README.mdLightning Trigger
Features
-
Lightning Triggering - By using a photo transistor, lightning strikes are detected and triggers the camera at the same instant.
-
Sound Triggering - Sound triggering mode is used to capture sound events such as water droplets, breaking glass, and fireworks.
-
Timelapse- Calculates the number of photos for a given length timelapse, given the photo duration, interval, and total timelapse length before taking all the required photos.
Currently has support for two triggering outputs (can trigger two devices at once) with an additional two outputs being added in the next revision.
Control is through an Android app using the HM-11 Bluetooth module.
Power is from a li-po battery and is charged using an onboard li-po charger.

Questions
How big is the Lightningtrigger PCB?
It measures 42.9 × 70.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lightningtrigger use?
72 parts, built around the ATMEGA328P-AU, MCP6001OB, TLP291-4 and AP9211. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lightningtrigger KiCad files?
From the kanestoboi/lightningtrigger repository on GitHub, at the commit this page was made from: the board is Hardware/lightning trigger Rev 3/lightning trigger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lightningtrigger design in my own project?
Its repository states no licence, so its author keeps all rights: ask kanestoboi before reusing the design.
