I just played a little bit with APRS igate on Linux. There are some igate software available on Linux but the most supported package (javAPRESSrvr) is not available today because of an error on Yahoogroups where the files are hosted.

Therefore I installed xastir from Sourceforge and connected the the local running instance with the APRS-IS network. Now DM1AS is visible on FINDU.

Nice side effect on this, the server generates an Google Maps page every 5 minutes with APRS stations around my home. Maybe tomorrow I connect my radio to the igate and there will be more local stations available.

So far you can see the map here:http://tinyurl.com/nacc5k

I spend this rainy day working on an old project and I am happy to announce its 99.8% finished. Now I have a nice Atmel Board screwed to the wall with an ethernet port. Nice little project where you can access measurement values and digital I/Os via normal http access. For now I have 3 temperature sensors running. One outside, one on the ceiling and one on the floor of my office. Idea is to control a fan when the temperature between the ceiling and the floor is to hight. I have this problem specially in winter times when the heater is on. Next week I will attach a light sensor as well. For now you can find all the measurements on pachube feed 1303. For example here is the outside temperature sensor. Time is in utc.

My blog will be offline on sunday for some time because I will reinstall the server with new HD and Ubuntu 9.04.

Thanks to Oli (@EOLUS) I am now Beta Tester of Pachube. Cool Web 2.0 Service for Real Time Data exchange. People are streaming their measurement data with geographical informations in CSV or EEML XML format and can exchange their data.

I am now streaming my server temperature just for testing. Check out

Hope more will follow soon.

Its very easy to send your data from linux. For example with curl and csv:

/usr/bin/curl -X PUT -H “X-PachubeApiKey: abc123″ -d “`/bin/cat  /proc/acpi/thermal_zone/THRM/temperature | /usr/bin/cut -c 26-27`,” http://www.pachube.com/api/1287.csv

Important is your Pachube key in the header of the PUT request. And your feed ID. With this example I am catching the acpi CPU temp and send them to Pachube.
