How can i use these parts for coilgun?

[TheWeakestLink]

i have a 54 volt power supply (salvaged, confirmed functional), a decent sized coil of solid copper wire rated up to 600 volts, various salvaged components (some confirmed functional, others untested. All acquired from dismantling old or broken machines, examples: various unsorted capacitors, fuses, resistors, speakers, logic chips [i think. they did come from a VGA expansion card], hundreds of other things i cant hope to remember...)
i additionaly have about 15 9-volt batteries (total possible output for 9-volts combined: 135 volts) and 2 200-volt, 680- microfarad capacitors. allong with additional capacitors taken from old power supply units.

i need to figgure out what i can do with these ardurino parts to make a coilgun:

im worried about using the batteries in seiries, because while it will be good in terms of the voltage, and the voltage across the joined teminals is fine, the voltage across each individual terminal is multiple times highr than the battery's rating (135 volt difference on terminals made for a 9 volt diference)

please let me know of any sugestions, or info i forgot to add, because i can upload image and maybe gif of the testing phases.

also, i currently am gonna use a relay to dump the capacitor into the coil once charged.

IMPORTANT NOTICE: i discovered that my parts arent ardurino, they are off-brand clones.

You only write about voltages. Coil guns only operate based on current, Amperes! If you cannot supply the current to make the magnetism pulses, you have no gun.

Use the Arduino to signal a phone to dial 112/911.

The parts shown above would make a fun little robot, but not a coil gun.

You will need a lot of mechanical/engineering knowledge too...
Coil guns that have any power at all are very hard to make as they must be able to withstand extreme sudden forces.

This tutorial shows how to make a coilgun from a camera flash module and some wire.

Nice drawings!

i only refered to the voltage because they are directly related. im pretty sure my 52 volt power supply provided either 5, or 2.5 amps

[TheWeakestLink]

that's where i got the Arduino parts from, not some kit for the gun. im making the other parts.

thanks! ill check it out. luckily i probably either have, or can make most components

[TheWeakestLink]

true, i plan on using PE-LD-04 (polyethylene low-density closed cell foam) strips and a spring to make a firing support capable of handling the stresses expected from operating the coilgun.
