The Deimos is an ordnance-dropping system designed with a universal mount.
It can be used with arbitrary drone platforms including many fixed-wing designs and most common quadcopter bodies (both off-the-shelf commercial stuff like mainstream DJI drones and fully DIY stuff).
This file pack includes two distinct designs - a single-dropper (the Deimos) and a dual-dropper (the Phobos).
The single dropper carries a single triggerable payload; the dual dropper carries two, triggered independently.
Both are designed to be trivial to build using easy to acquire parts anywhere in the world.
Both versions can be configured to trigger using either (1) the "5v System" with any pin on the flight controller that can be turned on/off or (2) the "Photocell System" with a photoresistor.
