I've been flying through this build without taking many in progress photos.
I installed the folding stock, bayonet lug, and some of the other greebles.
I put down a quick coat of silver paint and a few coats of black. I want to get some paint on the parts of the blaster that would be difficult to hit later when fully assembled.
Today I worked on the electronics.
I started by extending all the wiring. The existing cables were just long enough to fit the Disney E11 but not long enough for what I've planned. I ordered a bundle of 200mm dupont cables and stripped the connectors. I kept all the wiring the same color as the original assembly so I could reference my unmodified wiring photo.
I was unable to salvage the battery holder from the Disney E11 so I ordered the smallest one I could find from amazon.
5.2 x 3.6 x 1.2cm/ 2" x1.4" x 0.5"(L*W*H)
There was only one reasonable place to add the battery pack so I started to hollow out the magazine holder. This was tedious, I imagine I put about four hours into grinding and sanding this down to the point it would fit the battery pack. To add extra room for the battery I cut a hole in the blaster body.
I ordered a replacement magazine from Steve (Gazmosis.) With a little sanding on the magazine and magazine holder I was able to get a a solid press fit. I'm trying to figure out a better way to mount this together where i can still access the battery compartment when needed. Probably magnets.
I'm sure there is a much more elegant way to install the trigger mechanism and mode selector switch but this is what I came up with.
The trigger switch was installed under the trigger. To make the trigger movable I drilled a hole through the trigger housing and the trigger itself. I added a pin so it could hinge back and forth. The tension on the trigger button is enough to reset the trigger back to the original position.
I drilled out a recess in the back of the handle to allow room for the mode selector switch. I apologize for the horrible photo, I assure you in the middle of that mess is the mode switch.
Here's an idea of how it all comes together.
The board sits under the battery pack in the magazine housing. If you refer back to previous picture you can see I used a screw to secure the handle. There is enough clearance under the screw to fit the chip securely.
I have to admit I don't know anything about electronics. The LED's are currently mounted to the microchip. I've removed them from the board. Is it possible to solder the LED's to the wires and solder the wires to the original LED position on the board? It looks like there are two solder points for each LED, should I use two wires for each?
This whole project requires a lot of cleanup. Although I was able to fill the original hole I created in the top t-track, I ended up over-sanding.
By the end of this it's going to be more green stuff then resin. Still having a blast hacking away at this thing.
