Last week I was lucky enough to go out sailing on the Tall Ship James Craig. We sailed from Sydney up to Broken Bay, spent most of the week up there. Then sailed back down on Thursday with some great weather and managing to get some significant sail set.
Here are some pictures from the trip.
Fore Course and Topsails in their gear ready to help us up to Broken Bay.
The Main watch only had 2 sails to look after on the way up.
The sails on the Fore Mast set and drawing on the way up.
Just around the corner from where we anchored.
Everything furled and packed away for the night.
It's difficult to get a good picture of the moon with a phone.
Just before the sun came up on Tuesday. I was lucky enough to get the last anchor watch.
Looking up river to the railway bridge.
That's a lot of water.
That's now a lot of sky. It was pretty rolly until about lunch on Tuesday.
Back on the anchor Tuesday afternoon.
No moon on Wednesday Morning.
Looking out at the big blue wet thing.
Still at anchor. That looks a lot closer from deck than it does from the chartplotter.
Had a couple of rainy patches on Wednesday.
A bit clearer now.
Perfect timing. Just after coming down from the royal yard.
Thursday morning. Going sailing out there.
We actually managed to sail of the anchor on Thursday. Here is the full Fore Stack set.
We did get a little bit of rain, however it wasn't too heavy to ruin the great sailing.
Back in Rose Bay with the Anchor Lights set.
Not too bad of a morning.
This is where I slept for the trip.
The wind was starting to get up a little before we left Rose Bay.
One of my duties was the anchor locker. This means that as we raise the anchor 4 of us would flake out the chain so it is nice and even so it can't topple over and get a knot in it as we try to drop the anchor next. This is what it looked like as we were anchored.
Here it is filled up with the anchor retrived.
This is the bottom of the hawse pipe where the chain comes down into the locker. You can just see a hand in the background. They are probably about a meter behind the front wall of the locker.
We've managed to fill up all of the hard drive space I put in the NAS (Jerry) Thankfully it hasn't been too critical and we have been able to continue as normal basically without noticing that we can't store anything more on there.
However this is something that does need to be fixed. So I bought some more hard drives. I'm using Western Digital Greens from ebay with the head park adjusted with WDIDLE3 to extend their life. I know these are not ideal drives for use in a NAS, but they are cheap and the RAID 6 configuration means that I have time for a new drive to arrive if one dies.
Here I am setting the head park idle time to reduce the number of head parks which can wear out these green drives quite quickly as the default time is very short. It makes sense when you think they are designed for absolute minimum power consumption, but it can be a problem.
I don't have a computer set up as a test bench for doing stuff like this so I have to pull some cables out of my normal use desktop.It's not too bad to have to do. But all the same having the space for a dedicated machine with swappable drive bays for this sort of thing would be nice.
Make sure you label your CD's!!! I had a dozen or so un-labeled disks I had to go through to find my boot CD. They have now all been labeled and put in a sensible spot.
The new drives are in. This means that I just need to expand the array and it will all be done, right? Not quite. Turns out that you can't expand an array using a p400 RAID controller if the battery backup for the cache is busted. Thankfully these parts can be had for only a few dollars from ebay.
The replacement part.
Drag the whole mess out.
Apparently orange = bad.
And here we have it. The new part in and all ready to go. It was a pretty simple replacement however there were one or two parts that had to be jiggled the right way to come free.
Here we are, expanding the array. Unfortunately I think the whole data set has to go through the cache on the card which is only 256 mb or thereabouts. The array is approximately doubling to about 4.5 tb which is a lot to have to shift through 256 mb. I'm expecting this should be finished copying by the end of the weekend but that is pretty much a guess.
Once the RAID card has expanded the drive I think I will need to expand the filesystem so I will do a writeup on that because I will need to remember as well.
Last weekend I fired up the oil burner again. This time I prepared a reasonable amount of fuel for pre-heating. I even tried to light it without accelerants. Unfortunately everything was wet and the kerosene was so close to hand. So I did cheat a little.
Here I am, with the pile of wood just starting things happening.
Maybe a little quick. But I didn't quite kill it.
Starting to burn down nicely.
Starting to get a bit excited with a little oil and air added.
I managed to turn the oil down too far without realizing it as the fire got a little too smokey. It was taking off but it didn't feel quite right so I fiddle with the oil and lo and behold. It starts to take off.
Lets see if I can make stuff hot with it.
A little hard to see here, but the bar certainly did get forging hot.
Lets see if we can make something a little more substantial properly hot.
The end of the camshaft needed a little support to keep it in the hottest zone.
While it probably would've looked much better at night it did get hot enough to move some metal around a little. I think the white coating is fine ash from the wood getting blown around by the blast from the burner and coating everything.
Just before I shut it down.
And here we are cooling down. When I came back an hour or 2 later there was still a fair bit of heat radiating out from the bricks. They were definately hotter than you would want to touch.
Here is a quick shot of me pre-heating the fire pit before anything got too exciting. Here we are with the burner running and adjusting the air/oil mix a little.
I'm hoping to get some more shots of interesting stuff getting done this weekend so keep an eye out for those next week.
Paying for a good tool or a part can be a bit offputting as the initial expense seems to be much higher. However cheaping out and getting something that might not work properly will most likely be more expensive in the long run. I have had that idea highlighted for me while I was setting up a KVM switch so that I can run both the beaglebone (Mill) and the 386 (Lathe) through the same monitor.
These are the parts I tried to use. I got the keypad, kvm and an extra VGA cable from The Junktion for $5. All of them seem to work and are in good condition and would probably work in a more normal situation.
This is the KVM switch. It's better than the last ones I had because it gets all of it's power from the computers. However it's a bit different in that it needs a set of keys to be pressed on the keyboard to change the controlling computer. I don't use scroll lock much, particularly on these computers so that won't be a problem.
The stack of adapters. The fan I had wasn't working so this was going to be fine for a test. I do have an HDMI to VGA adapter somewhere that will let me have a fan and get video out; but I can't find it at the moment so I'll make do.
And here we have the rat's nest. I don't do a lot of cable management because I am changing things so often that having a strict management system would get more in the way then a mess like this. Regarding noise and crosstalk between the cables, anything back here with a signal is shielded and the only thing with significant power other than the mains cables is the drive to the stepper motors which is reasonably heavily shielded. So I don't think noise will be a problem and I certainly haven't had any issues yet.
With everything plugged in I powered it all on and... It... didn't work. It would display the screen from the 386 but I could not change it to display from the beaglebone. I think what has happenend is the KVM switch is expecting to be plugged into PS/2 ports (That's why it has them I guess) but I am plugging it through an adapter into an old style keyboard connector and that's it. No mice or keyboard from the Beaglebone.
I think this is causing it to run out of power and just not work properly.
To fix this I am doing what I should have done in the first place and buying a cheapy from ebay that is completely passive. From the picture of it's guts I saw it is very basic which will be perfect for this as then there is less chance it will not work.
So sometimes it pays to just buy the right thing in the first place. But for a hobby, while it can be frustrating and demoralizing it usually isn't too bad. In a business situation however it can cause major problems.
