Being able to burn things at a distance has a LOT of applications if you get creative with it. For example, if there's any adversary materiel that would be better if it were on fire, and you'd rather not get too close to it. People should keep this in mind more I think.

Coilguns and railguns (electromagnetic launchers) are an interesting area of technology that has much potential for small-arms scale designs. For example, several hobbyist projects shown on the internet (see below) demonstrate kinetic energies up to 50 J (36 ft-lb) and muzzle energies around 120 m/s (393 ft/s). That's way short of a firearm, but actually within the realm of bows or crossbows, as well as low-velocity launchers like flare launchers. Coilguns and railguns aren't really electrically complicated either, since they're directly analogous to some common types of rotary electric motors in how they produce a force or torque. Hopefully people find these interesting.

This channel has some good videos on civilian-made UAS, with a particular focus on introducing them to the 3d2a sort of community because any sort of munitions delivery or guidance systems are essential to any combatant force now.

Not my video, but this is a pretty impressive gun that uses butane-air mixture to shoot various projectiles like steel balls or rods, and it's autoloading and electronically controlled. Nominally it is a "potato gun" but really it doesnt shoot potatos (maybe it could shoot a french fry though)
