Scientific Optical Diagrams

Randal did a series of scientific illustrations for Dr. John Delly, scientific advisor to the McCrone company in Westmont, Illinois. This diagram of a Biaxial Indicatrix was used in a training manual for lab technicians to learn how to identify optical light refracting properties of crystals. The reason this is important is that forensic labs get lots of different “white powder” substances to identify. One part of identifying what the substance is, is by studying what happens to light as it passes through a crystal of the substance. This is often done in a forensic lab environment using sophisticated optical microscopic equipment.

Oil Filter Diagram

An automotive aftermarket manufacturer required a diagram illustration to show how a new type of cellulose fiber could filter automotive oil better than previous competitive products. This is a sepia line art drawing on D’Arches watercolor paper, with Windsor & Newton watercolor washes added by hand.

Castle Keep Cutaway

Randal has been asked to provide illustrations in many textbooks. This one was done for an elementary textbook on the Castle Keep. It is a cutaway diagram showing the floors and various typical activities inside the Keep.

ASP.NET Architecture Diagram

Seems like I am always making these little sketches to show people I am talking with, some of the ideas and concepts behind the type of websites we build at BIRKEY.COM. I made this sketch recently when explaining the difference between a typical classic Microsoft .ASP/SQL Server website architecture, and one that incorporates the newer Microsoft ASP.NET technology.

  • The box labeled “Front” at the top of the diagram represents a public website. Could be any size, large or small.
  • The “can” at the bottom represents a SQL Server database that is behind the scenes. The website user really doesn’t know or care that it is there, holding all the data for the website.
  • The middle area represents what can be done with ASP.NET technology. The boxes represent little “engines” of code that do specific things. One might process a credit card. One might add an item to a shopping cart. Another might list items on a page with a thumbnail image next to them. The list is endless.

The point here is that with ASP.NET, all these “engines” can be ready at anytime for use by themselves, or in combination with other “engines” to perform website tasks, and features. This lessens the amount of special code that needs to be placed inside the actual web pages represented by the top box. It is a far more efficient, and much faster technology, especially the more complex and complicated a website may be.

Just thought you might like to know that.
