Im not sure if this is in the right section as its to with mechanical things but is used in aerial photography and atmospheric circles.
You have your platform attached to its balloon and you release them into the heavens but you have no predetermined release mechanism so it thing will go up and up and up and then more than likely plummit, tumble, breakup and splat. Poor platform it was only young.
Ive gone through some high altitude balloon setups only to find the release mechanism is non existant or unexplained. Here people are recommending servo driven systems but no one gives any details, pictures or diagrams. Rocketry us explosive bolts or CO2 which is a little OTT (apart from being really cool). I have found a blokes website that give some arduino based triggers using nichrome wire and some watch batteries which seems to be a pretty pimping idea given mass restrictions but I cannot be the only one thinking about this sort of thing.
What is your release mechanism?
If you do not have one, what would yours be if you did?
I'm looking for any idea really. A repository of ideas for this so myslef and others can expand upon this for future schemes
