also, i got my rapid fire finished last night, and when i installed it and tested it, it didn't work that well. i can pull the trigger faster myself, and it was incredibly unreliable, sometimes it would work when i pulled the trigger and sometimes it wouldn't. Usually it just started randomly firing without me even pulling the trigger. so i bought all the parts from radioshack needed to build a second one, but can someone explain why that happened? did i burn out the 555 or transistor when soldering? I also bought a socket for the next one i'm building, so im not soldering directly onto the 555 chip itself. but i'd like to know how i can fix the first board also.
after checking around, i noticed that people made a small separate transistor board for the left trigger that just connects to the main 555 board.also, i got my rapid fire finished last night, and when i installed it and tested it, it didn't work that well. i can pull the trigger faster myself, and it was incredibly unreliable, sometimes it would work when i pulled the trigger and sometimes it wouldn't.

well i built two, and neither worked, there aren't any shorts and i know i got the right parts because i had the tut pulled up on my phone while i was getting the parts at radioshack. so idk what to do, i've already sunk about $30 into this project and i'm not too excited about building another.
well the fun part about it is building the thing, but i'm gonna pick up a breadboard and try to build it like that, maybe i'm messing up because of overheating the components.
watch the polarity of the cap at pins one and two. the cap should have a small + on it
positive goes to pin two, I thought you read the tut??? it is listed on step #4 of building the chip.???? I took alot of time to spell this all out and make it easy to follow. please READ THE TUT!!
yea, you need a 15 watt iron. also, get one that you can unscrew the tip and put a new one in. radio shack has one with three tips, one of which being a fine point. it is the best for the price of $15. I am glad you got it going. no face book so i cant see the vid. but congrats. did you leave the pot in or out?
this little mod i made for dual trigger rapid fire should work, ill test it tonight. but here it is.
well, thats a new question worthy of answering. LOL one way is to just build another chip for the other side. I garantee this will worka second, and this is just theretical, would be to take pin three and solder an extra wire to it so you have two output wire, add another switch so they could work independatly and use the same transistor method for the left trigger as you did for the right. not sure how this will work though I will test when I get time. I have a feeling it may create too much drain on the 555, thus creating sparatic fire rates. I would suggest using the first option, I know it will work!!! and if you used two 555 circuts, you could have two different fire rates... not sure how that helps but yea, you get the point.
Sweet! i've been wondering how add an led indicator to this!
np glad it helped someone, remember this is adding on a seperate LED though not using one of the originals.
although, you probably could use one of the original leds pretty easily right?
but I think you need to look further into this idea.
I am not sure you can dump the voltage from the led like that. I need to test this, that being said, the drawing you made, the LED will allways be on, the switch should be on the other side of the splice. if you are going to do this make sure the switch used is vated +3v all mods that include an indicator supply more than one + voltage source to the led, and will have no affect on the player status.your initiative is very comendable, but I think you need to look further into this idea.
