See a 3D View of your Eagle Cad Layout

With Eagle3D it is possible to generate a 3D View from your Board Layout. This will help you iron out mechanical clashes, thermal conflicts. Serviceability and Accessibility issues too.

On Panel PCB's Like front/back panels. Usability errors may become visible in this simulation. Connector and wiring layout can be better judged on 3D and strain relief and cable management can be planned in power electronics designs.

In sensitive analog circuits; thermal, leakage or guard rings can be inspected. In RF circuits; the shielding, tracks and components can be studied for unwanted coupling, crosstalk or leakage. Finally safety factors also can be judged keeping the enclosure 3d or cabinet in hand.

Now we have low cost 3D CNC prototype makers. Rapid prototyping - additive or laser erosion. You can probably use this as a input for such a machine. Then you can fix it in a cabinet and complete the Mechanical Simulation. This will save wastage of parts, time and pcb's during prototyping.

Hysteresis - Charles Proteus Steinmetz

He was an American Mathematician and Electrical Engineer. He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers.

 (April 9, 1865 - October 26, 1923)

Charles Proteus Steinmetz

He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to better design electric motors for use in industry.

Hysteresis - Charles Proteus Steinmetz

"Eickemeyer wanted to expand into electrical motors and generators, a brand new field in 1889."

AC hysteresis theory

Shortly after arriving in the U.S., Steinmetz went to work for Rudolf Eickemeyer in Yonkers, New York, and published in the field of magnetic hysteresis, which gave him world-wide professional recognition.

Eickemeyer's firm developed transformers for use in the transmission of electrical power among many other mechanical and electrical devices. In 1893 Eickemeyer's company, along with all of its patents and designs, was bought by the newly formed General Electric Company, where he quickly became known as the engineering wizard in GE's engineering community.

My Notes-

I read about  Steinmetz long ago in a Reader Digest that belonged to my grandfather. It was dated like 1950-60. These issues have become brown and have been ruled by silverfishes.

I cannot find that article but i remember it roughly ......

People from/related to GE had problems with thier electrical equipment heating up a lot. Then they heard of this person of Germany who had mentioned about some remedy to such issues.

They visited him in his loft or some upstairs room where the solution to this problem was discussed and the rest is remarkable history for Electrical Engineering. 

The part of the story i remember most was that in one of his wardrobe drawers, a Mama Mouse had made it her home and was also having her kids here. Not only did the compassionate Steinmetz allowed it to keep her quarters, he even attended to the new family with some food and necessities.

Heard of very few angels like this.

Tutorials on Digital Electronics

These were tutors which i first made at around 1999, improved them many times, it must be bug free by now. Now i ported them to google gadgets too.

Tutorials on Digital Electronics

If you like JavaScript and CSS or want to look at some work i did, study delabs code and
dapj code.
