I met a very interesting product designer from the Royal College of Art the other day who has started a hardware startup meetup group at: http://www.meetup.com/Hardware_Startup_Lab/
Their first event is on the 14th of November and they already have a strong list of people attending. Lets join in and make this a great event and meetup. They have 3 speakers at this first event with networking over drinks during and after.
Come along and join in the fun.
