Wow! Your English is excellent! I thought the French resented having to speak English.It's Robyn, well actually Robin, but people have been spelling it with a Y here so I went on with I'm actually from south of France but I've been in Melbourne for 3 and a half years now.
Yes, it seems like a natural way to present the lesson. Start with the basic idea, then give it the full engineering treatment.I really like the fact that this page goes through the whole process of troubleshooting the weaknesses of a simple discrete design. I've always been looking for this kind of approach as I believe it is the best way to learn.
Right. Personally I would throw them all out and buy new ones. They aren't that expensive.This particular case is a bit to extreme though as I am not sure that any of my PNP's are functional .
Sure. I like designing with discrete components. It's the way I learned originally, and even now, very few designs, perhaps none, can get away from discretes completely.I am not 100% sure that this is what happens. It seems like it but I am still fragile with my handling of metering tools so I would double check this finding (if you have a couple of PNP's to spare!). I enjoy this way of learning though, trial / error / observation / conclusion. It helps my artist brain make sense of the equations by being able to "feel" what happens in the circuit. I was watching a documentary about Robert Moog recently and he mentioned this intuitive approach. I guess I got a glimpse of what he meant
Regarding intuitive understanding of voltage and current, I'd like to get your feedback on an idea I posted here a while ago. It's an explanation for voltage, current and resistance that equates them to distance, tension, and stretchiness. A resistor is modelled as a tension spring. The introductory post is at https://www.electronicspoint.com/newbie-questions-t248766.html#post1470672. I would appreciate your opinion.
Cool! She's a barista too, among other things, but she's not working as one now. I'll let her know(re my sister) Well if she is ever around Gertrude St. in Fitzroy she should come to Southpaw. I am barista there, mainly on weekends and I would be happy to shout her a coffee!
Thanks for the links. I'll check out the videos when I'm at home and have proper bandwidth.I just watched this video:. Also going to check the two books I bought (Electronics for dummies & Electronics demystified) for infos about our 5 legged friends (seems like they come more in 10 legged twins these days!).
Edit: Another great op amp video: http://www.youtube.com/watch?feature=endscreen&NR=1&v=OMJ9WGrRf6A
Edit 2: Oh my god this all makes so much sense!Edit 3:
Cool! It's a pleasure to be able to help someone who is so intelligent and resourceful. Compared to many of the folks we get here, you're a breath of fresh air my friend.Thank you again very much, would be great to meet you in person if you pass by Melbourne again.
