireless Remote Operated Nerf Rebelle Powerbelle Blaster

This is a simple project that is relatively inexpensive and will allow you to operate your blaster remotely.

Step 1: What You Will Need:

Full auto nerf blaster. I chose the Rebelle Powerbelle because unlike other full auto blasters, this one only uses a single trigger. There is no rev trigger since there are no flywheels...this makes the wiring very simple. The Speedswarm and the swarmfire would also be quite similar.

9v dc relay with wireless remote (roughly $15 on amazon)

small camera tripod ($5 at 5-Below)


philips screwdriver

soldering iron and solder

electrical tape


jbweld or some other glue

Step 2: Create Mount for Tripod

This is the easy part. Remove the battery cover.

Determine where you want to mount your tripod, i chose an area toward the front of the blaster. Set your T-Nut in the desired location and mark where the hole needs to be drilled. Drill a hole, then mount the T-Nut (any nut of the proper size would be fine) I used some JBWeld to hold the nut in place.

Step 3: Wire Up Your Relay

The wiring in this blaster is pretty simple. You have your battery tray, the black (-) wire connects to the motor PCB (-), the red (+) wire runs to the trigger switch, which then runs out with a blue (+) wire to the motor PCB (+).

in this circuit, the (+) wire is switched.

The relay that i purchased had four wires. Red, Black, Blue and Yellow. The black and red were to connect to the power source, and the blue and yellow connect to the motor. What they didn't mention in the documentation (because there was none) is that this unit switches the (-) wire instead of the (+) wire like the nerf gun does. This means that if you want to keep the trigger functional, you will have to rewire the original circuit so that the trigger switches the (-) wire instead of the (+).

It may be difficult to tell from the images, but here is how everything is wired up. This may be different for you if you purchase a different relay.

start by disconnecting both wires from the motor PCB and disconnect the red wire that goes from the battery tray to the trigger.

the (-) terminal on the battery tray connects to the Black wire on the relay, as well as the red wire from the trigger switch.

the (+) terminal on the battery tray connects to the Red wire on the relay

the Yellow wire on the relay connects to the (-) terminal on the motor PCB

the Blue wire from the trigger switch connects to the (-) terminal on the motor PCB

the Blue wire on the relay connects to the (+) terminal on the motor PCB

with everything wired up this way, the (+) wire runs through the relay and is always suppying power to the motor. both the relay and the trigger switch are wired up to switch the (-) wire, so by pressing either the trigger or the button on the wireless remote will complete the (-) connection and close the circuit, causing the blaster to fire.

Step 4: Assemble and Use

the relay has a small coiled up wire that is the antenna, straighten this out and run it along the open space in the top of the blaster (i forgot to take a picture of this)

Put the blaster back together. Thread the tripod into the nut you mounted earlier and you are ready to use your blaster. The wireless range on this relay is easily more than double the effective range of the blaster when fired.
