Clinton Got A Blowjob

This is funny. You can buy it from his website for $2.00 if you really want...

Some scenery

I had to do a quick trip out to meet the rest of the crew who are working at the exploration camp the other afternoon. I gave them the lan cables that I had made and they gave me the ones they had that needed repairing. The sunset on the way back was quite lovely so I thought I would share a couple of the better pics here...


I even got out of the car to take this shot!



This one was taken at 110km/hr
(Hence the blur)

A couple of photos taken on the road from the exploration camp and Woomera.

Job Specs: "Part MacGiver"

And dont ask "which part" - you know what I mean!

A little background. To collect our data we require a power source in our case it is a small 12v battery for every data acquisition unit (DAU). Normally I need 2 batteries on the line here at the remote and have 2 on charge in the dogbox all day. About every third day I swap them over.
The line we are recording at the moment is the largest we have done and all spare equipment is in use. Therefore I have no spare batteries here at the remote. To charge the batteries I have a charging harness that connects from a 12V regulated power supply to the batteries. However the same 12V power supply also runs other things in the dogbox and is a hassle to remove if I wanted to take it to my room to charge the batteries overnight there.
Solution: A 12V car battery.
Problem: Not enough amps to trigger the relay for the charging circuit built into the battery box.
Agro's Solution: Remove batteries from box, use a coathanger (or trouser hanger to be specific) to connect the batteries in parallel, connect the battery charger and hope the hotel room doesn't burn down while sleeping....



Square Meals

A follow on to a post on wed July26.

Most mornings I get asked by Phil, who is 85km away at the driller's camp with the rest of our crew, how my dinner was last night.
He asks because he knows :) The rest of the crew dined at the same place as I have my dinner every night now a couple of weeks back.
Anyway, he knows that if it was on a square plate it was a fancy schmancy dinner !

At the end of the day when we are signing off Phil says" Go on, off to your "sqare" dinner.

Well every Sunday dinner comes on a square plate...

Australian Vernacular.

Ever heard the term "Dropping like flies?"

It is in common usage in Australia and I thought it referred to flies that had been squirted with DDT or some other "fly" spray.

However I have had cause to think otherwise now. This morning I opened my office (tin shed that fits on a ute) and found that the ceiling was covered in flies.
The funny thing is, the flies were asleep... There is a strong correlation of fly quantities and heat so I think their sleeping was due to the cold temperature overnight.

Anyway I thought they were dead... I touched one and it fell like a stone to the floor where it slowly came to and walked off... I tried it with several more flies and got the same result... That was when I realised they were asleep.

So maybe that is why we have "dropping like flies"

P.S. I collected all the flies from the ceiling (very easy to do when they are asleep LOL) and disposed of them... however now that the day has warmed up I have a new population of them moved in ...

MIMdas - A little about what we do out here in the middle of nowhere...



The system is based upon single channel distributed acquisition units (DAU’s) that collect 19/24 bits (depending on
sampling frequency) of non-aliased linear data with a bandwidth of 0 - 20 kHz. This data is relayed to central
recording unit (CRU) in a recording truck, via local area network (LAN) cables. Each distributed acquisition box is
accurately synchronized and the data buffered in each unit is transmitted to the CRU at the end of each event. The
acquisition software allows interrogation of each box and can display raw data as it arrives. The data is processed on
site and field plots produced. One value of recording and storing complete time-series data is that it allows reprocessing
at later times. For controlled source surveys at least one channel is devoted to accurately monitoring the
input current from the transmitting source. This current data is then used to deconvolve the input data and
compensate for non-ideal transmitted waveforms.
The distributed system avoids multiplicity of cables attached to sensors and the inherent capacitative coupling
problems. It also means expandability as the number of units/sensors is limited only by logistics, andthe number of
available DAU’s. The data from each channel is collected simultaneously which offers considerable noise
cancellation benefits. The time series data allows simple signal processing procedures to remove cultural noise,
which when combined with selective stacking routines and other remote reference noise cancellation schemes
produces very high quality data. Considerable area or line kilometers of quality data can be captured rapidly.

I know I said business as usual but...

I got a little busy :) I have been checking out www.bucketty.org it is a growing site that one.

Anyway, here's a pic...


Not many trees arund here

We took an unexpected break.

We were waiting for some equipment to come from South America but as it got delayed we went home for a few days.

So there you have the explanation for the lack of posts recently :)

Things should be back to semi-normal for the next 3 weeks.

Cheers,
Agro
