[Noisebridge-discuss] canon camera swap for spacebridge balloon launch?

[Mikolaj Habryn]

Hmm - there's a 3.5mm jack hidden under a flap, along with mini-USB.
Can I just plug in a mono plug and try shorting the pins together to
see if it's a trigger jack (as opposed to audio)? Or does it require
something more complex to trigger it?
