Matt outfitted his headgear with some quick-n-dirty AC –
I was bored one day at NYCR and started playing with my rising collections of motors.
Ended up stuffing an 18v motor into my bike helmet and putting two 9vs in series on it. Runs awesome. Surprisingly effective as a cooling apparatus and even more surprisingly effective as a fume buffer.
Probably not very safe in an accident though =P
Consider it an early prototype – fume buffering == quite welcome for urban usage. See the original photo on Flickr.
