I have:
1x Alarmclock transformer
1x 330v 1oouf capacitor
1x 330v 80uf capacitor
1x Red 10 module led bar graph
3x Breadboards
1x 9v battery
1x 9v clip
10x Green led's
Lots of resistors
Lots of wire
I am hoping to build a charging circuit for the cap's
and using the bar graph as a charge meter,
but am not confident to design it myself,
don't mind buying ic's,
if you come up with anything or find anything please reply to this thread

what i want to do is to charge the caps using the 9v battery through the transformer reversed
so that i can power up another project
broke my multimeter last week(stepped on it)so cant use,
If I understand you correctly, what you're aiming for is an inverter circuit to convert 9V DC to something like 300V DC. Are you aware of the risks involved? A 100uF cap charged up to 300V could KILL YOU !!

Forrest Mims had a nice LED bar graph (you could use individual LED's) in the RadioShack series he published. Something similar is here on page 68:

Yes, you had the component, but there was no indication in your post that you had any clue how to use it. That is why I bothered to look up the link for you.

yeah i do know how to use most of the components e.g the transformer inverted, the leds the bar graph, im just not very good with ic's and the circuit designing side
Do you know (or can you find out) what are the energy requirements of the coil gun? That is, voltage level (E) times current (I) to calculate Watts, times the duration of the pulse (in seconds), needed to have the coil gun operate as expected? This value is usually expressed in Joules (or, perhaps, just ergs [0.000001 joules). This value will determine the circuit design utilizing the components you have on hand, plus whatever else is needed.
