Self Opening Clip with time delay of 2-3 mins Answered
This is my first post, so I apologise in advance if I've selected the wrong category for the post.
I have an idea... I have a quad-copter at home that I'd like to attach a small light weight item and have it self release/open after 2-3mins. Ideally, either a small springloaded clip based on the rough image below or something similar, that is self opening after a selected timeframe, even after 1-2mins, or alternatively, a small lightweight mechanism that does the same thing. I've searched everywhere and can't find anything even close; lots of small clips, hook, latches, but nothing that 'self-opens', which is the most important spec.
I can add a new RC servo and swinging arm and operate the release by remote, but I want to avoid it if there's a simple solution out there.
Appreciate any help if someone has seen something out there?
