Maverick (Nerf) Mod: custom blaster build log


Looking to do a Nerf gun mod... wanted to get some feedback on how to paint/weather it..

found a few projects on-line that I thought we pretty decent.. trying to decide on my own direction here.

1.) black & silver based (techy) theme

2.) heavy metal/blade runner feel (really digging this one and the wooden/brown handle on it)

3.) Army green & black style:

4.) silver & black (mas effect I think? not a gamer).. really like this style too.. even the logo (of some kind) looks right

5.) mixture, black, silver & brown grip..

Secondly.. a few other questions.. ;)

1.) how important (cool points?) is that the nerf gun still works as a nerf gun? Ive been thinking of removing the working 'dart' aspect of it.. in favor of some electronics goodness instead?? thoughts?

2.) anyone else have a blaster project in the works??

-----------------------------[update after some work]--------------------------------


after some work.. I made some progress on this project. ;)

I got the electronics all figured out.. (including making/baking/assembling the board, writing/finalizing the code, home brew/etching two additional custom pcb's...yadda yadda)

It is powered by S.C.A.B... :)
[kinda my generic/general platform for far I love it]

I think I had posted pics of making my board somewhere before.. (in another thread currently running about)..

here it was it looks like:

here it is on the left next to an Arduino board (with a WaveShield stacked on top of it for comparison)

(fonts changeable on SD card, reads/loads a few defaults off a text file on SD card as well to set a few parameters on the blaster)

*safety = if on.. you need to have the trigger pressed when you boot up

*maxammo = total ammo count before having to reload

*acolor = led color when in auto-fire mode (can be r, b, or g)

*acolor = led color when in semi/manual fire mode (can be r, b, or g)

here is the first video of stage/phase one of the electronics and code development stage of it:

Prepping the nerf gun: (in no particular order)

*I needed a motor.. but didnt really know how I was gonna make it all work.. about torque on motors...sizes..etc..
got lucky and scored a motor that looked like it would fit from my local science surplus store.. biggest I could find that was small enough to still (it seemed like it was MADE for the gun once I got it home)

*I knew I need to somehow get some leds into the barrel.. and wanted to have it be RGB..

*Wanted it to reload by pulling the slide on top back

*Since its a blaster the SD card and batteries needed to be accessible without having to open the the gun up (ie: accessible sd card and re-charge port)

*Needed to account for a switch/button to switch from semi/manual firing mode to auto-firing mode

here was my first mock up for testing space and how I was gonna attempt things: (pre dynamic default loading)

(s.c.a.b. in grip/butt)

after taking apart the Maverick gun (many tutorials all over on it if needed).. I saw how the barrel was turned internally by trigger pull.. and figured Id hack/modify it to suit my needs.
I cut/sanded the hexed shaped top off the post/part that connected to the barrel and turned a little inner sleeve and press fit hole so it would attach to the cut down motor shaft.

before/after motors:

** what you dont see pictured is any pics of the custom PCB I etched for the components to drive the motor (SCAB/Arduino do not have enough power itself to drive high power devices.. so you need a driver/transistor...etc.. something to help out)

but here are the shcematic and pcb files I made in eagle for it:

[img width=568 height=768]" />

RGB barrel LED:

I was going to use a DX RGB led star I had laying around.. but then decided it was over kill for a blaster (not like I need to light up a poly tube/blade or anything)..
so I opted for a 505 RGB led,.

*created a custom home etched pcb for it
*turned down a two piece optics holder and pcb 'presser up againster' unit to hold everything.. (similar to Ace's small OD optics/holders... but mine are much more shitty and crude..and no threading....well you get the point).. haha..

I wont go into detail on how I etched.. I have posted a few tutorials stp-by-step on how to make these at home in 10 minutes enough..

after etching.. smear some solder paste.. and populate board with resistors & 505 RGB:

bake it in toaster oven:

make inner sleeve/bottom portion to hold/push the pcb with (incuding some milled out section for wire passing)

make outter sleeve to hold optics in it.. and also has the bottom portion slide in and sandwhich the pcb up against the optics......and fits in the Maverick gun plastic barrel part:

Unit all put together:

Inside the Maverick barrel:

Exploded view of all parts/optics/pcb..etc:


Mode select switch.. had to think about where I was gonna put this.. without some huge, ugly slider switch somewhere.. that looked like an after-thought...
I eventually decided to re-purpose the same button/area that used to allow the barrel to swing out and reload the darts..
*(this switch has an led in it.. I am nto currently using it.. but could be used to have the switch backlit.. I have a 3.3v pad on the board)

using a simple lever switch.. for both both main trigger and reload..

reload switch:
this one is secured to some perfboard cut to snug fit for inside the gun area.. it positions it in the correct place so the top slide hits it when pulled back, w/o mod to the top slide area/parts

main trigger:
you can see where I placed it int he above overview shot of the gun layout..

I mod'd/filed down the trigger a bit to hold the lever from the switch it in easier...(works great!)

after getting all this work and aligning things up.. I did a quick mock-up and cram-fu test with it mostly assembled.. (some parts have to wait for final paint and/or assembly)..

I took this video of its current state.. which Im calling 'done'.. and ready for break down and final paint & weathering (attempts) lol

thanks for the poll/feedback..

Im still not sure about trying a chrome/silver/nickle base and some dark washes.. or going with a black base..and trying to silver/grey dry brushing..etc.

(better decide soon eh?) lol
