people build working fusion reactors in their garages

A fusor is basically a spherical grid inside a vacuum chamber with a bit of deuterium and tens of kilovolts. It genuinely fuses atoms and you can detect the neutrons. It also uses vastly more power than it makes, which is fine because the point is doing it. Among hobbyists, detecting neutrons is the bar for having actually done it.
