Hello there! Do you know if they make any plugins to protect against hackers? I’m kinda paranoid about losing everything I’ve worked hard on. Any recommendations?
Hi Nguyet, I use one called Wordfence Security. Seems to work OK, and it’s free. I guess I’ll never know for sure if it works or not unless I get hacked.
Dude these articles are great. They helped me a lot.
You’ve been very helpful to me. Thank you!
Hola, volia saber el seu preu.
David, I only speak English, but if you were asking what the lessons cost, there are no charges. Just go to electronicsforfun.com and read whatever you want., John
Good day! Do you know if they make any plugins to safeguard against hackers?
I’m kinda paranoid about losing everything I’ve worked hard on.
Any tips?
Hi Jenny, I use one called Wordfence Security. Seems to work OK, and it’s free. I guess I’ll never know for sure if it works or not unless I get hacked.
All we can do is keep backing up our work just in case.

I think you and I are about the same age. LEDs came out when I was in high school. As a kid, I read a number of books about electronics theory, and built a couple of things from schematics, but I always wanted to connect the theory with the reality: Why does that circuit work that way?
Wow! So far, I just looked at the pictures of the components. I am already impressed. I can’t wait to get to the course itself. Thanks!
Hi Jim, it’s just a forward biased diode. When conducting, it heats up and emits light. A process called electroluminescence.
I think all diodes actually would emit light, but LEDs are engineered specifically to do that, and of course they have a transparent covering.
Thanks for your positive comment on my component section.
Great, thanks for sharing this post.Really thank you! Cool.
Hello. Great job. I did not expect this. This is a great story. Thanks!
Hmm is anyone else experiencing problems with the pictures on this blog loading? I’m trying to determine if its a problem on my end or if it’s the blog. Any suggestions would be greatly appreciated.
I haven’t heard any other complaints, but I’ll try to help you. Is it all pictures or a paticular lesson, or certain photos?
Thanks, EFF John
Crossword Puzzle
Hi, I just posted a crossword puzzle using electronic terms.
To check it out just click it on the menu. Thanks, John
Lessons 3 thru 6 now have videos.
Thanks, John
Posted a new video for lesson 4, Ohms Law part one. It goes over the calculations involved in a series resistor circuit. The calculations are explained step by step so a fourth grader could easily understand.
Then, after the calculations are complete, a meter is hooked up to show what the actual readings were.
Sorry for the delay,
Thanks,
John
hope you are getting better
hope you will be well soon
That is very kind of you.
Now that they have my meds right, things are rapidly improving.
Thank you very much.
Due to having major surgery, I will not be able to add any more videos until probably mid to late September, God willing. Thank you.
Just wanted to say hi and thank you for putting this together!
You are quite welcome!
Looking forward to taking this class with my son this fall. Thanks John!
Thanks Fred, John
In Basic Electricity, you displayed a model of an atom to display the setup of a basic atom of Hydrogen. However, the atom is described as (and displayed in picture) an atom of Helium, with 2 electrons, 2 protons, and 2 neutrons. The Hydrogen atom has 1 proton, 1 electron, and no neutrons, only isotopes have it. Can you clarify
Asterwind, THANK YOU!!
You are of course, absolutely right! I had an image of a Hydrogen atom at first, but it wasn’t one I felt good about using. The images I use here all all either from Wikipedia, with a Creative Commons license, or created by me. So when I couldn’t find a Hydrogen atom on Wiki, I changed the image along with the description of how many protons, neutrons, and electrons, but forgot to change the name from Hydrogen to Helium.
I must apologize to my readers for that and credit Asterwind for catching my mistake. Good job Asterwind!
The rest of the lessons for THIS Basic Beginners course are now all online. The FUN STUFF will be experiments shown on videos, and I am just starting them. They will start showing up by July 31.
After that I plan on starting more lessons taking things to the next level. Thanks for looking, John
