Oh you can build one out of literal trash from the 90s.
It's just... So there's a lot of energy in gunpowder. Like, a lot. And even being super inefficient and losing a ton if that energy, it's really good at pushing stuff. Its just naturally good at exploding, and over the years, we occasionally make it even better at exploding.
And we have some pretty good batteries but they really dont compare.
And then, you know, you need to release a shit ton of energy all at once right? And batteries aren't very good at that. Even if you make them be explosives instead of batteries, they still aren't anywhere near as good as gunpowder at that.
So you also need a capacitor. Which is more stuff.
And you've still got a really weak gun, and you need to charge it between shots-not just the battery, but the capacitors(?) In a way you can't really just rotate out-notice how there are three sections of wire there? Thats three thingies to accelerate the slug, which each need a quick (and super well timed but thats not usually a problem AFAIK) boop from a capacitor. So you can't fire fast for long even if youre carrying a huge battery. And overheating is a huuuge problem, because remember what heat does to conductivity. They are not friends.
So you can't use it in a sustained fight you can't (as easily) hurt someone armored and you can't make your dick feel big with it. Which are most of what militaries care about.
If I recall correctly there's also the issue of ballistics. The artillery rail guns have the projectile encased in a sabot AFAIK, something you can't really do in a anti-personnel version, especially if it's handmade. Unless you choose to make a shotgun, and then it's just a with extra steps.
Edit: I just reviewed some wiki articles and sabot isn't really the right term. But whatever.
They could've been great at it if the woke mob didn't cancel Samsung over their combnation smartphone battery / gunpowder substitute tech attainments just because it occasionally burned down a house by itself
AFAIK what the military has been researching are large (naval) railguns. Coilguns are a novelty with minimal utility (note that the actual principles involved in them are used in real things, but mostly for accelerating things along rail systems, not as guns or cannons), but railguns have some promise in pushing the upper limit of what artillery can do (and AFAIK what they were focused on was specifically a hybrid system that would launch a shell with conventional propellant into a railgun barrel that would then accelerate it even harder) because they can get things moving faster than gas can expand and put more force on a projectile than conventional propellant alone could without having a building sized barrel to accommodate the force.
Ultimately the project made a big fixed emplacement that could launch a projectile faster and harder than any other system, but which was both logistically infeasible due to it rapidly destroying its own barrel (a seemingly intractable problem with railguns is that at high power levels the surface of the rails oxidizes and the rails themselves can warp), and obviated by missiles largely replacing the role of artillery along with "what if we could put a single shell somewhere near a target even faster than a missile, once, and it would take an entire ship dedicated to this task" turning out to not be as useful a niche as sci-fi brained military officials thought it would be fifty years ago.

[Legendary - Success]: Schwerer Gustav, but you don't shoot from it, you shoot it.
I truncated that down a bit because it was already getting a bit too wordy, so I skipped the examples. That would be things like some roller coasters using electromagnetic launch systems over conventional chainlift hills, aircraft catapults on carriers to get them up to speed fast enough to take off, some trains use them for propulsion, etc. It's a really good way of making a big fixed system push things along quickly for definitions of "quickly" that include accelerations humans can comfortably survive, it's just not very good at making a small and portable system for launching projectiles very fast at a speed that a human on the other end of the equation wouldn't comfortably survive.
From what I know the only practical military application of coil guns would be artillery. It's quieter than conventional artillery and also produces no flash or smoke. Small arm coil guns seem hilariously inefficient unless you poison the round or something.
There's a coil shotgun on the market that has a muzzle energy of about 85 joules. For comparison an average pistol will be around 550 J. A 5.56mm rifle is around 1800 J.
Hasn't DARPA been working on something like this for decades?

There are tutorials on wikihow! But finding a disposable camera is a bitch nowadays.
You can buy a 12v DC ro 220v DC boost converter and a few 220v capacitors, that's essentially the part that you are scavenging from the camara flash.
I feel like Samsung had a grip there on leading the development of batteries that explode
Not as well as gunpowder. Its really good at exploding; even Samsung batteries are talented amateurs.

Gunpowder SUBSTITUTE?
what woke soy cuck shit is this?
you know what, agreed, time to call them Soysung exclusively from now on

To be fair if I'm launching the actual schwerer gustav at things I don't think "human that rides on it could survive" is high on the priority list
