Movement tracker with accelerometer

This device so called Station Master is small key ring sized device which tracks movement in the train. As train goes, device vibrates, but when train stops, it generates alarm after predefined number of stops. So you don’t miss your station. Device is based on Atiny13 microcontroller and MMA7260 3 axis accelerometer from Freescale. Alarm is generated by cell phone vibro motor.

Project files include schematic and assembly program which is very compact due to smart program optimisation – especially filter part, where movement signal is detected from noise pattern.
