What does it take to be an electronics hobbyist?

Electronics is about IoT, microcontroller and microprocessor. Right??

Wrong, electronics ain’t about coding an microcontroller that is the job of CS guys. I know that skill is important but that ain’t your stream. you are an electronics hobbyist

Building a project from Arduino is a child’s game students even a 6th class student can also easily learn how to code Arduino and build fantastic projects. The electronics person have these skills as well as a lot more.

There are different skills that electronics hobbyist should know.

Some of them are listed below:

  1. Circuit Designing

    The process of circuit design can cover systems ranging from complex electronic systems all the way down to the individual transistors within an integrated circuit. For simple circuits the design process can often be done by one person without needing a planned or structured design process, but for more complex designs, teams of designers following a systematic approach with intelligently guided computer simulation are becoming increasingly common. In integrated circuit design automation, the term “circuit design” often refers to the step of the design cycle which outputs the schematics of the integrated circuit. Typically this is the step between logic design and physical design.

    Formal circuit design usually involves a number of stages. Sometimes, a design specification is written after liaising with the customer. A technical proposal may be written to meet the requirements of the customer specification. The next stage involves synthesising on paper a schematic circuit diagram, an abstract electrical or electronic circuit that will meet the specifications. A calculation of the component values to meet the operating specifications under specified conditions should be made. Simulations may be performed to verify the correctness of the design.

  2. PCB Layout Designing

    A printed circuit board (PCB) mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.

    Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes.

    Alternatives to PCBs include wire wrap and point-to-point construction, both once popular but now rarely used. PCBs require additional design effort to lay out the circuit, but manufacturing and assembly can be automated. Specialized CAD software is available to do much of the work of layout. Mass-producing circuits with PCBs is cheaper and faster than with other wiring methods, as components are mounted and wired in one operation. Large numbers of PCBs can be fabricated at the same time, and the layout only has to be done once. PCBs can also be made manually in small quantities, with reduced benefits.

  3. Debugging a circuit

    Debugging is the process of finding and resolving defects or problems within a computer program that prevent correct operation of computer software or a system. Debugging tactics can involve interactive debugging, control flow analysis, unit testing, integration testing, log file analysis, monitoring at the application or system level, memory dumps, and profiling.

    When a complicated circuit is first built, is not uncommon for the circuit to be non-functional, due to wiring/connection errors, faulty parts, and/or incorrect equipment settings (e.g. wrong power-supply settings).  The process of finding and correcting these problems is called debugging.   It is very easy to get overwhelmed by the circuit complexity and to get lost in the myriad of possible sources of error. However, it is not difficult to debug a circuit if you approach the problem systematically.  Like a doctor examining a patient, an electrical engineer should find the cure for a malfunctioning circuit by observing, measuring, posing and testing various hypotheses, until the error(s) is (are) identified and corrected. We’ve already learned how to use two of the basic electronic measurement tools – the digital multimeter (Experiment #1) and the oscilloscope (Experiment #2); these will be our tools for debugging electrical circuits.

  4. Soldering and De-soldering

    Soldering , is a process in which two or more items (usually metal) are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Soldering differs from welding in that soldering does not involve melting the work pieces. In brazing, the filler metal melts at a higher temperature, but the work piece metal does not melt. In the past, nearly all solders contained lead, but environmental and health concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes.

    In electronics, DE soldering is the removal of solder
    and components from a circuit board for troubleshooting, repair, replacement, and salvage.
  5. Fixing home appliance’s small circuits

    This skill is must if you are an electronics hobbyist as if you can’t repair a stuff that means you don’t have skill and understanding of the circuit or its functioning. You should know how to read a resister, capacitor and inductor ( yes those also have color codes ). Used IC, 555, gates (TTL/CMOS, etc) .

Ahh that’s too much for an electronics guy. No that is just a beginning I haven’t listed all there.

Electronics hobby is not just about the coding of a microcontroller and connecting few sensors or modules with some pre written library. Its about enhancing the circuits using and understanding the building blocks of big things in deep details and making new tings.

Go buy yourself a basic kit and start working on electronics not CS. Solder your components for the PCB that you designed from your own made circuit and make it work, I am sure you will love it.

What do you think is the reason of decline in electronics hobbyist? I will discuss it in a later article.
