anybody got some Solaris/Sparc media for an old Sun Ultra 10 ?
Was somebody without a power source.
AllSurplus has some in Arizona.

I have 2 or three pallets of gear inbound. Maybe I should sit this one out...
Just got a message from our electricity supplier: price going up from 90 to 160 euros per month.

Yesterday I spot-weldet a banana contact tab of my differential probe against a grounded PSU casing with 230V AC.
The welding is excellent.
This little bit of accidental dissimilar metal welding got me thinking.
In electronics equipment construction I occasionally come across things that could be best done with a little bit of resistance welding of dissimilar metals. Things that come to mind include:
- Welding a grounding strap (tinned copper type) to the inside of the lid of an aluminium case.
- (Extreme case) Welding the bottom of a stud/bit of all-thread to the inside of a case for a fixing/grounding point.
- Welding a spade lug to a case for a ground bonding point.
- Tacking metal mesh (SS?) to the inside of a cooling grille (Al, Fe?) - both for ground continuity and even possibly all the mechanical support required.
That covers a range of oomph from "Probably needs some real welly and a proper discharge welder" for a stud you actually needed to have some mechanical strength to jobs you might even consider doing with a 'toy' like the capacitor discharge welders used to stick nickel strips on batteries (tacking mesh around a grille opening).
Obviously using fully fledged professional pulse resistance welders designed for the job is cheating (and expensive) but improvising with cheap automotive spot welders and battery tab welders might be an interesting area to explore.
Has anybody done any improvisations in this area? Any battle stories, bodges that turned out actually good, experiments that failed disastrously?
[Cue stories from SeanB of exploits, in typical South Eifrican style, with an infeasibly large stick welding supply and some innocent victim piece of equipment. ]
Anyway, couldn't resist. Tear down photos.
It's all there. The fan is all gummed up and will need cleaning/lube. Not unexpected.
Component side. A thing of beauty and easy access. Good thing because it is full of electrolytics.
This multi-multi range switch deck is jammed tight. Tried with a pair of vise grips and no good expect buggering up the shaft. Will apply lube and let it sit for a day or two.
Unlike this guy, who was not properly dressed :

The surprising part is that it is not even the first time ...

I might have something. Not that it is a sensible thing to put such old SunOS releases near a well-connected network.

I am still out there lurking. Still unboxing/sorting/organizing the lab stuff. Getting there...
In // I am working on the bedroom. Just finished fitting the parquet, glued. Now need to oil it. Waiting for the oil to com in, then need to find a company that can rent me the machine to apply it properly....

You know teh drill...
"Yeah, we can get that for ya; but it'll take 3 weeks and cost 3 times as much..." )
"Yeah, if I wanted it made with crap, I'd hire one of your affiliate contractors to do the job."

Got today an order from China of some LiPo battery packs.
The packaging was creative and did come with an explanation.
No warning signs or stickers on the outside of the air cushion envelope.
I am not sure what to make of it.

Cerebus' standard warning about drying oilsThis is folk knowledge that tends to get passed from hand to hand but for some reason is never printed as a warning on cans of drying oils used for oiling wood.(If you already know this please ignore, but I always post this in any discussion of drying oils becuase some people don't know this, and knowing it may save a life.)
Drying oils such as Danish Oil, Tung Oil, Linseed Oil and the like can spontaneously catch fire. Rags that have been used to apply drying oils, and that still have drying oils left on them can catch fire just from being left in the open air.
The mechanism is that the increased surface area of the oil exposed to air by being soaked into a rag causes a lot of the oil to 'dry' at once. This generates heat. The heat causes the oil to 'dry' (oxidise) faster. This makes more heat, which makes the oil dry faster - you know how this one goes, it's the classic chain reaction. The heat, combined with the insulating effect of the rag's cloth can be enough to cause the rag to catch fire.
The same applies to any material such as newspaper or paper towels used to mop up spills of drying oils or used to remove excess oil from workpieces.
When using drying oils on rags and cloths always handle the rags/cloths appropriately when you have finished with them. Either thoroughly wash out rags before disposal or storage, or soak them in water and place them inside an airtight bag or container. Do not leave rags and cloths unattended for long periods (e.g. over lunch) without taking appropriate precautions to prevent them possibly catching fire, or putting them somewhere that a possible fire will not present a hazard and will be contained.
