This weekend is the Spa 24 Hour, for which I would like to point out that we have a local team ( Lago ) in the Gold section ( ProAm, effectively GT3 class ) and to date the only Lamborgini in the field. Not to mention a few other Aussies/NZ : Craig Lowndes, Shane Van Gisbergen.

Cheers, Mike.

If I've read those links correctly : the strain relief boots will help to prevent the cable's wires being pulled out of the cable terminator ( by not being held merely by the copper barbs that pierce the individual wires upon crimping ) :



.... but does not prevent the terminator falling out of the RJ45 jack if the little detente piece snaps.

Cheers, Mike.

( edit ) I mean this is like having really high quality tyres fitted to a car, but only using $1 bolts to keep them attached to the car ! A wheel bouncing off into a paddock doesn't enhance the vehicle's road adhesion! :-)

( edit ) Ah, now there are these sleeves/boots :



... which I have used but the detentes don't always fit inside the little hemispherical 'hood', and usually this sleeve prevents the detente from sticking out enough to catch the lip on the RJ45 jack. There ! I have expressed my displeasure most precisely now .... :-)

I bought a small cable tester and we test every cable after he builds it for me. Years ago I bought a 1000 foot box of cat5 cable on ebay and have loaned it out to everyone, yet I still have 1/4 of the box left! At 40 bucks it was a VERY good buy!! One of my friends even wired his single story 3 bedroom home with it, he still lives there and loves it. He may have even let his son use it on his own home, but I wouldn't care even if he had told me.

Same gig here. I've got a 300m box of CAT5, more than 1/2 left, and do my own cable assembly. In thinking of speeds remember the connections! A little loosening may slow a connection without breaking it. Not all the male terminators & female receptors match very well in milling and the wee detente tag on the cable termination - the plastic bit with the notch that is supposed to spring out a tad and so catch the lip - is renowned for being crap and breaking etc ( that has always annoyed me intensely ).



... so specifically the copper contacts won't always meet with sufficient area of overlap and thus the capacitance especially will vary. Thus the end impedance won't match specifications and reflections/losses etc arise, but always in the direction of reducing signal rates by confounding valid voltage levels.

Cheers, Mike.

( edit ) Note to assemblers : It's the orange/orange&white pair that you have to trim slightly longer because, as the diagram indicates, you have to move just that bit extra to the sides to bring them in line with the correction termination slots. Also if you don't have a good dedicated crimping tool ( for an RJ45 ) you are insane to try any of this .... :-)

( edit ) Whoops, I should qualify that : the colors and which are swapped etc depend upon the setup/convention/usage ( confusing ), though any router built this millennium should cope with variants by sensing upon connection.

( edit ) My explanation may sound odd because one doesn't normally think of a metallic wire as a waveguide. But indeed it is ! That's exactly how AC power is transmitted by push-me-pull-you without any given electron necessarily traversing the distance to be spanned. If one looks at the very high voltage transmission lines, say 1+ Megavolts, they are often arranged in groups of four with suitable spacers to prevent shorts. This makes any radiation of quadrupolar pattern and thus quite suppressed.

Bernie Made-Off. The clue was in the name all along.

Ah, a Ferrari Spider. If you have to ask 'how much?' then you can't afford it. :-)

That is quite a rapid onslaught of Werewolf Sightings ..... I'm getting worried !

Bill



Cheers, Mike.

( edit )
Between 1520 and 1630 about 30,000 people were reported to French authorities for being werewolves.
Err .... just yesterday ? That's quite a few for a mere hour and ten minutes !

If this had been a time and not a date, a colon would have been used as in 15:20 and 16:30.So in theory you are talking about 110 years not 110 minutes.


My mind was having a skewed day! :-)

I believe that was also a bad time in history to be a magical practitioner also. They were so witchist back then !

Cheers, Mike.

Now this is my in your dreams car. Apart from merely paying about $8K AUD in luxury car tax, you get two turbos, an amazing set of dual-disc brakes per wheel, shockers the rally guys use, and some very specialised sway and torsion bars. Plus some nice bling.

The biggest problem with this type of car is driver overconfidence. It's the sort of car that takes you closer to the edge of physics and thus with almost no warning that you're about to exceed limits. So the trick is to drive sedately knowing that you have exceptional all weather margins. This is the car for those who suspect all other road users of constant malfeasance ..... moi

Cheers, Mike.

Hmmm .... went to rack & ruin after medically recommended treatments. I see a pattern here. :-)*

Actually I blew the bottom disc ( L5/S1 ) some 16 years ago, when the car flipped as I swung to avoid a head-on with a crazy/drugged driver. Could have been worse. Could be dead now. The neurosurgeon said he could EITHER operate and I would spend six weeks in bed/traction, OR I could just spend six weeks in bed/traction. So I remain untouched by a scalpel. Now I cannot swing a golf club ( though it's arguable as to whether I could beforehand ).

Friends come and go, but enemies and injuries accumulate! :-)

Cheers, Mike.

* this is the sort of opinion that you get for nothing : all embracing, knowledgeable but utterly useless ! A paid professional opinion is exactly the same except for the transfer of funds. That, of course, is useful ....

( edit ) We have a Tarbosaurus at Melbourne Museum which initially interested me greatly because I thought it was Turbosaurus. I mean 'Alarming Lizard' is a reasonable name indeed .... but what about MitsubishiLancerRalliArtosaurus ? [ This is what one buys if one can't afford an Evo ie. me ... ]

Hi Everybody ! :-)

Nice to see you back, Bill ! ;-)

Yes, we do spinal shots DownUnda. Correction : Bundaberg Rum straight down the neck*. Rule #1 in surgery : 'there is no body cavity that cannot be reached with a 14 gauge needle and a good strong arm'. Now we are legally not allowed to flirt with nurses in Australia, due to a class action brought to court by all the other nurses who were not being flirted with ... :-)

Google tells me that Jager is : a German 70-proof digestif. As such it clearly comes under the title of a medicinal preparation, but it seems to have been mislabeled as a munition in some instances.

Many people are alive only because it's illegal to shoot them

I'm thinking of instituting 'Werewolf Wednesdays' as a culling measure. Each Wednesday evening I'll let the packs run - with prepared lists in hand. I could follow up with 'Theropod Thursdays'** for any stragglers. I've just done a quick poll around the office this morning as to who would accept me as a benign dictator. Quite oddly, most said they'd have to think about it! :-)

Cheers, Mike.

* Oh, and for the patient too.

** Velociraptors et al.
