Non metalworking pages now being added to my website

I have been promoted to start adding to my web site the non metalworking contributions to the MEW magazine I made over the 20 years. Typically, Electrical, Mathematics, Timber characteristics, and Photography.

The prompt was because of a contribution to this forum where a question was being asked about the resulting value of placing capacitors in parallel and in series.

So far I have added two items, Basic DC theory and Basic AC theory.

Unfortunately, even basic AC theory is not that simple but I did want to emphasise the fact that Volts times Amps does not give the power consumed (unless a resistive load), an error that I have seen made a number of times when the workshop owner is trying to determine the size of a motor required for a machine.

For those whose understanding of AC theory does not warrant visiting my site but still may like to see some actual values these are for my lathe.

Running just the lathes countershaft

4.28 Amps 360 Watts

Taking a cut of 1.5mm deep at 600 rpm and feed rate of 0.06mm

4.60Amps 662 Watts

That is a 7% increase in current but an 84% increase in power.

My web site also gives the results for running the mandrel but without the cut being taken, Also giving the Power Factor for the three tests.

Thank you Harold, that will be invaluable information.

I have now added a further two items to my website based on electrical subjects

Basic Electronic Theory **LINK**

and

Basic Motor Theory **LINK**

You may also like to know that visits to the website are still rising with January having both the largest number of visits in a day, 645 and during a month, 14350. These not including visits from search engines.

Thanks for your part in this as this forum is almost always the site that provides the largest number of visits in a month via the links on it, around 1000 visits in January.

It has visits from over 100 counties but with the UK and USA making the most visits, both very similar numbers, and far more than any other. Australia and Spain come in 2nd and 3rd

Harold

Thank you Harold, your website keeps getting better and better.

Her's another piece of useless information, but interesting.

Having mentioned the number of visitors to my website I thought I should look how many visit my MEW index, something I do not do very often.

In December  799 visits were made to the index looking at 2035 pages. However, the country that viewed the most pages, 656, about one third of the total was China who appear to be in the top three most months. How many readers of MEW are there, if any, in China, what then are they looking for.

Harold

PS. Thanks Thor

Yeah nice site Harold.

That's a true observation about the Chinese sites but darn it I can't speak any one of their hundred dialects, nor read those squigley lines.

> what then are they looking for.

Customers!

Good basic introduction to electronics Harold. A couple of minor corrections if I may:

On page599.html you refer to SK39 in a couple of places in the paragraph on light sensitive devices I believe that should be SK11. In the same paragraph you refer to "the long standing photocell". A "photocell" can refer to one of many different light sensitive devices. I think this should read "photoresistor or light dependent resistor (LDR)".

Keep up the good work.

Russell.

Harold thank for the links and the information within. One constructive suggestion would be that the font of your text be changed to say something similar to this forum. The reason being anyone with diminishing eyesight like most of us oldies may find it an extra struggle to read. John

I agree Neil, hardly a week goes by without someone from China offering to do business with me, either for me to buy something or to sell their products via my website.

Thanks Russell, you will now find I have corrected the errors.

Thanks for your comments John regarding the font I chose when starting my website. There are about 10 what a called safe fonts in that they are almost certainly to be found on the vast majority of PC's. If one is missing then the viewers PC has to chose an alternative which can cause complications. When I started I just chose the one on the top of the list of safe fonts.

Whilst my eye sight is quite good for my age, 81, I do have very poor hearing so can appreciate the problems that advancing years produce.

However, I will change the font on one or two articles to see what problems result. I know that just changing a font size will not be the answer as even though the pt size is the same the letters will not be the same size either taking up more space, or less. In which case it is required to change the pt size also and even then the space taken may not be exactly as the font being replaced. Even so, I will as I say above give it a try on a few pages.

Of course, the website now has over 600 pages with at least, on average, 2 blocks of text on each one. If I find it quick to change a block of text then I could allocate a small amount of time to do a few each day, starting with those articles that are the most viewed

I will give it a try.

I would ask, have you tried the PC's Zoom facility to increase the print size?

Thanks Harold for your positive response and thanks RJW for you suggestion for the info on the zoom option on the Laptop. I'm using iPad and laptop these days - I find the iPad good for resizing text and pictures. It's either that or go to find my other pair of specs that I use for reading!

John

Does anyone know what the font is that this website uses, have looked at the page source code but cannot see anything resembling an instruction as to what font to use. On the page source code for my site it is very obvious.

Thanks John (RJW) for your comments

Harold

Hello Harold, I think it is Ms sans, a Microsoft system font.

Neil

Harold,

If I understand correctly [which is quite a big if] ... This is the "StyleSheet" that prescribes the font family on the page:

<style type="text/css">.fb_hidden{position:absolute;top:-10000px;z-index:10001}.fb_invisible{display:none}.fb_reset{background:none;border:0;border-spacing:0;color:#000;cursor:auto;direction:ltr;font-family:"lucida grande", tahoma, verdana, arial, sans-serif;font-size:11px;font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:1;margin:0;overflow:visible;padding:0;text-align:left;text-decoration:none;text-indent:0;text-shadow:none;text-transform:none;visibility:visible;white-space:normal;word-spacing:normal}.fb_reset>div{overflow:hidden}.fb_link img{border:none}

As you will see; therere are several fonts listed ... "lucida grande" is first preference, but; if that is not available on the device, then the next one listed is used [and so on].

P.S. ... If anyone knows better, please correct me !!

I'll buy that, it could well be tahoma. You will like:

Neil

Thanks Michail I have found it now on the page source code, too much to search through. Not knowing the font I was looking for I was reluctant to use the Find facility. The first one on the list however, Lucida Grande, is not listed as web safe and is not either on my PC.

I have therefore changed my home page to Tahoma, (second one listed) as a test case, and must admit it looks much clearer.

Perhaps John you may like to look at my home page and see the result.

Unfortunately, with over 2000 text areas on the site, Including link buttons, etc. it will take some time to do the lot. But will start to make progress with the task a little at a time.

Thanks Neil, I was obviously working on this contribution when you posted yours.

John,

I don't know which iPad you are using [mine is one of the originals, now 'frozen' at iOS 5.1.1]

For me: The first available font on the list [see my previous post] appears to be Verdana ... so it will be interesting to know how you get on with Harold's revised home-page.

MichaelG.

P.S.  ... There is a useful font viewer available on the AppStore, with the unsurprising name of Fonts.

It doesn't change anything, but it lets you quickly see what any of the installed fonts looks like.

Thanks Harold. As always, I love your work.

If you are still viewing this thread Johnboy then can I suggest you give my website a visit to look at a few of the pages now that I have changed the font used, at lease for the vast majority of pages, explanation later.

I have changed from Times New Roman 16pt to Tahoma 14pt which resulted in the text taking up very slightly less space. Because of this changes to a pages layout were few and far between so that the time taken was not that great. Also, suffering with a cold, with complications, I was house bound for three weeks so allocated most of this time to the process and have completed it much quicker that I had thought I would.

The reason I say above, "vast majority" is that a few items have lists, or formula, which benefit from being displayed with a mono spaced text. These have therefore been left using Courier New, which is a simpler type face in any case.

For me the original fount was not a problem to me viewing the pages on the web. However, when I am working on the pages I like, if possible, to view the page as a whole. In this case I do find Tahoma beneficial so I have gained something out of the process.
