someone stole audiomoth in Finland, an electronic circuit meant to record bats and store the audio recordings on a low power memory card, the whole system is powered by battery that last 30 days if lucky>there is constant recording: it starts to record at night (a light sensor tells the CPU when its night instead of day, it doesnt send or download any information to internet) and the device records audio 8 hour straight, creating many 15 minute long record files (its reasonable to create 15 minute clips, one 8 hour clip would carry the risk that battery runs out before saving that one big file onto the memory card of course this would be a problem only once battery is really starting to run out, around 20th day or later)>it records only audio that is in the range that bats can make: 1000 hz to 120 000 hz so it omits any data that is lower than 1000 hz (like humans driving around with a blasting bass on a car)>it is installed ontop of a night lamp post or some other suitably tall place, a tree is good tooit was stolen in Forssa city where is now bat research ongoingit would be hard to resell this device on an auction, its usage for other things than bat research is limitedhttps://yle.fi/a/74-20247090?origin=rss
it might catch some Ebonics now which is a great opportunity to shift foreign language study
