Puzzling fieldwork

Sailor Cat needs to bring a wolf, a goat, and a cabbage across the river.
The boat is tiny and can only carry one passenger at a time.
If he leaves the wolf and the goat alone together, the wolf will eat the goat.
If he leaves the goat and the cabbage alone together, the goat will eat the cabbage.
How can he bring all three safely across the river?

This is a fun little puzzle, but its analogous logistical fieldwork quandary we are dealing with. We have 12 stations on 4 islands. Each station has a dead battery and we need to replace the dead batteries with recharged batteries. In order to charge a battery, we need to leave it for 12+ hours at a hotel/port and can only charge 1 battery at a time. Each station has a different travel time from each port. How do we design 4 separate circuit diagrams, one per island, to visit each station and swap its dead battery for a charged battery?

Goodbye Dili! For now?

6 stations done, 14 to go! This past week I've been touring around Timor Leste with Atoy - the lead mechanic for IPG, an awesome driver, and a pretty fun guy, even if we do have a bit of a language barrier. Now I'm preparing to fly to the Oecussi station Saturday morning, where I'll meet Teo and Atoy. Its a complicated station because Oecussi is separated from Dili by Indonesian land and visas are complicated. But once we get this station done, I'm done with Timor Leste for this trip. Its an interesting country and really makes me think about history and infrastructure and society. It'd really be great if everyone in the more developed world had a chance to visit here for perspective. But I think that window may be closing soon because I think this country is really developing quite quickly. For instance, I've been spending the last couple days in Dili working on trying to figure out how to telemeter some seismic stations. They're almost there and just need a little help to configure dataloggers to send data through the cellular network to their office in Dili.

Rob and Nova, back for a service run

Hi, Rob here. I'm back in Dili for a service run of our stations in Timor Leste and then to service some new stations from Australia. Nova and I were on a flight together from Seoul to Bali, but we split so she could go visit family for a while in Jakarta while I take care of Timor Leste. We'll meet up soon to do a few stations in Indonesia.

Nothing too much to report. I've serviced our station in Dare and in Atauro and both were working well. Now I'm taking some downtime before preparing for a 4 station run around eastern Timor Leste with Atouy before coming back for Maliana and Oceussi stations.

And the after picture...

I forget what this is called, but the yellow, spiced rice is served in this wrap made of palm leaves. Very tasty.

Yes, this is a picture looking out on the clearest blue sea from a little island paradise.
