Every single stinking electron I get from the power company gets sent right back to them. Every fucking one. I've counted them. Same for every other customer. Yet they still charge me as if I'd used them up! It's a rip off.

The power company sends you electrons at some energy level. Your home appliances consume some of that energy. Therefore, the electrons going back to the power company must have less energy, which means they either move slower, or you're returning fewer electrons. If you send back everything that you receive, where is the energy needed to run your toys coming from? You should be able to see a difference between what's going in and what's going out on your electron counter (coulomb meter).   Note: This is 100% pure BS, but it sounds logical.   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

I asked about that one time and they made is clear they had no reason to change.   The average guy on the street has no idea how large a gram is or a ml or a mm or a hectare, even though they are printed on the sides of the things we buy (well, maybe not the hectare).     > OTOH, we call the plug in question 3.5mm as well.

They have come in mono and stereo for a long time. I expect he can still use the plugs he got as stereo plugs. He just needs to short together two sections.

I buy for quality, or at least what I think is quality in my price range. Never could get an American car to last. Started buying the Japan cars around 1980. Did buy a Ford in 1995 and it turned out that model was a piece of junk. Went back to the Japan ones.   Around 1972 I took a tour of the local TV station. They had just gotten in a few Japan Cameras about 6 months before and were bragging on them and how they were going to get more as the money allowed for it.   China puts out lots of junk at junk prices. However I have found some of their electronics to be every bit as good as the Japan ones that have been highly rated for many years. Isn't China where many of the Apple item are made ?   If the American companies would quit paying the higher ups in a company large ammouts of money and put it into better quality I am sure lots of jobs would come back to America. Really looks bad to go to a large company and see a row of almost new high dollar cars for the wheels, and the others old used cars for the workers.

By their actions, Donald and Ivanka clearly believe in the superiority of things made in China, since that is where their ties, shoes, and other things are manufactured. The Donald may promote American manufacturing, but that is as credible as anything else that comes out of his mouth.   He has all the honor of someone who stole the family crest of someone else (only modified by removing the Latin word "Integritas" and replacing it with "Trump"), and who tried to convince people that his self-created Time magazine cover was genuine. It is reasonable to assert that all the Trumpettes are just as truthful, honorable and honest.

Two that come to mind are the spy satellite that pointed up to the sky, and the Mars probe that crashed.   I think the UK is metricated. The older Imperial units appear when they are being deliberately nostalgic, like in historical dramas. The last I heard, Ireland (not a part of a UK) had an amusing mixture where speed limits were in mph and road distances were in km.

I didn't realize they're also referred to as 1/8 inch.     **********************************************************************************       Us "Brits" tend to call a 1/4 inch jack plug a quarter inch jack plug, for historical reasons.   The 3.5mm jack plug is a more recent addition to our language, and is called a 3.5mm jack plug. I have never heard it called an 1/8 inch plug.     The problem as I see it with the old style inches system is that it is in discrete steps, whereas the Metric system is as accurate as you want it to be.   I regularly measure things with metric Vernier calipers. This would give a result of 3.5mm on a 3.5mm jack plug, perhaps 3.51 or whatever, if it wasn't quite the right size. 3.5mm is somewhere between 1/8 inch and 9/64ths using the Imperial scale. I think it is actually closer to 9/64ths.   I'm not sure how you can deal with this - why would you not just measure in mm, rather than say it's a bit more than 1/8 but not quite 9/64ths?       Gareth.

Really looks bad to go to a large >company and see a row of almost new high dollar cars for the wheels, and >the others old used cars for the workers. This whole business of imported goods being junk has been going on for a long time. When the USA was still a British colony all sorts of goods were made here and exported to Britain. They were considered to be of lesser quality than British made goods. And they mostly were. This is because for the most part the goods were made to order. And the British folks ordering the goods were mostly (I seem to have the word "most" stuck in my head) interested in low prices. After the USA was formed the cheap goods were still produced to order and most (Gawd! there's that word again!) production was still owned by the British. After the USA started to become industrialized certain technolgies were prohibited from being exported to the USA from Britain. Eventually the USA became industrialized, we developed our own machine tools, the British lost control of our manufacturing, we marketed our own stuff, and produced goods for internal as well as external consumption, and quality improved greatly. Fast forward to the period just after WW2 and the Japanese were in a similar situation. Their country was devasted and they needed money. Many USA companies started having cheap goods produced in Japan. These goods weren't supposed to be of high quality, the USA buyers just wanted cheap and the quality specs of the goods were lower than domestically produced goods. But just like people everywhere in the world the Japanese have the same intrinsic smarts and abilities and when they could they started to produce their own stuff to their own desired quality. The same thing happened with Taiwan. And Korea (Korea doing to Japan what Japan did to us). Now China. India will probably be next, at least when it comes to heavy industry. Machine tools made in India are starting to come on the export market. As of now they are not so good. But they are cheap. Computer controlled machine tools from India still mostly have Japanese controls. But this will change soon. Eric

However, the harmonic content is small and should not cause a problem.   I think buying one of these might be a better idea: <https://www.harborfreight.com/router-speed-control-43060.html> <http://www.ebay.com/itm/382139367809>   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

It might not matter for a scroll-saw, which doesn't need to operate at very low speeds.   However, the same circuit made with an SCR can work. Instead of putting the motor in the anode leg, put it in th cathode leg (the side the gate is on). Reverse EMF gives you very good speed regulation down to very low speeds.   I don't know if it's possible to do the same thing with a Triac circuit.   Clifford Heath.
