:: Voltage Increase ::
As the Barricade is a flywheel based blaster, the faster the flywheel motors spin the faster foam darts get fired out, hence longer range and faster dart velocity.
To increase the speed of the motors, simply increase the voltage feed.
In my examples, i use 14500 size 3.7V Li-Ion Rechargeable Batteries (Brand: TrustFire / Unprotected versions) in my modded Barricades. The batteries can be sourced from specialist electronics stores.
14500 size 3.7V Li-Ion TrustFire rechargeable batteries are usually charged up to 4.2V, so i use 2 of them with a dummy AA battery in the 3rd battery slot. This configuration provides 8.4 Volts of power to the Barricade's motors.
With 8.4 Volts of power, the Barricade's motors spin much faster and the start-up response time is also quicker.
See the test fire video below for the range results based on this increased voltage.
Note that i have tested it with 3 x fully charged unprotected TrustFire Li-Ion rechargeable batteries with a total of 12.6 Volts, but the motors did not move. Therefore, it seems that 12.6 Volts from unprotected Li-Ion batteries is perhaps too much for the stock motors to handle, due to the higher discharge rates of these batteries.
Alkaline batteries have more limited discharge rates, and will therefore perform differently at the same voltage compared to these unprotected TrustFire Li-Ion batteries.
:: Trigger Activated Power On ::
Stock Barricades require their motors to be separately switched on, then constantly running to be able to fire.... but the motors will still be spinning even when its not firing anything!
This creates an incredibly annoying constant buzzing sound that has put off many players from using Barricades, not to mention the added power drain on the batteries.
I've worked out a way to solve this issue by installing a pressure switch which would be activated by the trigger pull instead.
Interestingly, the stock Nerf Barricade already has a pressure switch included for modders to use... its just under the original On/Off switch!
Step 1: Open the internal cover to the On/Off switch and you will find a pressure switch. Remove it and detach it from the circuit.
Step 2: Locate the area directly under the trigger, cut a slot around the size of the pressure switch and make sure it is aligned so that the trigger will be able to slide properly over the pressure switch.
Use the cut-out piece of plastic to make a ledge, this will serve as a holder for the pressure switch.
Step 3: Glue the pressure switch onto the plastic ledge and make sure it is positioned properly to allow the trigger to slide over it and depress the switch smoothly.
Connect the pressure switch to the circuit with some additional wiring.
Solder all the parts and wires together and wrap electrical tap on all exposed wiring.
This is how the new circuit should look like.
Thats it! Now your Barricade motors will only spin when you want to fire it.
The key to efficient usage is to simply pull the trigger a quarter way to get the motors spinning. As the motors start-up response time is much faster at higher voltage feeds, its just a split second before you can fire shots continuously.
With abit of practice, you'll be able to use it as a quick draw sidearm!
After firing, just release the trigger and the motors will stop spinning. No more constant buzzing when not firing!
Although the original On/Off switch is now no longer functional, it still acts as a useful trigger "safety" lock. So you can slide it forward to prevent accidental trigger pulls.
:: Flywheel Width Adjustment ::
For modders who want to use other types of foam darts, especially those which have narrower tips (ie. streamlines or stefans), one solution is to adjust the width of the flywheels.
In my example, i simply use electrical tape to increase the width of the flywheels.
The amount of tape layers required will depend on the foam darts used, so its up to modders to test and find the best combination of tape layers to apply.
Note that the plastic casings and ramps around the flywheels would need to be trimmed if thicker layers of material are wrapped around the flywheels, or else the wheels may get stuck.
:: Stefan Compatibility ::
For modders who want to use stefans or foam darts that are much shorter than normal stock foam darts, here is an idea you can try.
Slot separate foam spacer pieces in the barrels behind each stefan or short foam dart. The Barricade's dart pusher rod will push the foam spacer piece which in turn will push the stefan forward into the flywheels to be fired out.
