This site is where Digi-key has its data sheet for most of its items.
Great place to get the data sheets you need for the parts you wish to use.
Onsemi data sheet site.
Also if you want to know about different parts available is to use digi-key.com or digi-key.ca to see what is available. I personal use digi-key for all my development/prototype projects as they have the data sheets and dimensions of the parts, this allows me to lay-out/build my PCB board before I get my parts.

I remember years ago after a good night of drinking going out with florescent tubes and it was a great way to impress the ladies with some electrical magic.  After doing the trick afew times, it donned on me this may not a be good thing…moved the next week to a area without large power lines running close to my home.

Have a look at this blog at POPSCI magazine:Global warming blog

I like this article on the thoughts of climate change. I believe this more than most articles I have read.

My theory is that what is happening is natural. The planet earth’s ice is melting like it should. And it will happen faster every year. It has to happen this way….or we would have never gotten out of the ice age.

You take room full of ice and surround it with say a 20 C temperature.

Now in time the ice will melt. More ice melts the faster it will melt. Faster it melts the warmer it gets in the room…faster it melts.  This is what is happening with the glaciers and other ice bodies in our world.

In time the rooms temperature will stabilize.

A experiment you can do  if you have a food scale and a small block of ice.  Place the ice on the scale and not the time and weight. Now wait 15 minutes and mark down the time and the weight…keep doing this till the ice is gone. You will find in every 15 minutes the ratio of ice left over the measurement before will become larger every time increment.

So pretty much more ice melts every 15 minute segment then the last 15 minutes segment.

Again, just my thoughts.

Today was a good day to give thanks for warm homes and reliable automobiles.

The thought above make one start to think about the technology of this century. 90%+  efficient furnaces and the electronics that make them so.

Before upgrading our furance we had a 25 year old furnance that worked great even though it was only about 60 percent effiecent.

We had added a Furance Buddy which controlled the temperature of the heat exchanger, this helped the furance go from 60% effiency to about 80% effienct.

Which is a big savings for adding a controller that cost about $300. The installation was easy and fast.  It was a great DIY for someone who can handle a screwdriver and drill one hole.

The unit pretty much paid for itself in one cold Canada winter.

So here I am with a new furance and no more use for the Furance Buddy.

So if you read this have a look at my page showing what I have for sale. Looking to get $50 for it.

Thanks for reading my words.

I am not looking to change the world, but help give the little knowledge I have to the world, so others can build up there knowledge to change there part of the world.

The basic knowledge I have covers:

Industrial Electronics

Repair of above stated

Methane gas well concepts and tools

Apprenticeship Instrumentation (Alberta)

Scada

Data Gathering Systems

Instrumentation sensors and controllers

Communications (SERIAL) between sub systems

Basic circuit design and prototyping
