So glad people are enjoying this. I hope I can keep it going. I will do my best.
Thanks so much for reading my article and commenting. I really appreciate the encouragement and glad there is so much interest since it creates a little community.

Good going, I am an electronics guy (not really a softie) and am more than willing to proof read stuff for you. I think the only thing I would say is running a green led from a CR2032 like you were doing could damage the led a red one (older tech) is lightly to last longer with out a resistor.
Had a bit more of a read and you do mention Resistors my bad...

Thanks for reading and for taking the time to mention that I talk about resistors in that first odd experiment. 
Interesting to hear about the green versus red led thing though too.
I know that first experiment is a bit odd since we are using a bit too much voltage on the LED.
also, I really appreciate someone with more experience in electronics reading and glad to hear any input you have.

Umm, one thing from giving the article a read you measure the battery voltage open (not underload) this can leads to the open terminal voltage being read not generally what you need to know from a battery. This can confuse beginners (it caught me, until I was told). The red LED being older can be a bit odd, also you can use them as photo diodes (bit cheaper, not quite as sensitive)

Thanks very much for mentioning this. I will look into this further and make the necessary changes as I understand them. Really appreciate it.

His last series of articles, BOOK, was excellent as well. I'm looking forward to following this one as he works through it.

Interesting. Reminded me of basic electronics we studied during first semester of engineering (mechanical). I hope CP and that article are around for next 10 years so I can introduce my son to it. I guess it is far better than the way they would teach him at school.

I just say his UWP series yesterday (and left praise for that too).
Read this first part of electronics and agree, this one is also well written with relevant and useful examples.

Absolutely. IMO, it's a rare thing to find someone who not only starts a journey but can write about it in a way that is captivating, interesting, entertaining, and informative way.
One of the problems I have found in the past is that there are few resources which just start at the beginning...
@raddevus nails it on the head right there!
And thank you for the mention too!

I really appreciate all the comments : they are very encouraging.
I'm also really happy that so many others are responding to the article too because I can see there is a great community of people out there who are interested in these similar subjects which hold so much interest for me.
To be mentioned in the same company as these other fantastic CP authors is humbling and encouraging also.
thanks so much.

When I attempted to post my latest article : Practical Electronics For Makers (Part 1 of N)[^] the hamsters went crazy and the article was lost.
However, previous to hitting the publish button I grabbed the HTML from the article and saved it locally. Wahoo!!!
Ain't no hamster what can stop me.

We have to be kind to the hamsters. They are watching you know. Well, at least pretend to be kind.
I sent a link to the article to my son, as my grandson may be interested.

Blame Chris. He's still feeding them the fermented seeds they got for Christmas.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Hey! Fermented seeds can be good for you. The Japanese thrive on fermented soya seeds, which they call Natto. Very nutritious. (But smelly!)
But I like fermented, smelly milk products, like cheese and yogurt, so who am I to criticize the smell of Japanese cuisine?

They certainly can. I regularly drink extracts of fermented barley and hops in medicinal quantities. They are the only things that keep me sane in these insane times.

oh alright.. i got that what you mean thanks

I'm beginning to believe these hamsters are heavily guarded and copyright protected and trademarked too, because I googlec "codeproject hamsters" as an image search and got nothing.
Anyone, got an example snapshot?

I don't see one of These pics where the hamsters -what I remember - nibble on the hardware...

Look at the very first picture, upper left on the page. At least that's where they appear in my browser.
