Power Supply for Home lab?

The Main reason folks build there own is first and formost for the experiance  (Kinda New EE 101) , it can teach you a whole load about electronics, OpAmps, Power Transistors, Feedback, Transient Response, Voltage References, Temperature stability to name just a few and at the end of it you have something usefull

The second reason is because you have a few of the expensive parts laying arround already and there just the ticket to build a PSU on a budget, Im talking about perhaps a transformer from an old AMP, got a box to put it in, have an LCD or LED display to show the volts and amps (Or an analogue one) etc. Then the cost is minimal for the rest and you still get the benefit of learning and something usefull

If the reason you need one is purly professional / Must have one for the hobby but are an experianced EE then yes, often much cheaper to simply buy one, albeit low end.

My series on building one is aimed at the folks wanting to learn and gain the experiance, and now im going to extend this to making it fully programable, even remotly so it will potentially be comparable with ones exceeding many hundreds of dollars.

You can't go wrong with an LM317 operating in Linear regulation mode!

Making its voltage programmable is as simple as incorporating a I2C/SPI/Serial controlled resistor.

It looks like eash one is about 60$ odd, plus a fee for certificate. I did not look too hard but could not see where it was free, If I can do it for free I would consider running through it for fun

To Peter: It is FREE. when you forgo Certification.  Just enroll yourself, if it asks for Credit Card Info, just close the Browser Window. Hope to be able to bounce Ideas off of you when the Course starts.

I enrolled and ended up totally flattened like a pizza!

It certified me as a Looney!

I added it to my watch list but htere seems to be no future date at this point in time

this is what I see and the dropdown under sessions only shows future sessions and adds me to a wait list. is it possible it does not like me being in Canada or the course is full ??

IDK (I Don't Know) why you got the Screen-Shot that you did.Of course you DID create yourself a Login at the www.coursera.edu, Right? That screen of yours was what I got prior to when offered the again [25JAN16]  AAR there are work-arounds if you do Not want Certification. Get or give me (your) Gmail ID, sent to elyee000@gmail.com IDK whether Canada (or outside USA) IP addresses are singled out? I do not think so, but anything is possible.

To Compact:

You were able to get registered at coursera.edu for the "Intro to Power Electronics" course, Correct? B/C Peter Oakes is/had problems w/ registration. He is I believe is in Canada, while you are in  NZ, correct? AAR in that screen Shot, he posted [17JAN16 923PM] on the Left side of the Photograph are two Receptacles (1-Red, 1-Blk) They are Female receptacles that can accommodate "Banana Plugs". Remember our discussion about Bananas?

I looked at other courses and there ok, shows a registration and everything

Maybe a couple of years ago (Sept 2014) I register with intention to do it and never did ??, and it wont let me do it a second time

Hi Edward,

Have no fear, some of the University crowd have called me a fool and even a fraud.  Unfortunately non read my book, so they really had no basis for their assessment.

My theory only uses algebra, trigonometry and two basic forces.

I doubt that any course on Quantum Mechanics will provide you with an understanding of the science involved.

Your basic 1972 physics book will provide you will the fundamental issues.  QM arose from some scientist attempt to fit their ideas into a model.  Unfortunately, their math does not work.

My approach describes almost all of the effects observed in the universe at the macro and micro scale.  Plus the math works to support the theory.

I am still evolving parts of the theory.  Along the way I have found that many assumptions behind QM are not correct or even feasible.

So I would recommend that you hit your local library, you can find lots of books and articles on QM and the many interpretations of both the theory and its correctness.

I would also be wary about relativistic physics.  I am seeing evidence that Einstein was wrong, but I do not have the time to explore that particular issue.
