Data repository for Arduino-based Ballistic Chronograph. This repository is no longer being updated since release of the MK2. For the MK2, please see https://github.com/td0g/ballistic_chronograph_mk2/

The Sensor Emitter Schematic is a complete electrical diagram for the ballistic chronograph.

The BOM is only for the electronics.

The drawings include a perfboard layout and a drawing of the sensors and emitters. Notice the spacing of the sensors and emitters - this particular configuration is the best optimization using only 8 sensors and 8 emitters.

I'm maintaining updated firmware at https://github.com/td0g/ballistic_chronograph_mk2/tree/master/Firmware. Please check it out for a few flavours of chronograph firmware!
