The accelerometer system is based on the system developed for Project Txoom], so the [[Cerf Notes might be useful if things deviate too far from the script.
- check System preferences > Network > Location is set to "sensors // no inet" - open 'terminal' - type sudo -s - enter password - type /usr/libexec/bootpd -D - connect the sensor to the ceed (black box) - check ethernet cable is connected to the laptop - connect the power to the ceed - wait - you can check the connection by typing tail -f /var/log/system.log and waiting for something like bootpd: ACK sent familiar. 10.0.0.2 pktsize 300 the nu,ber starting with 10.0.0 will be the ip of the ceed - type ctrl-c to exit - connect to the ceed by typing ssh firstname.lastname@example.org (the password is rootme) - follow the sensor setup instructions from here ... . - type insmod adxl.o - type ./operate -h 10.0.0.1 (note: this only works when something is listening ie; oz in max)
