I think the original post is just an advertising prank and maybe a virus spreading prank at that.
I noticed also that the second pdf does not download so why does he leave it there ?
All the references just give you the same advertising speel and nothing is said of any Arduino connection
I think his posts should be removed but leave the soda pop posts .
I use them all the time for fruit flys and very effective they are even with a splash of beer in them
