- Project connects two computers via lasers using Linux tun network devices.
- Uses USB-UART cables connected to ATtiny85 microcontrollers with lasers and phototransistors.
- Originally planned for 38kHz IR sensors but switched to phototransistors due to reliability issues.
- Data transfer achieved at 4800 baud, with SSH connections taking about a minute.
- Safety measures included using laser safety goggles.
- Each computer runs a relay program to manage packet transfer between tun0 and UART.
- Source code and more details available on GitHub.
