Analog is the first thing in electronics. Valve Radios had Amplifiers and RF sections that were analog. Even the first computing methods are analog. Analog is close to Real Life parameter behavior.

Here are some Test and measurement notes. These ideas come from practical experience. But the jots are not in any order but are quite important.

Product Design includes Schematic and Firmware Design. The Mechanical Engineering that goes into making the enclosure and internal construction is also important. The Electromechanical design which is made of electrical circuit, pcb, panel-parts and...

In Switching Power supplies and RF Circuits, the coils and transformers have many types of cores. Ferrites, Powder Iron, Air and others. These are much smaller and lighter for the same power that they...

Capacitors ares like reservoirs of charge. In the Water Analogy they are like your Overhead Tank or Sump. It can be like a Lake or Pond, when water is the charge. Ceramic capacitors are...

In Test and Measurement and Industrial Process Control a common factor is instrumentation. The measuring aspect is common to both. T&M instruments are used in Testing, Research,Automated Testing, Troubleshooting and Servicing.

Resistors start from Wires to Wirewound Types. Carbon Film Resistors are most Common, Metal Film Resistors are more stable and accurate. We have now SMD types with lower power some are Laser Trimmed Types...

There are Web widgets related to learning electronics and also demonstrating the subtle aspects of Product Design Technologies. This blog also has the widgets made by delabs around 2005. These demonstrate solutions for improving...
