(hackaday.com)
This is a most excellent place for technology news and articles.
I like the idea of automatically fastening zips in places with limited access (like the tent example in the article), but unless the failure rate is very low, you'd always need a backup fastening technique on hand
and unfortunately for them a large number of the backup applications consist entirely of “attach a string to it”
