Are you looking for a mini project? You want to build the circuit diagram with the PCB layout. My site may be the one choice for you. We have a collection of the mini project more than 200 projects.
Who is suitable for these mini projects?
They are ideal for…
- Student schools.
- ECE(Electronics and Communication Engineering)
- EEE (Electrical and Electronics Engineering) students
- Those who interested as a hobby
- Also, studying in homeschooling like us
It is a good learning by doing!
If some project does not work. I am sorry to hear that. But you will learn the solution. It is not a failure. But it is another way of learning.
Most circuits assemble on universal PCB Board. Because of cheaper and faster than buying KITs.
If you try to create these electronic projects and get the results out. Please remember to share it with us.
It will prevent the speaker from too over high power output may speaker damaged it use transistor and relay cut off as safe.
This is DC Power supply 0 30v 5A,Adjustable regulator, output 5A. It use LM723 DC voltage regulator IC + 2N3055 power transistor x2 to increase current up.
LM317, 3A adjustable voltage regulator circuit diagram
Output: 1.2V to 20V, and 3V,6V,9V,12V
High quality, 3A adjustable voltage regulator. Using LM317 and 2N3055 so easy and cheap. Adjust voltage in steps 3V, 6V, 9V, 12V. And In fine, 1.25V to 20V.
