[Rp181] has documented his entire rail gun build. He takes us through collecting the materials and assembling the system. It required 18 400V 3900uf capacitors to get the 5600 joules he wanted. It looks pretty impressive, though a video of it wreaking havoc on something might have been nice. We’ve seen rail guns before, from tiny ones for a robosapien to larger jobs very similar to this one. In his instructable, he touts this as a “green” system. The capacitors are aluminum and no gun powder is required to relocation the projectile. anybody want to do the math to figure out if it really is any better? maybe if he’s collecting his energy through a huge solar panel.
