Since nuclear reactors emit neutrinos as well, there are experiments measuring the neutrino output at two different locations from a commercial power plant and compare the flux of neutrinos taking the mixing into account (as well as all the other sources, of course).
Actually, I did an internship after school with one of the groups: https://www.mpi-hd.mpg.de/lin/research_dc.en.html
After several tries, I just gave mine away, for the same reasons. There are so many boards that are a pleasure to work with, but this one was not worth the hassle.
I can recommend the replacement, a PC engines board with four Gigabit Lan ports running OpenWRT.
