Many cameras these days have optional remotes that allow the shutter release to be triggered wirelessly. Despite this, [Foaly] desired more range, and more options for dealing with several cameras at once. As you’d expect, hacking ensued.

The system goes by the name of Silver, and is modular in nature. Each Silver module packs a transmitter and receiver, and can send and receive trigger orders to any other module in range. This allows a module to be used to trigger a camera, or be used as a remote to control other modules. There’s even a PC interface program that controls modules over USB.

Modules are also capable of sharing configuration changes with other modules in the field, making it easy to control a large battery of cameras without having to manually run around changing settings on each one. Oh, and it can run as a basic intervalometer too.

LoRa is used for wireless communications between modules, giving them excellent range. [Foaly] successfully used the remotes at ranges over 500 meters without any dropouts, capturing some great model rocket takeoffs in the process.

Silver is a highly robust project that should do everything the average photographer could ever possibly need, and probably a good deal more. Firmware and board files are available for those eager to make their own.

We’ve seen several very impressive camera augmentations entered into the 2019 Hackaday Prize, from ultra high-speed LED flash modules to highly flexible automatic trigger systems.
