Ok I lied :behave :lol
I actually managed to get a few bits done in a short time for once.
Here's the charging circuit in action (though for some reason two LEDs aren't lighting up, but it's good enough I think).
(the fan is barly audible once the two halves are screwed together)
Whilst I was still scratching my head and wrestling with making the circuit, Majenko must have taken pity on me (or got fed up with my barrage of stupid questions
) and very kindly made this tiny custom charge PCB for me which arrived at the w/e (what a dude :cool)
I slapped on a few quick connectors, 3mm LEDs and headers for a fan (I like modular where I can impliment it, it makes for easy troubleshooting) and fed it some juice (cue angelic chorus).
I'm in two minds now, I'm really chuffed I managed to get my charge circuit all working (bar the two LEDs), but it's a bit messy, and majenko's is so cool.
In order not to drive myself mad with indicision I turned to finding a place for the mag and mode switches. In order to keep things simple, I'm attempting to place the electronics on the one side if possible. While the wires are a little close to moving parts, they will eventually be secured out of the way, and it stops the chances of snapping wires when opening the gun up if there aren't any attached to both sides.
I toyed with a reed switch/magnet setup but felt it might interfere with Majenko's FX module being such a strong magnet, so opted for a submicro switch instead.
It was at this point I wish I had a clear recon to use as a template, but after much toying with placement that I discovered the best place was by the magazine latch
It needs to be about 1.5 - 2mm from the top of the wall to give the mag overhang and switch button a bit of clearance.
The magazine slides the switch closed very smoothly, and I bent the switch paddle down at the end a bit so it won't catch the mag on its way out. The other thing I noticed is the mag doesn't go in comfortably if put in the wrong way round, this is becouse the guide tracks on the switch side a wider allowing the switch paddle to pass with no probs. the other side is thinner and catches the paddle a bit on the way in making it feel wrong (possibly handy in dark situations :thumbsup).
Just the mode switch to go now and I think it'll end up somewhere near the grenade launcher for ease of access and usability.
To be honest I can't wait to start on the bodywork (especially seeing that awesome SPAS cage mod), and I won't be able to find stash places for the last remaining bits n bobs without the shroud, so after I've made the battery pack it's off to the printers for me on payday.
Oh yeh, and this is Majenko's new MkII PR FX module (for those inquiring earlier)
Now I think I can hand this thread back :behave. :lol
