    Good evening boys and girls! Today we'll be running through a safety removal and voltage upgrade on the newly released Nerf Stryfe.

    ___________________________________________________________________________
    Tools and Materials Required

    Phillips head screwdriver
    Soldering iron and solder
    Wire strippers
    Electrical tape/heat shrink
    ___________________________________________________________________________

    Allright, go time!

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6077

    We'll start by removing all the screws from the shell.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6078

    There are two different sized screws in the shell which we'll need to remember when we come back to reassembly.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6079

    There are two of the smaller screws and they both go here.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6080

    Ok, once we're inside take a moment or two to try and get an understanding of the internals and how they work. It will help with reassembly to no end.

    Cool, lets get back to it. Start by removing the screw that holds the trigger lever in place.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6087

    Which will then let us remove the whole dart pusher assembly.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6088

    Then remove the jam door.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6089

    Then the trigger. It's held in place by this screw.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6090

    Bam! and the trigger is gone...

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6091

    This is the first safety that we'll be removing today. It checks that there's a clip in the blaster and will cut power to the motors if there isn't. I don't want that feature so it goes.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6092

    Once we remove the cover we'll find the micro switch. Remove the orange bits here.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6093

    Like so.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6094

    Then we'll move to the top of the blaster and examine the dart checker safety thing. This little orange piece here checks that there's a dart in the clip and won't let you pull the trigger without one.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6095

    Clip in, no dart = dart checker down

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6096

    Clip in, with dart = dart checker up.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6097

    With the dart checker down (and the dart pusher back in for the sake of the photo) we can see how it blocks the dart pusher.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6098

    While when it's up we can see that it clears. Understand? Cool.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6100

    So to get around the dart checker, we're just going to plain old remove it. Even if you do no other mods from this guide, I'd strongly recommend removing it. Many people have reported issues with non-elite clips not triggering the dart pusher so let's just remove that whole possibility.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6101

    Next up we'll remove the microswitch that checks if the jam door is closed. We don't need that either.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6102

    Now at this point we should have two microswitches floating in the shell. We need to bypass these.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6103

    To do this we'll start by de-soldering both the orange and blue wires from the bottom switch.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6104

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6105

    The top switch is a little more complicated. It has two negative inputs, one form the trigger and one direct from the battery, and one output. In absolution it's essentially just a switch on the negative wire between the battery and the motor.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6106

    Pull the heat shrink back.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6107

    Desolder the red wire.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6108

    Then solder it to to the blue wire we removed from the other switch we removed earlier.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6109

    Now let's move to the thermistor. I apparently forgot to take a photo at this point but if we refer back to a photo from the start...

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6086

    We'll see that it's held in by a screw. Remove that.

    The thermistor is a component that apparently seems to confuse a lot of people but it's a really simply component. Essentially the more voltage you run through it, the hotter it gets; the hotter it gets, the higher resistance it provides. For us this means that once it reaches a certain temperature it cuts power to the motors. This particular thermistor will cut power after a few minutes of use at 9v, or almost instantly at 16v. Because we want to increase the voltage, we have to remove it.

    To do this simply desolder the black wire from the thermistor and solder it directly to the negative terminal on the battery.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6111

    Also, good point to mention that we taped the red/blue connection we made earlier. Heat shrink would be better but I'm lazy.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6112

    That's about it folks; time for reassembly!

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6113

    First, the dart pusher and spring. One screw to hold it in and we need to slip the spring over the post at the end.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6114

    Then the trigger.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6115

    Then the jam door.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6116

    Then the other half of the shell.

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6078

    Ok, not quite done; we still need to up the voltage. I've been tossing up between three trustfires and one dummy, or two trustfires and two dummies, and I'm honestly not sure what I prefer yet. Three batteries is obviously more powerful, but it's less accurate and makes a stupider noise. I don't know...

    Nerf Stryfe - Voltage Upgrade and Safety Removal DSCN6126

    Which ever way you choose to power your Stryfe though, you should still be pretty happy with it.

    They are a very odd set of Duracell batteries you have there Jeo lol.

    Great write up again. Would suggest getting some heat shrink instead of electrical tape, not that it really matters though it looks better, more professional
