Probably lied about his health, given his age.

try this.

war is only 'bad' when your side is losing.

The closest I have come to this scenario is in a car and I hope it stays that way. At about 3:31 into the video it looks like he nearly lost it, 90° bank angle or very close.

What does the compasss read when placed on the ground away from any hangars and aeroplanes. You need to establish if the problem is internal or external (to the compass) .

one might wonder if this is real or not....

At my age, if somebody tried to sue me, I'd tie them up with piano wire and toss them in a river then spend the rest of my days playing cards and watching Foxtel as a guest of her Majesty.

Vineyards - lots of posts and wire.

Wow! I have been accused of 'thrashing' the joystick to death but this guy runs rings around me.

Never heard of Phidgets before but it looks good. The 'further problem' is the need to isolate the circuit when doing a read, but you know about that. I haven't tried it yet. Went for a blast this morning (Sunday) before the gliders got active, quite nice. My beer never lasts long enough to go flat!

Why do the "Cheesemakers" get special attention? They mean all producers of dairy products, cheesmakers is just an expression...

Okay, after a short break to do other things, I completed the prototype EGT monitor. Because the thermocouples are fed into differential amps, they cannot be electrically connected together as they would be when all attached to the aircraft engine. (We have the wrong type of thermocouple interface board?). The solution was to switch a thermocouple in, do a read, then move onto the next thermocouple using relays. This works well, each thermocouple sensing the temperature as expected (100°C in boiling water). There is a further problem, I wonder who can guess what it is. I shall work on that shortly...

Our newspapers have become so trashy and amateurish it's a joke. And the spelling and grammar is pathetic. Let's hope our fellow pilot at Cobdogla comes out of this okay...

The rotary switch was only to test a theory. If the error is small (millivolts or even several volts, who cares considering we will be looking at maybe 600°C and the error would be the same on all four probes. Thanks for your comments...

Here's an idea (for those still listening). I could use four solid state relays to switch the input to each probe in turn and only need one of the MAX31855 channels. We know switching works because we did it with a ordinary hand cranked rotary switch.

The 3 volts versus the 5 volts is a big thing, okay, please explain how it relates to the problem I posted. If I have it wrong, how come all works as well as it does? What is there in the code posted by Kyle that may fix the problem? I'm the learner here, not the teacher. If my posts offend, throw money on my roof, I hate that....

Let's not digress; unless you think the 3 or 5 volt thing is causing the problem.

here's the code.... /* EGT-monitor-v4 Version 4.0 This version extends version 3.0 by using all the theromcouple lines and no serial port. WORK IN PROGRESS!!!

Okay, we have an Arduino reading four EGT probes via a four channel MAX31855 board. The temperature on each probe is being displayed as expected but when the probes are immersed in a saucepan of hot water, all four readings drop to zero but of any one probe is in the water it reads as expected (proving the water is not shorting out the probe). If the probe cables are touching those probes read zero. So, are YOU familiar with this and how did you fix the problem. I have a few ideas but would like YOURS first.

Man I am dim, I simple don't get this!

I record audio using a small digital audio recorder. Plugged into the passengers headset socket via a resistor network (10K and 1K). Works well. I then combine the audio with my video during the editing stage. I use Sony Vegas 12 for video editing. Only pilot and radio traffic recorded, no engine etc. The engine sound is recorded on the video recorder and I can turn that down. To align the audio with the video I use the distinct click that occurs when letting go of the PTT and watching the LED on the dash.

I sometimes think these mandatory inspections are a money spinner and cause more problems than they prevent. However, that's just a thought and I may not be thinking straight because of the extreme heat.

Twice I have flown to Kadina SA and both times the wind was flat out and 90° across the runway. I had a go the first time but it was pretty rough so I chickened out a came back home. The second time I didn't bother as the first time was still fresh in my memory. I also prefer cross-winds from the left, dunno why...

Doesn't work:oops:

It's when they get it wrong and you're dragged off screaming and naked into the night after being accused of some heinous internet crime you never committed.
