ok so iv been following thing tutorial i found on youtube

http://www.youtube.com/watch?v=ny9D6BDD4C4#ws-lq-lq2-hq-hd

i only used 1 resistor and instead of a second 1 i used a potentiometer so i can adjust the fire rate for WaW , the potentiometer connects from 6 -> 7

m going to put it like this eg. 1-2 which means pin 1 goes to pin 2 ok:
wire leading off 1
wire leading off 8
2-6
4-8
resistor from 8-7
then another from 7-6
negetive side of copasitor goes to 1
positive side goes to 6
then have a wire leading off 3
solder 1 to ground 8 to switch toher side of switch to positive
and 3 goes to middle trigger pin

that is the basic setup for the 555 timer , but every time i use that setup ... my automatic guns nvr stop shooting idk why ....

so i changed the setup and did

pin 1 to ground. pin 8 to possitive. and pin 3 to switch, tehn other side of switch goes to the center trigger point.

the mod works now but when i try to adjust it with the potentiometer it doesnt slow it down ... and sometimes it just does single shots im so frustrated >:|

These are the materials i have 555 timer a couple 1Kohm resistors micro-size Potentiometer , 10uF Capacitor HELP

I dont have time to watch the whole video, but the demo program I have states as setp up like you typed it it blows up the 555??

you need to follow this tut.

https://www.acidmods.com/forum/index.php?topic=25338.0

the pot should be at pins 2-7
the only thisng that needs to be at pin six is a jumper??????

I will watch the video when I get time, and plug it into the program to see what it does
