Software on the bicycle

Existing software

• gpsd
• Linux parallel port control
• wpa_supplicant
• waproamd
• nstx
• postgis
• [Aware|http://aware.uiah.fi/ Aware] contextualized media publishing platform

gpsd

we run it like this: ./gpsd -p /dev/ttyS0 -d gnssip.ing.uniroma1.it it supports dgps over internet, but this only works a short time after restarting the daemon. strange...

media recording

atm, we know that: capturing video with sound from the webcam using streamer from xawtv works. capturing at 15fps QCIF- 176x144px. encoding MJPEG, container AVI. file size is apprx. 2.4Mb/min

Custom software

logging:

FridaLogger page collects these bits

log synching.

what is the best transfer from bike to internet? for now we are using a combination of rsync and db-link. what about mail or aware? pg-dump?

control panel tools for parallel port

small commands written in C using parapin. download the source: parapin-0.96-frida.tar.gz

• turn leds 1-4 on and off with: frida-set-led NUMBER STATE
• read switch positions and button event with: frida-read-panel

roaming selection script

want to use collected test results and the current location to optimize frida's choice of network. so far this remains unimplemented, partly because it might not be necessary.
