Resistor Networks


Just added a new page to cover 6-pin LCC Resistor Networks. Yet another page showing a schematic and package style of a resistor network. Currently the page is linked off the 16-pin LCC Resistor Network page.
The new page is a Dual-row LCC package, while the current page is a Quad LCC package. However there is a page that covers a Dual-row 16-pin DLCC Resistor Network, but with no new link yet.
The Resistor Dictionary page the covers the term; Resistor Network Definition.

Looks like the page doing the worst is 8-pin SIP Resistor Network (non-standard connections). With a few page views and no page rank.
I may be able to add the link for the new page to the other related pages in this section.

Panel Mount Resistors


Looks like the small section relating to Resistor Definitions contains about 15 pages now. Really a few more pages, but using different page addresses so I don't see them in my Analytics filter just now. The newest page is linked off the definition of Panel Mount Resistor, as Panel Mount Adjustment Resistors.

The thing I just noticed from the page view data is that the last new page added a few weeks ago on
Resistor Encapsulation has received no page views; added off the page, Damping Resistor.

So what I did was add a short definition of a panel mount resistor, and then added more data and some graphics on a new page; the difference between a paper dictionary and an HTML based dictionary of terms.

I did want to mention that among all the other pages relating to resistors, a number of pages were added that cover Resistor Networks, but they were added under a different section. So there are more than 15 pages in this section, I'm just not counting them here.

SEO hint; it took 7 months before this section received more than 100 page views in a month [from March 1 2008].

RFI Filters for AC Power


There's a small section of pages on the web-site covering Equipment Chassis Design. Maybe a guideline on writing a chassis specification or really a ton of recommendations on what to consider when designing a chassis. That index page lists all the topics so the section of interest can be selected with out going page-to-page.

As a sub-topic of AC power modules, a new page was added to address embedded Power Line Filtering.The page has a few words, but not much guidance yet, but I really wrote it late last night. Wow looks like this is page 56 in that section...

Worst page with only about a dozen hits last year; Water Alarm Units. Maybe because it only contains one sentence of text......

Seven Segment Driver


Following last months additions of Functional IC Schematics. I added a new function showing the internal gate schematic of a BCD to 7-Segment Decoder Driver. The page is also linked of the page covering a few LED Terms. It seems like I had already added a seven segment decoder page but I couldn't find it, maybe I just wanted to add it and never did.

Companies that produce LEDs, and Display Module Manufacturers.

So second new page addition for the new year, and this is blog posting 193.
Page visits are back up to 9,000 per day, and I hope next week will bring them back to their normal 9,500 a-day.

Panel Mount LED Graphics


Like so many pages before, I added a new page to hold a large graphic or pic file.
The new page covers Panel Mount LEDs. Because I already had a page covering LED Terms, it's linked off that page [added Nov. 2007].

Next Time I get to it I'll add some more data, and another graphic if I have one. Of course you could also call a panel mount LED a bulk-head mount or chassis mount LED.

The page relating to LEDs with the lowest page views in 2009 was Edison Base LED Lamp Definitions. Which makes sense, how many people know that the base of a normal light bulb is called an Edison Screw Base. Which also reminds me of the current issue with those LED Traffic Lights. Which happen to use Super Bright LED Components [added in Jan 2008].

When I first saw traffic lights using LEDs and not incandescent bulbs I looked it up on the internet; ending with a blog posting back in 2007 [Super Bright LEDs]. I even provided power consumption data for LED lights [13 watts] and incandescent lights [135 watts]. Well guess what, those LED based traffic lights don't generate enough heat to melt the snow that lands on the glass plate protecting the LEDs. So in the northern states those LED traffic lights just fill with snow until the lights are no longer visible. Opps!

Anyway first new page addition of the year.
