So 1.5 x 15 x 10 = 225 Joules delivered "per shot"

Now a cattle "electric fence", similar voltage, 3 joule unit will give a pulse every couple of seconds.
A 3 joule "energizer" will power many kilometres of electric fence.

Defibrillator will give up to around 360 joules per pulse, which is ballpark enough to make a corpse sit up.

10 to 50 joules is regarded as dangerous.

Electric fence + human is invariably hand / arm contact, not across the chest like a taser, even so, you won't like a 3 joule pulse every second, not actual real pain, but most unpleasant.

Taser delivers HV energy at a rate 75 times higher than a cattle fence energizer.

Which is a bit like saying that a 44 magnum (1,000 ft/lb) delivers energy at a rate 75 times higher than a 12 ft/lb air gun.

Mod parent up.

If you only found one problem, it is because you stopped looking, it is very rare to find only one problem with hardware, as in only one item may actually be defective, but at least one other item is getting close to the limits of spec.

You're right, I splashed the cash and bought.

Let's say you have a small machine that has an XYZ envelope of 300mm a side, that's 27,000,000 millimetre cubes, or unique XYZ positions the tool and toolpath can follow.

1mm precison is worthless, at 0.1 mm precision you just went up to 27,000,000,000 unique positions, at 0.01 mm precision you just went up to 27,000,000,000,000.

You're probably not going to get a linear speed in excess of 1 metre second on anything even remotely hobby, 250 mm min is more like it...

at 0.01 mm resolution that's 25,000 positions in 60 seconds, that's approx 417 a second

we've got 27,000,000,000,000, so / 417 = 18 million hours to traverse all 27 x 10^12 points.

even assuming you had that kind of time, your machine is burning electricity at several cents a kWh... do the math.

So you can see how optimised tool paths, and so on are literally god when it comes to CNC.

Sure, there are free OS alternatives to the stuff I paid for, but I don't have the time left to live, nor the inclination to pay the electric bill, that using the free OS alternatives requires.

HTH etc

... are exempted, along with Iraq and Iran...

but Isreal has more nukes than everyone except USA/former USSR, and they aren't even mentioned.

Yet another example of US foreign policy that will go down very badly in the arab / muslim world.

Hell, it doesn't go down very well in Europe.

and I mean really shit, every 50 miles you had to open the hood/bonnet and tinker with it, and even when it was running nothing worked anything like it should have done when new.

I learnt to drive a car that had, at one time or another...

a/ no clutch
b/ no starter
c/ no brakes
d/ no hand/parking brake
e/ dodgy steering
f/ throttle / carb problems, inc throttle cable breaking or jamming open
g/ carbs that iced up at whatever throttle position you happened to be on.
h/ dodgy tyres
i/ no syncromesh on the gearbox
j/ now power assist on the brakes or steering
j/ etc etc

compared to the kids now who start out with relatively new cars, basically I learned to drive and control a car, by having to cope with cars that pushed the envelope, whereas everything a driver encounters now is within a very very small performance envelope.

The old Series II Land Rover had 3 gear sticks, one high-neutral-low range, one two-none-four wheel drive, and one reverse-first-second-third-fourth, which also had false neutrals, no power steering, no power brakes, and frankly, even in a country where the vast majority of drivers are stick shift, probably less than 1% of drivers can just get in it and drive it, and this is with a (worn, but working) synchro main gearbox.

I've also driven auto trans, from RE Olds through Merc to press button selectronic "drag strip" shifters, also floor stick, column stick.

I've driven vehicles that you had to adjust ignition timing and mixture manually as you went along, and even some you had to manually pump the lube oil.

So basically, if you have ever been taught to drive PROPERLY, you can remain in control of the car, no matter what happens, short of the wheels literally falling off.

The problem always comes back to driver ed, particularly given the fact that one car model is sold worldwide, but there are VAST differences in driver ability, attitudes, roads, traffic, etc etc.

plus I can buy and fit / swap batteries with one button, use the webcam, burn dvd's, watch true HD on the 1920x1200 screen, etc etc etc...

obviously I haven't drunk the apple kool-aid

Will Hartnell was actually a very sick man, hardening of the arteries, the plot device for fluffed lines/ memory was actually his idea to cover for this and to save re-takes on a too tight schedule, it was only later that he was diagnosed and the reason for his failing memory and other problems became clear.

Were the best, by far.

Watching it on an old 405 line UHF black and white set, this was before man had walked on the moon, the TV worked on thermionic valves, back in those days it was genuinely good, the scripts were good and the stories pushed the envelope of props and effect to the limit, and often moved the boundaries.

Nowadays it is a bunch of feeble, lowest common denominator camp crap.

You only have to watch the original movie Gone in 60 seconds and the awful remake to understand what I mean.

and tic-tac-toe

nuff sed

I may be wrong, but from the UK perspective this is not "NHS Lite" socialised healthcare, rather this is the wetware equivalent of compulsory motor insurance, now applied to human beings...

Nice civil liberties you have there citizen, shame if anything happened to them, better buy this here medical insurance, know what I mean?

Sounds like this bill has nothing whatsoever to do with medical treatment per se.

One small step from the RIAA et al doing the same thing.

of things about to go wrong in a big way...

So, you are basically stating for the public record that YOU PERSONALLY ACCEPT TOTAL RESPONSIBILITY for every last byte of data stored on your computers...

I hope your computer are stocked in a vault to which only you have physical access, and which is blocked from the net, and which doesn't have any mains power.

After all, you just stated you believe it is an absolute offence with no possible or acceptable defence.

Good of you to volunteer me for the same bullshit without first asking me though.

Sounds a lot worse as a charge...

"Yes M'lud, Mr Taco is charged with making these images"

sounds a lot worse than

"Yes M'lud, Mr Taco is charged with owning a computer running Microsoft Windows 98 and Internet Explorer 5, which, when Mr Taco visited the website in question, caused cached copies of the images in question to be stored temporarily on the hard disk, in an area of files not used or accessed directly by Mr Taco, but by the Microsoft products aforementioned"

The latter is also sounding a lot weaker if you're trying to sell yourself as tough of peedos, anything for the childruuun, vote for meeeee!

I did a stint at teaching, the modern way.

True story this.

Class was finishing up in the Head Of Department's class on my first day as lecturer.

Head of Department had been lecturing about 2 and 4 stroke cycles, petrol and diesel etc.

"country bumpkin" student puts hand up and asks about 2 stroke diesels.

Head of Department smiles condescendingly, entire class laughs at "country bumpkin", Head of Department says something condescending and superior to "country bumpkin"

By this time I have forgotten that Head of Department is running late and into my class time, I've forgotten he is Head of Department, I have forgotten it is my first day as Lecturer, well, maybe not forgotten, but don't care.

I step forwards, and say to Head of Department in a loud and clear voice (class is now silent) "have you got a phone in your office?"

He looks puzzled... meh

I continue, "because you ought to ring the United States, Detroit Diesel specifically, and tell them there is no such thing as a 2 stroke diesel, which will be an interesting phone call, seeing as they have been making the things in VAST numbers for fifty fucking years."

Needless to say, my teaching career was short lived.

Dude, apprenticeships were tough in my day, they were MEANT to be so, and I had it easy, my father's parents had TO PAY HIS EMPLOYER for the first two years, basically for permission to come to work, no wages, because you're economically useless when you start out.

IF YOU GENUINELY want to learn, find some old retired guys in your field, or a closely related one (a 60 year old turner who learned his trade before CNC can still tell an aeronautics guys a shit load about materials and engineering) and start hanging out with him.

After a while you'll start to learn, nothing new under the sun, it has all been done before, usually better.

Really, please make me a 3 phase 380 VAC supply at 60 amperes with a kWh cost of 10 cents or less and deliver it to the point of sale with your "software" and have it "run directly".

I would also like your "software" to "run directly" without the need for me to purchase any hardware that is manufactured overseas.

Thanks in advance.
