Daytripper
Daytripper is a programmable laser security controller and motion detector that functions as a hardware trigger for operating system actions. It is a hardware and software system designed to detect physical intrusions via laser beams to trigger automated system responses.
The system distinguishes itself through its ability to translate physical laser interruptions into software actions, such as executing keyboard shortcuts, running scripts, or triggering system commands. It also supports hardware-level integration, allowing the device to send high-voltage pulses through dedicated pins to activate external electronic circuits.
The project covers a range of capabilities including distance-window filtering to ignore movements outside a designated area and sensitivity tuning to balance detection speed with battery consumption. It includes support for multi-device synchronization between transmitters and receivers, as well as USB-based firmware updates via a bootloader mode.

- Sensor-to-Software Automation - Connects physical motion sensors to a computer to execute software commands or activate external electronic circuits.
- External Signal Triggering - Sends a signal to a computer to hide windows or execute a custom script when a laser beam is interrupted.
- HID Shortcut Emulation - Simulates keyboard shortcuts to launch applications or execute system commands on a connected computer.
- OS Command Triggering - Executes predefined computer commands like locking the workstation or minimizing windows whenever a tripwire is triggered.
- System Action Execution - Sends keyboard shortcuts to launch applications or run scripts when a tripwire event is detected.
- Physical Intrusion Detection - Monitors a physical path using laser transmitters and receivers to identify unauthorized movement.
- Sampling Rate Controllers - Adjusts sensor refresh and sampling rates to balance detection speed against battery power consumption.
- Sensor Range Filtering - The Tripwire system sets a specific distance window to ignore movements that occur outside of a designated physical area.
