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)
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.
But I have to say that the article below is one of the very best I have read as it is a subject I know little (almost nothing) about and yet it drew me in and got me thinking and learning and left me wanting more.
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...
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.
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?
