Building discrete semiconductor and passive designs, using Opamps and Mixed Design Circuits are the first step in electronics. Most consumer Electronics have a high analog circuit content. Even in Embedded Systems the interface design...
a. PCB Assembly. First Inspect PCB for hairline shorts and cuts and also traces of unwanted copper in the edges and repair them. Also Check if all Drill holes & Slots are proper size...
I have made some Web Widgets, these are analog opamp tutors. Interactive Tutorial with Simulated Meters and Potentiometers, demonstrating how Operational Amplifier functions in different configurations. With a few Op-Amps and a regulated Power...
Systematic and Meticulous work has its own Rewards. An Engineers Notebook or a Hobby Experiments Log Book can go a long way in making a Cauliflower out of every Cabbage. (The credits of the...
Series and Parallel Transformers Series and Parallel Connections in transformers. Observe the Dot-Polarity. When windings are in parallel the current capacity doubles. When windings are in series the voltage doubles. Wrong dot polarity in...
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...
