Mount Pleasant

The modem arrived and the mount got built and the modem got plugged in and it didn't work.

The old modem got plugged in and it sort of worked, but the BOC sent me logs showing lots of reboots. So limping along we're waiting for the stuff to be sorted out and the paper work to be completed and all to be resolved and life to go back to "the day before the storm hit".

Meanwhile, Google Maps released a world-wide view of their BETA service and I started playing with the software. A whole lot of hacks had appeared, almost over night, that showed off many and varied ways that Google Maps could be used on your own web-site. With a little tweaking I came up with a quick and dirty hack.

About 48 hours after I made my first hacked up version, Google announced the Google Maps API which allows you to make official Google Maps on your site. I signed up, did the work made a nice little map and have spent the past four days banging my head against a wall trying to give it the same functionality as I already had, but using the official API. This involves me relearning JavaScript, learning XML and XSLT all meaningful subjects, just not really all that exciting when all you want to do is show a map, but you get that :)

VoIP is coming, a bigger transmitter should allow for a smaller dish, the World Solar Challenge, 2005 is nearing, there's a project with one of my colleagues in Alaska in the wind, I'm writing some nifty code to sit as a pipe between irmp3 and mpg321 to make the play list on our mp3 player no-longer repeat itself ad-nauseum and I've got cattle to feed, tractors to drive, dogs to pat and fish to treat with WheatBix meal. Frances is off picking olives after her long running transcription gig for the Australians at War Film (http://www.australiansatwarfilmarchive.gov.au/) Archive finally got completed.

Bamera

Second time around at the Station in Barmera. This time I set it up closer to the Station itself, so it had more protection from the wind. We had help unloading the beast this time, so Frances and I could rest easier, but it was still pretty stressful trying to determine if anything had been permanently damaged.

We started experimenting more with the covering of the dish. In an attempt to stream line the cover we actually setup the dish and then lifted up the mount and slid the tarpaulin underneath the feet. The only result was that it was harder to remove the tarp when we had to pack up.

When we did pack up, Frances and I were alone again, and instead of repeating the dropping disaster at Kangaroo Valley, I decided to try to see if it would be simpler to just remove the fibreglass from the frame, rather than keep it all together.

So, I unbolted the fibreglass and we loaded it into the van. That was pretty simple. Now the only problem was, what do we do with the rest? We tied it down to the side of the van and crossed our fingers. I didn't like it for many reasons, the chief one being that it was tied up overhanging the dish and if the ties or the tie points failed, all hell would break loose.

Luckily they didn't fail.

Bamera

Windy Barmera caused some stir when we installed our trusty connection, because we set it up in the court-yard of the old train station. We visited the home of the last station master and he took great interest in the goings on next to his old platform.

The technology worked just fine, we didn't use a wireless link, I cannot recall why, but ran the 80m Ethernet cable that we constructed in Crossing Falls for the first time in a non-troubleshooting role.

Setup was uneventful and our hosts took great delight in explaining to their friends that we carried the dish around to watch TV - seeing as they had one on their roof too and that's what they used theirs for. We decided that it was a little too complicated to explain that we didn't use it for TV.

Middle of Nowhere

The most memorable because of its location.

Initially the plan was to camp in Woomera, but the team changed their mind and decided to camp on the side of the road where the car stopped. Fortunately it was flat, as far as the eye could see.

By this stage the team was experienced and most of the work was completed with little effort on my part. Tuning was simple and we were on-line within an hour of arrival. The German Team also camped at the same location and shared our on-line experience.

Frances took a photo that made it to the Melbourne Herald Sun.

Coober Pedy

Living underground is interesting, but it makes for exciting conversations on your mobile phone.

Our worst race fears all happened together. First of all, we setup away from the road in a nice quiet corner of the motel. There were no obstacles, but there was a power line overhead. After trying to tune for an hour, we moved the dish and found a signal straight away. Turns out that power lines are not good for satellite signals.

So, then we were tuned and switching on the modem gave us similar symptoms to those seen in Crossing Falls and an urgent call was made to the BOC.

Seeing as I had received email every night without notification of any updates, I didn't expect that again Optus had made a change without a notification. (Not even to the BOC apparently.)

So, with me inside on the computer, an Ethernet cable running 50 meters to the dish and one of the Sungroper Team members standing outside on the mobile, relaying information, and remembering to disconnect the dish from the modem, we again re-programmed the modem to a new set of frequencies.

After 45 minutes we were up and running and all was forgiven.

The location was on the side of a hill, so I decided that some chains and pegs were in order. The next day I learnt that you do need to use a van to pull pegs from the ground and that if you do, some pins bend 90°'s before coming out of what I can only suspect was sand-stone. Suffice to say that the dish didn't move...
