HGV=Heavy Goods Vehicle, which is split into 2 classes, 1 & 2. Class 2 is for rigid trucks up to 26 tons. Class 1 is for articulated vehicles up to 44 tons.

So filled with a load of bubble wrap it isn't a HGV any more? But loaded with lead bricks it is? Gotta love slang and acronyms. STAA for instance.

That's close enough to ours. However, one will rarely see Road-Trains (Class 1 articulated + trailer) over here & the ones that are seen, are foreign vehicles.

As for the loads, they don't count in the definition of HGV as should you check, you'll find its "unladen weight".

However, Yanks always have to be different & bigger :)

Gary you are just being perverse and deliberately awkward.

Just the King's English at work. Wasn't said as maximum gross vehicle weight. See how simple it is to not confuse?

Actually these days it is the Queen's English, but I'll have a word and get her to let you off, just this once.


One of these days someone is going to have to explain to me how one person can own a language.

What they speak in Wales even when trying to speak English is not readily decipherable as English. This I know to be true, about 45 years ago a rugby team I was on had a Welsh back and even the Englishmen could not understand him.

An interesting idea.....

Plastic Electronics

Just the kind of stuff open-source printing projects such as Rep-Rap focus on...

(I have all the parts I need for my machine, I'll start building it next month or so, lately I've been soldering and bench testing the electronics. But my goal is to have a unit that can do plastic parts, and circuitry. maybe in a few years, both at the same time into one piece)

No, they don't own a language. They do however own "rounded corners" apparently.

I'm surprised they didn't take on Intel when they brought out the i3/i7 range.

Message 1315453 - Posted: 15 Dec 2012, 6:26:39 UTC

I am a bit bewilderd about two of my computers. my old I7 920 at 2.67 GHz. with a Nvidia geforce GTS 250 and running lunatics has a rac of 8581.
My new build is a I7 3770 at 3.40 GHz. and NOT running lunatics, Has a rac of 4339.

Is it the GHz that makes the differance or something else.
I havent even installed the EVGA 550 Ti in the new build yet. I wanted to see what I could get out of running stock untill Lunatics can resume Its Op apps.

I think sometime after the new year that card will go in and I will see what kind of beast I have.

May I relate my experience.
A GTS250 running Lunatics 41g is good for around 9k RAC.
My "Daily Driver", Q9550 + 2x GTS250's running the Lunatics AK_V8b2 SSSE3 for the CPU and 41g for GPU had an RAC of around 24k.

When I replaced the GTS250's with two GTX550Ti's the RAC jumped to around 33k. Same drivers and apps, the only thing that changed was the GPU cards.

But my I7 920 is running CPU and the GTS 250. Before we had all the server problems Ive seen the rac up tp close to 14,000. And this is with running lunatics.

My I7 3770 is just running CPU with out lunatics or a GPU and the rac is about half. Id say that is a pretty good performance.

So is it the GHZ or the architecture of the chip, Or both?

The decrease in nm means they have found ways to decrease the size of each transistor. This enables them to run colder as less volts and/or current needs to be used. As temperature is proportional to power and power is the product of the voltage and current the cpu will run cooler.

There is also a maximum power rating of cpu's ~130W. This is about the maximum that can be handled by air cooling in normal conditions, worldwide.

The higher the frequency, GHz, enables more operations/sec, therefore the cpu will be more powerful. But the increase in performance of a computer due to the frequency is not always linear as the memory and the bandwidth to the memory play a large part in computer performance. That is why most CPU's have large L2 and L3 cache onboard.

You will also have noticed that the frequency that cpu's operate at hasn't increased since the days of the P4.

Therefore as the speed hasn't increased the lower power from the reduced nm means more cores, or larger memory caches, can be used.

As most people do not need more cores, most of the benefit will be seen in lower power consumption.

Except for people using special software like video processing more cores would be anything more than a bragging rights. Unless you are a BOINC nutter, like us.

Through the last month I have been working on my 3d printer. I've come a long way now from this:



to that:



and now the fully functioning unit:



All that is left is to do some calibrations and some further changes to the firmware, then some actual printing calibrations. It was so nice to finally get it all together and play with it just a little, sending codes to the electronics via USB, making sure everything was functioning and wired properly.

All brought to you by open source, and some time and experience of course. :-)

And the printer has been-a printin'

I have been pushing the quality further than most 3d printers do, so my prints are slow and my issues are finicky ones.

But, this is the kind of work I've pulled off so far:

Here's a Yoda bust, blurry pic of the printer in action.


And here's an Android, they're coming for you!



I've got a way to go with calibrating it within the perfection I'm looking for, but so far it's going pretty well.

Happy crunching and whatever other geekstuff you are in to!

That's a really good question. I guess in the meantime probably just my own personal amusement.

The main goal was to have a way to make custom parts for myself for various electronic and computer based projects.

The next time I plan on making something ugly out of duct-tape and cable ties, the wifey will be happy to see me neaten it up with a custom case/mount/part whatever.

I guess I just wanted to expand what kind of things I could work on in my own shop. For now I'll just print hordes of little Androids, and take over the world.

In the future, I could make it profitable by making models for people, or even parts that aren't mass produced/hard to find. I plan on buying some glow-in-the-dark material, and using it to produce some ebay rasberry pi cases in a currently unoffered 'color'. (Then again, as the popularity and ease of use grows in the 3d printer market, it may not be long until everyone has one...)

I will need a second, and probably third unit if I wanted to produce small goods at a volume for sale.




Note on materials. These printers use (typically) ABS filament and PLA filament. I'm sticking with the PLA for now, as it's totally non-toxic and biodegradable. They say it is "hard to recycle", but as I save my waste it can be recycled with proper equipment by being chipped, melted, and reused.
