coil gun questions

hi, i am building a coil gun, and i need to make a board or something that can read the number of volts that is coming from the capacitors. i have 2 banks of 4 capacitors running in a parralel style, that are 1000v each. i would like to have 3 lcd number screens( 1 for each bank, and 1 for all together) that display the volts. here is a horrible drawing of the schamatic of what i have so far.

i now realize i may have messed it up a little, but you get the idea

How many volts are you planning on charging the capacitors up to
If it is very high (1000V ??), then what safety measures are you planning
what is your charging circuit going to be ?

Please provide this info so we can provide better advice

Some times questions regarding electronic equipment are a bit strange.

If person making capacitor bank, that will be charged above 1000V, and don't know how to read voltage, maybe you should not make it in the first place (safety reasons)?

There are enough guns and killing in the world already - I won't be helping you make any more.

i am planing to get all the capacitors up to at least 500v.

Hence the probing questions, I want to know what is being built here and the intended use ? before I provide answers / help

i a just building this for fun because i saw it on a video on youtube. it was about capacitors, and what can be done with them]

There's no fun in guns - if you want to mess with putting lots of charge into capacitors and letting out in a hurry with an attendant visible effect try making a Xenon flash tube strobe - which you can then use to observe rotating objects or dazzle your pals at parties - according to your taste. Much the same physics and no death.

Or if you want to get mildly lethal you can repeat my teenage experiments with trying to do the same thing (strobing) with standard fluorescent tubes - I only ever got one flash out of mine and they would never work again but I think I was doing something wrong ! (Too long ago now to have much idea of exactly what.)

The required voltages are still quite high so you need to be very careful.
