Simple electronic projects

Do you want to have electronics skills? The best learning is making a simple electronic project. There are over 250+ posts on my site. I like the simple electronics projects that worked surely. You also are like me. Because I know that you need to have a great experience.

Simple Electronics Project banner

Searching them as you want in categories, may be difficult for you.  So, I will show you the top 100 list of projects.

I like small or mini-projects using simple and low cost. Like diodes, transistors, digital electronics ICs and more.

Imagine you need a LED flasher circuit. You have many choices to do.
first, transistors circuit. Second, 555 timer version. And later, Arduino.

Which is better? For me, Easy and cheap is better. I pick the transistor version first. Then, IC-555 or op-amp. For Arduino is so expensive for only LED blink.

Who is suitable for these? …

  • Those who interested as a hobby
  • Student schools
  • ECE(Electronics and Communication Engineering)
  • EEE(Electrical and Electronics Engineering) students
  • Those who interested as a hobby. Some are over 60 years old love Electronics too.
  • Also, study homeschooling the same us.

It is a good learning by doing!

If the project does not work, we learn the solution. It is not a failure, but it is another way of learning.

Most simple electronic circuits, we assemble on universal PCB Board. Because cheaper and faster than buy KITS.

If you try to create these mini electronic projects with small circuits. And get the results out.

Please remember to share it with us.

Mini Projects for beginner

Any success or failure is a good learning

I tell you frankly that I did not test all the Electronic circuits Projects shown on this website. So there might be some circuits that do not work well as they should be.

Anyone who tests and finds some projects that do not work at all or do not work well. Please inform me so that we will find out together what the problems are.

Anyways, some friends have built some projects as same as those shown on the website. And found that they worked well.

I believe that any success and failure of the projects are all good learning.

Inverters

If you want to convert a DC low voltage to AC volt output.  You should these circuits. See Top 10 list below.

  • Simplest Inverter circuit using transistors
    Very simple 50 watts inverter circuit using MJ2955

    If you have only 5 minutes, but you need to use a small light bulb with a 12V battery.  How to do it? This will show build the simplest inverter. Just 2 transistors, 2 resistors, and a transformer only.
  • Small high volts shock
    high volt shock using transistor-2SC1815

    If you want to make a funny circuit for people. This circuit may make a laughter.  It is a small high volts shock circuit. The output is low current. It is not harmful to people. On circuit has a few components just two small NPN transistors, 2 resistors, and a transformer. So easy to builds and inexpensive!
